The source files for CCITT conversion routines in this directory are: g72x.h header file for g721.c, g723_24.c and g723_40.c g711.c CCITT G.711 u-law and A-law compression g72x.c common denominator of G.721 and G.723 ADPCM codes g721.c CCITT G.721 32Kbps ADPCM coder (with g72x.c) g723_24.c CCITT G.723 24Kbps ADPCM coder (with g72x.c) g723_40.c CCITT G.723 40Kbps ADPCM coder (with g72x.c) Simple conversions between u-law, A-law, and 16-bit linear PCM are invoked as follows: unsigned char ucode, acode; short pcm_val; ucode = linear2ulaw(pcm_val); ucode = alaw2ulaw(acode); acode = linear2alaw(pcm_val); acode = ulaw2alaw(ucode); pcm_val = ulaw2linear(ucode); pcm_val = alaw2linear(acode); The other CCITT compression routines are invoked as follows: #include "g72x.h" struct g72x_state state; int sample, code; g72x_init_state(&state); code = {g721,g723_24,g723_40}_encoder(sample, coding, &state); sample = {g721,g723_24,g723_40}_decoder(code, coding, &state); where coding = AUDIO_ENCODING_ULAW for 8-bit u-law samples AUDIO_ENCODING_ALAW for 8-bit A-law samples AUDIO_ENCODING_LINEAR for 16-bit linear PCM samples This directory also includes the following sample programs: encode.c CCITT ADPCM encoder decode.c CCITT ADPCM decoder Makefile makefile for the sample programs The sample programs contain examples of how to call the various compression routines and pack/unpack the bits. The sample programs read byte streams from stdin and write to stdout. The input/output data is raw data (no file header or other identifying information is embedded). The sample programs are invoked as follows: encode [-3|4|5] [-a|u|l] outfile decode [-3|4|5] [-a|u|l] outfile where: -3 encode to (decode from) G.723 24kbps (3-bit) data -4 encode to (decode from) G.721 32kbps (4-bit) data [the default] -5 encode to (decode from) G.723 40kbps (5-bit) data -a encode from (decode to) A-law data -u encode from (decode to) u-law data [the default] -l encode from (decode to) 16-bit linear data Examples: # Read 16-bit linear and output G.721 encode -4 -l g721file # Read 40Kbps G.723 and output A-law decode -5 -a alawfile # Compress and then decompress u-law data using 24Kbps G.723 encode -3 ulawout libsndfile-1.0.28/src/G72x/g723_40.c0000644000175000017500000001175212677561544013334 00000000000000/* * This source code is a product of Sun Microsystems, Inc. and is provided * for unrestricted use.

This new interface also allows samples to be processed in blocks rather than on a sample by sample basis like the original code. * private.h Added prototypes moved from g72x.h. Changed struct g72x_state to a typedef struct { .. } G72x_PRIVATE. Added fields to G72x_PRIVATE required for working on blocks of samples. 2000-06-07 Erik de Castro Lopo * g72x.c Fixed all compiler warnings. Removed functions tandem_adjust() which is not required by libsndfile. * g721.c Fixed all compiler warnings. Removed functions tandem_adjust_alaw() and tandem_adjust_ulaw () which are not required by libsndfile. Removed second parameter to g721_encoder () which is not required. * g72x.h Removed in_coding and out_coding parameters from all functions. These allowed g72x encoding/decoding to/from A-law or u-law and are not required by libsndfile. Removed unneeded defines for A-law, u-law and linear encoding. * g723_16.c Removed second parameter (in_coding) for g723_16_encoder(). Removed second parameter (out_coding) for g723_16_decoder(). * private.h New file containing prototypes and tyepdefs private to G72x code. libsndfile-1.0.28/src/G72x/g72x_priv.h0000644000175000017500000001051412677561544014176 00000000000000/* * This source code is a product of Sun Microsystems, Inc. and is provided * for unrestricted use.

This fixed a compile problem on MacOSX. 2002-05-10 Erik de Castro Lopo * *.[ch] Removed all pre-ANSI prototype kludges. Removed proto.h and unproto.h. Started work on making GSM 6.10 files seekable. Currently they are not. * code.c private.h Function Gsm_Coder () used a statically defined array. This was obviously not re-entrant so moved it to struct gsm_state. 2001-09-16 Erik de Castro Lopo * code.c Added #includes for string.h and stdlib.h. 2000-10-27 Erik de Castro Lopo * config.h Removed some commented out #defines (ie //*efine) which were causing problems on the Sun cc compiler. 2000-02-29 Erik de Castro Lopo * private.h Added #defines to emulate normal compile time options. 2000-02-28 Erik de Castro Lopo * everthing Created this directory and copied files from libgsm. http://kbs.cs.tu-berlin.de/~jutta/toast.html libsndfile-1.0.28/src/GSM610/gsm610_priv.h0000644000175000017500000002053412677561544014555 00000000000000/* * Copyright 1992 by Jutta Degener and Carsten Bormann, Technische * Universitaet Berlin.

The currently defined flags format is: 0000psse where 0 = reserved, must be 0 p = 1-bit field "partial frame" flag indicating 32-bit frame length follows this byte ss = 2-bit field indicating "number of shift-off bytes ignored by compression" e = 1-bit field indicating "escape" The "partial frame" flag means that the following segment is not equal to the frame length specified in the out-of-band decoder configuration. This allows the decoder to deal with end-of-file partial segments without incurring the 32-bit overhead for each segment. The "shift-off" field indicates the number of bytes at the bottom of the word that were passed through uncompressed. The reason for this is that the entropy inherent in the LS bytes of >= 24-bit words quite often means that the frame would have to be "escaped" b/c the compressed size would be >= the uncompressed size. However, by shifting the input values down and running the remaining bits through the normal compression algorithm, a net win can be achieved. If this field is non-zero, it means that the shifted-off bytes follow after the parameter section of the header and before the compressed bitstream. Note that doing this also allows us to use matrixing on 32-bit inputs after one or more bytes are shifted off the bottom which helps the eventual compression ratio. For stereo channels, the shifted off bytes are interleaved. The "escape" flag means that this segment was not compressed b/c the compressed size would be >= uncompressed size. In that case, the audio data was passed through uncompressed after the header. The other header parameter bytes will not be sent. PARAMETERS ---------- If the segment is not a partial or escape segment, the total header size (in bytes) is given exactly by: 4 + (2 + 2 * numU) (mono mode) 4 + (2 + 2 * numV) + (2 + 2 * numV) (stereo mode) where the ALAC filter-lengths numU, numV are bounded by a constant (in the current source, numU, numV <= NUMCOEPAIRS), and this forces an absolute upper bound on header size. Each segment-decode process loads up these bytes from the front of the local stream, in the above order, then follows with the entropy-encoded bits for the given segment. To generalize middle-side, there are various mixing modes including middle-side, each lossless, as embodied in the mix () and unmix () functions. These functions exploit a generalized middle-side transformation: u := [(rL + (m-r)R)/m] ; v := L - R ; where [ ] denotes integer floor. The (lossless) inverse is L = u + v - [rV/m] ; R = L - v ; In the segment header, m and r are encoded in mixBits and mixRes. Classical "middle-side" is obtained with m = 2, r = 1, but now we have more generalized mixes.

You can embed shell variables for delayed # expansion at the time the message is displayed, but you will need to # quote other shell meta-characters carefully to prevent them being # expanded when the contents are evaled. usage='$progpath [OPTION]...' # Short help message in response to '-h' and '--help'. Add to this or # override it after sourcing this library to reflect the full set of # options your script accepts. usage_message="\ --debug enable verbose shell tracing -W, --warnings=CATEGORY report the warnings falling in CATEGORY [all] -v, --verbose verbosely report processing --version print version information and exit -h, --help print short or long help message and exit " # Additional text appended to 'usage_message' in response to '--help'. long_help_message=" Warning categories include: 'all' show all warnings 'none' turn off all the warnings 'error' warnings are treated as fatal errors" # Help message printed before fatal option parsing errors. fatal_help="Try '\$progname --help' for more information." ## ------------------------- ## ## Hook function management. ## ## ------------------------- ## # This section contains functions for adding, removing, and running hooks # to the main code.

The src/ directory contains the source code for library itself. The doc/ directory contains the libsndfile documentation. The examples/ directory contains examples of how to write code using libsndfile. The tests/ directory contains programs which link against libsndfile and test its functionality. The src/GSM610 directory contains code written by Jutta Degener and Carsten Bormann. Their original code can be found at : http://kbs.cs.tu-berlin.de/~jutta/toast.html The src/G72x directory contains code written and released by Sun Microsystems under a suitably free license. The src/ALAC directory contains code written and released by Apple Inc and released under the Apache license. LINUX ----- Whereever possible, you should use the packages supplied by your Linux distribution. If you really do need to compile from source it should be as easy as: ./configure make make install Since libsndfile optionally links against libFLAC, libogg and libvorbis, you will need to install appropriate versions of these libraries before running configure as above. UNIX ---- Compile as for Linux. Win32/Win64 ----------- The default Windows compilers are nowhere near compliant with the 1999 ISO C Standard and hence not able to compile libsndfile.

When reading short or int data from a file containing float data, and setting SFC_SET_SCALE_FLOAT_INT_READ to SF_TRUE would fail 3, 5, 7 and other channels counts. Problem was that psf_calc_signal_max() was not calculating the signal max correctly. Calculation of the signal max was failing because it was trying to read a sample count that was not an integer multiple of the channel count. * tests/channel_test.c tests/Makefile.am tests/test_wrapper.sh.in Add test for the above. 2012-09-25 Erik de Castro Lopo * src/sndfile.hh Added a constructor to allow the use of SF_VIRTUAL_IO.

Fixes github issue #4 reported by Charles Van Winkle. * src/sfconfig.h src/sfendian.h Fix for MinGW cross compiling. Use '#if (defined __*66__)' instead of '#if __*86__' because the MinGW header use '#ifdef __x86_64__'. 2012-03-10 Erik de Castro Lopo * src/ALAC/ src/alac.c Unify the interface between libsndfile and Apple ALAC codec. Regardless of file bit width samples are now passed between the two as int32_t that are justified towards the most significant bit. Without this modification, 16 conversion functions would have been needed between the libsndfile (short, int, float, double) types and the ALAC types (16, 20, 24 and 32 bit). With this mod, only 4 are needed. * tests/floating_point_test.tpl tests/write_read_test.(def|tpl) Add tests for 20 and 24 bit ALAC/CAF files. * src/command.c Add ALAC/CAF to the SFC_GET_FORMAT_* commands.

The copyyright to this code is owned by Apple who have released it under an Apache style license. A few small modifications were made to allow this to be integrated into libsndfile but unfortunately the history of those changes were lost because they were developed in a Bzr tree and during that time libsndfile moved to Git. * src/alac.c src/caf.c src/common.[ch] src/Makefile.am src/sndfile.h.in src/sndfile.c Hook new ALAC codec in. * programs/sndfile-convert.c Add support for alac codec. * tests/write_read_test.tpl Expand tests to cover ALAC. 2012-03-02 Erik de Castro Lopo * src/aiff.c src/wav.c Fix a couple of regressions from version 1.0.25. 2012-03-01 Erik de Castro Lopo * src/strings.c Minor refactoring. Make sure that the memory allocation size if always > 0 to avoid undefined behaviour. 2012-02-29 Erik de Castro Lopo * src/chunk.c Fix buffer overrun introduced in recently added chunk logging. This chunk logging has not yet made it to a libsndfile release version. Thanks to Olivier Tristan for providing an example file. * src/wav.c Fix handling of odd sized chunks which was causing the parser to lose some chunks. Thanks to Olivier Tristan for providing an example file. 2012-02-26 Erik de Castro Lopo * tests/util.tpl Used gnu_printf format checking with mingw-w64 compiler. * tests/header_test.tpl Printf format fixes. 2012-02-25 Erik de Castro Lopo * M4/extra_pkg.m4 Update PKG_CHECK_MOD_VERSION macro to add an AC_TRY_LINK step. This fix allows the configure process to catch attempts to link incompatible libraries. For example, linking 32 bit version of eg libFLAC to a 64 bit version of libsndfile will now fail. Similarly, when cross compiling libsndfile from Linux to Windows linking the Linux versions of a library to the Windows version of libsndfile will now also fail. * src/sndfile.h.in src/sndfile.c src/common.h src/create_symbols_file.py Add API function sf_current_byterate(). * src/dwvw.c src/flac.c src/ogg_vorbis.c src/sds.c Add codec specific handlers for current byterate. * tests/floating_point_test.tpl Add initial test for sf_current_byterate(). 2012-02-24 Erik de Castro Lopo * src/common.[ch] Add function psf_decode_frame_count(). * src/dwvw.c Fix a termnation bug that caused the decoder to go into an infinite loop. 2012-02-24 Erik de Castro Lopo * src/wav.c Fix a regression in the WAV header parser.

Also add support for writing Win32 .def files. The Python script generates Symbols.linux, Symbols.darwin and libsndfile.def (Win32 version). These files get shipped with the tarball so there should not be necessary to run the Python script when building the code from the tarball. * configure.ac src/Makefile.am Win32/Makefile.am Hook new Python script into the build system. 2004-02-25 Erik de Castro Lopo * src/configure.ac Add --enable-gcc-werror option and move GCC specific stuff down. 2004-02-24 Erik de Castro Lopo * acinclude.m4 configure.ac Fix clip mode detection (tested in one of HP's testdrive Itanium II boxes). * src/file_io.c Added check for sizeof (off_t) != sizeof (sf_count_t) to prevent recurrence of missing large file support on Linux and Solaris. 2004-02-19 Erik de Castro Lopo * examples/sndfile-play.c Fix a MacOSX specific bug which was caused by a space being inserted in the middle of a file name. * configure.ac src/Makefile.am examples/Makefile.am Fix a couple of MacOSX build issues. 2004-02-17 Erik de Castro Lopo * doc/command.html Document SFC_SET_CLIPPING and SFC_GET_CLIPPING. 2004-02-14 Erik de Castro Lopo * doc/*.html Applied patch from Frank Neumann (author of lakai) which fixes many minor typos in documentation.

This should work but doesn't and I'm not sure why. * Make.bat Win32/Makefile.msvc Updates. 2004-01-07 Erik de Castro Lopo * src/common.h Changed logindex, headindex and headend files of SF_PRIVATE from unsigned int to int to prevent weird arithmetic bugs. * src/common.c src/aiff.c src/wav.c src/w64.c Fixed compiler warnings resulting from above change. 2004-01-06 Erik de Castro Lopo * src/common.c Fixed a bug in header reader for some files with data after the sample data. 2003-12-29 Erik de Castro Lopo * tests/lossy_comp_test.c tests/Makefile.am Add tests for AIFF/IMA files. 2003-12-26 Erik de Castro Lopo * src/macbinary3.c src/macos.c Two new files required for handling SD2 files. * src/common.h Add prototypes for functions in above two files. * src/Makefile.am Hook new files into build system. 2003-12-21 Erik de Castro Lopo * configure.ac Add checks for mmap() and getpagesize() which might be used at some time for faster file reads. Add detection of MacOSX. 2003-12-13 Erik de Castro Lopo * doc/FAQ.html Minor mods to pkg-config section. 2003-12-12 Erik de Castro Lopo * src/create_symbols_file.sh Andre Pang (also known as Ozone) pointed out that on MacOSX, all non static symbols are exported causing troubles when trying to link libsndfile with another library which has any of the same symbols. He fixed this by supplying the MacOSX linker with a file containing all the public symbols so that only they would be exported and then supplied a patch for libsndfile. This wasn't quite ideal, because I would have to maintain two (3 if you include Win32) separate files containing the exported symbols. A better solution was to create this script which can generate a Symbols file for Linux, MacoSX and any other OS that supports minimising the number of exported symbols. * configure.ac src/Makefile.am Hook the new script into the build process. 2003-12-10 Erik de Castro Lopo * doc/index.html Added comments about Steve Dekorte's SoundConverter scam. 2003-12-07 Erik de Castro Lopo * src/file_io.c Axel Röbel pointed out that on Mac OSX a pipe is not considered a fifo (S_ISFIFO (st.st_mode) is false) but a socket (S_ISSOCK (st.st_mode) is true). The test has therefore been changed to is S_ISREG and anything which which does not return true for S_ISREG is considered a pipe. 2003-11-25 Erik de Castro Lopo * tests/misc_test.c Fix update_header_test to pass SDS. * src/sds.c More minor fixes. * tests/floating_point_test.c Add test for SDS files. * src/command.c Add SDS to major_formats array. 2003-11-24 Erik de Castro Lopo * tests/write_read_test.tpl tests/misc_test.c Add tests for SDS files. * src/sds.c Fix a bug in header update code. 2003-11-23 Erik de Castro Lopo * src/sds.c Get file write working. * src/paf.c Fix a potential bug in paf24_seek(). 2003-11-04 Erik de Castro Lopo * doc/FAQ.html Add Q/A about u-law encoded WAV files. * Win32/*.h Updated so it compiles on Win32. 2003-11-03 Erik de Castro Lopo * examples/sndfile-convert.c Add -alaw and -ulaw command line arguments. * configure.ac Add library versioning comments. Add arguments to AC_INIT. 2003-10-28 Erik de Castro Lopo * src/file_io.c Ross Bencina has contributed code to replace all of the (mostly broken) Win32 POSIX emulation calls with calls the native Win32 file I/O API. This code still needs testing but is likely to be a huge improvemnt of support for Win32. Thanks Ross. 2003-10-27 Erik de Castro Lopo * src/dwvw.c Removed filedes field from the DWVW_PRIVATE struct. * src/file_io.c Change psf_fopen() so it returns psf->error instead of the file descriptor. Add new functions psf_set_stdio() and psf_set_file(). * src/sndfile.c Change these to work with changed psf_fopen() return value. Remove all uses of psf->filedes from sndfile, making it easier to slot native Win32 API file handling functions. * src/test_file_io.c Minor changes to make it compile with new file_io.c stuff. 2003-10-26 Erik de Castro Lopo * src/gsm610.h Rename a variable from true to true_flag. As Ross Bencina points out, true is defined in the C99 header . * src/file_io.c If fstat() fails, return SF_TRUE instead of -1 (Ross Bencina). 2003-10-09 Erik de Castro Lopo * src/common.h Increase the size of SF_BUFFER_LEN and SF_HEADER_LEN. * src/sndfile.c Fix sf_read/write_raw which were dividing by psf->bytwidth and psf->blockwidth which can both be zero. * examples/sndfile-info.c Increase size of BUFFER_LEN. 2003-09-21 Erik de Castro Lopo * configure.ac Add checks for and ssize_t. Other Win32/MinGW checks. * src/aiff.c src/au_g72x.c src/file_io.c src/gsm610.c src/interleave.c src/paf.c src/sds.c src/svx.c src/voc.c src/w64.c src/wav.c src/xi.c Fix compiler warnings. 2003-09-20 Erik de Castro Lopo * tests/scale_clip_test.tpl Add definition of M_PI if needed. 2003-09-19 Erik de Castro Lopo * configure.ac Detect if S_IRGRP is declared in . * src/file_io.c tests/*.tpl tests/*.c More fixes for Win32/MSVC++ and MinGW.

Added verbose testing mode. * src/common.h src/sndfile.c Added an embedded AU specific error code and message. * src/wav.c Added patch from Conrad Parker which filled in a little more information about ACIDized WAV files. 2003-04-30 Erik de Castro Lopo * src/file_io.c Fixed Win32 version of psf_fseek() which was calling psf_get_filelen() which was in turn calling psf_fseek() which in the end blew the stack. Now of course this would have been easy to find on Linux, but this blow up was happening in kernel32.dll and the fscking MSVC++ debugger couldn't figure out what call caused this (it couldn't even tell me the stack had overflowed) and was absolutley useless for this debugging exercise. On top of that, the reason I got into this mess was that windoze doesn't have a working fstat() function which can return file lengths > 2 Gig. It HAS a fscking _fstati64() but the file length value is only updated AFTER the bloody file is closed. That makes it completely useless. How the hell do people stand working on this crap excuse of an OS? 2003-04-29 Erik de Castro Lopo * Win32/unistd.h src/file_io.c Moved definitions of S_IGRP etc from file_io.c to unistd.h so that these can be used in the test programs. * Win32/libsndfile.def Added sf_open_fd. * Win32/sndfile.h Updated to match src/sndfile.h.in. * Win32/Makefile.msvc Added dither.c and htk.c to libsndfile.dll target. 2003-04-28 Erik de Castro Lopo * src/file_io.c First attempt at getting the Win32 versions of the these functions working. They still need to be tested. 2003-04-27 Erik de Castro Lopo * src/strings.c Found and fixed a bug which was causing psf_store_string() to fail on Motorola 68k processors. Many thanks to Joshua Haberman (Debian maintainer of libsndfile) for compiling and running debug code to help me debug the problem. 2003-04-26 Erik de Castro Lopo * src/sndfile.c src/file_io.c src/wav.c src/aiff.c Much hacking to get reading and writing of embedded files working (ie sound files at a non-zero files offset). * doc/embedded_files.html First pass atempt at documenting reading/writing embedded files. 2003-04-21 Erik de Castro Lopo * doc/FAQ.html Updated answer to "Why doesn't libsndfile do interleaving/de-interleaving?" 2003-04-19 Erik de Castro Lopo * src/wav.c src/aiff.c Fix retrieving and storing of string data from files. Need to be careful about using psf->buffer for strings. 2003-04-18 Erik de Castro Lopo * src/file_io.c Fix psf_fseek() for seeks withing embedded files. 2003-04-15 Erik de Castro Lopo * src/sndfile.h.in Changed the definition of SNDFILE slightly to produce warnings when it isn't used correctly. This should have zero affect in code which uses the SNDFILE type correctly. * src/sndfile.c Fixed a few compiler warnings cause by the changes to the SNDFILE type. 2003-04-12 Erik de Castro Lopo * doc/FAQ.html Added question and answer to the question "How about adding the ability to write/read sound files to/from memory buffers?". 2003-04-08 Erik de Castro Lopo * tests/write_read_test.tpl Removed un-needed enums declaring TRUE and FALSE and replaced usage of these with SF_TRUE and SF_FALSE. * tests/multi_file_test.c New test program to test sf_open_fd() on files containing data other than a single sound file. 2003-04-06 Erik de Castro Lopo * src/file_io.c When creating files, set the readable by others flag. This still allows further restrictions to be enforced by use of the user's umask. Fix suggested by Eric Lyon. 2003-04-05 Erik de Castro Lopo * src/sndfile.h.in src/sndfile.c Changed sf_open_fd(). Dropped offset parameter and added a close_desc parameter. If close desc is TRUE, the file descritpor passed into the library will be closed when sf_close() is called. * tests/utils.tpl Modified call to sf_open_fd() to set close_desc parameter to SF_TRUE. 2003-04-04 Erik de Castro Lopo * tests/write_read_test.tpl Add a string (using sf_set_string() function) before and after data section of all files. This will make sure that if string data can be added, it doesn't overwrite real audio data. 2003-04-02 Erik de Castro Lopo * src/sndfile.c Started work on supporting a non-zero offset parameter for sf_open_fd (). * src/.c Removed many uses of psf_fseek (SEEK_END) which to allow for future use of sf_open_fd() with non-zero offset. Associated refactoring. * src/aiff.c Implemented functionality required to get sf_get_string() and sf_set_string() working for AIFF files. 2003-04-01 Erik de Castro Lopo * tests/utils.tpl Modified test_open_file_or_die() to alternately use sf_open() and sf_open_fd(). * src/svx.c Fixed a bug which occurred when openning an existing file for read/write using sf_open_fd(). In this case, the existing NAME chunk needs to be read into psf->filename. Fixed printing of sf_count_t types to logbuffer. 2003-03-31 Erik de Castro Lopo * src/sndfile.h.in Added prototype for new function sf_open_fd(). * src/sndfile.c Moved most of the code in sf_open() to a new function psf_open_file(). Created new function sf_open_fd() which also uses psf_open_file() but does not currently support the offset parameter. * doc/api.html Document sf_open_fd(). 2003-03-09 Erik de Castro Lopo * src/sndfile.c Fixed a memory leak reported by Evgeny Karpov. Memory leak only occurred when an attempt was made to read and the open() call fails. 2003-03-08 Erik de Castro Lopo * tests/open_fail_test.c New test program to check for memory leaks when sf_open fails on a valid file. Currently this must be run manually under valgrid. * tests/Makefile.am Hook new test program into build. 2003-03-03 Erik de Castro Lopo * Octave/sndfile_save.m Octave/sndfile_play.m Added a -mat-binary option to the octave save command to force the output to binary mode even if the user has set ascii data as the default. Found by Christopher Moore. 2003-02-27 Erik de Castro Lopo * doc/dither.html New file which will document the interface which allows the addition of audio dither when sample word sizes are being reduced. * src/dither.c More work. 2003-02-26 Erik de Castro Lopo * tests/misc_test.c In update_header_test(), make HTK files a special case. * doc/index.html Added HTK to the feature matrix. 2003-02-25 Erik de Castro Lopo * src/htk.c New file for reading/writing HMM Tool Kit files. * src/sndfile.h.in src/sndfile.c src/command.c src/Makefile.am Hook in htk.c * tests/write_read_test.tpl tests/misc_test.c tests/Makefile.am Add tests for HTK files. 2003-02-22 Erik de Castro Lopo * src/wav.c Fixed a bug where the LIST chunk length was being written incorrectly. * tests/string_test.c Added call to check_log_buffer(). Minor cleanups. 2003-02-10 Erik de Castro Lopo * src/wav_w64.h Applied patch from Antoine Mathys to add extra WAV format definitions and a G72x_ADPCM_WAV_FMT struct definition. * src/wav_w64.c Applied patch from Antoine Mathys which converts wav_w64_format_str() from one huge inefficient switch statement to a binary search. * tests/string_test.c Dump log buffer if tests fail. 2003-02-07 Erik de Castro Lopo * tests/string_test.c David Viens supplied some modifications to this file which showed up a bug when using sf_set_string() and the sf_writef_float() functions. * src/sndfile.c Fixed the above bug. 2003-02-06 Erik de Castro Lopo * doc/FAQ.html Added Q and A on how to detect libsndfile in configure.in (at the suggestion of Davy Durham). 2003-02-05 Erik de Castro Lopo * src/sndfile.h.in Add enums and typedefs for dither. Deprecate SFC_SET_ADD_DITHER_ON_WRITE and SFC_SET_ADD_DITHER_ON_READ, to be replaced with SFC_SET_DITHER_ON_WRITE and SFC_SET_DITHER_ON_READ which will allow different dither algorithms to be enabled. Added SFC_GET_DITHER_INFO_COUNT and SFC_GET_DITHER_INFO. * src/sndfile.h.in src/Version_script.in Win32/libsndfile.def. Added public sf_dither_*() functions. * src/sndfile.c Implement commands above. * src/dither.c More work. Framework and external hooks into dither algorithms complete. 2003-02-03 Erik de Castro Lopo * doc/version-1.html libsndfile_version_convert.py Remove redundant files. * doc/index.html doc/api.html Remove links to version-1.html. * src/dither.c New file to allow the addition of audio dither on input and output. * src/common.h Add prototype for dither_init() function. * Makefile.am doc/Makefile.am Changes for added and removed files. 2003-02-02 Erik de Castro Lopo * Win32/Makefile.msvc Changes to force example binaries to be placed in the top level directory instead of the examples/ directory.

Add string_test to build and to tests on WAV files. * doc/index.html Added XI to support matrix. 2003-01-27 Erik de Castro Lopo * src/sndfile.h.in Added prototypes for sf_get_string() and sf_set_string() and SF_STR_* enum values. * src/sndfile.c Added public interface to sf_get_string() and sf_set_string(). * src/wav.c Added code for setting and getting strings in WAV files. * tests/string_test.c New test program for sf_get_string() and sf_set_string() functionality. * tests/Makefile.am Hook new test program into build and test framework. 2003-01-26 Erik de Castro Lopo * src/common.h Added fields to SF_PRIVATE for string data needed to implement sf_get_string() and sf_set_string(). * src/strings.c New file for storing and retrieving strings to/from files. * src/Makefile.am Added strings.c to build. 2003-01-25 Erik de Castro Lopo * src/xi.c Read seems to be working so looking at write. * src/sndfile.h.in Added SF_FORMAT_XI, SF_FORMAT_DPCM_8 and SF_FORMAT_DPCM_16 enum values. * tests/floating_point_test.c tests/lossy_comp_test.c tests/Makefile.am Added test for 8 and 16 bit XI format files. 2003-01-24 Erik de Castro Lopo * doc/index.html Added a non-lawyer readable summary of the licensing provisions as suggested by Steve Dekorte. 2003-01-23 Erik de Castro Lopo * src/wav.c Fixed a compiler warning found by Alexander Lerch. 2003-01-18 Erik de Castro Lopo * configure.ac Fixed the multiple linking of libm. 2003-01-17 Erik de Castro Lopo * Win32/Makefile.mcvs Added comments on the correct way to set up the MSVCDir environment variable. * doc/win32.html Add on how to set up the MSVCDir environment variable. 2003-01-15 Erik de Castro Lopo * examples/sndfile-play.c examples/sndfile-info.c When run on Win32 without any command line parameters print a message and then sleep for 5 seconds. This means the when somebody double clicks on these programs in explorer the user will actually see the message. 2003-01-14 Erik de Castro Lopo * tests/misc_test.c Bypass permission test if running as root because root is allowed to open a readonly file for write. 2003-01-08 Erik de Castro Lopo * Win32/Makefile.msvc Added pvf.c and xi.c source files to project. * src/sndfile.h Updated for PVF files. 2003-01-07 Erik de Castro Lopo * src/sndfile.c Modified validate_sfinfo() to force samplerate, channels and sections to be >= 1. In format_from_extension() replaced calls to does_extension_match() with strcmp(). * src/xi.c More work. 2003-01-06 Erik de Castro Lopo * doc/Makefile.am Added octave.html which had been left out. Found by Jan Weil. 2003-01-05 Erik de Castro Lopo * src/pvf.c src/common.h src/sndfile.c Fixed error handling for PVF files. * src/xi.c New file for handling Fasttracker 2 Extended Instrument files. Not working yet and included when configured with --enable-experimental. * src/sndfile.c src/common.h Hooked in new file xi.c. 2002-12-30 Erik de Castro Lopo * src/rx2.c Added a patch from Marek Peteraj which sheds a little more light on the slices within an RX2 file. Still need to find out data encoding. 2002-12-20 Erik de Castro Lopo * src/wav.c Started work on decoding 'acid' and 'strc' chunks. 2002-12-14 Erik de Castro Lopo * tests/peak_check_test.c Minor cleanup. 2002-12-12 Erik de Castro Lopo * tests/write_read_test.tpl Added check to make sure no error was generated when an attempt was made to read past the end of the file. 2002-12-11 Erik de Castro Lopo * doc/lists.html Added "mailto" links for all three lists. * src/pvf.c New file for Portable Voice Format files. * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am Added hooks for SF_FORMAT_PVF format files. * tests/write_read_test.tpl tests/std*.c Add tests for SF_FORMAT_PVF. * doc/index.html Add PVF to the compatibility matrix. * src/pcm.c src/alaw.c src/ulaw.c src/float32.c src/double64.c Previously, attempts to read beyond the end of a file would set psf->error to SFE_SHORT_ERROR. This behaviour diverged from the behaviour of the POSIX read() call but has now been fixed. Attempts to read beyond the end of the file will return a short read count but will not longer set any error. 2002-12-09 Erik de Castro Lopo * src/sndfile.c Add more sanity checking when opening a RAW file for read. When format is not RAW, zero out all members of the SF_INFO struct. * tests/raw_test.c Add bad_raw_test() to check for above problem. * tests/stdin_test.c examples/sndfile-info.c Set the format field of the SF_INFO struct to zero before calling sf_open(). * doc/api.html Add information about the need to set the format field of the SF_INFO struct to zero when opening non-RAW files for read. * configure.ac Removed use of conversion script on Solaris. Not all Solaris versions support it. * doc/lists.html New file containg details of the mailing lists. * doc/index.html Add a link to the above new file. 2002-12-04 Erik de Castro Lopo * tests/dft_cmp.c Fixed a SIGFPE on Alpha caused by a log10 (0.0). Thanks to Joshua Haberman for providing the gdb traceback. 2002-11-28 Erik de Castro Lopo * src/wav.c Added more capabilities to 'smpl' chunk parser. * src/sndfile.c Fixed some (not all) possible problems found with Flawfinder. 2002-11-24 Erik de Castro Lopo * src/sndfile.c Fixed a bug in sf_seek(). This bug could only occur when an attempt was made to read beyond the end and then sf_seek() was called with a whence parameter of SEEK_CUR. * src/file_io.c Win32's _fstati64() does not work, it returns BS. Re-implemented psf_get_filelen() in terms of psf_fseek(). * tests/write_read_test.tpl Add a test to detect above bug. * src/float_cast.h Modification to prevent compiler warnings on Mac OS X. * src/file_io.c Fixes for windows (what a f**ked OS). 2002-11-08 Erik de Castro Lopo * configure.ac Disable use of native lrint()/lrintf() on Mac OSX. These functions exist on Mac OSX 10.2 but not on 10.1. Forcing the use of the versions in src/float_cast.h means that a library compiled on 10.2 will still work on 10.1. 2002-11-06 Erik de Castro Lopo * configure.in configure.ac Renamed configure.in to configure.ac as expected by later versions of autoconf. Slight hacking of configure.ac to work with version 2.54 of autoconf. Changed to using -dumpversion instead of --version for determining GCC version numer as suggested by Anand Kumria. * src/G72x/Makefile.am Slight hacking required for operation with automake 1.6.3. 2002-11-05 Erik de Castro Lopo * src/common.c In psf_binheader_readf() changed type parameter type "b" type from size_t to int to prevent errors on IA64 CPU where sizeof (size_t) != sizeof (int). Thanks to Enrique Robledo Arnuncio for debugging this. 2002-11-04 Erik de Castro Lopo * test/command_test.tpl Changed test value so test would pass on Solaris. * src/Version_script.in Modified version numbering so that later versions of 1.0.X can replace earlier versions without recompilation. * src/vox_adpcm.c Fixed bug causing short reads. 2002-11-03 Erik de Castro Lopo * test/floating_point_test.c Code cleanup using functions from util.c. Add test for IEEE replacement floats and doubles. 2002-11-01 Erik de Castro Lopo * src/wav.c Fixed a possible divide by zero error when read the 'smpl' chunk. Thanks to Serg Repalov for the example file. * tests/pcm_test.tpl Used sf_command (SFC_TEST_IEEE_FLOAT_REPLACE) to test IEEE replacement code. Clean up pcm_double_test(). * src/float32.c src/double64.c Force use of IEEE replacement code using psf->ieee_replace is TRUE, Print message to log_buffer as well. Rename all broken_read_* and broken_write* functions to replace_read_* and replace_write_*. * tests/util.tpl Added string_in_log_buffer(). * tests/pcm_test.tpl Use string_in_log_buffer() to ensure that IEEE replacement code has been used. * configure.in Removed --enable-force-broken-float option. IEEE replacement code is now always tested. 2002-10-31 Erik de Castro Lopo * src/double64.c Implement code for read/writing IEEE doubles on platforms where the native double format is not IEEE. * src/float32.c src/common.h Remove float32_read() and float32_write(). Replace with float32_le_read(), float32_be_read(), float32_le_write() and float32_be_write() to match stuff in src/double64.c. * src/common.c Fix all usage of float32_write(). * src/sndfile.h.in Added SFC_TEST_IEEE_FLOAT_REPLACE command (testing only). * src/common.h Added SF_PRIVATE field ieee_replace. * src/sndfile.c In sf_command() set/reset psf->ieee_replace. 2002-10-26 Erik de Castro Lopo * tests/pcm_test.tpl Fixed a problem when testing with --enable-force-broken-float. The test was generating a value of negative zero and the broken float code is not able to write negative zero. Removing the negative zero fixed the test. 2002-10-25 Erik de Castro Lopo * src/file_io.c Added fix for Cygwin (suggested by Maros Michalik). 2002-10-23 Erik de Castro Lopo * src/file_io.c Improved error detection and handling. * src/file_io.c src/common.h Removed functions psf_ferror() and psf_clearerr() which were redundant after above improvements. * src/aiff.c src/svx.c src/w64.c src/wav.c Removed all use of psf_ferror() and psf_clearerr(). * src/sndfile.c Removed #include of , , and which are no longer needed. * tests/misc_test.c Added test to make sure the correct error message is returned with an existing read-only file is openned for write. 2002-10-21 Erik de Castro Lopo * doc/index.html doc/api.html Updated for OKI Dialogic ADPCM files. * src/command.c Added VOX ADPCM to sub_fomats. 2002-10-20 Erik de Castro Lopo * src/vox_adpcm.c src/Makefile.am New file for handling OKI Dialogic ADPCM files. * src/sndfile.h Add new subtype SF_FORMAT_VOX_ADPCM. * src/sndfile.c Renamed function is_au_snd_file () to format_from_extenstion () and expanded its functionality to detect headerless VOX files. * src/raw.c Added hooks for SF_FORMAT_VOX_ADPCM. * examples/sndfile-info.c Print out file duration (suggested by Conrad Parker). * libsndfile.spec.in Force installation of sndfile.pc file (found by John Thompson). * tests/Makefile.am tests/lossy_comp_test.c tests/floating_point_test.c Add tests for SF_FORMAT_VOX_ADPCM. 2002-10-18 Erik de Castro Lopo * tests/misc_test.c Add test which attempts to write to /dev/full (on Linux anyway) to check for correct handling of writing to a full filesystem. * src/sndfile.c Return correct error message if the header cannot be written because the filesystem is full. * tests/util.tpl Corrected printing of file mode in error reporting. * src/mat5.c Fixed a bug where a MAT5 file written by libsndfile could not be opened by Octave 2.1.36. 2002-10-13 Erik de Castro Lopo * src/common.h src/file_io.c All low level file I/O have been modified to be better able to report system errors resulting from calling system level open/read/write etc. * src/*.c Updated for compatibility with above changes. * examples/cooledit-fixer.c New example program which fixes badly broken file created by Syntrillium's Cooledit which are marked as containing PCM samples but actually contain floating point data. * examples/Makefile.am Hooked cooledit-fixer into the build system. 2002-10-10 Erik de Castro Lopo * doc/command.html Document SFC_GET_FORMAT_INFO. 2002-10-09 Erik de Castro Lopo * examples/wav32_aiff24.c examples/sndfile2oct.c examples/sfhexdump.c examples/sfdump.c Removed these files because they weren't interesting. * examples/sfconvert.c examples/sndfile-convert.c Renamed the first to the latter. * examples/Makefile.am Added sndfile-convert to the bin_PROGRAMS, so it is installed when the lib is installed.

This is nowhere near working yet. * src/sndfile.c Added detection of 'OggS' file marker and added call to ogg_open() to switch statement. * src/ogg.c New file. Very early start of Ogg Vorbis support. * src/wav.c Added handling of brain-damaged and broken Cooledit "32 bit 24.0 float type 1" files. These files are marked as being 24 bit WAVE_FORMAT_PCM with a block alignment of 4 times the numbers of channels but are in fact 32 bit floating point. 2002-10-02 Erik de Castro Lopo * configure.in Modified option --enable-experimental to set ENABLE_EXPERIMENTAL_CODE in config.h to either 0 or 1. * src/sndfile.c Modify sf_command (SFC_GET_LIB_VERSION) to append "-exp" to the version string if experimental code has been enabled. 2002-10-01 Erik de Castro Lopo * src/Makefile.am Added -lm to libsndfile_la_LIBADD. This means that -lm is not longer needed in the link line when linking something to libsndfile. * tests/Makefile.am examples/Makefile.am Removed -lm from all link lines. * sndfile.pc.in Removed -lm from Libs line. 2002-09-24 Erik de Castro Lopo * src/file_io.c Removed all perror() calls. * src/nist.c Removed calls to exit() function. Added check to detect NIST files dammaged from Unix CR -> Win32 CRLF conversion process. 2002-09-24 Erik de Castro Lopo * src/sndfile.h.in src/sndfile.c New function sf_strerror() which will eventually replace functions sf_perror() and sf_error_str(). Function sf_error_number() has also been changed, but this was documented as being for testing only. * doc/api.html Documented above changes. * tests/*.c examples/*.c Changed to new error functions. 2002-09-22 Erik de Castro Lopo * configure.in Detect GCC version, and print a warning message about writeable strings it GCC major version number is less than 3. 2002-09-21 Erik de Castro Lopo * src/sndfile.h.in doc/api.html Documentation fixes. 2002-09-19 Erik de Castro Lopo * src/Version_script.in src/Makefile.am configure.in Use the version script to prevent the exporting of all non public symbols.

Non-interleaved data is only supported on read. * src/Makefile.am Added src/interleave.c to build. 2002-09-03 Erik de Castro Lopo * src/double64.c src/common.h Added double64_be_read(), double64_le_read(), double64_be_write() and double64_le_write() which replace double64_read() and double64_write(). * src/common.c Cleanup of psf_binheader_readf() and add ability to read big and little endian doubles (required by mat4.c and mat5.c). Add ability for psf_binheader_writef() to write doubles to sound file headers. 2002-09-01 Erik de Castro Lopo * src/mat5.c New file for reading Matlab (tm) version 5 data files. This is also the native binary file format for version 2.1.X of GNU Octave which will be used for testing. Not complete yet. * src/mat4.c New file for reading Matlab (tm) version 4.2 data files. This is also the native binary file format for version 2.0.X of GNU Octave which will be used for testing. Not complete yet. * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am Mods to add Matlab files. * src/common.[ch] Added readf_endian field to SF_PRIVATE struct allowing endianness to remembered across calls to sf_binheader_readf().

Thanks to Stephane Letz. * src/wav.c Changed an snprintf to LSF_SNPRINTF. * doc/Makefile.am Added version-1.html. 2002-08-14 Erik de Castro Lopo * configure.in Bumped version to 1.0.rc6. * src/*.c Modified scaling of normalised floats and doubles to integers. Until now this has been done by multiplying by 0x8000 for short output, 0x80000000 for 32 bit ints and so on. Unfortunately this can cause an overflow and wrap around in the target value. All thes values have therefore been reduced to 0x7FFF, 0x7FFFFFFF and so on. The conversion from ints to normalised floats and doubles remains unchanged. This does mean that for repeated conversions normalised float -> pcm16 -> normalised float would result in a decrease in amplitude of 0x7FFF/0x8000 on every round trip. This is undesirable but less undesireable than the wrap around I am trying to avoid. * tests/floating_point_test.c Removed file hash checking because new float scaling procedure introduced above prevented the ability to crate a has on both x86 and PowerPC systems. 2002-08-13 Erik de Castro Lopo * src/txw.c Completed reading of TXW files. Seek doesn't work yet. * src/file_io.c Added a MacOS 9 replacement for ftruncate(). * MacOS/sndfile.h Added MacOS 9 header file. This should be copied into src/ to compile libsndfile for MacOS9. 2002-08-12 Erik de Castro Lopo * src/sndfile.c Fixed commands SF_SET_NORM_DOUBLE and SFC_SET_NORM_FLOAT to return their values after being set. Reported by Jussi Laako. * configure.in If autogen is not found, touch all .c and .h files in tests/. * src/common.c Added format width specifier to psf_log_printf() for %u, %d, %D and %X. * src/dwd.c Completed implementation of read only access to these files. * src/common.h src/*.c src/pcm.c Removed redundant field chars from SF_PRIVATE struct and modified pcm_init() to do without it. 2002-08-11 Erik de Castro Lopo * src/wve.c New file implementing read of Psion Alaw files. This will be a read only format. Implementation complete. * src/dwd/c Started implementation of DiamondWare Digitized files. Also read only, not complete. * src/wav.c Add parsing of 'smpl' chunk. * src/paf.c Fixed reading on un-normalized doubles and floats from 24 bit PAF files. This brings it into line with the reading of 8 bit files into un-normalized doubles which returns values in the range [-128, 127]. * src/common.c Modified psf_log_printf() to accept the %% conversion specifier to allow printing of a single '%'. * src/sds.c Read only of 16 bit samples is working. Need to build a test harness for this and other read only formats. 2002-08-10 Erik de Castro Lopo * configure.in Added --enable-experimental configure option. Removed pkg-config message at the end of the configure process. * src/sds.c src/txw.c src/rx2.c src/sd2.c Moved all the code in these files inside #if ENABLE_EXPERIMENTAL_CODE blocks and added new *_open() function for the case where experimental is not enabled. These new functions just return SFE_UNIMPLMENTED. * Win32/sndfile.h src/sndfile.h.in src/common.h Removed un-necessary #pragma pack commands. * src/file_io.c Implemented psf_ftruncate() and much other hacking for Win32. * Win32/Makefile.msvc Updated. * doc/win32.html Updated to include the copying of the sndfile.h file from the Win32/ directory to the src/ directory. * Make.bat Batch file to make compiling on Wi32 a little easier. Implements "make" and "make check". 2002-08-09 Erik de Castro Lopo * src/file_io.c Add place holder for ftruncate() on Win32 which doesn't have ftruncate(). This will need to be fixed later. * src/sndfile.h.in New file (copy of sndfile.h) with sets up @TYPEOF_SF_COUNT_T@ which will be replaced by the correct type during configure. * configure.in Modified to find a good type for TYPEOF_SF_COUNT_T. * src/aiff.c Fixed a bug when reading malformed headers. * src/common.c Set read values to zero before performing read. 2002-08-08 Erik de Castro Lopo * doc/command.html Fixed some HTML tags which were not allowing jumps to links within the page. * src/sds.c Massive hacking on this. * src/wav.c Added recognition of 'clm ' tag. 2002-08-07 Erik de Castro Lopo * doc/index.html Added beginning of a capabilities list beyond simple file formats which can be read/written. * src/aiff.c Added parsing of INST and MARK chunks of AIFF files. At the moment this data is simply recorded in the log buffer. Later it will be possible to read this data from an application using sf_command(). * src/wav.c Added parsing of 'cue ' chunk which contains loop information in WAV files. * exampes/sndfile-info.c Changed reporting of Samples to Frames. * src/wav.c src/w64.c src/aiff.c src/wav_w64.h Moved from a samples to a frames nomenclature to avoid confusion. * doc/FAQ.html What's the best format for storing temporary files? * src/sds.c New file for reading/writing Midi Sample Dump Standard files. * src/Makefile.am src/sndfile.c src/common.[ch] Added hooks for sds.c. * examples/sndfile-info.c Changed from using sf_perror() to using sf_error_str(). 2002-08-06 Erik de Castro Lopo * doc/api.html Added explanation of mode parameter for sf_open(). Added explanation of usage of SFM_* values in sf_seek(). * src/sndfile.[ch] src/command.c src/file_io.c src/common.h Implemented SFC_FILE_TRUNCATE to allow a file to be truncated. File truncation was suggested by James McCartney. * src/command.html Documented SFC_FILE_TRUNCATE. * tests/command_test.c Add tests for SFC_FILE_TRUNCATE. * src/sndfile.c Added a thrid parameter to the VALIDATE_SNDFILE_AND_ASSIGN_PSF macro to make resetting the error number optional. All uses of the macro other than in error reporting functions were changed to reset the error number. * src/pcm.c Fixed a bug were sf_read_* was logging an SFE_SHORT_READ even when no error occurred. * tests/write_read_test.tpl Added tests of internal error state. 2002-08-05 Erik de Castro Lopo * src/GSM610/private.h src/GSM610/*.c src/GSM610/Makefile.am Renamed private.h to gsm610_priv.h to prevent clash with other headers named private.h in other directories. (Probably only a problem on MacOS 9). * src/G72x/private.h src/G72x/*.c src/G72x/Makefile.am Renamed private.h to g72x_priv.h to prevent clash with other headers named private.h in other directories. (Probably only a problem on MacOS 9). * MacOS/config.h Changed values of HAVE_LRINT and HAVE_LRINTF to force use of code in float_cash.h. * src/sndfile.h Changes the name of samples field of the SF_INFO to frames. The old name had caused too much confusion and it simply had to be changed.

The Win32 PCM sample I/O API sucks. The sndfile-play program now works on Linux, MacOSX, Solaris and Win32. 2002-07-25 Erik de Castro Lopo * doc/FAQ.html New file for frequently asked questsions. 2002-07-22 Erik de Castro Lopo * doc/api.html Documentation fixes. * src/au.[ch] src/au_g72x.c src/G72x/g72x.h Add support of 40kbps G723 ADPCM encoding. * tests/lossy_comp_test.c tests/floating_point_test.c Add tests for 40kbps G723 ADPCM encoding. * doc/index.html Update support matrix. 2002-07-21 Erik de Castro Lopo * doc/command.html Documented SFC_GET_SIMPLE_FORMAT_COUNT, SFC_GET_SIMPLE_FORMAT, SFC_GET_FORMAT_* and SFC_SET_ADD_PEAK_CHUNK. * src/sndfile.c src/pcm.c Add ability to turn on and off the addition of a PEAK chunk for floating point WAV and AIFF files. * src/sndfile.[ch] src/common.h src/command.c Added sf_command SFC_CALC_MAX_ALL_CHANNELS. Implemented by Maurizio Umberto Puxeddu. * doc/command.html Docs for SFC_CALC_MAX_ALL_CHANNELS (assisted by Maurizio Umberto Puxeddu). 2002-07-18 Erik de Castro Lopo * src/sndfile.c src/gsm610.c Finalised support for GSM 6.10 AIFF files and added support for GSM 6.10 encoded RAW (header-less) files. * src/wav.c Add support for IBM_FORMAT_MULAW and IBM_FORMAT_ALAW encodings. * src/api.html Fixed more documentation bugs. 2002-07-17 Erik de Castro Lopo * src/sndfile.h src/common.h Moved some yet-to-be-implelmented values for SF_FORMAT_* from the public header file sndfile.h to the private header file common.h to avoid confusion about the actual capabilities of libsndfile. 2002-07-16 Erik de Castro Lopo * src/aiff.c src/wav.c Fixed file parsing for WAV and AIFF files containing non-audio data after the data chunk. * src/aiff.c src/sndfile.c Add support for GSM 6.10 encoded AIFF files. * tests/lossy_comp_test.c tests/Makefile.am Add tests for GSM 6.10 encoded AIFF files. * src/*.c Fix compiler warnings. 2002-07-15 Erik de Castro Lopo * tests/command_test.c For SFC_SET_NORM_* tests, change the file format from SF_FORMAT_WAV to SF_FORMAT_RAW. * src/sndfile.c Added sf_command(SFC_TEST_ADD_TRAILING_DATA) to allow testing of reading from AIFF and WAV files with non-audio data after the audio chunk. * src/common.h Add test commands SFC_TEST_WAV_ADD_INFO_CHUNK and SFC_TEST_AIFF_ADD_INST_CHUNK. When these commands are working, they will be moved to src/sndfile.h * src/aiff.c src/wav.c Begin implementation of XXXX_command() hook for sf_command(). * tests/write_read_test.tpl Added sf_command (SFC_TEST_ADD_TRAILING_DATA) to ensure above new code was working. 2002-07-13 Erik de Castro Lopo * tests/update_header_test.c Allow read sample count == write sample count - 1 to fix problems with VOC files. * tests/write_read_test.tpl tests/pcm_test.tpl Fixed some problems in the test suite discovered by using Valgrind. 2002-07-12 Erik de Castro Lopo * tests/utils.[ch] tests/*.c Renamed check_log_buffer() to check_log_buffer_or_die(). * src/sndfile.c SFC_UPDATE_HEADER_NOW and SFC_SETUPDATE_HEADER_AUTO almost finished. Works for all file formats other than VOC. 2002-07-11 Erik de Castro Lopo * src/sndfile.[ch] src/common.h Started adding functionality to allow the file header to be updated before the file is closed on files open for SFM_WRITE. This was requested by Maurizio Umberto Puxeddu who is using libsndfile for file I/O in iCSound. * tests/update_header_test.c New test program to test that the above functionality is working correctly. * tests/peak_chunk_test.c tests/floating_point_test.c Cleanups. 2002-07-10 Erik de Castro Lopo * src/sfendian.[ch] Changed length count parameters for all endswap_XXX() functions from sf_count_t (which can be 64 bit even on 32 bit architectures) to int. These functions are only called frin inside the library, are always called with integer parameters and doing the actual calculation on 64 bit values is slow in comparision to doing it on ints. * examples/sndfile-play.c More playback hacking for Win32. 2002-07-09 Erik de Castro Lopo * src/common.c In psf_log_printf(), changed %D format conversion specifier to %M (marker) and added %D specifier for printing the sf_count_t type. * src/*.c Changed all usage of psf_log_printf() with %D format conversion specifiers to use %M conversion instead. * tests/pcm_test.tpl tests/pcm_test.def New files to autogen pcm_test.c. * src/pcm.c Fixed bug in scaling floats and doubles to 24 bit PCM and vice versa. 2002-07-08 Erik de Castro Lopo * configure.in Fix setup of $ac_cv_sys_largefile_CFLAGS so that sndfile.pc gets valid values for CFLAGS. * examples/sndfile-play.c Start adding playback support for Win32. 2002-07-07 Erik de Castro Lopo * src/*.c Worked to removed compiler warnings. Extensive refactoring. * src/common.[ch] Added function psf_memset() which works like the standard C function memset but takes and sf_count_t as the length parameter. * src/sndfile.c Replaced calls to memset(0 with calls to psf_memset() as required. 2002-07-06 Erik de Castro Lopo * src/sndfile.c Added "libsndfile : " to the start of all error messages. This was suggested by Conrad Parker author of Sweep ( http://sweep.sourceforge.net/ ). * src/sfendian.[ch] Added endswap_XXXX_copy() functions. * src/pcm.c src/float32.c src/double64.c Use endswap_XXXX_copy() functions and removed dead code. Cleanups and optimisations. 2002-07-05 Erik de Castro Lopo * src/sndfile.c src/sndfile.h Gave values to all the SFC_* enum values to allow better control of the interface as commands are added and removed. Added new command SFC_SET_ADD_PEAK_CHUNK. * src/wav.c src/aiff.c Modified wav_write_header and aiff_write_header to make addition of a PEAK chunk optional, even on floating point files. * tests/benchmark.tpl Added call to sf_command(SFC_SET_ADD_PEAK_CHUNK) to turn off addition of a PEAK chunk for the benchmark where we are trying to miximize speed. * src.pcm.c Changed tribyte typedef to something more sensible. Further conversion speed ups. 2002-07-03 Erik de Castro Lopo * src/command.c In major_formats rename "Sphere NIST" to "NIST Sphere". * src/common.c src/sfendian.c Moved all endswap_XXX_array() functions to sfendian.c. These functions will be tweaked to provide maximum performance. Since maximum performance on one platform does not guarantee maximum performance on another, a small set of functions will be written and the optimal one chosen at compile time. * src/common.h src/sfendian.h Declarations of all endswap_XXX_array() functions moved to sfendian.h. * src/Makefile.am Add sfendian.c to build targets. 2002-07-01 Erik de Castro Lopo * src/pcm.c src/sfendian.h Re-coded PCM encoders and decoders to match or better the speed of libsndfile version 0.0.28. 2002-06-30 Erik de Castro Lopo * src/wav.c Add checking for WAVPACK data in standard PCM WAV file. Return error if found. This WAVPACK is *WAY* broken. It uses the same PCM WAV file header and then stores non-PCM data. * tests/benchmark.tpl Added more tests. 2002-06-29 Erik de Castro Lopo * tests/benchmark.tpl Added conditional definition of M_PI. For Win32, set WRITE_PERMS to 0777. * Win32/Makefile.msvc Added target to make generate program on Win32. * src/samplitude.c Removed handler for Samplitude RAP file format. This file type seems rarer than hens teeth and is completely undocumented. * src/common.h src/sndfile.c src/Makefile.am Win32/Makefile.msvc Removed references to sampltiude RAP format. * tests/benchmark.tpl Benchmark program now prints the libsndfile version number when run. This program was also backported to version 0 to compare results. Version 1.0.0rc2 is faster than version 0.0.28 on most conversions but slower on some. The slow ones need to be fixed before final release. 2002-06-28 Erik de Castro Lopo * tests/benchmark.def tests/benchmark.tpl New files which generate tests/benchmark.c using Autogen. Added int -> SF_FORMAT_PCM_24 test. * tests/benchmark.c Now and Autogen output file. * tests/Makefile.am Updated for above changes. 2002-06-27 Erik de Castro Lopo * tests/benchmark.c Basic benchmark program complete. Need to convert it to Autogen. * Win32/Makefile.msvc Added benchmark.exe target. 2002-06-26 Erik de Castro Lopo * examples/generate.c New program to generate a number of different output file formats from a single input file. This allows testing of the created files. * tests/benchmark.c New test program to benchmark libsndfile. Nowhere near complete yet. * examples/Makefile.am tests/Makefile.am New make rules for the two new programs. 2002-06-25 Erik de Castro Lopo * Win32/libsndfile.def Removed definition for sf_signal_max(). * src/sndfile.c Removed cruft. * doc/index.html A number of documentation bugs were fixed.

Added sanity check for proper values for CFLAGS. 2002-06-14 Erik de Castro Lopo * src/sndfile.c Code clean up in sf_open (). * Win32/Makefile.msvc Michael Fink's contributed MSVC++ makefile was hacked to bits and put back together in a new improved form. * src/file_io.c Fixes for Win32; _lseeki64() returns an invalid argument for calls like _lseeki64(fd, 0, SEEK_CUR) so need to use _telli64 (fd) instead. * src/common.h src/sndfile.c src/wav.c src/aiff.c Added SFE_LOG_OVERRUN error. Added termination for potential infinite loop when parsing file headers. * src/wav.c src/w64.c Fixed bug casuing incorrect header generation when opening file read/write. 2002-06-12 Erik de Castro Lopo * doc/api.html Improved the documentation to make it clearer that the file read method and the underlying file format are completely disconnected. Suggested by Josh Green. * doc/command.html Started correcting docs to take into account changes made to the operations of the sf_command () function. Not complete yet. * src/sndfile.c Reverted some changes which had broken the partially working SDII header parsing. Now have access to an iBook with OS X so reading and writing SDII files on all platforms should be a reality in the near future. On Mac this will involve reading the resource fork via the standard MacOS API. To move a file from Mac to another OS, the resource and data forks will need to be combined before transfer. The combined file will be read on both Mac and other OSes like any other file. 2002-06-08 Erik de Castro Lopo * ltmain.sh Applied a patch from http://fink.sourceforge.net/doc/porting/libtool.php which allows libsndfile to compile on MacOSX 10.1. This patch should not interfere with compiling on other OSes. * src/GSM610/private.h Changes to fix compile problems on MacOSX (see src/GSM610/ChangeLog). * src/float_cast.h Added MacOSX replacements for lrint() and lrintf(). 2002-06-05 Erik de Castro Lopo * src/sndfile.c Replaced the code to print the filename to the log buffer when a file is opened. This code seems to have been left out during the merge of sf_open_read() and sf_open_write() to make a single functions sf_open(). 2002-06-01 Erik de Castro Lopo * src/wav.c Fixed a bug where the WAV header parser was going into an infinite loop on a badly formed LIST chunk. File supplied by David Viens. 2002-05-25 Erik de Castro Lopo * configure.in Added a message at the end of the configuration process to warn about the need for the use of pkg-config when linking programs against version 1 of libsndfile. * doc/pkg-config.html New documentation file containing details of how to use pkg-config to retrieve settings for CFLAGS and library locations for linking files against version 1 of libsndfile. 2002-05-17 Erik de Castro Lopo * src/wav.c Fixed minor bug in handling of so-called ACIDized WAV files. 2002-05-16 Erik de Castro Lopo * Win32/libsndfile.def Win32/Makefile.msvc Two new files contributed by Michael Fink (from the winLAME project) which allows libsndfile to be built on windows in a MSDOS box by doing "nmake -f Makefile.msvc". Way cool! 2002-05-15 Erik de Castro Lopo * configure.in MacOSX is SSSOOOOOOO screwed up!!! I can't believe how hard it is to generate a tarball which will configure and compile on that platform. Joined the libtool mailing list to try and get some answers. 2002-05-13 Erik de Castro Lopo * configure.in Changed to autoconf version 2.50. MacOSX uses autoconf version 2.53 which is incompatible with with version 2.13 which had been using until now. The AC_SYS_LARGE_FILE macro distributed withe autoconf 2.50 is missing a few features so AC_SYS_EXTRA_LARGE file was defined to replace it. * configure.in Changed to automake version 1.5 to try and make a tarball which will work on MacOSX. 2002-05-12 Erik de Castro Lopo * src/wav_gsm610.c Changed name to gsm610.c. Added reading/writing of headerless files. * src/sndfile.c src/raw.c Added ability to read/write headerless (SF_FORMAT_RAW) GSM 6.10 files. 2002-05-11 Erik de Castro Lopo * tests/lossy_comp_test.c Clean up in preparation for Autogen-ing this file. * src/GSM610/*.[ch] Code cleanup and prepartion forgetting file seek working. Details in src/GSM610/ChangeLog. * sndfile.pc.in Testing complete. Is sndfile.m4 still needed? 2002-05-09 Erik de Castro Lopo * tests/write_read_test.tpl tests/rdwr_test.tpl Merged tests from these two programs into write_read_test.tpl and deleted rdwr_test.tpl. 2002-05-08 Erik de Castro Lopo * src/w64.c src/svx.c src/paf.c Fixed bugs in read/write mode. 2002-05-07 Erik de Castro Lopo * examples/Makefile.am Renamed sfplay.c to sndfile-play.c and sndfile_info.c to sndfile-info.c for consistency when these programs become part of the Debian package sndfile-programs. * sndfile.pc.in New file to replace sndfile-config.in. Libsndfile now uses the pkg-config model for providing installation parameters to dependant programs. * src/sndfile.c Cleanup of code in sf_open(). 2002-05-06 Erik de Castro Lopo * tests/utils.tpl tests/write_read_test.tpl More conversion to Autogen fixes and enchancements. * src/*.c Read/write mode is now working for 16, 24 and 32 bit PCM as well as 32 bit float and 64 bit double data. More tests still required. * src/Makefile.am Added DISTCLEANFILES target to remove config.status and config.last. * Win32/Makefile.am MacOS/Makefile.am Added DISTCLEANFILES target to remove Makefile. 2002-05-05 Erik de Castro Lopo * src/*.[ch] tests/rdwr_test.c More verifying workings of read/write mode. Fixing bugs found. * tests/utils.[ch] Made these files Autogen generated files. * tests/util.tpl tests/util.def New Autogen files to generate utils.[ch]. Moved some generic test functions into this file. Autogen is such a great tool! 2002-05-03 Erik de Castro Lopo * src/pcm.c src/float_cast.h Win32/config.h Fixed a couple of Win32 specific bugs pointed out by Michael Fink (maintainer of WinLAME) and David Viens. * tests/check_log_buffer.[ch] tests/utils.[ch] Moved check_log_buffer() to utils.[ch] and deleted old file. 2002-05-02 Erik de Castro Lopo * src/common.[ch] src/sndfile.c New function psf_default_seek() which will be the default seek function for things like PCM and floating point data. This default is set for both read and write in sf_open() but can be over-ridden by any codec during it's initialisation. 2002-05-01 Erik de Castro Lopo * src/au.c AU files use a data size value of -1 to mean unknown. Fixed au_open_read() to allow opening files like this. * tests/rdwr_test .c Added more tests. * src/sndfile.c Fixed bugs in read/write mode found due to improvements in the test program. 2002-04-30 Erik de Castro Lopo * tests/rdwr_test .c New file for testing read/write mode. 2002-04-29 Erik de Castro Lopo * m4/* Removed all m4 macros from this directory as they get concatenated to form the file aclocal.m4 anyway. * sndfile.m4 Moved this from the m4 directory to the root directory asn this is part of the distribution and is installed during "make install". 2002-04-29 Erik de Castro Lopo * src/float32.c Removed logging of peaks for all file formats other than AIFF and WAV. * tests/write_read_test.tpl tests/write_read_test.def New files which autogen uses to generate write_read_test.c. Doing it this way makes write_read_test.c far easier to maintain. Other test programs will be converted to autogen in the near future. * src/*.c Fixed a few bugs found when testing on Sparc (bug endian) Solaris. 2002-04-28 Erik de Castro Lopo * doc/*.html Fixed documention versioning. * configure.in Fixed a bug in the routines which search for Large File Support on systems which have large file support by defualt. 2002-04-27 Erik de Castro Lopo * src/*.[ch] Found and fixed an issue which can cause a bug in other software (I was porting Conrad Parker's Sweep program from version 0 of the library to version 1). When opening a file for write, the libsndfile code would set the sfinfo.samples field to a maximum value. * tests/write_read_test.c Added tests to detect the above problem. 2002-04-25 Erik de Castro Lopo * src/*.[ch] Finished base implementation of read/write mode. Much more testing still needed. * m4/largefile.m4 Macro for detecting Large File Standard capabilities. This macro was ripped out of the aclocal.m4 file of GNU tar-1.13. * configure.in Added detection of large file support. Files larger than 2 Gigabytes should now be supported on 64 bit platforms and many 32 bit platforms including Linux (2.4 kernel, glibc-2.2), *BSD, MacOS, Win32. * libsndfile_convert_version.py A Python script which attempts to autoconvert code written to use version 0 to version 1. 2002-04-24 Erik de Castro Lopo * src/*.[ch] Finished base implementation of read/write mode. Much more testing still needed. * tests/write_read_test.c Preliminary tests for read/write mode added. More needed. 2002-04-20 Erik de Castro Lopo * src/sndfile.[ch] Removed sf_open_read() and sf_open_write() functions,replacting them with sf_open() which takes an extra mode parameter (SF_OPEN_READ, SF_OPEN_WRITE, or SF_OPEN_RDWR). This new function sf_open can now be modified to allow opening a file formodification (RDWR). 2002-04-19 Erik de Castro Lopo * src/*.c Completed merging of separate xxx_open_read() and xxx_open_write() functions. All tests pass. 2002-04-18 Erik de Castro Lopo * src/au.c Massive refactoring required to merge au_open_read() with au_open_write() to create au_open(). 2002-04-17 Erik de Castro Lopo * src/*.c Started changes required to allow a sound file to be opened in read/write mode, with separate file pointers for read and write. This involves merging of encoder/decoder functions like pcm_read_init() and pcm_write_init() int a new function pcm_init() as well as doing something similar for all the file type specific functions ie aiff_open_read() and aiff_open_write() were merged to make the function aiff_open(). 2002-04-15 Erik de Castro Lopo * src/file_io.c New file containing psf_fopen(), psf_fread(), psf_fwrite(), psf_fseek() and psf_ftell() functions. These function will replace use of fopen/fread/fwrite etc and allow access to files larger than 2 gigabytes on a number of 32 bit OSes (Linux on x86, 32 bit Solaris user space apps, Win32 and MacOS). * src/*.c Replaced all instances of fopen with psf_open, fread with psd_read, fwrite with psf_write and so on. 2002-03-11 Erik de Castro Lopo * src/dwvw.c Finally fixed all known problems with 12, 16 and 24 bit DWVW encoding. * tests/floating_point_test.c Added tests for 12, 16 and 24 bit DWVW encoding. 2002-03-03 Erik de Castro Lopo * m4/endian.m4 Defines a new m4 macro AC_C_FIND_ENDIAN, for determining the endian-ness of the target CPU. It first checks for the definition of BYTE_ORDER in , then in and . If none of these work and the C compiler is not a cross compiler it compiles and runs a program to test for endian-ness. If the compiler is a cross compiler it makes a guess based on $target_cpu. * configure.in Modified to use AC_C_FIND_ENDIAN. * src/sfendian.h Simplified. 2002-02-23 Erik de Castro Lopo * tests/floating_point_test.c Tests completely rewritten using the dft_cmp function. Now able to calculate a quick guesstimate of the Signal to Noise Ratio of the encoder. 2002-02-15 Erik de Castro Lopo * tests/dft_cmp.[ch] New files containing functions for comparing pre and post lossily compressed data using a quickly hacked DFT. * tests/utils.[ch] New files containing functions for saving pre and post encoded data in a file readable by the GNU Octave package. 2002-02-13 Erik de Castro Lopo * m4/lrint.m4 m4/lrintf.m4 Fixed m4 macros to define HAVE_LRINT and HAVE_LRINTF even when the test is cached. 2002-02-12 Erik de Castro Lopo * tests/floating_point_test.c Fixed improper use of strncat (). 2002-02-11 Erik de Castro Lopo * tests/headerless_test.c New test program to test the ability to open and read a known file type as a RAW header-less file. 2002-02-07 Erik de Castro Lopo * tests/losy_comp_test.c Added a test to ensure that the data read from a file is not all zeros. * examples/sfconvert.c Added "-gsm610" encoding types. 2002-01-29 Erik de Castro Lopo * examples/sfconvert.c Added "-dwvw12", "-dwvw16" and "-dwvw24" encoding types. * tests/dwvw_test.c New file for testing DWVW encoder/decoder. 2002-01-28 Erik de Castro Lopo * src/dwvw.c Implemented writing of DWVW. 12 bit seems to work, 16 and 24 bit still broken. * src/aiff.c Improved reporting of encoding types. * src/voc.c Clean up. 2002-01-27 Erik de Castro Lopo * src/dwvw.c New file implementing lossless Delta Word Variable Width (DWVW) encoding. Reading 12 bit DWVW is now working. * src/aiff.c common.h sndfile.c Added hooks for DWVW encoded AIFF and RAW files. 2002-01-15 Erik de Castro Lopo * src/w64.c Robustify header parsing. * src/wav_w64.h Header file wav.h was renamed to wav_w64.h to signify sharing of definitions across the two file types. * src/wav.c src/w64.c src/wav_w64.c Refactoring. Modified and moved functions with a high degree of similarity between wav.c and w64.c to wav_w64.c. 2002-01-14 Erik de Castro Lopo * src/w64.c Completed work on getting read and write working. * examples/sfplay.c Added code to scale floating point data so it plays at a reasonable volume. * tests/Makefile.am tests/write_read_test.c Added tests for W64 files. 2002-01-13 Erik de Castro Lopo * src/*.c Modded all code in file header writing routines to use psf_new_binheader_writef(). Removed psf_binheader_writef() from src/common.c. Globally replaced psf_new_binheader_writef with psf_binheader_writef. 2002-01-12 Erik de Castro Lopo * src/*.c Modded all code in file parsing routines to use psf_new_binheader_readf(). Removed psf_binheader_readf() from src/common.c. Globally replaced psf_new_binheader_readf with psf_binheader_readf. * src/common.[ch] Added new function psf_new_binheader_writef () which will soon replace psf_binheader_writef (). The new function has basically the same function as the original but has a more flexible and capable interface. It also allows the writing of 64 bit integer values for files contains 64 bit file offsets. 2002-01-11 Erik de Castro Lopo * src/formats.c src/sndfile.c src/sndfile.h Added code allowing full enumeration of supported file formats via the sf_command () interface. This feature will allow applications to avoid needing recompilation when support for new file formats are added to libsndfile. * tests/command_test.c Added test code for the above feature. * examples/list_formats.c New file. An example of the use of the supported file enumeration interface. This program lists all the major formats and for each major format the supported subformats. 2002-01-10 Erik de Castro Lopo * src/*.[ch] tests/*.c Changed command parameter of sf_command () function from a test string to an int. The valid values for the command parameter begin with SFC_ and are listed in src/sndfile.h. 2001-12-20 Erik de Castro Lopo * src/formats.c src/sndfile.c Added an way of enumerating a set of common file formats using the sf_command () interface. This interface was suggested by Dominic Mazzoni, one of the main authors of Audacity (http://audacity.sourceforge.net/). 2001-12-26 Erik de Castro Lopo * src/sndfile.c Added checking of filename parameter in sf_open_read (). Previousy, if a NULL pointer was passed the library would segfault. 2001-12-18 Erik de Castro Lopo * src/common.c src/common.h Changed the len parameter of the endswap_*_array () functions from type int to type long. * src/pcm.c Fixed a problem which 2001-12-15 Erik de Castro Lopo * src/sndfile.c Added conditional #include for EMX/gcc on OS/2. Thanks to Paul Hartman for pointing this out. * tests/lossy_comp_test.c tests/floating_point_test.c Added definitions for M_PI for when it isn't defined in . 2001-11-30 Erik de Castro Lopo * src/ircam.c Re-implemented the header reader. Old version was making incorrect assumptions about the endian-ness of the file from the magic number at the start of the file. The new code looks at the integer which holds the number of channels and determines the endian-ness from that. 2001-11-30 Erik de Castro Lopo * src/aiff.c Added support for other AIFC types ('raw ', 'in32', '23ni'). Further work on IMA ADPCM encoding. 2001-11-29 Erik de Castro Lopo * src/ima_adpcm.c Renamed from wav_ima_adpcm.c. This file will soon handle IMA ADPCM encodings for both WAV and AIFF files. * src/aiff.c Started adding IMA ADPCM support. 2001-11-28 Erik de Castro Lopo * src/double.c New file for handling double precision floating point (SF_FORMAT_DOUBLE) data. * src/wav.c src/aiff.c src/au.c src/raw.c Added support for SF_FORMAT_DOUBLE data. * src/common.[ch] Addition of endswap_long_array () for endian swapping 64 bit integers. This function will work correctly on processors with 32 bit and 64 bit longs. Optimised endswap_short_array () and endswap_int_array (). * tests/pcm_test.c Added and extra check. After the first file of each type is written to disk a checksum is performed of the first 64 bytes and checked against a pre- calculated value. This will work whatever the endian-ness of the host machine. 2001-11-27 Erik de Castro Lopo * src/aiff.c Added handling of u-law, A-law encoded AIFF files. Thanks to Tom Erbe for supplying example files. * tests/lossy_comp_test.c Added tests for above. * src/common.h src/*.c Removed function typedefs from common.h and function pointer casting in all the other files. This allows the compiler to perform proper type checking. Hopefully this will prevernt problems like the sf_seek bug for OpenBSD, BeOS etc. * src/common.[ch] Added new function psf_new_binheader_readf () which will eventually replace psf_binheader_readf (). The new function has basically the same function as the original but has a more flexible and capable interface. It also allows the reading of 64 bit integer values for files contains 64 bit file offsets. 2001-11-26 Erik de Castro Lopo * src/voc.c Completed implementation of VOC file handling. Can now handle 8 and 16 bit PCM, u-law and A-law files with one or two channels. * src/write_read_test.c tests/lossy_comp_test.c Added tests for VOC files. 2001-11-22 Erik de Castro Lopo * src/float_cast.h Added inline asm version of lrint/lrintf for MacOS. Solution provided by Stephane Letz. * src/voc.c More work on this braindamaged format. The VOC files produced by SoX also have a number of inconsistencies. 2001-11-19 Erik de Castro Lopo * src/paf.c Added support for 8 bit PCM PAF files. * tests/write_read_test.c Added tests for 8 bit PAF files. 2001-11-18 Erik de Castro Lopo * tests/pcm_test.c New test program to test for correct scaling of integer values between different sized integer containers (ie short -> int). The new specs for libsndfile state that when the source and destination containers are of a different size, the most significant bit of the source value becomes the most significant bit of the destination container. * src/pcm.c src/paf.c Modified to pass the above test program. * tests/write_read_test.c tests/lossy_comp_test.c Modified to work with the new scaling rules. 2001-11-17 Erik de Castro Lopo * src/raw.c tests/write_read_test.c tests/write_read_test.c Added ability to do raw reads/writes of float, u-law and A-law files. * src/*.[ch] examples/*.[ch] tests/*.[ch] Removed dependance on pcmbitwidth field of SF_INFO struct and moved to new SF_FORMAT_* types and use of SF_ENDIAN_BIG/LITTLE/CPU. 2001-11-12 Erik de Castro Lopo * src/*.[ch] Started implmentation of major changes documented in doc/version1.html. Removed all usage of off_t which is not part of the ISO C standard. All places which were using it are now using type long which is the type of the offset parameter for the fseek function. This should fix problems on BeOS, MacOS and *BSD like systems which were failing "make check" because sizeof (long) != sizeof (off_t). -------------------------------------------------------------------------------- This is the boundary between version 1 of the library above and version 0 below. -------------------------------------------------------------------------------- 2001-11-11 Erik de Castro Lopo * examples/sfplay_beos.cpp Added BeOS version of sfplay.c. This needs to be compiled using a C++ compiler so is therefore not built by default. Thanks to Marcus Overhagen for providing this. 2001-11-10 Erik de Castro Lopo * examples/sfplay.c New example file showing how libsndfile can be used to read and play a sound file. At the moment on Linux is supported. Others will follow in the near future. 2001-11-09 Erik de Castro Lopo * src/pcm.c Fixed problem with normalisation code where a value of 1.0 could map to a value greater than MAX_SHORT or MAX_INT. Thanks to Roger Dannenberg for pointing this out. 2001-11-08 Erik de Castro Lopo * src/pcm.c Fixed scaling issue when reading/writing 8 bit files using sf_read/sf_write_short (). On read, values are scaled so that the most significant bit in the char ends up in the most significant bit of the short. On write, values are scaled so that most significant bit in the short ends up as the most significant bit in the char. 2001-11-07 Erik de Castro Lopo * src/au.c src/sndfile.c Added support for 32 bit float data in big and little endian AU files. * tests/write_read_test.c Added tests for 32 bit float data in AU files. 2001-11-06 Erik de Castro Lopo * tests/lossy_comp_test.c Finalised testing of stereo files where possible. 2001-11-05 Erik de Castro Lopo * src/wav_ms_adpcm.c Fixed bug in writing stereo MS ADPCM WAV files. Thanks to Xu Xin for pointing out this problem. 2001-10-24 Erik de Castro Lopo * src/wav_ms_adpcm.c Modified function srate2blocksize () to handle 44k1Hz stereo files. 2001-10-21 Erik de Castro Lopo * src/w64.c Added support for Sonic Foundry 64 bit WAV format. As Linux (my main development platform) does not yet support 64 bit file offsets by default, current handling of this file format treats everything as 32 bit and fails openning the file, if it finds anything that goes beyond 32 bit values. * src/sndfile.[hc] src/common.h src/Makefile.am Added hooks for W64 support. 2001-10-21 Erik de Castro Lopo * configure.in Added more warnings options to CFLAGS when the gcc compiler is detected. * src/*.[ch] tests/*.c examples/*.c Started fixing the warning messages due to the new CFLASG. * src/voc.c More work on VOC file read/writing. * src/paf.c Found that PAF files were not checking the normalisation flag when reading or writing floats and doubles. Fixed it. * tests/floating_point_test.c Added specific test for the above problem. * src/float_cast.h src/pcm.c Added a section for Win32 to define lrint () and lrintf () in the header and implement it in the pcm.c 2001-10-20 Erik de Castro Lopo * sndfile-config.in m4/sndfile.m4 These files were donated by Conrad Parker who also provided instructions on how to install them using autoconf/automake. * src/float_cast.h Fiddled around with this file some more. On Linux and other gcc supported OSes use the C99 functions lrintf() and lrint() for casting from floating point to int without incurring the huge perfromance penalty (particularly on the i386 family) caused by the regular C cast from float to int. These new C99 functions replace the FLOAT_TO_* and DOUBLE_TO_* macros which I had been playing with. * configure.in m4/lrint.m4 m4/lrintf.m4 Add detection of these functions. 2001-10-17 Erik de Castro Lopo * src/voc.c Completed code for reading VOC files containing a single audio data segment. Started implementing code to handle files with multiple VOC_SOUND_DATA segments but couldn't be bothered finishing it. Multiple segment files can have different sample rates for different sections and other nasties like silence and repeat segments. 2001-10-16 Erik de Castro Lopo * src/common.h src/*.c Removed SF_PRIVATE struct field fdata and replaced it with extra_data. * src/voc.c Further development of the read part of this woefult file format. 2001-10-04 Erik de Castro Lopo * src/float_cast.h Implemented gcc and i386 floating point to int cast macros. Standard cast will be used when not on gcc for i385. * src/pcm.c Modified all uses of FLOAT/DOUBLE_TO_INT and FLOAT/DOUBLE_TO_SHORT casts to comply with macros in float_cast.h. 2001-10-04 Erik de Castro Lopo * src/voc.c Changed the TYPE_xxx enum names to VOC_TYPE_xxx to prevent name clashes on MacOS with CodeWarrior 6.0. * MacOS/MacOS-readme.txt Updated the compile instructions. Probably still need work as I don't have access to a Mac. 2001-10-01 Erik de Castro Lopo * src/wav.c src/aiff.c common.c Changed all references to snprintf to LSF_SNPRINTF and all vsnprintf to LSF_VSNPRINTF. LSF_VSNPRINTF and LSF_VSNPRINTF are defined in common.h. * src/common.h Added checking of HAVE_SNPRINTF and HAVE_VSNPRINTF and defining LSF_VSNPRINTF and LSF_VSNPRINTF to appropriate values. * src/missing.c New file containing a minimal implementation of snprintf and vsnprintf functions named missing_snprintf and missing_vsnprintf respectively. These are only compliled into the binary if snprintf and/or vsnprintf are not available. 2001-09-29 Erik de Castro Lopo * src/ircam.c New file to handle Berkeley/IRCAM/CARL files. * src/sndfile.c src/common.h Modified for IRCAM handling. * tests/*.c Added tests for IRCAM files. 2001-09-27 Erik de Castro Lopo * src/wav.c Apparently microsoft windows (tm) doesn't like ulaw and Alaw WAV files with 20 byte format chunks (contrary to ms's own documentation). Fixed the WAV header writing code to generate smaller ms compliant ulaw and Alaw WAV files. 2001-09-17 Erik de Castro Lopo * tests/stdio_test.sh tests/stdio_test.c Shell script was rewritten as a C program due to incompatibilities of the sh shell on Linux and Solaris. 2001-09-16 Erik de Castro Lopo * tests/stdio_test.sh tests/stdout_test.c tests/stdin_test.c New test programs to verify the correct operation of reading from stdin and writing to stdout. * src/sndfile.c wav.c au.c nist.c paf.c Fixed a bugs uncovered by the new test programs above. 2001-09-15 Erik de Castro Lopo * src/sndfile.c wav.c Fixed a bug preventing reading a file from stdin. Found by T. Narita. 2001-09-12 Erik de Castro Lopo * src/common.h Fixed a problem on OpenBSD 2.9 which was causing sf_seek() to fail on IMA WAV files. Root cause was the declaration of the func_seek typedef not matching the functions it was actually being used to point to. In OpenBSD sizeof (off_t) != sizeof (int). Thanks to Heikki Korpela for allowing me to log into his OpenBSD machine to debug this problem. 2001-09-03 Erik de Castro Lopo * src/sndfile.c Implemented sf_command ("norm float"). * src/*.c Implemented handling of sf_command ("set-norm-float"). Float normalization can now be turned on and off. * tests/double_test.c Renamed to floating_point_test.c. Modified to include tests for all scaled reads and writes of floats and doubles. * src/au_g72x.c Fixed bug in normalization code found with improved floating_point_test program. * src/wav.c Added code for parsing 'INFO' and 'LIST' chunks. Will be used for extract text annotations from WAV files. * src/aiff.c Added code for parsing '(c) ' and 'ANNO' chunks. Will be used for extract text annotations from WAV files. 2001-09-02 Erik de Castro Lopo * examples/sf_info.c example/Makefile.am Renamed to sndfile_info.c. The program sndfile_info will now be installed when the library is installed. * src/float_cast.h New file defining floating point to short and int casts. These casts will eventually replace all flot and double casts to short and int. See comments at the top of the file for the reasoning. * src/*.c Changed all default float and double casts to short or int with macros defined in floatcast.h. At the moment these casts do nothing. They will be replaced with faster float to int cast operations in the near future. 2001-08-31 Erik de Castro Lopo * tests/command_test.c New file for testing sf_command () functionality. * src/sndfile.c Revisiting of error return values of some functions. Started implementing sf_command () a new function will allow on-the-fly modification of library behaviour, or instance, sample value scaling. * src/common.h Added hook for format specific sf_command () calls to SNDFILE struct. * doc/api.html Updated and errors corrected. * doc/command.html New documentation file explaining new sf_command () function. 2001-08-11 Erik de Castro Lopo * src/sndfile.c Fixed error return values from sf_read*() and sf_write*(). There were numerous instances of -1 being returned through size_t. These now all set error int the SF_PRIVATE struct and return 0. Thanks to David Viens for spotting this. 2001-08-01 Erik de Castro Lopo * src/common.c Fixed use of va_arg() calls that were causing warning messages with the latest version of gcc (thanks Maurizio Umberto Puxeddu). 2001-07-25 Erik de Castro Lopo * src/*.c src/sfendian.h Moved definition of MAKE_MARKER macro to sfendian.h 2001-07-23 Erik de Castro Lopo * src/sndfile.c Modified sf_get_lib_version () so that version string will be visible using the Unix strings command. * examples/Makefile.am examples/sfinfo.c Renamed sfinfo program and source code to sf_info. This prevents a name clash with the program included with libaudiofile. 2001-07-22 Erik de Castro Lopo * tests/read_seek_test.c tests/lossy_comp_test.c Added tests for sf_read_float () and sf_readf_float (). * src/voc.c New files for handling Creative Voice files (not complete). * src/samplitude.c New files for handling Samplitude files (not complete). 2001-07-21 Erik de Castro Lopo * src/aiff.c src/au.c src/paf.c src/svx.c src/wav.c Converted these files to using psf_binheader_readf() function. Will soon be ready to attempt to make reading writing from pipes work reliably. * src/*.[ch] Added code for sf_read_float () and sf_readf_float () methods of accessing file data. 2001-07-20 Erik de Castro Lopo * src/paf.c src/wav_gsm610.c Removed two printf()s which had escaped notice for some time (thanks Sigbjørn Skjæret). 2001-07-19 Erik de Castro Lopo * src/wav_gsm610.c Fixed a bug which prevented GSM 6.10 encoded WAV files generated by libsndfile from being played in Windoze (thanks klay). 2001-07-18 Erik de Castro Lopo * src/common.[ch] Implemented psf_binheader_readf() which will do for file header reading what psf_binheader_writef() did for writing headers. Will eventually allow libsndfile to read and write from pipes, including named pipes. 2001-07-16 Erik de Castro Lopo * MacOS/config.h Win32/config.h Attempted to bring these two files uptodate with src/config.h. As I don't have access to either of these systems support for them may be completely broken. 2001-06-18 Erik de Castro Lopo * src/float32.c Fixed bug for big endian processors that can't read 32 bit IEEE floats. Now tested on Intel x86 and UltraSparc processors. 2001-06-13 Erik de Castro Lopo * src/aiff.c Modified to allow REX files (from Propellorhead's Recycle and Reason programs) to be read. REX files are basically an AIFF file with slightly unusual sequence of chunks (AIFF files are supposed to allow any sequence) and some extra application specific information. Not yet able to write a REX file as the details of the application specific data is unknown. 2001-06-12 Erik de Castro Lopo * src/wav.c Fixed endian bug when reading PEAK chunk on big endian machines. * src/common.c Fixed endian bug when reading PEAK chunk on big endian machines with --enable-force-broken-float configure option. Fix psf_binheader_writef for (FORCE_BROKEN_FLOAT ||______) 2001-06-07 Erik de Castro Lopo * configure.in src/config.h.in Removed old CAN_READ_WRITE_x86_IEEE configure variable now that float capabilities are detected at run time. Added FORCE_BROKEN_FLOAT to allow testing of broken float code on machines where the processor can in fact handle floats correctly. * src/float32.c Rejigged code reading and writing of floats on broken processors. * m4/ Removed this directory and all its files as they are no longer needed. 2001-06-05 Erik de Castro Lopo * tests/peak_chunk_test.c New test to validate reading and writing of peak chunk. * examples/sfconvert Added -float32 option. * src/*.c Changed all error return values to negative values (ie the negative of what they were). * src/sndfile.c tests/error_test.c Modified to take account of the previous change. 2001-06-04 Erik de Castro Lopo * src/float32.c File renamed from wav_float.c and renamed function to something more general. Added runtime detection of floating point capabilities. Added recording of peaks during write for generation of PEAK chunk. * src/wav.c src/aiff.c Added handing for PEAK chunk for floating point files. PEAK is read when the file headers are read and generated when the file is closed. Logic is in place for adding PEAK chunk to end of file when writing to a pipe (reading and writing from/to pipe to be implemented soon). * src/sndfile.c Modified sf_signal_max () to use PEAK values if present. 2001-06-03 Erik de Castro Lopo * src/*.c Added pcm_read_init () and pcm_write_init () to src/pcm.c and removed all other calls to functions in this file from the filetype specific files. * src/*.c Added alaw_read_init (), alaw_write_int (), ulaw_read_init () and ulaw_write_init () and removed all other calls to functions in alaw.c and ulaw.c from the filetype specific files. * tests/write_read_test.c Added tests to validate sf_seek () on all file types. * src/raw.c Implemented raw_seek () function to fix a bug where sf_seek (file, 0, SEEK_SET) on a RAW file failed. * src/paf.c Fixed a bug in paf24_seek () found due to added seeks tests in tests/write_read_test.c 2001-06-01 Erik de Castro Lopo * tests/read_seek_test.c Fixed a couple of broken binary files. * src/aiff.c src/wav.c Added handling of PEAK chunks on file read. 2001-05-31 Erik de Castro Lopo * check_libsndfile.py New file for the regression testing of libsndfile. check_libsndfile.py is a Python script which reads in a file containing filenames of audio files. Each file is checked by running the examples/sfinfo program on them and checking for error or warning messages in the libsndfile log buffer. * check_libsndfile.list This is an example list of audio files for use with check_libsndfile.py * tests/lossy_comp_test.c Changed the defined value of M_PI for math header files which don't have it. This fixed validation test failures on MetroWerks compilers. Thanks to Lord Praetor Satanus of Acheron for bringing this to my attention. 2001-05-30 Erik de Castro Lopo * src/common.[ch] Removed psf_header_setf () which was no longer required after refactoring and simplification of header writing. Added 'z' format specifier to psf_binheader_writef () for zero filling header with N bytes. Used by paf.c and nist.c * tests/check_log_buffer.c New file implementing check_log_buffer () which reads the log buffer of a SNDFILE* object and searches for error and warning messages. Calls exit () if any are found. * tests/*.c Added calls to check_log_buffer () after each call to sf_open_XXX (). 2001-05-29 Erik de Castro Lopo * src/wav.c src/wav_ms_adpcm.c src/wav_gsm610.c Major rehack of header writing using psf_binheader_writef (). 2001-05-28 Erik de Castro Lopo * src/wav.c src/wav_ima_adpcm.c Major rehack of header writing using psf_binheader_writef (). 2001-05-27 Erik de Castro Lopo * src/wav.c Changed return type of get_encoding_str () to prevent compiler warnings on Mac OSX. * src/aiff.c src/au.c Major rehack of header writing using psf_binheader_writef (). 2001-05-25 Erik de Castro Lopo * src/common.h src/common.c Added comments. Name of log buffer changed from strbuffer to logbuffer. Name of log buffer index variable changed from strindex to logindex. * src/*.[ch] Changed name of internal logging function from psf_sprintf () to psf_log_printf (). Changed name of internal header generation functions from psf_[ab]h_printf () to psf_asciiheader_printf () and psf_binheader_writef (). Changed name of internal header manipulation function psf_hsetf () to psf_header_setf (). 2001-05-24 Erik de Castro Lopo * src/nist.c Fixed reading and writing of sample_byte_format header. "01" means little endian and "10" means big endian regardless of bit width. * configure.in Detect Mac OSX and disable -Wall and -pedantic gcc options. Mac OSX is way screwed up and spews out buckets of warning messages from the system headers. Added --disable-gcc-opt configure option (sets gcc optimisation to -O0 ) for easier debugging. Made decision to harmonise source code version number and .so library version number. Future releases will stick to this rule. * doc/new_file_type.HOWTO New file to document the addition of new file types to libsndfile. 2001-05-23 Erik de Castro Lopo * src/nist.c New file for reading/writing Sphere NIST audio file format. Originally requested by Elis Pomales in 1999. Retrieved from unstable (and untouched for 18 months) branch of libsndfile. Some vital information gleaned from the source code to Bill Schottstaedt's sndlib library : ftp://ccrma-ftp.stanford.edu/pub/Lisp/sndlib.tar.gz Currently reading and writing 16, 24 and 32 bit, big-endian and little endian, stereo and mono files. * src/common.h src/common.c Added psf_ah_printf () function to help construction of ASCII headers (ie NIST). * configure.in Added test for vsnprintf () required by psf_ah_printf (). * tests/write_read_test.c Added tests for supported NIST files. 2001-05-22 Erik de Castro Lopo * tests/write_read_test.c Added tests for little endian AIFC files. * src/aiff.c Minor re-working of aiff_open_write (). Added write support for little endian PCM encoded AIFC files. 2001-05-13 Erik de Castro Lopo * src/aiff.c Minor re-working of aiff_open_read (). Added read support for little endian PCM encoded AIFC files from the Mac OSX CD ripper program. Guillaume Lessard provided a couple of sample files and a working patch. The patch was not used as is but gave a good guide as to what to do. 2001-05-11 Erik de Castro Lopo * src/sndfile.h Fixed comments about endian-ness of WAV and AIFF files. Guillaume Lessard pointed out the error. 2001-04-23 Erik de Castro Lopo * examples/make_sine.c Re-write of this example using sample rate and required frequency in Hz. 2001-02-11 Erik de Castro Lopo * src/sndfile.c Fixed bug that prevented known file types from being read as RAW PCM data. 2000-12-16 Erik de Castro Lopo * src/aiff.c Added handing of COMT chunk. 2000-11-16 Erik de Castro Lopo * examples/sfconvert.c Fixed bug in normalisatio code. Pointed out by Johnny Wu. 2000-11-08 Erik de Castro Lopo * Win32/config.h Fixed the incorrect setting of HAVE_ENDIAN_H parameter. Win32 only issue. 2000-10-27 Erik de Castro Lopo * tests/Makefile.am Added -lm for write_read_test_LDADD. 2000-10-16 Erik de Castro Lopo * src/sndfile.c src/au.c Fixed bug which prevented writing of G723 24kbps AU files. * tests/lossy_comp_test.c Corrrection to options for G723 tests. * configure.in Added --disable-gcc-pipe option for DJGPP compiler (gcc on MS-DOS) which doesn't allow gcc -pipe option. 2000-09-03 Erik de Castro Lopo * src/ulaw.c src/alaw.c src/wav_imaadpcm.c src/msadpcm.c src/wav_gsm610.c Fixed normailsation bugs shown up by new double_test program. 2000-08-31 Erik de Castro Lopo * src/pcm.c Fixed bug in normalisation code (spotted by Steve Lhomme). * tests/double_test.c New file to test scaled and unscaled sf_read_double() and sf_write_double() functions. 2000-08-28 Erik de Castro Lopo * COPYING Changed to the LGPL COPYING file (spotted by H. S. Teoh). 2000-08-21 Erik de Castro Lopo * src/sndfile.h Removed prototype of unimplemented function sf_get_info(). Added prototype for sf_error_number() Thanks to Sigbjørn Skjæret for spotting these. 2000-08-18 Erik de Castro Lopo * src/newpcm.h New file to contain a complete rewrite of the PCM data handling. 2000-08-15 Erik de Castro Lopo * src/sndfile.c Fixed a leak of FILE* pointers in sf_open_write(). Thanks to Sigbjørn Skjæret for spotting this one. 2000-08-13 Erik de Castro Lopo * src/au_g72x.c src/G72x/g72x.c Added G723 encoded AU file support. * tests/lossy_comp_test.c Added tests for G721 and G723 encoded AU files. 2000-08-06 Erik de Castro Lopo * all files Changed the license to LGPL. Albert Faber who had copyright on Win32/unistd.h gave his permission to change the license on that file. All other files were either copyright erikd AT mega-nerd DOT com or copyright under a GPL/LGPL compatible license. 2000-08-06 Erik de Castro Lopo * tests/lossy_comp_test.c Fixed incorrect error message. * src/au_g72x.c src/G72x/* G721 encoded AU files now working. * Win32/README-Win32.txt Replaced this file with a new one which gives a full explanation of how to build libsndfile under Win32. Thanks to Mike Ricos. 2000-08-05 Erik de Castro Lopo * src/*.[ch] Removed double leading underscores from the start of all variable and function names. Identifiers with a leading underscores are reserved for use by the compiler. * src/au_g72x.c src/G72x/* Continued work on G721 encoded AU files. 2000-07-12 Erik de Castro Lopo * src/G72x/* New files for reading/writing G721 and G723 ADPCM audio. These files are from a Sun Microsystems reference implementation released under a free software licence. Extensive changes to this code to make it fit in with libsndfile. See the ChangeLog in this directory for details. * src/au_g72x.c New file for G721 encoded AU files. 2000-07-08 Erik de Castro Lopo * libsndfile.spec.in Added a spec file for making RPMs. Thanks to Josh Green for supplying this. 2000-06-28 Erik de Castro Lopo * src/sndfile.c src/sndfile.h Add checking for and handling of header-less u-law encoded AU/SND files. Any file with a ".au" or ".snd" file extension and without the normal AU file header is treated as an 8kHz, u-law encoded file. * src/au.h New function for opening a headerless u-law encoded file for read. 2000-06-04 Erik de Castro Lopo * src/paf.c Add checking for files shorter than minimal PAF file header length. 2000-06-02 Erik de Castro Lopo * tests/write_read_test.c Added extra sf_perror() calls when sf_write_XXXX fails. 2000-05-29 Erik de Castro Lopo * src/common.c Modified usage of va_arg() macro to work correctly on PowerPC Linux. Thanks to Kyle Wheeler for giving me ssh access to his machine while I was trying to track this down. * configure.in src/*.[ch] Sorted out some endian-ness issues brought up by PowerPC Linux. * tests/read_seek_test.c Added extra debugging for when tests fail. 2000-05-18 Erik de Castro Lopo * src/wav.c Fixed bug in GSM 6.10 handling for big-endian machines. Thanks to Sigbjørn Skjæret for reporting this. 2000-04-25 Erik de Castro Lopo * src/sndfile.c src/wav.c src/wav_gsm610.c Finallised writing of GSM 6.10 WAV files. * tests/lossy_comp_test.c Wrote new test code for GSM 6.10 files. * examples/sfinfo.c Fixed incorrect format in printf() statement. 2000-04-06 Erik de Castro Lopo * src/sndfile.h.in Fixed comments about sf_perror () and sf_error_str (). 2000-03-14 Erik de Castro Lopo * configure.in Fixed --enable-justsrc option. 2000-03-07 Erik de Castro Lopo * wav.c Fixed checking of bytespersec field of header. Still some weirdness with some files. 2000-03-05 Erik de Castro Lopo * tests/lossy_comp_test.c Added option to test PCM WAV files (sanity check). Fixed bug in sf_seek() tests. 2000-02-29 Erik de Castro Lopo * src/sndfile.c src/wav.c Minor changes to allow writing of GSM 6.10 WAV files. 2000-02-28 Erik de Castro Lopo * configure.in Makefile.am src/Makefile.am Finally got around to figuring out how to build a single library from multiple source directories. Reading GSM 6.10 files now seems to work. 2000-01-03 Erik de Castro Lopo * src/wav.c Added more error reporting in read_fmt_chunk(). 1999-12-21 Erik de Castro Lopo * examples/sfinfo.c Modified program to accept multiple filenames from the command line. 1999-11-27 Erik de Castro Lopo * src/wav_ima_adpcm.c Moved code around in preparation to adding ability to read/write IMA ADPCM encoded AIFF files. 1999-11-16 Erik de Castro Lopo * src/common.c Fixed put_int() and put_short() macros used by _psf_hprintf() which were causing seg. faults on Sparc Solaris. 1999-11-15 Erik de Castro Lopo * src/common.c Added string.h to includes. Thanks to Sigbjxrn Skjfret. * src/svx.c Fixed __svx_close() function to ensure FORM and BODY chunks are correctly set. 1999-10-01 Erik de Castro Lopo * src/au.c Fixed handling of incorrect size field in AU header on read. Thanks to Christoph Lauer for finding this problem. 1999-09-28 Erik de Castro Lopo * src/aiff.c Fixed a bug with incorrect SSND chunk length being written. This also lead to finding an minor error in AIFF header parsing. Thanks to Dan Timis for pointing this out. 1999-09-24 Erik de Castro Lopo * src/paf.c Fixed a bug with reading and writing 24 bit stereo PAF files. This problem came to light when implementing tests for the new functions which operate in terms of frames rather than items. 1999-09-23 Erik de Castro Lopo * src/sndfile.c Modified file type detection to use first 12 bytes of file rather than file name extension. Required this because NIST files use the same filename extension as Microsoft WAV files. * src/sndfile.c src/sndfile.h Added short, int and double read/write functions which work in frames rather than items. This was originally suggested by Maurizio Umberto Puxeddu. 1999-09-22 Erik de Castro Lopo * src/svx.c Finished off implementation of write using __psf_hprintf(). 1999-09-21 Erik de Castro Lopo * src/common.h Added a buffer to SF_PRIVATE for writing the header. This is required to make generating headers for IFF/SVX files easier as well as making it easier to do re-write the headers which will be required when sf_rewrite_header() is implemented. * src/common.c Implemented __psf_hprintf() function. This is an internal function which is documented briefly just above the code. 1999-09-05 Erik de Castro Lopo * src/sndfile.c Fixed a bug in sf_write_raw() where it was returning incorrect values (thanks to Richard Dobson for finding this one). Must put in a test routine for sf_read_raw and sf_write_raw. * src/aiff.c Fixed default FORMsize in __aiff_open_write (). * src/sndfile.c Added copy of filename to internal data structure. IFF/SVX files contain a NAME header chunk. Both sf_open_read() and sf_open_write() copy the file name (less the leading path information) to the filename field. * src/svx.c Started implementing writing of files. 1999-08-04 Erik de Castro Lopo * src/svx.c New file for reading/writing 8SVX and 16SVX files. * src/sndfile.[ch] src/common.h Changes for SVX files. * src/aiff.c Fixed header parsing when unknown chunk is found. 1999-08-01 Erik de Castro Lopo * src/paf.c New file for reading/writing Ensoniq PARIS audio file format. * src/sndfile.[ch] src/common.h Changes for PAF files. * src/sndfile.[ch] Added stuff for sf_get_lib_version() function. 1999-07-31 Erik de Castro Lopo * src/sndfile.h MacOS/config.h Fixed minor MacOS configuration issues. 1999-07-30 Erik de Castro Lopo * MacOS/ Added a new directory for the MacOS config.h file and the readme file. * src/aiff.c Fixed calculation of datalength when reading SSND chunk. Thanks to Sigbjørn Skjæret for pointing out this error. 1999-07-29 Erik de Castro Lopo * src/sndfile.c src/sndfile.h src/raw.c Further fixing of #includes for MacOS. 1999-07-25 Erik de Castro Lopo * src/wav.c src/aiff.c Added call to ferror () in main header parsing loop of __XXX_open_read functions. This should fix problems on platforms (MacOS, AmigaOS) where fseek()ing or fread()ing beyond the end of the file puts the FILE* stream in an error state until clearerr() is called. * tests/write_read_test.c Added tests for RAW header-less PCM files. * src/common.h Moved definition of struct tribyte to pcm.c which is the only place which needs it. * src/pcm.c Modified all code which assumed sizeof (struct tribyte) == 3. This code did not work on MacOS. Thanks to Ben "Jacobs" for pointing this out. * src/au.c Removed from list of #includes (not being used). * src/sndfile.c Added MacOS specific #ifdef to replace . * src/sndfile.h Added MacOS specific #ifdef to replace . * src/sndfile.h Added MacOS specific typedef for off_t. * MacOS-readme.txt New file with instructions for building libsndfile under MacOS. Thanks to Ben "Jacobs" for supplying these instructions. 1999-07-24 Erik de Castro Lopo * configure.in Removed sndfile.h from generated file list as there were no longer any autoconf substitutions being made. * src/raw.c New file for handling raw header-less PCM files. In order to open these for read, the user must specify format, pcmbitwidth and channels in the SF_INFO struct when calling sf_open_read (). * src/sndfile.c Added support for raw header-less PCM files. 1999-07-22 Erik de Castro Lopo * examples/sfinfo.c Removed options so the sfinfo program always prints out all the information. 1999-07-19 Erik de Castro Lopo * src/alaw.c New file for A-law encoding (similar to u-law). * tests/alaw_test.c New test program to test the A-law encode/decode lookup tables. * tests/lossy_comp_test.c Added tests for a-law encoded WAV, AU and AULE files. 1999-07-18 Erik de Castro Lopo * src/sndfile.c src/au.c Removed second "#include ". Thanks to Ben "Jacobs" for pointing this out. 1999-07-18 Erik de Castro Lopo * tests/ulaw_test.c New test program to test the u-law encode/decode lookup tables. 1999-07-16 Erik de Castro Lopo * src/sndfile.h Made corrections to comments on the return values from sf_seek (). * src/sndfile.c Fixed boundary condition checking bug and accounting bug in sf_read_raw (). 1999-07-15 Erik de Castro Lopo * src/au.c src/ulaw.c Finished implementation of u-law encoded AU files. * src/wav.c Implemented reading and writing of u-law encoded WAV files. * tests/ Changed name of adpcm_test.c to lossy_comp_test.c. This test program will now be used to test Ulaw and Alaw encoding as well as APDCM. Added tests for Ulaw encoded WAV files. 1999-07-14 Erik de Castro Lopo * tests/adpcm_test.c Initialised amp variable in gen_signal() to remove compiler warning. 1999-07-12 Erik de Castro Lopo * src/aiff.c In __aiff_open_read () prevented fseek()ing beyond end of file which was causing trouble on MacOS with the MetroWerks compiler. Thanks to Ben "Jacobs" for pointing this out. *src/wav.c Fixed as above in __wav_open_read (). 1999-07-01 Erik de Castro Lopo * src/wav_ms_adpcm.c Implemented MS ADPCM encoding. Code cleanup of decoder. * tests/adpcm_test.c Added tests for MS ADPCM WAV files. * src/wav_ima_adpcm.c Fixed incorrect parameter in call to srate2blocksize () from __ima_writer_init (). 1999-06-23 Erik de Castro Lopo * tests/read_seek_test.c Added test for 8 bit AIFF files. 1999-06-18 Erik de Castro Lopo * tests/write_read_test.c Removed test for IMA ADPCM WAV files which is now done in adpcm_test.c * configure.in Added -Wconversion to CFLAGS. * src/*.c tests/*.c examples/*.c Fixed all warnings resulting from use of -Wconversion. 1999-06-17 Erik de Castro Lopo * src/wav.c Added fact chunk handling on read and write for all non WAVE_FORMAT_PCM WAV files. * src/wav_ima.c Changed block alignment to be dependant on sample rate. This should make WAV files created with libsndfile compatible with the MS Windows media players. * tests/adpcm_test.c Reimplemented adpcm_test_short and implemented adpcm_test_int and adpcm_test_double. Now have full testing of IMA ADPCM WAV file read, write and seek. 1999-06-15 Erik de Castro Lopo * src/wav_float.c Fixed function prototype for x86f2d_array () which was causing ocassional seg. faults on Sparc Solaris machines. 1999-06-14 Erik de Castro Lopo * src/aiff.c Fixed bug in __aiff_close where the length fields in the header were not being correctly calculated before writing. * tests/write_read_test.c Modified to detect the above bug in WAV, AIFF and AU files. 1999-06-12 Erik de Castro Lopo * Win32/* Added a contribution from Albert Faber to allow libsndfile to compile under Win32 systems. libsndfile will now be used as part of LAME the the MPEG 1 Layer 3 encoder (http://internet.roadrunner.com/~mt/mp3/). 1999-06-11 Erik de Castro Lopo * configure.in Changed to reflect previous changes. * src/wav_ima_adpcm.c Fixed incorrect calculation of bytespersec header field (IMA ADPCM only). Fixed bug when writing from int or double data to IMA ADPCM file. Will need to write test code for this. Fixed bug in __ima_write () whereby the length of the current block was calculated incorrectly. Thanks to Jongcheon Park for pointing this out. 1999-03-27 Erik de Castro Lopo * src/*.c Changed all read/write/lseek function calls to fread/fwrite/ fseek/ftell and added error checking of return values from fread and fwrite in critical areas of the code. * src/au.c Fixed incorrect datasize element in AU header on write. * tests/error_test.c Add new test to check all error values have an associated error string. This will avoid embarrassing real world core dumps. 1999-03-23 Erik de Castro Lopo * src/wav.c src/aiff.c Added handling for unknown chunk markers in the file. 1999-03-22 Erik de Castro Lopo * src/sndfile.c Filled in missing error strings in SndfileErrors array. Missing entries can cause core dumps when calling sf_error-str (). Thanks to Sam for finding this problem. 1999-03-21 Erik de Castro Lopo * src/wav_ima_adpcm.c Work on wav_ms_adpcm.c uncovered a bug in __ima_read () when reading stereo files. Caused by not adjusting offset into buffer of decoded samples for 2 channels. A similar bug existed in __ima_write (). Need a test for stereo ADPCM files. * src/wav_ms_adpcm.c Decoder working correctly. 1999-03-18 Erik de Castro Lopo * configure.in Makefile.am Added --enable-justsrc configuration variable sent by Sam . * src/wav_ima_adpcm.c Fixed bug when reading beyond end of data section due to not checking pima->blockcount. This uncovered __ima_seek () bug due to pima->blockcount being set before calling __ima_init_block (). 1999-03-17 Erik de Castro Lopo * src/wav.c Started implementing MS ADPCM decoder. If file is WAVE_FORMAT_ADPCM and length of data chunk is odd, this encoder seems to add an extra byte. Why not just give an even data length? 1999-03-16 Erik de Castro Lopo * src/wav.c Split code out of wav.c to create wav_float.c and wav_ima_adpcm.c. This will make it easier to add and debug other kinds of WAV files in future. 1999-03-14 Erik de Castro Lopo * tests/ Added adpcm_test.c which implements test functions for IMA ADPCM reading/writing/seeking etc. * src/wav.c Fixed many bugs in IMA ADPCM encoder and decoder. 1999-03-11 Erik de Castro Lopo * src/wav.c Finished implementing IMA ADPCM encoder and decoder (what a bitch!). 1999-03-03 Erik de Castro Lopo * src/wav.c Started implementing IMA ADPCM decoder. 1999-03-02 Erik de Castro Lopo * src/sndfile.c Fixed bug where the sf_read_XXX functions were returning a incorrect read count when reading past end of file. Fixed bug in sf_seek () when seeking backwards from end of file. * tests/read_seek_test.c Added multiple read test to short_test(), int_test () and double_test (). Added extra chunk to all test WAV files to test that reading stops at end of 'data' chunk. 1999-02-21 Erik de Castro Lopo * tests/write_read_test.c Added tests for little DEC endian AU files. * src/au.c Add handling for DEC format little endian AU files. 1999-02-20 Erik de Castro Lopo * src/aiff.c src/au.c src/wav.c Add __psf_sprintf calls during header parsing. * src/sndfile.c src/common.c Implement sf_header_info (sndfile.c) function and __psf_sprintf (common.c). * tests/write_read_test.c Added tests for 8 bit PCM files (WAV, AIFF and AU). * src/au.c src/aiff.c Add handling of 8 bit PCM data format. * src/aiff.c On write, set blocksize in SSND chunk to zero like everybody else. 1999-02-16 Erik de Castro Lopo * src/pcm.c: Fixed bug in let2s_array (cptr was not being initialised). * src/sndfile.c: Fixed bug in sf_read_raw and sf_write_raw. sf_seek should now work when using these functions. 1999-02-15 Erik de Castro Lopo * tests/write_read_test.c: Force test_buffer array to be double aligned. Sparc Solaris requires this. 1999-02-14 Erik de Castro Lopo * src/pcm.c: Fixed a bug which was causing errors in the reading and writing of 24 bit PCM files. * doc/api.html Finished of preliminary documentaion. 1999-02-13 Erik de Castro Lopo * src/aiff.c: Changed reading of 'COMM' chunk to avoid reading an int which overlaps an int (4 byte) boundary. libsndfile-1.0.28/sndfile.pc.in0000644000175000017500000000042212764737573013236 00000000000000prefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@ Name: sndfile Description: A library for reading and writing audio files Requires: Version: @VERSION@ Libs: -L${libdir} -lsndfile Libs.private: @EXTERNAL_XIPH_LIBS@ Cflags: -I${includedir} libsndfile-1.0.28/configure.ac0000644000175000017500000005420213070135662013132 00000000000000# Copyright (C) 1999-2017 Erik de Castro Lopo . dnl Require autoconf version AC_PREREQ(2.57) AC_INIT([libsndfile],[1.0.28],[sndfile@mega-nerd.com], [libsndfile],[http://www.mega-nerd.com/libsndfile/]) # Put config stuff in Cfg.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

Q5 : Why doesn't libsndfile do interleaving/de-interleaving?
Q6 : What's the best format for storing temporary files?
Q7 : On Linux/Unix/MacOS X, what's the best way of detecting the presence of libsndfile?
Q8 : I have libsndfile installed and now I want to use it. I just want a simple Makefile! What do I do?
Q9 : How about adding the ability to write/read sound files to/from memory buffers?
Q10 : Reading a 16 bit PCM file as normalised floats and then writing them back changes some sample values. Why?
Q11 : I'm having problems with u-law encoded WAV files generated by libsndfile in Winamp. Why?
Q12 : I'm looking at sf_read*. What are items? What are frames?
Q13 : Why can't libsndfile open this Sound Designer II (SD2) file?
Q14 : I'd like to statically link libsndfile to my closed source application. Can I buy a license so that this is possible?
Q15 : My program is crashing during a call to a function in libsndfile. Is this a bug in libsndfile?
Q16 : Will you accept a fix for compiling libsndfile with compiler X?
Q17 : Can libsndfile read/write files from/to UNIX pipes?
Q18 : Is it possible to build a Universal Binary on Mac OS X?
Q19 : I have project files for Visual Studio / XCode / Whatever. Why don't you distribute them with libsndfile?
Q20 : Why doesn't libsndfile support MP3? Lots of other Open Source projects support it!
Q21 : How do I use libsndfile in a closed source or commercial program and comply with the license?
Q22 : What versions of windows does libsndfile work on?
Q23 : I'm cross compiling libsndfile for another platform. How can I run the test suite?


Q1 : Do you plan to support XYZ codec in libsndfile?

If source code for XYZ codec is available under a suitable license (LGPL, BSD, MIT etc) then yes, I'd like to add it.

If suitable documentation is available on how to decode and encode the format then maybe, depending on how much work is involved.

If XYZ is some proprietary codec where no source code or documentation is available then no.

So if you want support for XYZ codec, first find existing source code or documentation. If you can't find either then the answer is no.


Q2 : In version 0 the SF_INFO struct had a pcmbitwidth field but version 1 does not. Why?

This was dropped for a number of reasons:

  • pcmbitwidth makes little sense on compressed or floating point formats
  • with the new API you really don't need to know it

As documented here there is now a well defined behaviour which ensures that no matter what the bit width of the source file, the scaling always does something sensible. This makes it safe to read 8, 16, 24 and 32 bit PCM files using sf_read_short() and always have the optimal behaviour.


Q3 : Compiling is really slow on MacOS X. Why?

When you configure and compile libsndfile, it uses the /bin/sh shell for a number of tasks (ie configure script and libtool). Older versions of OS X (10.2?) shipped a really crappy Bourne shell as /bin/sh which resulted in really slow compiles. Newer version of OS X ship GNU Bash as /bin/sh and this answer doesn't apply in that case.

To fix this I suggest that you install the GNU Bash shell, rename /bin/sh to /bin/sh.old and make a symlink from /bin/sh to the bash shell. Bash is designed to behave as a Bourne shell when is is called as /bin/sh.

When I did this on my iBook running MacOS X, compile times dropped from 13 minutes to 3 minutes.


Q4 : When trying to compile libsndfile on Solaris I get a "bad substitution" error on linking. Why?

It seems that the Solaris Bourne shell disagrees with GNU libtool.

To fix this I suggest that you install the GNU Bash shell, rename /bin/sh to /bin/sh.old and make a symlink from /bin/sh to the bash shell. Bash is designed to behave as a Bourne shell when is is called as /bin/sh.


Q5 : Why doesn't libsndfile do interleaving/de-interleaving?

This problem is bigger than it may seem at first.

For a stereo file, it is a pretty safe bet that a simple interleaving/de-interleaving could satisfy most users. However, for files with more than 2 channels this is unlikely to be the case. If the user has a 4 channel file and want to play that file on a stereo output sound card they either want the first 2 channels or they want some mixed combination of the 4 channels.

When you add more channels, the combinations grow exponentially and it becomes increasingly difficult to cover even a sensible subset of the possible combinations. On top of that, coding any one style of interleaver/de-interleaver is trivial, while coding one that can cover all combinations is far from trivial. This means that this feature will not be added any time soon.


Q6 : What's the best format for storing temporary files?

When you want to store temporary data there are a number of requirements;

  • A simple, easy to parse header.
  • The format must provide the fastest possible read and write rates (ie avoid conversions and encoding/decoding).
  • The file format must be reasonably common and playable by most players.
  • Able to store data in either endian-ness.

The format which best meets these requirements is AU, which allows data to be stored in any one of short, int, float and double (among others) formats.

For instance, if an application uses float data internally, its temporary files should use a format of (SF_ENDIAN_CPU | SF_FORMAT_AU | SF_FORMAT_FLOAT) which will store big endian float data in big endian CPUs and little endian float data on little endian CPUs. Reading and writing this format will not require any conversions or byte swapping regardless of the host CPU.


Q7 : On Linux/Unix/MaxOS X, what's the best way of detecting the presence of libsndfile using autoconf?

libsndfile uses the pkg-config (man pkg-config) method of registering itself with the host system. The best way of detecting its presence is using something like this in configure.ac (or configure.in): 

        PKG_CHECK_MODULES(SNDFILE, sndfile >= 1.0.2, ac_cv_sndfile=1, ac_cv_sndfile=0)

        AC_DEFINE_UNQUOTED([HAVE_SNDFILE],${ac_cv_sndfile},
			[Set to 1 if you have libsndfile.])

        AC_SUBST(SNDFILE_CFLAGS)
        AC_SUBST(SNDFILE_LIBS)

This will automatically set the SNDFILE_CFLAGS and SNDFILE_LIBS variables which can be used in Makefile.am like this: 

        SNDFILE_CFLAGS = @SNDFILE_CFLAGS@
        SNDFILE_LIBS = @SNDFILE_LIBS@

If you install libsndfile from source, you will probably need to set the PKG_CONFIG_PATH environment variable as suggested at the end of the libsndfile configure process. For instance on my system I get this: 

        -=-=-=-=-=-=-=-=-=-= Configuration Complete =-=-=-=-=-=-=-=-=-=-

          Configuration summary :

            Version : ..................... 1.0.5
            Experimental code : ........... no

          Tools :

            Compiler is GCC : ............. yes
            GCC major version : ........... 3

          Installation directories :

            Library directory : ........... /usr/local/lib
            Program directory : ........... /usr/local/bin
            Pkgconfig directory : ......... /usr/local/lib/pkgconfig

        Compiling some other packages against libsndfile may require
        the addition of "/usr/local/lib/pkgconfig" to the
        PKG_CONFIG_PATH environment variable.


Q8 : I have libsndfile installed and now I want to use it. I just want a simple Makefile! What do I do?

The pkg-config program makes finding the correct compiler flag values and library location far easier. During the installation of libsndfile, a file named sndfile.pc is installed in the directory ${libdir}/pkgconfig (ie if libsndfile is installed in /usr/local/lib, sndfile.pc will be installed in /usr/local/lib/pkgconfig/).

In order for pkg-config to find sndfile.pc it may be necessary to point the environment variable PKG_CONFIG_PATH in the right direction. 

        export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Then, to compile a C file into an object file, the command would be: 

        gcc `pkg-config --cflags sndfile` -c somefile.c

and to link a number of objects into an executable that links against libsndfile, the command would be: 

        gcc `pkg-config --libs sndfile` obj1.o obj2.o -o program


Q9 : How about adding the ability to write/read sound files to/from memory buffers?

This has been added for version 1.0.13.


Q10 : Reading a 16 bit PCM file as normalised floats and then writing them back changes some sample values. Why?

This is caused by the fact that the conversion from 16 bit short to float is done by dividing by 32768 (0x8000 in hexadecimal) while the conversion from float to 16 bit short is done by multiplying by 32767 (0x7FFF in hex). So for instance, a value in a 16 bit PCM file of 20000 gets read as a floating point number of 0.6103515625 (20000.0 / 0x8000). Converting that back to a 16 bit short results in a value of 19999.3896484375 (0.6103515625 * 0x7FFF) which then gets rounded down to 19999.

You will notice that for this particular case, the error is 1 in 20000 or 0.005%. Interestingly, for values of less than 16369, dividing by 0x8000 followed by multiplying by 0x7FFF and then rounding the result, gives back the original value. It turns out that as long as the host operating system supplies the 1999 ISO C Standard functions lrintf and lrint (or a replacement has been supplied) then the maximum possible error is 1 in 16369 or about 0.006%.

Regardless of the size of the error, the reason why this is done is rather subtle.

In a file containing 16 bit PCM samples, the values are restricted to the range [-32768, 32767] while we want floating point values in the range [-1.0, 1.0]. The only way to do this conversion is to do a floating point division by a value of 0x8000. Converting the other way, the only way to ensure that floating point values in the range [-1.0, 1.0] are within the valid range allowed by a 16 bit short is to multiply by 0x7FFF.

Some people would say that this is a severe short-coming of libsndfile. I would counter that anybody who is constantly converting back and forth between 16 bit shorts and normalised floats is going to suffer other losses in audio quality that they should also be concerned about.

Since this problem only occurs when converting between integer data on disk and normalized floats in the application, it can be avoided by using something other than normalized floats in the application. Alternatives to normalized floats are the short and int data types (ie using sf_read_short or sf_read_int) or using un-normalized floats (see SFC_SET_NORM_FLOAT).

Another way to deal with this problem is to consider 16 bit short data as a final destination format only, not as an intermediate storage format. All intermediate data (ie which is going to be processed further) should be stored in floating point format which is supported by all of the most common file formats. If floating point files are considered too large (2 times the size of a 16 bit PCM file), it would also be possible to use 24 bit PCM as an intermediate storage format (and which is also supported by most common file types).


Q11 : I'm having problems with u-law encoded WAV files generated by libsndfile in Winamp. Why?

This is actually a Winamp problem. The official Microsoft spec suggests that the 'fmt ' chunk should be 18 bytes. Unfortunately at least one of Microsoft's own applications (Sound Recorder on Win98 I believe) did not accept 18 bytes 'fmt ' chunks.

Michael Lee did some experimenting and found that: 

    I have checked that Windows Media Player 9, QuickTime Player 6.4,
    RealOne Player 2.0 and GoldWave 5.06 can all play u-law files with
    16-byte or 18-byte 'fmt ' chunk. Only Winamp (2.91) and foobar2000
    are unable to play u-law files with 16-byte 'fmt ' chunk.

Even this is a very small sampling of all the players out there. For that reason it is probably not a good idea to change this now because there is the risk of breaking something that currently works.


Q12 : I'm looking at sf_read*. What are items? What are frames?

An item is a single sample of the data type you are reading; ie a single short value for sf_read_short or a single float for sf_read_float.

For a sound file with only one channel, a frame is the same as a item (ie a single sample) while for multi channel sound files, a single frame contains a single item for each channel.

Here are two simple, correct examples, both of which are assumed to be working on a stereo file, first using items: 

        #define CHANNELS 2
        short data [CHANNELS * 100] ;
        sf_count items_read = sf_read_short (file, data, 200) ;
        assert (items_read == 200) ;

and now reading the exact same amount of data using frames: 

        #define CHANNELS 2
        short data [CHANNELS * 100] ;
        sf_count frames_read = sf_readf_short (file, data, 100) ;
        assert (frames_read == 100) ;


Q13 : Why can't libsndfile open this Sound Designer II (SD2) file?

This is somewhat complicated. First some background.

SD2 files are native to the Apple Macintosh platform and use features of the Mac filesystem (file resource forks) to store the file's sample rate, number of channels, sample width and more. When you look at a file and its resource fork on Mac OS X it looks like this: 

        -rw-r--r--  1 erikd erikd   46512 Oct 18 22:57 file.sd2
        -rw-r--r--  1 erikd erikd     538 Oct 18 22:57 file.sd2/rsrc

Notice how the file itself looks like a directory containing a single file named rsrc. When libsndfile is compiled for MacOS X, it should open (for write and read) SD2 file with resource forks like this without any problems. It will also handle files with the resource fork in a separate file as described below.

When SD2 files are moved to other platforms, the resource fork of the file can sometimes be dropped altogether. All that remains is the raw audio data and no information about the number of channels, sample rate or bit width which makes it a little difficult for libsndfile to open the file.

However, it is possible to safely move an SD2 file to a Linux or Windows machine. For instance, when an SD2 file is copied from inside MacOS X to a windows shared directory or a Samba share (ie Linux), MacOS X is clever enough to store the resource fork of the file in a separate hidden file in the same directory like this: 

        -rw-r--r--  1 erikd erikd     538 Oct 18 22:57 ._file.sd2
        -rw-r--r--  1 erikd erikd   46512 Oct 18 22:57 file.sd2

Regardless of what platform it is running on, when libsndfile is asked to open a file named "foo" and it can't recognize the file type from the data in the file, it will attempt to open the resource fork and if that fails, it then tries to open a file named "._foo" to see if the file has a valid resource fork. This is the same regardless of whether the file is being opened for read or write.

In short, libsndfile should open SD2 files with a valid resource fork on all of the platforms that libsndfile supports. If a file has lost its resource fork, the only option is the open the file using the SF_FORMAT_RAW option and guessing its sample rate, channel count and bit width.

Occasionally, when SD2 files are moved to other systems, the file is BinHexed which wraps the resource fork and the data fork together. For these files, it would be possible to write a BinHex parser but there is not a lot to gain considering how rare these BinHexed SD2 files are.


Q14 : I'd like to statically link libsndfile to my closed source application. Can I buy a license so that this is possible?

Unfortunately no. libsndfile contains code written by other people who have agreed that their code be used under the GNU LGPL but no more. Even if they were to agree, there would be significant difficulties in dividing up the payments fairly.

The only way you can legally use libsndfile as a statically linked library is if your application is released under the GNU GPL or LGPL.


Q15 : My program is crashing during a call to a function in libsndfile. Is this a bug in libsndfile?

libsndfile is being used by large numbers of people all over the world without any problems like this. That means that it is much more likely that your code has a bug than libsndfile. However, it is still possible that there is a bug in libsndfile.

To figure out whether it is your code or libsndfile you should do the following:

  • Make sure you are compiling your code with warnings switched on and that you fix as many warnings as possible. With the GNU compiler (gcc) I would recommend at least -W -Wall -Werror which will force you to fix all warnings before you can run the code.
  • Try using a memory debugger. Valgrind on x86 Linux is excellent. Purify also has a good reputation.
  • If the code is clean after the above two steps and you still get a crash in libsndfile, then send me a small snippet of code (no more than 30-40 lines) which includes the call to sf_open() and also shows how all variables passed to/returned from sf_open() are defined.


Q16 : Will you accept a fix for compiling libsndfile with compiler X?

If compiler X is a C++ compiler then no. C and C++ are different enough to make writing code that compiles as valid C and valid C++ too difficult. I would rather spend my time fixing bugs and adding features.

If compiler X is a C compiler then I will do what I can as long as that does not hamper the correctness, portability and maintainability of the existing code. It should be noted however that libsndfile uses features specified by the 1999 ISO C Standard. This can make compiling libsndfile with some older compilers difficult.


Q17 : Can libsndfile read/write files from/to UNIX pipes?

Yes, libsndfile can read files from pipes. Unfortunately, the write case is much more complicated.

File formats like AIFF and WAV have information at the start of the file (the file header) which states the length of the file, the number of sample frames etc. This information must be filled in correctly when the file header is written, but this information is not reliably known until the file is closed. This means that libsndfile cannot write AIFF, WAV and many other file types to a pipe.

However, there is at least one file format (AU) which is specifically designed to be written to a pipe. Like AIFF and WAV, AU has a header with a sample frames field, but it is specifically allowable to set that frames field to 0x7FFFFFFF if the file length is not known when the header is written. The AU file format can also hold data in many of the standard formats (ie SF_FORMAT_PCM_16, SF_FORMAT_PCM_24, SF_FORMAT_FLOAT etc) as well as allowing data in both big and little endian format.

See also FAQ Q6.


Q18 : Is it possible to build a Universal Binary on Mac OS X?

Yes, but you must do two separate configure/build/test runs; one on PowerPC and one on Intel. It is then possible to merge the binaries into a single universal binary using one of the programs in the Apple tool chain.

It is not possible to build a working universal binary via a single compile/build run on a single CPU.

The problem is that the libsndfile build process detects features of the CPU its being built for during the configure process and when building a universal binary, configure is only run once and that data is then used for both CPUs. That configure data will be wrong for one of those CPUs. You will still be able to compile libsndfile, and the test suite will pass on the machine you compiled it on. However, if you take the universal binary test suite programs compiled on one CPU and run them on the other, the test suite will fail.

Part of the problem is that the CPU endian-ness is detected at configure time. Yes, I know the Apple compiler defines one of the macros __LITTLE_ENDIAN__ and __BIG_ENDIAN__, but those macros are not part of the 1999 ISO C Standard and they are not portable.

Endian issues are not the only reason why the cross compiled binary will fail. The configure script also detects other CPU specific idiosyncrasies to provide more optimized code.

Finally, the real show stopper problem with universal binaries is the problem with the test suite. libsndfile contains a huge, comprehensive test suite. When you compile a universal binary and run the test suite, you only test the native compile. The cross compiled binary (the one with the much higher chance of having problems) cannot be tested.

Now, if you have read this far you're probably thinking there must be a way to fix this and there probably is. The problem is that its a hell of a lot of work and would require significant changes to the configure process, the internal code and the test suite. In addition, these changes must not break compilation on any of the platforms libsndfile is currently working on.


Q19 : I have project files for Visual Studio / XCode / Whatever. Why don't you distribute them with libsndfile?

There's a very good reason for this. I will only distribute things that I actually have an ability to test and maintain. Project files for a bunch of different compilers and Integrated Development Environments are simply too difficult to maintain.

The problem is that every time I add a new file to libsndfile or rename an existing file I would have to modify all the project files and then test that libsndfile still built with all the different compilers.

Maintaining these project files is also rather difficult if I don't have access to the required compiler/IDE. If I just edit the project files without testing them I will almost certainly get it wrong. If I release a version of libsndfile with broken project files, I'll get a bunch of emails from people complaining about it not building and have no way of fixing or even testing it.

I currently release sources that I personally test on Win32, Linux and MacOS X (PowerPC) using the compiler I trust (GNU GCC). Supporting one compiler on three (actually much more because GCC is available almost everywhere) platforms is doable without too much pain. I also release binaries for Win32 with instructions on how to use those binaries with Visual Studio. As a guy who is mainly interested in Linux, I'm not to keen to jump through a bunch of hoops to support compilers and operating systems I don't use.

So, I hear you want to volunteer to maintain the project files for Some Crappy Compiler 2007? Well sorry, that won't work either. I have had numerous people over the years offer to maintaining the project files for Microsoft's Visual Studio. Every single time that happened, they maintained it for a release or two and then disappeared off the face of the earth. Hence, I'm not willing to enter into an arrangement like that again.


Q20 : Why doesn't libsndfile support MP3? Lots of other Open Source projects support it!

MP3 is not supported for one very good reason; doing so requires the payment of licensing fees. As can be seen from mp3licensing.com the required royalty payments are not cheap.

Yes, I know other libraries ignore the licensing requirements, but their legal status is extremely dubious. At any time, the body selling the licenses could go after the authors of those libraries. Some of those authors may be students and hence wouldn't be worth pursuing.

However, libsndfile is released under the name of a company, Mega Nerd Pty Ltd; a company which has income from from libsamplerate licensing, libsndfile based consulting income and other unrelated consulting income. Adding MP3 support to libsndfile could place that income under legal threat.

Fortunately, Ogg Vorbis exists as an alternative to MP3. Support for Ogg Vorbis was added to libsndfile (mostly due to the efforts of John ffitch of the Csound project) in version 1.0.18.


Q21 : How do I use libsndfile in a closed source or commercial program and comply with the license?

Here is a checklist of things you need to do to make sure your use of libsndfile in a closed source or commercial project complies with the license libsndfile is released under, the GNU Lesser General Public License (LGPL):

  • Make sure you are linking to libsndfile as a shared library (Linux and Unix systems), Dynamic Link Library (Microsoft Windows) or dynlib (Mac OS X). If you are using some other operating system that doesn't allow dynamically linked libraries, you will not be able to use libsndfile unless you release the source code to your program.
  • In the licensing documentation for your program, add a statement that your software depends on libsndfile and that libsndfile is released under the GNU Lesser General Public License, either version 2.1 or optionally version 3.
  • Include the text for both versions of the license, possibly as separate files named libsndfile_lgpl_v2_1.txt and libsndfile_lgpl_v3.txt.


Q22 : What versions of Windows does libsndfile work on?

Currently the precompiled windows binaries are thoroughly tested on Windows XP. As such, they should also work on Win2k and Windows Vista. They may also work on earlier versions of Windows.

Since version 0.1.18 I have also been releasing precompiled binaries for Win64, the 64 bit version of Windows. These binaries have received much less testing than the 32 bit versions, but should work as expected. I'd be very interested in receiving feedback on these binaries.


Q23 : I'm cross compiling libsndfile for another platform. How can I run the test suite?

Since version 1.0.21 the top level Makefile has an extra make target, 'test-tarball'. Building this target creates a tarball called called:

libsndfile-testsuite-${host_triplet}-${version}.tar.gz

in the top level directory. This tarball can then be copied to the target platform. Once untarred and test script test_wrapper.sh can be run from the top level of the extracted tarball.

libsndfile-1.0.28/doc/new_file_type.HOWTO0000644000175000017500000001073411704512754015071 00000000000000new_file_type.HOWTO =================== Original : Wed May 23 19:05:07 EST 2001 Update 1 : Fri Jul 11 22:12:38 EST 2003 This document will attempt to explain as fully as possible how to add code to libsndfile to allow the reading and writing of new file types. By new file type I particularly mean a new header type rather than a new encoding method for an existing file type. This HOWTO will take the form of a step by step guide. It will assume that you have all required tools including : - gcc - make (should really be the GNU version) - autoconf - automake - libtool These should all be available on the GNU ftp site: ftp://ftp.gnu.org/pub/gnu/. To help make these steps clearer let's suppose we are adding support for the Whacky file format whose files contain 'W','A','C' and 'K' as the first four bytes of the file format. Lets also assume that Whacky files contain PCM encoded data. Step 1 ------ Create a new .c file in the src/ directory of the libsndfile source tree. The file name should be reasonable descriptive so that is is obvious that files of the new type are handled by this file. In this particular case the file might be named 'whacky.c'. Step 2 ------ Add your new source code file to the build process. Edit the file src/Makefile.am and add the name of your file handler to the FILESPECIFIC list of handlers. This list looks something like this: FILESPECIFIC = aiff.c au.c au_g72x.c nist.c paf.c raw.c samplitude.c \ svx.c wav.c wav_float.c wav_gsm610.c wav_ima_adpcm.c \ wav_ms_adpcm.c Then, run the script named 'reconf' in the libsndfile top level directory, which will run autoconf and other associated tools. Finally run "./configure" in the top level directory. You may want to use the "--disable-gcc-opt" option to disable gcc optimisations and make debugging with gdb/ddd easier. Step 3 ------ Add a unique identifier for the new file type. Edit src/sndfile.h.in and find the enum containing the SF_FORMAT_XXX identifiers. Since you will be adding a major file type you should add your identifier to the top part of the list where the values are above 0x10000 in value. The easiest way to do this is to find the largest value in the list, add 0x10000 to it and make that your new identifier value. The identifier should be something like SF_FORMAT_WACK. Step 4 ------ Add code to the file type recogniser function. Edit src/sndfile.c and find the function guess_file_type (). This function reads the first 3 ints of the file and from that makes a guess at the file type. In our case we would add: if (buffer [0] == MAKE_MARKER ('W','A','C','K')) return SF_FORMAT_WACK ; The use of the MAKE_MARKER macro should be pretty obvious and it is defined at the top of file should you need to have a look at it. Step 5 ------ Add a call to your open function from psf_open_file (). Edit src/sndfile.c and find the switch statement in psf_open_file (). It starts like this: switch (filetype) { case SF_FORMAT_WAV : error = wav_open (psf) ; break ; case SF_FORMAT_AIFF : error = aiff_open (psf) ; break ; Towards the bottom of this switch statement your should add one for the new file type. Something like: case SF_FORMAT_WACK : sf_errno = whacky_open (psf) ; break ; Setp 6 ------ Add prototypes for new open read and open write functions. Edit src/common.h, go to the bottom of the file and add something like int whacky_open (SF_PRIVATE *psf) ; Step 7 ------ Implement your open read function. The best way to do this is by coding something much like one of the other file formats. The file src/au.c might be a good place to start. In src/whacky.c you should now implement the function whacky_open() which was prototyped in src/common.h. This function should return 0 on success and a non-zero number on error. Error values are defined in src/common.h in a enum which starts at SFE_NO_ERROR. When adding a new error value, you also need to add an error string to the SndfileErrors array in src/sndfile.c. To parse the header of your new file type you should avoid using standard read/ write/seek functions (and the fread/fwrite/fseek etc) and instead use psf_binheader_readf () which is implemented and documented in src/common.h. During the parsing process, you should also print logging information to libsndfile's internal log buffer using the psf_log_printf() function. At the end of the open read process, you should have set a number of fields in the SF_PRIVATE structure pointed to by psf. *** THIS FILE IS INCOMPLETE *** libsndfile-1.0.28/doc/AUTHORS0000644000175000017500000000364212731476267012477 00000000000000The main author of libsndfile is Erik de Castro Lopo apart from code in the following directories: - src/GSM610 : Written by Jutta Degener and Carsten Bormann .

libsndfile and GNU Octave

GNU Octave is a high-level interactive language for numerical computations. There are currently two development streams, a stable 2.0.X series and a development 2.1.X series. Octave reads and writes data in binary formats that were originally developed for MATLAB. Version 2.0.X of Octave uses binary data files compatible with MATLAB version 4.2 while Octave 2.1.X uses binary data files compatible with MATLAB version 5.0 as well as being able to read the older MATLAB 4.2 format.

From version 1.0.1 of libsndfile onwards, libsndfile has the ability of reading and writing a small subset of the binary data files used by both versions of GNU Octave. This gives people using GNU Octave for audio based work an easy method of moving audio data between GNU Octave and other programs which use libsndfile.

For instance it is now possible to do the following:

  • Load a WAV file into a sound file editor such as Sweep.
  • Save it as a MAT4 file.
  • Load the data into Octave for manipulation.
  • Save the modified data.
  • Reload it in Sweep.

Another example would be using the MAT4 or MAT5 file formats as a format which can be easily loaded into Octave for viewing/analyzing as well as a format which can be played with command line players such as the one included with libsndfile.

Details

Octave, like most programming languages, uses variables to store data, and Octave variables can contain both arrays and matrices. It is also able to store one or more of these variables in a file. When reading Octave files, libsndfile expects a file to contain two variables and their associated data. The first variable should contain a variable holding the file sample rate while the second variable contains the audio data.

For example, to generate a sine wave and store it as a binary file which is compatible with libsndfile, do the following: 

        octave:1 > samplerate = 44100 ;
        octave:2 > wavedata = sin ((0:1023)*2*pi/1024) ;
        octave:3 > save sine.mat samplerate wavedata

The process of reading and writing files compatible with libsndfile can be made easier by use of two Octave script files : 

        octave:4 > [data fs] = sndfile_load ("sine.mat") ;
        octave:5 > sndfile_save ("sine2.mat", data, fs) ;

In addition, libsndfile contains a command line program which which is able to play the correct types of Octave files. Using this command line player sndfile-play and a third Octave script file allows Octave data to be played from within Octave on any of the platforms which sndfile-play supports (at the moment: Linux, MacOS X, Solaris and Win32). 

        octave:6 > sndfile_play (data, fs) ;

These three Octave scripts are installed automatically in Octave's site script directory when libsndfile is installed (except on Win32) ie when libsndfile is being installed into /usr/local, the Octave scripts will be installed in /usr/local/share/octave/site/m/.

There are some other Octave scripts for audio to be found here.

Libsndfile is a C library for reading and writing files containing sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format) through one standard library interface. It is released in source code format under the Gnu Lesser General Public License.

The library was written to compile and run on a Linux system but should compile and run on just about any Unix (including MacOS X). There are also pre-compiled binaries available for 32 and 64 bit windows.

It was designed to handle both little-endian (such as WAV) and big-endian (such as AIFF) data, and to compile and run correctly on little-endian (such as Intel and DEC/Compaq Alpha) processor systems as well as big-endian processor systems such as Motorola 68k, Power PC, MIPS and Sparc. Hopefully the design of the library will also make it easy to extend for reading and writing new sound file formats.

It has been compiled and tested (at one time or another) on the following systems:

  • Every platform supported by Debian GNU/Linux including x86_64-linux-gnu, i486-linux-gnu, powerpc-linux-gnu, sparc-linux-gnu, alpha-linux-gnu, mips-linux-gnu and armel-linux-gnu.
  • powerpc-apple-darwin7.0 (Mac OS X 10.3)
  • sparc-sun-solaris2.8 (using gcc)
  • mips-sgi-irix5.3 (using gcc)
  • QNX 6.0
  • i386-unknown-openbsd2.9

At the moment, each new release is being tested on i386 Linux, x86_64 Linux, PowerPC Linux, Win32 and Win64.

Features

libsndfile has the following main features :

  • Ability to read and write a large number of file formats.
  • A simple, elegant and easy to use Applications Programming Interface.
  • Usable on Unix, Win32, MacOS and others.
  • On the fly format conversion, including endian-ness swapping, type conversion and bitwidth scaling.
  • Optional normalisation when reading floating point data from files containing integer data.
  • Ability to open files in read/write mode.
  • The ability to write the file header without closing the file (only on files open for write or read/write).
  • Ability to query the library about all supported formats and retrieve text strings describing each format.

libsndfile has a comprehensive test suite so that each release is as bug free as possible. When new bugs are found, new tests are added to the test suite to ensure that these bugs don't creep back into the code. When new features are added, tests are added to the test suite to make sure that these features continue to work correctly even when they are old features.

The following table lists the file formats and encodings that libsndfile can read and write. The file formats are arranged across the top and encodings along the left edge.

From version 1.0.18, libsndfile also reads and writes FLAC and Ogg/Vorbis.

Some of the file formats I am also interested in adding are:

  • Kurzweil K2000 sampler files.
  • Ogg Speex.

I have decided that I will not be adding support for MPEG Layer 3 (commonly known as MP3) due to the patent issues surrounding this file format. See the FAQ for more.

Other file formats may also be added on request.

History

My first attempt at reading and writing WAV files was in 1990 or so under Windows 3.1. I started using Linux in early 1995 and contributed some code to the wavplay program. That contributed code would eventually mutate into this library. As one of my interests is Digital Signal Processing (DSP) I decided that as well as reading data from an audio file in the native format (typically 16 bit short integers) it would also be useful to be able to have the library do the conversion to floating point numbers for DSP applications. It then dawned on me that whatever file format (anything from 8 bit unsigned chars, to 32 bit floating point numbers) the library should be able to convert the data to whatever format the library user wishes to use it in. For example, in a sound playback program, the library caller typically wants the sound data in 16 bit short integers to dump into a sound card even though the data in the file may be 32 bit floating point numbers (ie Microsoft's WAVE_FORMAT_IEEE_FLOAT format). Another example would be someone doing speech recognition research who has recorded some speech as a 16 bit WAV file but wants to process it as double precision floating point numbers.

Licensing

libsndfile is released under the terms of the GNU Lesser General Public License, of which there are two versions; version 2.1 and version 3. To maximise the compatibility of libsndfile, the user may choose to use libsndfile under either of the above two licenses. You can also read a simple explanation of the ideas behind the GPL and the LGPL here.

You can use libsndfile with Free Software, Open Source, proprietary, shareware or other closed source applications as long as libsndfile is used as a dynamically loaded library and you abide by a small number of other conditions (read the LGPL for more info). With applications released under the GNU GPL you can also use libsndfile statically linked to your application.

I would like to see libsndfile used as widely as possible but I would prefer it if you released software that uses libsndfile as Free Software or Open Source. However, if you put in a great deal of effort building a significant application which simply uses libsndfile for file I/O, then I have no problem with you releasing that as closed source and charging as much money as you want for it as long as you abide by the license.

Download

Here is the latest version. It is available in the following formats:

The GPG signature can be validated at Keybase.IO.

The Win32 installer should work on Windows Vista or later.

Pre-release versions of libsndfile are available here and are announced on the libsndfile-devel mailing list.

sf_command


        int    sf_command (SNDFILE *sndfile, int cmd, void *data, int datasize) ;

This function allows the caller to retrieve information from or change aspects of the library behaviour. Examples include retrieving a string containing the library version or changing the scaling applied to floating point sample data during read and write. Most of these operations are performed on a per-file basis.

The cmd parameter is an integer identifier which is defined in <sndfile.h>. All of the valid command identifiers have names beginning with "SFC_". Data is passed to and returned from the library by use of a void pointer. The library will not read or write more than datasize bytes from the void pointer. For some calls no data is required in which case data should be NULL and datasize may be used for some other purpose.

The available commands are as follows:

SFC_GET_LIB_VERSION Retrieve the version of the library.
SFC_GET_LOG_INFO Retrieve the internal per-file operation log.
SFC_CALC_SIGNAL_MAX Calculate the measured maximum signal value.

SFC_SET_NORM_FLOAT

This command only affects data read from or written to using the floating point functions: 

	size_t    sf_read_float    (SNDFILE *sndfile, float *ptr, size_t items) ;
	size_t    sf_readf_float   (SNDFILE *sndfile, float *ptr, size_t frames) ;

	size_t    sf_write_float   (SNDFILE *sndfile, float *ptr, size_t items) ;
	size_t    sf_writef_float  (SNDFILE *sndfile, float *ptr, size_t frames) ;

Parameters: 

        sndfile  : A valid SNDFILE* pointer
        cmd      : SFC_SET_NORM_FLOAT
        data     : NULL
        datasize : SF_TRUE or SF_FALSE

For read operations setting normalisation to SF_TRUE means that the data from all subsequent reads will be be normalised to the range [-1.0, 1.0].

For write operations, setting normalisation to SF_TRUE means than all data supplied to the float write functions should be in the range [-1.0, 1.0] and will be scaled for the file format as necessary.

For both cases, setting normalisation to SF_FALSE means that no scaling will take place.

Example: 

        sf_command (sndfile, SFC_SET_NORM_FLOAT, NULL, SF_TRUE) ;

        sf_command (sndfile, SFC_SET_NORM_FLOAT, NULL, SF_FALSE) ;
Return value:
Returns the previous float normalisation mode.


SFC_SET_NORM_DOUBLE

This command only affects data read from or written to using the double precision floating point functions: 

	size_t    sf_read_double    (SNDFILE *sndfile, double *ptr, size_t items) ;
	size_t    sf_readf_double   (SNDFILE *sndfile, double *ptr, size_t frames) ;

	size_t    sf_write_double   (SNDFILE *sndfile, double *ptr, size_t items) ;
	size_t    sf_writef_double  (SNDFILE *sndfile, double *ptr, size_t frames) ;

Parameters: 

        sndfile  : A valid SNDFILE* pointer
        cmd      : SFC_SET_NORM_DOUBLE
        data     : NULL
        datasize : SF_TRUE or SF_FALSE

For read operations setting normalisation to SF_TRUE means that the data from all subsequent reads will be be normalised to the range [-1.0, 1.0].

For write operations, setting normalisation to SF_TRUE means than all data supplied to the double write functions should be in the range [-1.0, 1.0] and will be scaled for the file format as necessary.

For both cases, setting normalisation to SF_FALSE means that no scaling will take place.

Example: 

        sf_command (sndfile, SFC_SET_NORM_DOUBLE, NULL, SF_TRUE) ;

        sf_command (sndfile, SFC_SET_NORM_DOUBLE, NULL, SF_FALSE) ;

Parameters: 

        sndfile  : Not used.
        cmd      : SFC_GET_SIMPLE_FORMAT
        data     : a pointer to an  SF_FORMAT_INFO struct
        datasize : sizeof (SF_FORMAT_INFO)

            const char  *name ;
            const char  *extension ;
        } SF_FORMAT_INFO ;

When sf_command() is called with SF_GET_SIMPLE_FORMAT, the value of the format field should be the format number (ie 0 <= format <= count value obtained using SF_GET_SIMPLE_FORMAT_COUNT).

Example: 

        SF_FORMAT_INFO	format_info ;
        int             k, count ;

        sf_command (sndfile, SFC_GET_SIMPLE_FORMAT_COUNT, &count, sizeof (int)) ;

            sf_command (sndfile, SFC_GET_SIMPLE_FORMAT, &format_info, sizeof (format_info)) ;
            printf ("%08x  %s %s\n", format_info.format, format_info.name, format_info.extension) ;
            } ;
Return value:
0 on success and non-zero otherwise.
The value of the format field of the SF_FORMAT_INFO struct will be a value which can be placed in the format field of an SF_INFO struct when a file is to be opened for write.
The name field will contain a char* pointer to the name of the string, eg. "WAV (Microsoft 16 bit PCM)".

        data     : a pointer to an SF_FORMAT_INFO struct
        datasize : sizeof (SF_FORMAT_INFO)

The SF_FORMAT_INFO struct is defined in <sndfile.h> as: 

        typedef struct
        {   int         format ;
            const char  *name ;
            const char  *extension ;
        } SF_FORMAT_INFO ;

When sf_command() is called with SF_GET_FORMAT_INFO, the format field is examined and if (format & SF_FORMAT_TYPEMASK) is a valid format then the struct is filled in with information about the given major type. If (format & SF_FORMAT_TYPEMASK) is FALSE and (format & SF_FORMAT_SUBMASK) is a valid subtype format then the struct is filled in with information about the given subtype.

SFC_SET_ADD_PEAK_CHUNK

By default, WAV and AIFF files which contain floating point data (subtype SF_FORMAT_FLOAT or SF_FORMAT_DOUBLE) have a PEAK chunk. By using this command, the addition of a PEAK chunk can be turned on or off.

Note : This call must be made before any data is written to the file.

Parameters: 

        sndfile  : A valid SNDFILE* pointer
        cmd      : SFC_SET_ADD_PEAK_CHUNK
        data     : Not used (should be NULL)
        datasize : TRUE or FALSE.

Example: 

        /* Turn on the PEAK chunk. */
        sf_command (sndfile, SFC_SET_ADD_PEAK_CHUNK, NULL, SF_TRUE) ;

        /* Turn off the PEAK chunk. */
        sf_command (sndfile, SFC_SET_ADD_PEAK_CHUNK, NULL, SF_FALSE) ;
Return value:
Returns SF_TRUE if the peak chunk will be written after this call.
Returns SF_FALSE if the peak chunk will not be written after this call.


SFC_UPDATE_HEADER_NOW

The header of an audio file is normally written by libsndfile when the file is closed using sf_close().

There are however situations where large files are being generated and it would be nice to have valid data in the header before the file is complete. Using this command will update the file header to reflect the amount of data written to the file so far. Other programs opening the file for read (before any more data is written) will then read a valid sound file header.

Parameters: 

        sndfile  : A valid SNDFILE* pointer
        cmd      : SFC_UPDATE_HEADER_NOW
        data     : Not used (should be NULL)
        datasize : Not used.

Example: 

        /* Update the header now. */
        sf_command (sndfile, SFC_UPDATE_HEADER_NOW, NULL, 0) ;
Return value:
0


SFC_SET_UPDATE_HEADER_AUTO

Similar to SFC_UPDATE_HEADER_NOW but updates the header at the end of every call to the sf_write* functions.

Parameters: 

        sndfile  : A valid SNDFILE* pointer
        cmd      : SFC_UPDATE_HEADER_NOW
        data     : Not used (should be NULL)
        datasize : SF_TRUE or SF_FALSE

Example: 

        /* Turn on auto header update. */
        sf_command (sndfile, SFC_SET_UPDATE_HEADER_AUTO, NULL, SF_TRUE) ;

        /* Turn off auto header update. */
        sf_command (sndfile, SFC_SET_UPDATE_HEADER_AUTO, NULL, SF_FALSE) ;
Return value:
TRUE if auto update header is now on; FALSE otherwise.


SFC_FILE_TRUNCATE

        datasize : sizeof (sf_count_t)

Truncate the file to the number of frames specified by the sf_count_t pointed to by data. After this command, both the read and the write pointer will be at the new end of the file. This command will fail (returning non-zero) if the requested truncate position is beyond the end of the file.

Example: 

        /* Truncate the file to a length of 20 frames. */
        sf_count_t  frames = 20 ;
        sf_command (sndfile, SFC_FILE_TRUNCATE, &frames, sizeof (frames)) ;
Return value:
Zero on sucess, non-zero otherwise.

        datasize : sizeof (sf_count_t)

For a file opened as format SF_FORMAT_RAW, set the data offset to the value given by data.

Example: 

        /* Reset the data offset to 5 bytes from the start of the file. */
        sf_count_t  offset = 5 ;
        sf_command (sndfile, SFC_SET_RAW_START_OFFSET, &offset, sizeof (offset)) ;

         data     : a pointer to an SF_CUES struct
         datasize : sizeof (SF_CUES)

The SF_CUES struct is defined in <sndfile.h> as: 

    typedef struct
    {	int cue_count ;

    	struct
    	{	int32_t   indx ;

         data     : a pointer to an SF_CUES struct
         datasize : sizeof (SF_CUES)

Example: 

         SF_CUES cues ;
         sf_command (sndfile, SFC_SET_CUE, &cues, sizeof (cues)) ;
Return value:
SF_TRUE if the file header contains cue marker information for the file. SF_FALSE otherwise.


SFC_RF64_AUTO_DOWNGRADE

Enable auto downgrade from RF64 to WAV.

The EBU recomendation is that when writing RF64 files and the resulting file is less than 4Gig in size, it should be downgraded to a WAV file (WAV files have a maximum size of 4Gig). libsndfile doesn't follow the EBU recommendations exactly, , mainly because the test suite needs to be able test reading/writing RF64 files without having to generate files larger than 4 gigabytes.

Note: This command should be issued before the first bit of audio data has been written to the file. Calling this command after audio data has been written will return the current value of this setting, but will not allow it to be changed.

Parameters: 

         sndfile  : A valid SNDFILE* pointer
         cmd      : SFC_RF64_AUTO_DOWNGRADE
         data     : NULL
         datasize : SF_TRUE or SF_FALSE

Example: 

         /* Enable auto downgrade on file close. */
         sf_command (sndfile, SFC_RF64_AUTO_DOWNGRADE, NULL, SF_TRUE) ;
Return value:
Returns SF_TRUE if SFC_RF64_AUTO_DOWNGRADE is set and SF_FALSE otherwise.

Reporting Bugs in libsndfile

Before even attempting to report a bug in libsndfile please make sure you have read the Frequently Asked Questions. If you are having a problem writing code using libsndfile make sure you read the Application Programming Interface documentation.

That said, I am interested in finding and fixing all genuine bugs in libsndfile. Bugs I want to fix include any of the following problems (and probably others) :

  • Compilation problems on new platforms.
  • Errors being detected during the `make check' process.
  • Segmentation faults occuring inside libsndfile.
  • libsndfile hanging when opening a file.
  • Supported sound file types being incorrectly read or written.
  • Omissions, errors or spelling mistakes in the documentation.

When submitting a bug report you must include :

  • Your system (CPU and memory size should be enough).
  • The operating system you are using.
  • Whether you are using a package provided by your distribution or you compiled it youself.
  • If you compiled it yourself, the compiler you are using. (Also make sure to run 'make check'.)
  • A description of the problem.
  • Information generated by the sndfile-info program (see next paragraph).
  • If you are having problems with sndfile-play and ALSA on Linux, I will need information about your kernel, ALSA version, compiler version, whether you compiled the kernel/ALSA your self or installed from a package etc.

If libsndfile compiles and installs correctly but has difficulty reading a particular file or type of file you should run the sndfile-info program (from the examples directory of the libsndfile distribution) on the file. See here for an example of the use of the sndfile-info program.

Please do not send me a sound file which fails to open under libsndfile unless I specifically ask you to. The above information should usually suffice for most problems.

Once you have the above information you should submit a ticket on the libsnfile github issue tracker.

libsndfile-1.0.28/doc/api.html0000644000175000017500000007402513070135662013055 00000000000000 The libsndfile API

libsndfile

Libsndfile is a library designed to allow the reading and writing of many different sampled sound file formats (such as MS Windows WAV and the Apple/SGI AIFF format) through one standard library interface.

During read and write operations, formats are seamlessly converted between the format the application program has requested or supplied and the file's data format. The application programmer can remain blissfully unaware of issues such as file endian-ness and data format. See Note 1 and Note 2.

Every effort is made to keep these documents up-to-date, error free and unambiguous. However, since maintaining the documentation is the least fun part of working on libsndfile, these docs can and do fall behind the behaviour of the library. If any errors, omissions or ambiguities are found, please notify me (erikd) at mega-nerd dot com.

To supplement this reference documentation, there are simple example programs included in the source code tarball. The test suite which is also part of the source code tarball is also a good place to look for the correct usage of the library functions.

Finally, if you think there is some feature missing from libsndfile, check that it isn't already implemented (and documented) here.

      int         sf_set_string    (SNDFILE *sndfile, int str_type, const char* str) ;

SNDFILE* is an anonymous pointer to data which is private to the library.

File Open Function

      SNDFILE*  sf_open    (const char *path, int mode, SF_INFO *sfinfo) ;

The sf_open() function opens the sound file at the specified path. The filename is byte encoded, but may be utf-8 on Linux, while on Mac OS X it will use the filesystem character set. On Windows, there is also a Windows specific sf_wchar_open() that takes a UTF16_BE encoded filename. 

      SNDFILE*  sf_wchar_open (LPCWSTR wpath, int mode, SF_INFO *sfinfo) ;

The SF_INFO structure is for passing data between the calling function and the library when opening a file for reading or writing. It is defined in sndfile.h as follows: 

      typedef struct
      {    sf_count_t  frames ;     /* Used to be called samples. */
           int         samplerate ;
           int         channels ;
           int         format ;
           int         sections ;
           int         seekable ;
       } SF_INFO ;

The mode parameter for this function can be any one of the following three values: 

      SFM_READ    - read only mode
      SFM_WRITE   - write only mode
      SFM_RDWR    - read/write mode

When opening a file for read, the format field should be set to zero before calling sf_open(). The only exception to this is the case of RAW files where the caller has to set the samplerate, channels and format fields to valid values. All other fields of the structure are filled in by the library.

When opening a file for write, the caller must fill in structure members samplerate, channels, and format.

The format field in the above SF_INFO structure is made up of the bit-wise OR of a major format type (values between 0x10000 and 0x08000000), a minor format type (with values less than 0x10000) and an optional endian-ness value. The currently understood formats are listed in sndfile.h as follows and also include bitmasks for separating major and minor file types. Not all combinations of endian-ness and major and minor file types are valid. 

      enum
      {   /* Major formats. */
          SF_FORMAT_WAV          = 0x010000,     /* Microsoft WAV format (little endian). */
          SF_FORMAT_AIFF         = 0x020000,     /* Apple/SGI AIFF format (big endian). */
          SF_FORMAT_AU           = 0x030000,     /* Sun/NeXT AU format (big endian). */
          SF_FORMAT_RAW          = 0x040000,     /* RAW PCM data. */
          SF_FORMAT_PAF          = 0x050000,     /* Ensoniq PARIS file format. */
          SF_FORMAT_SVX          = 0x060000,     /* Amiga IFF / SVX8 / SV16 format. */
          SF_FORMAT_NIST         = 0x070000,     /* Sphere NIST format. */
          SF_FORMAT_VOC          = 0x080000,     /* VOC files. */
          SF_FORMAT_IRCAM        = 0x0A0000,     /* Berkeley/IRCAM/CARL */
          SF_FORMAT_W64          = 0x0B0000,     /* Sonic Foundry's 64 bit RIFF/WAV */

          SF_FORMAT_ENDMASK      = 0x30000000
      } ;

Every call to sf_open() should be matched with a call to sf_close() to free up memory allocated during the call to sf_open().

On success, the sf_open function returns a non-NULL pointer which should be passed as the first parameter to all subsequent libsndfile calls dealing with that audio file. On fail, the sf_open function returns a NULL pointer. An explanation of the error can obtained by passing NULL to sf_strerror.

File Descriptor Open

      SNDFILE*  sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ;

Note: On Microsoft Windows, this function does not work if the application and the libsndfile DLL are linked to different versions of the Microsoft C runtime DLL.

The second open function takes a file descriptor of a file that has already been opened. Care should be taken to ensure that the mode of the file represented by the descriptor matches the mode argument. This function is useful in the following circumstances:

  • Opening temporary files securely (ie use the tmpfile() to return a FILE* pointer and then using fileno() to retrieve the file descriptor which is then passed to libsndfile).
  • Opening files with file names using OS specific character encodings and then passing the file descriptor to sf_open_fd().
  • Opening sound files embedded within larger files. More info.

Every call to sf_open_fd() should be matched with a call to sf_close() to free up memory allocated during the call to sf_open().

When sf_close() is called, the file descriptor is only closed if the close_desc parameter was TRUE when the sf_open_fd() function was called.

On success, the sf_open_fd function returns a non-NULL pointer which should be passed as the first parameter to all subsequent libsndfile calls dealing with that audio file. On fail, the sf_open_fd function returns a NULL pointer.

Virtual File Open Function

      SNDFILE* 	sf_open_virtual	(SF_VIRTUAL_IO *sfvirtual, int mode, SF_INFO *sfinfo, void *user_data) ;

Opens a soundfile from a virtual file I/O context which is provided by the caller. This is usually used to interface libsndfile to a stream or buffer based system. Apart from the sfvirtual and the user_data parameters this function behaves like sf_open. 

      typedef struct
      {    sf_vio_get_filelen  get_filelen ;
           sf_vio_seek         seek ;
           sf_vio_read         read ;
           sf_vio_write        write ;
           sf_vio_tell         tell ;
      } SF_VIRTUAL_IO ;

Libsndfile calls the callbacks provided by the SF_VIRTUAL_IO structure when opening, reading and writing to the virtual file context. The user_data pointer is a user defined context which will be available in the callbacks. 

      typedef sf_count_t  (*sf_vio_get_filelen) (void *user_data) ;
      typedef sf_count_t  (*sf_vio_seek)        (sf_count_t offset, int whence, void *user_data) ;
      typedef sf_count_t  (*sf_vio_read)        (void *ptr, sf_count_t count, void *user_data) ;
      typedef sf_count_t  (*sf_vio_write)       (const void *ptr, sf_count_t count, void *user_data) ;
      typedef sf_count_t  (*sf_vio_tell)        (void *user_data) ;

sf_vio_get_filelen

      typedef sf_count_t  (*sf_vio_get_filelen) (void *user_data) ;

The virtual file contex must return the length of the virtual file in bytes.

sf_vio_seek

      typedef sf_count_t  (*sf_vio_seek)        (sf_count_t offset, int whence, void *user_data) ;

The virtual file context must seek to offset using the seek mode provided by whence which is one of

      SEEK_CUR
      SEEK_SET
      SEEK_END

The return value must contain the new offset in the file.

sf_vio_read

      typedef sf_count_t  (*sf_vio_read)        (void *ptr, sf_count_t count, void *user_data) ;

The virtual file context must copy ("read") "count" bytes into the buffer provided by ptr and return the count of actually copied bytes.

sf_vio_write

      typedef sf_count_t  (*sf_vio_write)       (const void *ptr, sf_count_t count, void *user_data) ;

The virtual file context must process "count" bytes stored in the buffer passed with ptr and return the count of actually processed bytes.

sf_vio_tell

      typedef sf_count_t  (*sf_vio_tell)        (void *user_data) ;

Return the current position of the virtual file context.


Format Check Function

      int  sf_format_check (const SF_INFO *info) ;

This function allows the caller to check if a set of parameters in the SF_INFO struct is valid before calling sf_open (SFM_WRITE).

sf_format_check returns TRUE if the parameters are valid and FALSE otherwise.


File Seek Functions

      sf_count_t  sf_seek  (SNDFILE *sndfile, sf_count_t frames, int whence) ;

The file seek functions work much like lseek in unistd.h with the exception that the non-audio data is ignored and the seek only moves within the audio data section of the file. In addition, seeks are defined in number of (multichannel) frames. Therefore, a seek in a stereo file from the current position forward with an offset of 1 would skip forward by one sample of both channels.

like lseek(), the whence parameter can be any one of the following three values: 

      SEEK_SET  - The offset is set to the start of the audio data plus offset (multichannel) frames.
      SEEK_CUR  - The offset is set to its current location plus offset (multichannel) frames.
      SEEK_END  - The offset is set to the end of the data plus offset (multichannel) frames.

Internally, libsndfile keeps track of the read and write locations using separate read and write pointers. If a file has been opened with a mode of SFM_RDWR, bitwise OR-ing the standard whence values above with either SFM_READ or SFM_WRITE allows the read and write pointers to be modified separately. If the SEEK_* values are used on their own, the read and write pointers are both modified.

Note that the frames offset can be negative and in fact should be when SEEK_END is used for the whence parameter.

sf_seek will return the offset in (multichannel) frames from the start of the audio data or -1 if an error occured (ie an attempt is made to seek beyond the start or end of the file).


Error Reporting Functions

      int         sf_error        (SNDFILE *sndfile) ;

This function returns the current error number for the given SNDFILE. The error number may be one of the following: 

        enum
        {   SF_ERR_NO_ERROR             = 0,
            SF_ERR_UNRECOGNISED_FORMAT  = 1,
            SF_ERR_SYSTEM               = 2,
            SF_ERR_MALFORMED_FILE       = 3,
            SF_ERR_UNSUPPORTED_ENCODING = 4
        } ;

or any one of many other internal error values. Applications should only test the return value against error values defined in <sndfile.h> as the internal error values are subject to change at any time. For errors not in the above list, the function sf_error_number() can be used to convert it to an error string. 

      const char* sf_strerror     (SNDFILE *sndfile) ;
      const char* sf_error_number (int errnum) ;

The error functions sf_strerror() and sf_error_number() convert the library's internal error enumerations into text strings. 

      int         sf_perror     (SNDFILE *sndfile) ;
      int         sf_error_str  (SNDFILE *sndfile, char* str, size_t len) ;

The functions sf_perror() and sf_error_str() are deprecated and will be dropped from the library at some later date.


File Close Function

      int  sf_close  (SNDFILE *sndfile) ;

The close function closes the file, deallocates its internal buffers and returns 0 on success or an error value otherwise.



Write Sync Function

      void  sf_write_sync  (SNDFILE *sndfile) ;

If the file is opened SFM_WRITE or SFM_RDWR, call the operating system's function to force the writing of all file cache buffers to disk. If the file is opened SFM_READ no action is taken.



File Read Functions

      sf_count_t  sf_read_short   (SNDFILE *sndfile, short *ptr, sf_count_t items) ;
      sf_count_t  sf_read_int     (SNDFILE *sndfile, int *ptr, sf_count_t items) ;
      sf_count_t  sf_read_float   (SNDFILE *sndfile, float *ptr, sf_count_t items) ;
      sf_count_t  sf_read_double  (SNDFILE *sndfile, double *ptr, sf_count_t items) ;

      sf_count_t  sf_readf_short   (SNDFILE *sndfile, short *ptr, sf_count_t frames) ;
      sf_count_t  sf_readf_int     (SNDFILE *sndfile, int *ptr, sf_count_t frames) ;
      sf_count_t  sf_readf_float   (SNDFILE *sndfile, float *ptr, sf_count_t frames) ;
      sf_count_t  sf_readf_double  (SNDFILE *sndfile, double *ptr, sf_count_t frames) ;

The file read functions fill the array pointed to by ptr with the requested number of items or frames.

For the frames-count functions, the frames parameter specifies the number of frames. A frame is just a block of samples, one for each channel. Care must be taken to ensure that there is enough space in the array pointed to by ptr, to take (frames * channels) number of items (shorts, ints, floats or doubles).

For the items-count functions, the items parameter must be an integer product of the number of channels or an error will occur. Here, an item is just a sample.

Note: The only difference between the "items" and "frames" versions of each read function is the units in which the object count is specified - calling sf_readf_short with a count argument of N, on a SNDFILE with C channels, is the same as calling sf_read_short with a count argument of N*C. The buffer pointed to by "ptr" should be the same number of bytes in each case.

Note: The data type used by the calling program and the data format of the file do not need to be the same. For instance, it is possible to open a 16 bit PCM encoded WAV file and read the data using sf_read_float(). The library seamlessly converts between the two formats on-the-fly. See Note 1.

The sf_read_XXXX and sf_readf_XXXX functions return the number of items or frames read, respectively. Unless the end of the file was reached during the read, the return value should equal the number of objects requested. Attempts to read beyond the end of the file will not result in an error but will cause the read functions to return less than the number of objects requested or 0 if already at the end of the file.


File Write Functions

      sf_count_t  sf_write_short   (SNDFILE *sndfile, short *ptr, sf_count_t items) ;
      sf_count_t  sf_write_int     (SNDFILE *sndfile, int *ptr, sf_count_t items) ;
      sf_count_t  sf_write_float   (SNDFILE *sndfile, float *ptr, sf_count_t items) ;
      sf_count_t  sf_write_double  (SNDFILE *sndfile, double *ptr, sf_count_t items) ;

      sf_count_t  sf_writef_short  (SNDFILE *sndfile, short *ptr, sf_count_t frames) ;
      sf_count_t  sf_writef_int    (SNDFILE *sndfile, int *ptr, sf_count_t frames) ;
      sf_count_t  sf_writef_float  (SNDFILE *sndfile, float *ptr, sf_count_t frames) ;
      sf_count_t  sf_writef_double (SNDFILE *sndfile, double *ptr, sf_count_t frames) ;

The file write functions write the data in the array pointed to by ptr to the file.

For items-count functions, the items parameter specifies the size of the array and must be an integer product of the number of channels or an error will occur.

For the frames-count functions, the array is expected to be large enough to hold a number of items equal to the product of frames and the number of channels.

As with the read functions above, the only difference in the items and frames version of each write function is the units in which the buffer size is specified. Again, the data type used by the calling program and the data format of the file do not need to be the same (Note 1).

The sf_write_XXXX and sf_writef_XXXX functions respectively return the number of items or frames written (which should be the same as the items or frames parameter).


Raw File Read and Write Functions

      sf_count_t  sf_read_raw     (SNDFILE *sndfile, void *ptr, sf_count_t bytes) ;
      sf_count_t  sf_write_raw    (SNDFILE *sndfile, void *ptr, sf_count_t bytes) ;

Note: Unless you are writing an external decoder/encode that uses libsndfile to handle the file headers, you should not be using these functions.

The raw read and write functions read raw audio data from the audio file (not to be confused with reading RAW header-less PCM files). The number of bytes read or written must always be an integer multiple of the number of channels multiplied by the number of bytes required to represent one sample from one channel.

The raw read and write functions return the number of bytes read or written (which should be the same as the bytes parameter).

Note : The result of using of both regular reads/writes and raw reads/writes on compressed file formats other than SF_FORMAT_ALAW and SF_FORMAT_ULAW is undefined.

Functions for Reading and Writing String Data

      const char* sf_get_string   (SNDFILE *sndfile, int str_type) ;
      int         sf_set_string   (SNDFILE *sndfile, int str_type, const char* str) ;

These functions allow strings to be set on files opened for write and to be retrieved from files opened for read where supported by the given file type. The str_type parameter can be any one of the following string types: 

          enum
          {   SF_STR_TITLE,
              SF_STR_COPYRIGHT,
              SF_STR_SOFTWARE,
              SF_STR_ARTIST,
              SF_STR_COMMENT,
              SF_STR_DATE,
              SF_STR_ALBUM,
              SF_STR_LICENSE,
              SF_STR_TRACKNUMBER,
              SF_STR_GENRE
          } ;

The sf_get_string() function returns the specified string if it exists and a NULL pointer otherwise. In addition to the string ids above, SF_STR_FIRST (== SF_STR_TITLE) and SF_STR_LAST (always the same as the highest numbers string id) are also available to allow iteration over all the available string ids.

The sf_set_string() function sets the string data. It returns zero on success and non-zero on error. The error code can be converted to a string using sf_error_number().

Strings passed to and retrieved from these two functions are assumed to be utf-8. However, while formats like Ogg/Vorbis and FLAC fully support utf-8, others like WAV and AIFF officially only support ASCII. Writing utf-8 strings to WAV and AIF files with libsndfile will work when read back with libsndfile, but may not work with other programs.

The suggested method of dealing with tags retrived using sf_get_string() is to assume they are utf-8. Similarly if you have a string in some exotic format like utf-16, it should be encoded to utf-8 before being written using libsndfile.


Note 1

When converting between integer PCM formats of differing size (e.g. using sf_read_int() to read a 16 bit PCM encoded WAV file) libsndfile obeys one simple rule:

Whenever integer data is moved from one sized container to another sized container, the most significant bit in the source container will become the most significant bit in the destination container.

When converting between integer data and floating point data, different rules apply. The default behaviour when reading floating point data (sf_read_float() or sf_read_double ()) from a file with integer data is normalisation. Regardless of whether data in the file is 8, 16, 24 or 32 bit wide, the data will be read as floating point data in the range [-1.0, 1.0]. Similarly, data in the range [-1.0, 1.0] will be written to an integer PCM file so that a data value of 1.0 will be the largest allowable integer for the given bit width. This normalisation can be turned on or off using the sf_command interface.


Note 2

Reading a file containg floating point data (allowable with WAV, AIFF, AU and other file formats) using integer read methods (sf_read_short() or sf_read_int()) can produce unexpected results. For instance the data in the file may have a maximum absolute value < 1.0 which would mean that all sample values read from the file will be zero. In order to read these files correctly using integer read methods, it is recommended that you use the sf_command interface, a command of SFC_SET_SCALE_FLOAT_INT_READ and a parameter of SF_TRUE to force correct scaling.

Building libsndfile on Win32

Note : For pre-compiled binaries for windows, both for win32 and win64, see the main web page.

There is currently only one way of building libsndfile for Win32 and Win64; cross compiling from Linux using the MinGW cross compiler.

libsndfile is written to be compiled by a compiler which supports large chunks of the 1999 ISO C Standard. Unfortunately, the microsoft compiler supports close to nothing of this standard and hence is not suitable for libsndfile.

It may be possible to compile libsndfile on windows using the MinGW compiler suite, but I haven't tested that and have no interest in supporting that.

The src/ directory contains the source code for library itself. The doc/ directory contains the libsndfile documentation. The examples/ directory contains examples of how to write code using libsndfile. The tests/ directory contains programs which link against libsndfile and test its functionality. The src/GSM610 directory contains code written by Jutta Degener and Carsten Bormann. Their original code can be found at : http://kbs.cs.tu-berlin.de/~jutta/toast.html The src/G72x directory contains code written and released by Sun Microsystems under a suitably free license. The src/ALAC directory contains code written and released by Apple Inc and released under the Apache license. LINUX ----- Whereever possible, you should use the packages supplied by your Linux distribution. If you really do need to compile from source it should be as easy as: ./configure make make install Since libsndfile optionally links against libFLAC, libogg and libvorbis, you will need to install appropriate versions of these libraries before running configure as above. UNIX ---- Compile as for Linux. Win32/Win64 ----------- The default Windows compilers are nowhere near compliant with the 1999 ISO C Standard and hence not able to compile libsndfile. Please use the libsndfile binaries available on the libsndfile web site. MacOSX ------ Building on MacOSX should be the same as building it on any other Unix.

When reading short or int data from a file containing float data, and setting SFC_SET_SCALE_FLOAT_INT_READ to SF_TRUE would fail 3, 5, 7 and other channels counts. Problem was that psf_calc_signal_max() was not calculating the signal max correctly. Calculation of the signal max was failing because it was trying to read a sample count that was not an integer multiple of the channel count. * tests/channel_test.c tests/Makefile.am tests/test_wrapper.sh.in Add test for the above. 2012-09-25 Erik de Castro Lopo * src/sndfile.hh Added a constructor to allow the use of SF_VIRTUAL_IO.

Fixes github issue #4 reported by Charles Van Winkle. * src/sfconfig.h src/sfendian.h Fix for MinGW cross compiling. Use '#if (defined __*66__)' instead of '#if __*86__' because the MinGW header use '#ifdef __x86_64__'. 2012-03-10 Erik de Castro Lopo * src/ALAC/ src/alac.c Unify the interface between libsndfile and Apple ALAC codec. Regardless of file bit width samples are now passed between the two as int32_t that are justified towards the most significant bit. Without this modification, 16 conversion functions would have been needed between the libsndfile (short, int, float, double) types and the ALAC types (16, 20, 24 and 32 bit). With this mod, only 4 are needed. * tests/floating_point_test.tpl tests/write_read_test.(def|tpl) Add tests for 20 and 24 bit ALAC/CAF files. * src/command.c Add ALAC/CAF to the SFC_GET_FORMAT_* commands. Fixes github issue #5. * configure.ac Only use automake AM_SLIENT_RULES where supported. Thanks Dave Yeo. * tests/pipe_test.tpl Disable tests on OS/2. Thanks Dave Yeo. 2012-03-09 Erik de Castro Lopo * configure.ac src/sfconfig.h src/sfendian.h For GCC, use inline assembler for endian swapping.

The copyyright to this code is owned by Apple who have released it under an Apache style license. A few small modifications were made to allow this to be integrated into libsndfile but unfortunately the history of those changes were lost because they were developed in a Bzr tree and during that time libsndfile moved to Git. * src/alac.c src/caf.c src/common.[ch] src/Makefile.am src/sndfile.h.in src/sndfile.c Hook new ALAC codec in. * programs/sndfile-convert.c Add support for alac codec. * tests/write_read_test.tpl Expand tests to cover ALAC. 2012-03-02 Erik de Castro Lopo * src/aiff.c src/wav.c Fix a couple of regressions from version 1.0.25. 2012-03-01 Erik de Castro Lopo * src/strings.c Minor refactoring. Make sure that the memory allocation size if always > 0 to avoid undefined behaviour. 2012-02-29 Erik de Castro Lopo * src/chunk.c Fix buffer overrun introduced in recently added chunk logging. This chunk logging has not yet made it to a libsndfile release version. Thanks to Olivier Tristan for providing an example file. * src/wav.c Fix handling of odd sized chunks which was causing the parser to lose some chunks. Thanks to Olivier Tristan for providing an example file. 2012-02-26 Erik de Castro Lopo * tests/util.tpl Used gnu_printf format checking with mingw-w64 compiler. * tests/header_test.tpl Printf format fixes. 2012-02-25 Erik de Castro Lopo * M4/extra_pkg.m4 Update PKG_CHECK_MOD_VERSION macro to add an AC_TRY_LINK step. This fix allows the configure process to catch attempts to link incompatible libraries. For example, linking 32 bit version of eg libFLAC to a 64 bit version of libsndfile will now fail. Similarly, when cross compiling libsndfile from Linux to Windows linking the Linux versions of a library to the Windows version of libsndfile will now also fail. * src/sndfile.h.in src/sndfile.c src/common.h src/create_symbols_file.py Add API function sf_current_byterate(). * src/dwvw.c src/flac.c src/ogg_vorbis.c src/sds.c Add codec specific handlers for current byterate. * tests/floating_point_test.tpl Add initial test for sf_current_byterate(). 2012-02-24 Erik de Castro Lopo * src/common.[ch] Add function psf_decode_frame_count(). * src/dwvw.c Fix a termnation bug that caused the decoder to go into an infinite loop. 2012-02-24 Erik de Castro Lopo * src/wav.c Fix a regression in the WAV header parser. Thanks to Olivier Tristan for bug report and the example file. 2012-02-21 Erik de Castro Lopo * src/sndfile.c Return error when SF_BROADCAST_INFO struct has bad coding_history_size.

Also add support for writing Win32 .def files. The Python script generates Symbols.linux, Symbols.darwin and libsndfile.def (Win32 version). These files get shipped with the tarball so there should not be necessary to run the Python script when building the code from the tarball. * configure.ac src/Makefile.am Win32/Makefile.am Hook new Python script into the build system. 2004-02-25 Erik de Castro Lopo * src/configure.ac Add --enable-gcc-werror option and move GCC specific stuff down. 2004-02-24 Erik de Castro Lopo * acinclude.m4 configure.ac Fix clip mode detection (tested in one of HP's testdrive Itanium II boxes). * src/file_io.c Added check for sizeof (off_t) != sizeof (sf_count_t) to prevent recurrence of missing large file support on Linux and Solaris. 2004-02-19 Erik de Castro Lopo * examples/sndfile-play.c Fix a MacOSX specific bug which was caused by a space being inserted in the middle of a file name. * configure.ac src/Makefile.am examples/Makefile.am Fix a couple of MacOSX build issues. 2004-02-17 Erik de Castro Lopo * doc/command.html Document SFC_SET_CLIPPING and SFC_GET_CLIPPING. 2004-02-14 Erik de Castro Lopo * doc/*.html Applied patch from Frank Neumann (author of lakai) which fixes many minor typos in documentation. Thanks Frank. 2004-02-13 Erik de Castro Lopo * ChangeLog Changed my email address throughout source and docs. 2004-02-08 Erik de Castro Lopo * src/file_io.c Make sure config.h is included before stdio.h to make sure large file support is enabled on Linux (and Solaris). * tests/misc_test.c Disable update_header test on Win32. This should work but doesn't and I'm not sure why. * Make.bat Win32/Makefile.msvc Updates. 2004-01-07 Erik de Castro Lopo * src/common.h Changed logindex, headindex and headend files of SF_PRIVATE from unsigned int to int to prevent weird arithmetic bugs. * src/common.c src/aiff.c src/wav.c src/w64.c Fixed compiler warnings resulting from above change. 2004-01-06 Erik de Castro Lopo * src/common.c Fixed a bug in header reader for some files with data after the sample data. 2003-12-29 Erik de Castro Lopo * tests/lossy_comp_test.c tests/Makefile.am Add tests for AIFF/IMA files. 2003-12-26 Erik de Castro Lopo * src/macbinary3.c src/macos.c Two new files required for handling SD2 files. * src/common.h Add prototypes for functions in above two files. * src/Makefile.am Hook new files into build system. 2003-12-21 Erik de Castro Lopo * configure.ac Add checks for mmap() and getpagesize() which might be used at some time for faster file reads. Add detection of MacOSX. 2003-12-13 Erik de Castro Lopo * doc/FAQ.html Minor mods to pkg-config section. 2003-12-12 Erik de Castro Lopo * src/create_symbols_file.sh Andre Pang (also known as Ozone) pointed out that on MacOSX, all non static symbols are exported causing troubles when trying to link libsndfile with another library which has any of the same symbols. He fixed this by supplying the MacOSX linker with a file containing all the public symbols so that only they would be exported and then supplied a patch for libsndfile. This wasn't quite ideal, because I would have to maintain two (3 if you include Win32) separate files containing the exported symbols. A better solution was to create this script which can generate a Symbols file for Linux, MacoSX and any other OS that supports minimising the number of exported symbols. * configure.ac src/Makefile.am Hook the new script into the build process. 2003-12-10 Erik de Castro Lopo * doc/index.html Added comments about Steve Dekorte's SoundConverter scam. 2003-12-07 Erik de Castro Lopo * src/file_io.c Axel Röbel pointed out that on Mac OSX a pipe is not considered a fifo (S_ISFIFO (st.st_mode) is false) but a socket (S_ISSOCK (st.st_mode) is true). The test has therefore been changed to is S_ISREG and anything which which does not return true for S_ISREG is considered a pipe. 2003-11-25 Erik de Castro Lopo * tests/misc_test.c Fix update_header_test to pass SDS. * src/sds.c More minor fixes. * tests/floating_point_test.c Add test for SDS files. * src/command.c Add SDS to major_formats array. 2003-11-24 Erik de Castro Lopo * tests/write_read_test.tpl tests/misc_test.c Add tests for SDS files. * src/sds.c Fix a bug in header update code. 2003-11-23 Erik de Castro Lopo * src/sds.c Get file write working. * src/paf.c Fix a potential bug in paf24_seek(). 2003-11-04 Erik de Castro Lopo * doc/FAQ.html Add Q/A about u-law encoded WAV files. * Win32/*.h Updated so it compiles on Win32. 2003-11-03 Erik de Castro Lopo * examples/sndfile-convert.c Add -alaw and -ulaw command line arguments. * configure.ac Add library versioning comments. Add arguments to AC_INIT. 2003-10-28 Erik de Castro Lopo * src/file_io.c Ross Bencina has contributed code to replace all of the (mostly broken) Win32 POSIX emulation calls with calls the native Win32 file I/O API. This code still needs testing but is likely to be a huge improvemnt of support for Win32. Thanks Ross. 2003-10-27 Erik de Castro Lopo * src/dwvw.c Removed filedes field from the DWVW_PRIVATE struct. * src/file_io.c Change psf_fopen() so it returns psf->error instead of the file descriptor. Add new functions psf_set_stdio() and psf_set_file(). * src/sndfile.c Change these to work with changed psf_fopen() return value. Remove all uses of psf->filedes from sndfile, making it easier to slot native Win32 API file handling functions. * src/test_file_io.c Minor changes to make it compile with new file_io.c stuff. 2003-10-26 Erik de Castro Lopo * src/gsm610.h Rename a variable from true to true_flag. As Ross Bencina points out, true is defined in the C99 header . * src/file_io.c If fstat() fails, return SF_TRUE instead of -1 (Ross Bencina). 2003-10-09 Erik de Castro Lopo * src/common.h Increase the size of SF_BUFFER_LEN and SF_HEADER_LEN. * src/sndfile.c Fix sf_read/write_raw which were dividing by psf->bytwidth and psf->blockwidth which can both be zero. * examples/sndfile-info.c Increase size of BUFFER_LEN. 2003-09-21 Erik de Castro Lopo * configure.ac Add checks for and ssize_t. Other Win32/MinGW checks. * src/aiff.c src/au_g72x.c src/file_io.c src/gsm610.c src/interleave.c src/paf.c src/sds.c src/svx.c src/voc.c src/w64.c src/wav.c src/xi.c Fix compiler warnings. 2003-09-20 Erik de Castro Lopo * tests/scale_clip_test.tpl Add definition of M_PI if needed. 2003-09-19 Erik de Castro Lopo * configure.ac Detect if S_IRGRP is declared in . * src/file_io.c tests/*.tpl tests/*.c More fixes for Win32/MSVC++ and MinGW. MinGW does have but that file doesn't declare S_IRGRP. 2003-10-18 Erik de Castro Lopo * src/config.h.in Add comment stating that the sf_count_t typedef is determined when libsndfile is being compiled. * tests/utils.tpl Modified so that utils.c gets one copy of the GPL and not two. 2003-09-17 Erik de Castro Lopo * Win32/unistd.h src/sf_unistd.h Move first file to the second. This will help for Win32/MSVC++ and MinGW. * Win32/Makefile.am src/Makefile.am Changed in line with above. * Win32/Makefile.msvc Removed "/I Win32" which is no longer required. * src/file_io.c src/test_file_io.c tests/*.tpl tests/*.c If HAVE_UNISTD_H include else include . This should work for Win32, MinGW and other fakes Unix-like OSes. * src/*.c Removed #include from files which didn't need it. 2003-09-16 Erik de Castro Lopo * libsndfile.spec.in Apply fix from Andrew Schultz. 2003-09-07 Erik de Castro Lopo * src/vox_adpcm.c Only set psf->sf.samplerate if the existing value is invalid. 2003-09-06 Erik de Castro Lopo * examples/sndfile-play.c Started adding support for ALSA output. 2003-09-04 Erik de Castro Lopo * src/sndfile.h.in Removed from sndfile.h. * src/*.c examples/*.c tests/*.c tests/*.tpl Added where needed. 2003-09-02 Erik de Castro Lopo * src/common.h Added ARRAY_LEN, SF_MAX and SF_MIN macros. 2003-08-19 Erik de Castro Lopo * doc/index.html Remove statements about alternative licensing arrangements. 2003-08-17 Erik de Castro Lopo * MacOS MacOS9 Makefile.am configure.ac Change directory name from MacOS to MacOS9 * MacOS9/MacOS9-readme.txt Change name to make it really obvious, add text to top of file to make it still more obvious again. 2003-08-16 Erik de Castro Lopo * src/test_log_printf.c Add tests for %u conversions. * src/common.c Fix psf_log_printf() %u conversions. 2003-08-15 Erik de Castro Lopo * src/aiff.c Fixed a bug where opening a file with a non-trival header in SFM_RDWR mode would over-write part of the header. Thanks to Axel Röbel for pointing this out. Axel also provided a patch to fix this but I came up with a neater and more general solution. Return error when openning an AIFF file with data after the SSND chunk (Thanks Axel Röbel). * tests/aiff_rw_test.c Improvements to test program which will later allow it to be generalised to test WAV, SVX and others as required. 2003-08-14 Erik de Castro Lopo * tests/pipe_test.c Add useek_pipe_rw_test() submitted by Russell Francis. * src/sndfile.c In sf_open_fd(), check if input file descriptor is a pipe. * src/sndfile.[ch] Fix typo in variable name do_not_close_descriptor. 2003-08-13 Erik de Castro Lopo * src/test_log_printf.c Improve the tests for %d and %s conversions. * src/common.c Fixed a few problems in psf_log_printf() found using new tests. 2003-08-06 Erik de Castro Lopo * configure.ac Add -Wwrite-strings warning to CFLAGS if the compiler is GCC.

Still incomplete. 2003-06-29 Erik de Castro Lopo * src/sndfile.c Fix VALIDATE_SNDFILE_AND_ASSIGN_PSF which was returning an error rather than saving it and returning zero. 2003-06-25 Erik de Castro Lopo * src/file_io.c Two fixes for Mac OS9. Fix all casts from sf_count_t to ssize_t (not size_t). 2003-06-22 Erik de Castro Lopo * src/wav.c Fix for reading files with RIFF length of 8 and data length of 0. 2003-06-14 Erik de Castro Lopo * src/*.c tests/*.c tests/*.tpl Added comments to mark code for removal when make Lite version of libsndfile. 2003-06-09 Erik de Castro Lopo * examples/sndfile-convert.c Add extra error checking for unrecognised arguments. 2003-06-08 Erik de Castro Lopo * src/ima_adpcm.c Started adding code to write IMA ADPCM encoded AIFF files. * src/test_log_printf.c src/Makefile.am New file to test psf_log_printf() function and add hooks into build system. * src/common.c Move psf_log_printf() function to top of the file and only compile the rest of the file if if PSF_LOG_PRINTF_ONLY is not defined. 2003-06-03 Erik de Castro Lopo * Win32/config.h Win32/sndfile.h Updated with new config variables. * Win32/unistd.h src/file_io.c Added implementation of S_ISFIFO macro which Win32 seems to lack and is used in src/file_io.c. * tests/utils.tpl Added #include to pull in Win32/unistd.h so it compiles for Win32. * src/Makefile.msvc Added src\test_file_io.exe build target and run this as the very first test. * tests/win32_test.c Add support for testing Cygwin32. * configure.ac Detect POSIX fsync() and fdatasync() functions. * src/file_io.c If compiling for Cygwin, call fsync() before calling fstat() to retrieve file length. * tests/pcm_test.tpl Add a test for lrintf() function. This was required to detect a really broken lrint() and lrintf() on Cygwin. * tests/misc_test.c Don't run permission test when compiling under Cygwin. * src/float_cast.h Fix fallback macro for lrint() and lrintf() to cast to long instead of int to match official function prototypes. 2003-06-02 Erik de Castro Lopo * examples/sndfile-convert.c Modifications to improve accuracy of conversions; use double data for floating point and int for everything else. * src/ima_apdcm.c Completed work on decoding IMA ADPCM encoded AIFF files. Still need to get encoding working. 2003-05-28 Erik de Castro Lopo * src/aiff.c src/ima_adpcm.c Start working on getting IMA ADPCM encoded AIFF files working. 2003-05-27 Erik de Castro Lopo * configure.ac Fixed the touch command for when the autogen program is not found (Matt Flax). * src/ulaw.c src/alaw.c Made these pipe-able. 2003-05-24 Erik de Castro Lopo * src/paf.c src/ircam.c Fixed writing to pipe. * src/wav.c src/aiff.c src/nist.c src/mat*.c src/svx.c src/w64.c Return SFE_NO_PIPE_WRITE if an attempt is made to write to a pipe. 2003-05-23 Erik de Castro Lopo * examples/sndfile-info.c Modified to detect unknown file lengths. * src/mat4.c Fix reading from a pipe. 2003-05-22 Erik de Castro Lopo * tests/pipe_test.c Add more file types to tests. * src/mat4.c Removed explicit setting of psf->sf.seekable to SF_TRUE. * tests/utils.tpl Add macro for generating and check data in the stdio and pipe tests. * tests/stdout_test.c tests/stdin_test.c Use the above macro to generate known data on output and check data on input. * src/voc.c src/htk.c common.h sndfile.c Disallow reading/writing VOC and HTK files from/to pipes be returning new error values. * src/w64.c Fixes to allow reading from a pipe. 2003-05-21 Erik de Castro Lopo * configure.ac src/sndfile.h.in When the configure script determines the sizeof (sf_count_t), also set the value of SF_COUNT_MAX in sndfile.h. * configure.ac Remove -pedantic flag from default GCC compiler flags. * tests/pipe_test.c Add a pipe_read_test() before doing pipe_write_test(). * tests/scale_clip_test.c Add test to make sure non-normalized values also clip in the right way. 2003-05-18 Erik de Castro Lopo * configure.ac Add test to detect processor clipping capabilities. * tests/stdin_test.c tests/stdout_test.c Fix a pair of compiler warnings. * src/common.h Add new pipeoffset field to SF_PRIVATE. This will contain the current file offset when operating on a pipe. * src/common.c Removed direct calls to psf_fread()/psf_fseek()/psf_fgets() etc from psf_binheader_readf and redirect them to new buffered versions header_read(), header_seek() and header_gets(). Add "G" format specifier to emulate fgets() functionality with buffering. This will allow reading some file types from pipes. * src/file_io.c When the file descriptor is a pipe, manintain psf->pipeoffset. * src/pvf.c Change use of psf_fgets() to psf_binheader_readf() as required but changes to header re * src/au.c Fix reading from a pipe. 2003-05-17 Erik de Castro Lopo * src/pcm.c Add clipping versions of the f2XXX_array() functions to allow option of clipping data that would otherwise overflow. * tests/scale_clip_test.tpl tests/scale_clip_test.def New files test that clipping option does actually work. 2003-05-14 Erik de Castro Lopo * doc/index.html Fixed a typo ("OS(" instead of "OS9"). 2003-05-13 Erik de Castro Lopo * tests/open_fail_test.c Include to prevent warning message of missing declaration of memset(). 2003-05-12 Erik de Castro Lopo * src/common.h Add new "add_clipping" field to SF_PRIVATE. * src/sndfile.h.in src/sndfile.c Add command SFC_SET_CLIPPING which sets/resets add_clipping field. 2003-05-11 Erik de Castro Lopo * doc/api.html Add docs for sf_set_string() and sf_get_string(). * src/common.h src/sndfile.c Add new SFE_STR_BAD_STRING error. * tests/stdin_test.c tests/stdout_test.c Removed all non-error print statements. * tests/stdio_test.c tests/pipe_test.c tests/Makefile.am Add print statements removed from two files above. 2003-05-10 Erik de Castro Lopo * libsndfile.spec.in Fixed a coulpe of minor errors discovered by someone calling themselves Agent Smith. * src/common.c src/common.h src/file_io.h Added is_pipe field to SF_PRIVATE and declaration of psf_is_pipe() function.

(Axel Röbel) * tests/pipe_test.c Mods to make this test work and actually do the test on RAW files. (Axel Röbel). 2003-05-05 Erik de Castro Lopo * src/sndfile.c Fixed a potential bug where psf->sf.seekable was being set to FALSE when operating on stdin or stdout but then the default initialiser was reseting it to TRUE. Thanks to Axel Röbel. * src/aiff.c Fixed a bug in the header parser where it was not handling an odd length COMM chunk correctly. Thanks to Axel Röbel. * src/test_file_io.c Add more tests. * tests/win32_test.c New file for showing the bugs in the Win32 implementation of the POSIX API. It also runs on Linux for sanity checking. * tests/Makefile.am Win32/Makefile.msvc Hook the new test program into the build system. 2003-05-04 Erik de Castro Lopo * src/test_file_io.c New test program to test operation of functions defined in file_io.c. This should make supporting win32 significantly easier. * src/Makefile.am Hook new test program into the build system. * src/file_io.c Add compile/run time check that sizeof statbuf.st_size and sf_count_t are the same. * src/common.h src/sndfile.c Added new error code and error message for new check. * tests/benchmark.tpl Fix to use frames instead of samples in SF_INFO. 2003-05-03 Erik de Castro Lopo * src/file_io.c More stuffing about working around PLAIN OLD-FASHIONED **BUGS** in Win32. * examples/sndfile-info.c Applied patch from Conrad Parker to add "--help" and "-h" options as well as an improved usage message. 2003-05-02 Erik de Castro Lopo * src/au.c Added embedded file support. * tests/multi_file_test.c Added tests for embedded AU files. Added verbose testing mode. * src/common.h src/sndfile.c Added an embedded AU specific error code and message. * src/wav.c Added patch from Conrad Parker which filled in a little more information about ACIDized WAV files. 2003-04-30 Erik de Castro Lopo * src/file_io.c Fixed Win32 version of psf_fseek() which was calling psf_get_filelen() which was in turn calling psf_fseek() which in the end blew the stack. Now of course this would have been easy to find on Linux, but this blow up was happening in kernel32.dll and the fscking MSVC++ debugger couldn't figure out what call caused this (it couldn't even tell me the stack had overflowed) and was absolutley useless for this debugging exercise. On top of that, the reason I got into this mess was that windoze doesn't have a working fstat() function which can return file lengths > 2 Gig. It HAS a fscking _fstati64() but the file length value is only updated AFTER the bloody file is closed. That makes it completely useless. How the hell do people stand working on this crap excuse of an OS? 2003-04-29 Erik de Castro Lopo * Win32/unistd.h src/file_io.c Moved definitions of S_IGRP etc from file_io.c to unistd.h so that these can be used in the test programs. * Win32/libsndfile.def Added sf_open_fd. * Win32/sndfile.h Updated to match src/sndfile.h.in. * Win32/Makefile.msvc Added dither.c and htk.c to libsndfile.dll target. 2003-04-28 Erik de Castro Lopo * src/file_io.c First attempt at getting the Win32 versions of the these functions working. They still need to be tested. 2003-04-27 Erik de Castro Lopo * src/strings.c Found and fixed a bug which was causing psf_store_string() to fail on Motorola 68k processors. Many thanks to Joshua Haberman (Debian maintainer of libsndfile) for compiling and running debug code to help me debug the problem. 2003-04-26 Erik de Castro Lopo * src/sndfile.c src/file_io.c src/wav.c src/aiff.c Much hacking to get reading and writing of embedded files working (ie sound files at a non-zero files offset). * doc/embedded_files.html First pass atempt at documenting reading/writing embedded files. 2003-04-21 Erik de Castro Lopo * doc/FAQ.html Updated answer to "Why doesn't libsndfile do interleaving/de-interleaving?" 2003-04-19 Erik de Castro Lopo * src/wav.c src/aiff.c Fix retrieving and storing of string data from files. Need to be careful about using psf->buffer for strings. 2003-04-18 Erik de Castro Lopo * src/file_io.c Fix psf_fseek() for seeks withing embedded files. 2003-04-15 Erik de Castro Lopo * src/sndfile.h.in Changed the definition of SNDFILE slightly to produce warnings when it isn't used correctly. This should have zero affect in code which uses the SNDFILE type correctly. * src/sndfile.c Fixed a few compiler warnings cause by the changes to the SNDFILE type. 2003-04-12 Erik de Castro Lopo * doc/FAQ.html Added question and answer to the question "How about adding the ability to write/read sound files to/from memory buffers?". 2003-04-08 Erik de Castro Lopo * tests/write_read_test.tpl Removed un-needed enums declaring TRUE and FALSE and replaced usage of these with SF_TRUE and SF_FALSE. * tests/multi_file_test.c New test program to test sf_open_fd() on files containing data other than a single sound file. 2003-04-06 Erik de Castro Lopo * src/file_io.c When creating files, set the readable by others flag. This still allows further restrictions to be enforced by use of the user's umask. Fix suggested by Eric Lyon. 2003-04-05 Erik de Castro Lopo * src/sndfile.h.in src/sndfile.c Changed sf_open_fd(). Dropped offset parameter and added a close_desc parameter. If close desc is TRUE, the file descritpor passed into the library will be closed when sf_close() is called. * tests/utils.tpl Modified call to sf_open_fd() to set close_desc parameter to SF_TRUE. 2003-04-04 Erik de Castro Lopo * tests/write_read_test.tpl Add a string (using sf_set_string() function) before and after data section of all files. This will make sure that if string data can be added, it doesn't overwrite real audio data. 2003-04-02 Erik de Castro Lopo * src/sndfile.c Started work on supporting a non-zero offset parameter for sf_open_fd (). * src/.c Removed many uses of psf_fseek (SEEK_END) which to allow for future use of sf_open_fd() with non-zero offset. Associated refactoring. * src/aiff.c Implemented functionality required to get sf_get_string() and sf_set_string() working for AIFF files. 2003-04-01 Erik de Castro Lopo * tests/utils.tpl Modified test_open_file_or_die() to alternately use sf_open() and sf_open_fd(). * src/svx.c Fixed a bug which occurred when openning an existing file for read/write using sf_open_fd(). In this case, the existing NAME chunk needs to be read into psf->filename. Fixed printing of sf_count_t types to logbuffer. 2003-03-31 Erik de Castro Lopo * src/sndfile.h.in Added prototype for new function sf_open_fd(). * src/sndfile.c Moved most of the code in sf_open() to a new function psf_open_file(). Created new function sf_open_fd() which also uses psf_open_file() but does not currently support the offset parameter. * doc/api.html Document sf_open_fd(). 2003-03-09 Erik de Castro Lopo * src/sndfile.c Fixed a memory leak reported by Evgeny Karpov. Memory leak only occurred when an attempt was made to read and the open() call fails. 2003-03-08 Erik de Castro Lopo * tests/open_fail_test.c New test program to check for memory leaks when sf_open fails on a valid file. Currently this must be run manually under valgrid. * tests/Makefile.am Hook new test program into build. 2003-03-03 Erik de Castro Lopo * Octave/sndfile_save.m Octave/sndfile_play.m Added a -mat-binary option to the octave save command to force the output to binary mode even if the user has set ascii data as the default. Found by Christopher Moore. 2003-02-27 Erik de Castro Lopo * doc/dither.html New file which will document the interface which allows the addition of audio dither when sample word sizes are being reduced. * src/dither.c More work. 2003-02-26 Erik de Castro Lopo * tests/misc_test.c In update_header_test(), make HTK files a special case. * doc/index.html Added HTK to the feature matrix. 2003-02-25 Erik de Castro Lopo * src/htk.c New file for reading/writing HMM Tool Kit files. * src/sndfile.h.in src/sndfile.c src/command.c src/Makefile.am Hook in htk.c * tests/write_read_test.tpl tests/misc_test.c tests/Makefile.am Add tests for HTK files. 2003-02-22 Erik de Castro Lopo * src/wav.c Fixed a bug where the LIST chunk length was being written incorrectly. * tests/string_test.c Added call to check_log_buffer(). Minor cleanups. 2003-02-10 Erik de Castro Lopo * src/wav_w64.h Applied patch from Antoine Mathys to add extra WAV format definitions and a G72x_ADPCM_WAV_FMT struct definition. * src/wav_w64.c Applied patch from Antoine Mathys which converts wav_w64_format_str() from one huge inefficient switch statement to a binary search. * tests/string_test.c Dump log buffer if tests fail. 2003-02-07 Erik de Castro Lopo * tests/string_test.c David Viens supplied some modifications to this file which showed up a bug when using sf_set_string() and the sf_writef_float() functions. * src/sndfile.c Fixed the above bug. 2003-02-06 Erik de Castro Lopo * doc/FAQ.html Added Q and A on how to detect libsndfile in configure.in (at the suggestion of Davy Durham). 2003-02-05 Erik de Castro Lopo * src/sndfile.h.in Add enums and typedefs for dither. Deprecate SFC_SET_ADD_DITHER_ON_WRITE and SFC_SET_ADD_DITHER_ON_READ, to be replaced with SFC_SET_DITHER_ON_WRITE and SFC_SET_DITHER_ON_READ which will allow different dither algorithms to be enabled. Added SFC_GET_DITHER_INFO_COUNT and SFC_GET_DITHER_INFO. * src/sndfile.h.in src/Version_script.in Win32/libsndfile.def. Added public sf_dither_*() functions. * src/sndfile.c Implement commands above. * src/dither.c More work. Framework and external hooks into dither algorithms complete. 2003-02-03 Erik de Castro Lopo * doc/version-1.html libsndfile_version_convert.py Remove redundant files. * doc/index.html doc/api.html Remove links to version-1.html. * src/dither.c New file to allow the addition of audio dither on input and output. * src/common.h Add prototype for dither_init() function. * Makefile.am doc/Makefile.am Changes for added and removed files. 2003-02-02 Erik de Castro Lopo * Win32/Makefile.msvc Changes to force example binaries to be placed in the top level directory instead of the examples/ directory. Add src/strings.c and src/xi.c to the build. Add string_test to build and to tests on WAV files. * doc/index.html Added XI to support matrix. 2003-01-27 Erik de Castro Lopo * src/sndfile.h.in Added prototypes for sf_get_string() and sf_set_string() and SF_STR_* enum values. * src/sndfile.c Added public interface to sf_get_string() and sf_set_string(). * src/wav.c Added code for setting and getting strings in WAV files. * tests/string_test.c New test program for sf_get_string() and sf_set_string() functionality. * tests/Makefile.am Hook new test program into build and test framework. 2003-01-26 Erik de Castro Lopo * src/common.h Added fields to SF_PRIVATE for string data needed to implement sf_get_string() and sf_set_string(). * src/strings.c New file for storing and retrieving strings to/from files. * src/Makefile.am Added strings.c to build. 2003-01-25 Erik de Castro Lopo * src/xi.c Read seems to be working so looking at write. * src/sndfile.h.in Added SF_FORMAT_XI, SF_FORMAT_DPCM_8 and SF_FORMAT_DPCM_16 enum values. * tests/floating_point_test.c tests/lossy_comp_test.c tests/Makefile.am Added test for 8 and 16 bit XI format files. 2003-01-24 Erik de Castro Lopo * doc/index.html Added a non-lawyer readable summary of the licensing provisions as suggested by Steve Dekorte. 2003-01-23 Erik de Castro Lopo * src/wav.c Fixed a compiler warning found by Alexander Lerch. 2003-01-18 Erik de Castro Lopo * configure.ac Fixed the multiple linking of libm. 2003-01-17 Erik de Castro Lopo * Win32/Makefile.mcvs Added comments on the correct way to set up the MSVCDir environment variable. * doc/win32.html Add on how to set up the MSVCDir environment variable. 2003-01-15 Erik de Castro Lopo * examples/sndfile-play.c examples/sndfile-info.c When run on Win32 without any command line parameters print a message and then sleep for 5 seconds. This means the when somebody double clicks on these programs in explorer the user will actually see the message. 2003-01-14 Erik de Castro Lopo * tests/misc_test.c Bypass permission test if running as root because root is allowed to open a readonly file for write. 2003-01-08 Erik de Castro Lopo * Win32/Makefile.msvc Added pvf.c and xi.c source files to project. * src/sndfile.h Updated for PVF files. 2003-01-07 Erik de Castro Lopo * src/sndfile.c Modified validate_sfinfo() to force samplerate, channels and sections to be >= 1. In format_from_extension() replaced calls to does_extension_match() with strcmp(). * src/xi.c More work. 2003-01-06 Erik de Castro Lopo * doc/Makefile.am Added octave.html which had been left out. Found by Jan Weil. 2003-01-05 Erik de Castro Lopo * src/pvf.c src/common.h src/sndfile.c Fixed error handling for PVF files. * src/xi.c New file for handling Fasttracker 2 Extended Instrument files. Not working yet and included when configured with --enable-experimental. * src/sndfile.c src/common.h Hooked in new file xi.c. 2002-12-30 Erik de Castro Lopo * src/rx2.c Added a patch from Marek Peteraj which sheds a little more light on the slices within an RX2 file. Still need to find out data encoding. 2002-12-20 Erik de Castro Lopo * src/wav.c Started work on decoding 'acid' and 'strc' chunks. 2002-12-14 Erik de Castro Lopo * tests/peak_check_test.c Minor cleanup. 2002-12-12 Erik de Castro Lopo * tests/write_read_test.tpl Added check to make sure no error was generated when an attempt was made to read past the end of the file. 2002-12-11 Erik de Castro Lopo * doc/lists.html Added "mailto" links for all three lists. * src/pvf.c New file for Portable Voice Format files. * src/sndfile.h.in src/sndfile.c src/common.h src/command.c src/Makefile.am Added hooks for SF_FORMAT_PVF format files. * tests/write_read_test.tpl tests/std*.c Add tests for SF_FORMAT_PVF. * doc/index.html Add PVF to the compatibility matrix. * src/pcm.c src/alaw.c src/ulaw.c src/float32.c src/double64.c Previously, attempts to read beyond the end of a file would set psf->error to SFE_SHORT_ERROR. This behaviour diverged from the behaviour of the POSIX read() call but has now been fixed. Attempts to read beyond the end of the file will return a short read count but will not longer set any error. 2002-12-09 Erik de Castro Lopo * src/sndfile.c Add more sanity checking when opening a RAW file for read. When format is not RAW, zero out all members of the SF_INFO struct. * tests/raw_test.c Add bad_raw_test() to check for above problem. * tests/stdin_test.c examples/sndfile-info.c Set the format field of the SF_INFO struct to zero before calling sf_open(). * doc/api.html Add information about the need to set the format field of the SF_INFO struct to zero when opening non-RAW files for read. * configure.ac Removed use of conversion script on Solaris. Not all Solaris versions support it. * doc/lists.html New file containg details of the mailing lists. * doc/index.html Add a link to the above new file. 2002-12-04 Erik de Castro Lopo * tests/dft_cmp.c Fixed a SIGFPE on Alpha caused by a log10 (0.0). Thanks to Joshua Haberman for providing the gdb traceback. 2002-11-28 Erik de Castro Lopo * src/wav.c Added more capabilities to 'smpl' chunk parser. * src/sndfile.c Fixed some (not all) possible problems found with Flawfinder. 2002-11-24 Erik de Castro Lopo * src/sndfile.c Fixed a bug in sf_seek(). This bug could only occur when an attempt was made to read beyond the end and then sf_seek() was called with a whence parameter of SEEK_CUR. * src/file_io.c Win32's _fstati64() does not work, it returns BS. Re-implemented psf_get_filelen() in terms of psf_fseek(). * tests/write_read_test.tpl Add a test to detect above bug. * src/float_cast.h Modification to prevent compiler warnings on Mac OS X. * src/file_io.c Fixes for windows (what a f**ked OS). 2002-11-08 Erik de Castro Lopo * configure.ac Disable use of native lrint()/lrintf() on Mac OSX. These functions exist on Mac OSX 10.2 but not on 10.1. Forcing the use of the versions in src/float_cast.h means that a library compiled on 10.2 will still work on 10.1. 2002-11-06 Erik de Castro Lopo * configure.in configure.ac Renamed configure.in to configure.ac as expected by later versions of autoconf.

Thanks to Stephane Letz. * src/wav.c Changed an snprintf to LSF_SNPRINTF. * doc/Makefile.am Added version-1.html. 2002-08-14 Erik de Castro Lopo * configure.in Bumped version to 1.0.rc6. * src/*.c Modified scaling of normalised floats and doubles to integers. Until now this has been done by multiplying by 0x8000 for short output, 0x80000000 for 32 bit ints and so on. Unfortunately this can cause an overflow and wrap around in the target value. All thes values have therefore been reduced to 0x7FFF, 0x7FFFFFFF and so on. The conversion from ints to normalised floats and doubles remains unchanged. This does mean that for repeated conversions normalised float -> pcm16 -> normalised float would result in a decrease in amplitude of 0x7FFF/0x8000 on every round trip. This is undesirable but less undesireable than the wrap around I am trying to avoid. * tests/floating_point_test.c Removed file hash checking because new float scaling procedure introduced above prevented the ability to crate a has on both x86 and PowerPC systems. 2002-08-13 Erik de Castro Lopo * src/txw.c Completed reading of TXW files.

This will be a read only format. Implementation complete. * src/dwd/c Started implementation of DiamondWare Digitized files. Also read only, not complete. * src/wav.c Add parsing of 'smpl' chunk. * src/paf.c Fixed reading on un-normalized doubles and floats from 24 bit PAF files.

Implemented by Maurizio Umberto Puxeddu. * doc/command.html Docs for SFC_CALC_MAX_ALL_CHANNELS (assisted by Maurizio Umberto Puxeddu). 2002-07-18 Erik de Castro Lopo * src/sndfile.c src/gsm610.c Finalised support for GSM 6.10 AIFF files and added support for GSM 6.10 encoded RAW (header-less) files. * src/wav.c Add support for IBM_FORMAT_MULAW and IBM_FORMAT_ALAW encodings. * src/api.html Fixed more documentation bugs. 2002-07-17 Erik de Castro Lopo * src/sndfile.h src/common.h Moved some yet-to-be-implelmented values for SF_FORMAT_* from the public header file sndfile.h to the private header file common.h to avoid confusion about the actual capabilities of libsndfile. 2002-07-16 Erik de Castro Lopo * src/aiff.c src/wav.c Fixed file parsing for WAV and AIFF files containing non-audio data after the data chunk. * src/aiff.c src/sndfile.c Add support for GSM 6.10 encoded AIFF files. * tests/lossy_comp_test.c tests/Makefile.am Add tests for GSM 6.10 encoded AIFF files. * src/*.c Fix compiler warnings. 2002-07-15 Erik de Castro Lopo * tests/command_test.c For SFC_SET_NORM_* tests, change the file format from SF_FORMAT_WAV to SF_FORMAT_RAW. * src/sndfile.c Added sf_command(SFC_TEST_ADD_TRAILING_DATA) to allow testing of reading from AIFF and WAV files with non-audio data after the audio chunk. * src/common.h Add test commands SFC_TEST_WAV_ADD_INFO_CHUNK and SFC_TEST_AIFF_ADD_INST_CHUNK. When these commands are working, they will be moved to src/sndfile.h * src/aiff.c src/wav.c Begin implementation of XXXX_command() hook for sf_command(). * tests/write_read_test.tpl Added sf_command (SFC_TEST_ADD_TRAILING_DATA) to ensure above new code was working. 2002-07-13 Erik de Castro Lopo * tests/update_header_test.c Allow read sample count == write sample count - 1 to fix problems with VOC files. * tests/write_read_test.tpl tests/pcm_test.tpl Fixed some problems in the test suite discovered by using Valgrind. 2002-07-12 Erik de Castro Lopo * tests/utils.[ch] tests/*.c Renamed check_log_buffer() to check_log_buffer_or_die(). * src/sndfile.c SFC_UPDATE_HEADER_NOW and SFC_SETUPDATE_HEADER_AUTO almost finished. Works for all file formats other than VOC. 2002-07-11 Erik de Castro Lopo * src/sndfile.[ch] src/common.h Started adding functionality to allow the file header to be updated before the file is closed on files open for SFM_WRITE. This was requested by Maurizio Umberto Puxeddu who is using libsndfile for file I/O in iCSound. * tests/update_header_test.c New test program to test that the above functionality is working correctly. * tests/peak_chunk_test.c tests/floating_point_test.c Cleanups. 2002-07-10 Erik de Castro Lopo * src/sfendian.[ch] Changed length count parameters for all endswap_XXX() functions from sf_count_t (which can be 64 bit even on 32 bit architectures) to int. These functions are only called frin inside the library, are always called with integer parameters and doing the actual calculation on 64 bit values is slow in comparision to doing it on ints. * examples/sndfile-play.c More playback hacking for Win32. 2002-07-09 Erik de Castro Lopo * src/common.c In psf_log_printf(), changed %D format conversion specifier to %M (marker) and added %D specifier for printing the sf_count_t type. * src/*.c Changed all usage of psf_log_printf() with %D format conversion specifiers to use %M conversion instead. * tests/pcm_test.tpl tests/pcm_test.def New files to autogen pcm_test.c. * src/pcm.c Fixed bug in scaling floats and doubles to 24 bit PCM and vice versa. 2002-07-08 Erik de Castro Lopo * configure.in Fix setup of $ac_cv_sys_largefile_CFLAGS so that sndfile.pc gets valid values for CFLAGS. * examples/sndfile-play.c Start adding playback support for Win32. 2002-07-07 Erik de Castro Lopo * src/*.c Worked to removed compiler warnings. Extensive refactoring. * src/common.[ch] Added function psf_memset() which works like the standard C function memset but takes and sf_count_t as the length parameter. * src/sndfile.c Replaced calls to memset(0 with calls to psf_memset() as required. 2002-07-06 Erik de Castro Lopo * src/sndfile.c Added "libsndfile : " to the start of all error messages. This was suggested by Conrad Parker author of Sweep ( http://sweep.sourceforge.net/ ). * src/sfendian.[ch] Added endswap_XXXX_copy() functions. * src/pcm.c src/float32.c src/double64.c Use endswap_XXXX_copy() functions and removed dead code. Cleanups and optimisations. 2002-07-05 Erik de Castro Lopo * src/sndfile.c src/sndfile.h Gave values to all the SFC_* enum values to allow better control of the interface as commands are added and removed. Added new command SFC_SET_ADD_PEAK_CHUNK. * src/wav.c src/aiff.c Modified wav_write_header and aiff_write_header to make addition of a PEAK chunk optional, even on floating point files. * tests/benchmark.tpl Added call to sf_command(SFC_SET_ADD_PEAK_CHUNK) to turn off addition of a PEAK chunk for the benchmark where we are trying to miximize speed. * src.pcm.c Changed tribyte typedef to something more sensible. Further conversion speed ups. 2002-07-03 Erik de Castro Lopo * src/command.c In major_formats rename "Sphere NIST" to "NIST Sphere". * src/common.c src/sfendian.c Moved all endswap_XXX_array() functions to sfendian.c. These functions will be tweaked to provide maximum performance. Since maximum performance on one platform does not guarantee maximum performance on another, a small set of functions will be written and the optimal one chosen at compile time. * src/common.h src/sfendian.h Declarations of all endswap_XXX_array() functions moved to sfendian.h. * src/Makefile.am Add sfendian.c to build targets. 2002-07-01 Erik de Castro Lopo * src/pcm.c src/sfendian.h Re-coded PCM encoders and decoders to match or better the speed of libsndfile version 0.0.28. 2002-06-30 Erik de Castro Lopo * src/wav.c Add checking for WAVPACK data in standard PCM WAV file. Return error if found. This WAVPACK is *WAY* broken. It uses the same PCM WAV file header and then stores non-PCM data. * tests/benchmark.tpl Added more tests. 2002-06-29 Erik de Castro Lopo * tests/benchmark.tpl Added conditional definition of M_PI. For Win32, set WRITE_PERMS to 0777. * Win32/Makefile.msvc Added target to make generate program on Win32. * src/samplitude.c Removed handler for Samplitude RAP file format. This file type seems rarer than hens teeth and is completely undocumented. * src/common.h src/sndfile.c src/Makefile.am Win32/Makefile.msvc Removed references to sampltiude RAP format. * tests/benchmark.tpl Benchmark program now prints the libsndfile version number when run. This program was also backported to version 0 to compare results. Version 1.0.0rc2 is faster than version 0.0.28 on most conversions but slower on some. The slow ones need to be fixed before final release. 2002-06-28 Erik de Castro Lopo * tests/benchmark.def tests/benchmark.tpl New files which generate tests/benchmark.c using Autogen. Added int -> SF_FORMAT_PCM_24 test. * tests/benchmark.c Now and Autogen output file. * tests/Makefile.am Updated for above changes. 2002-06-27 Erik de Castro Lopo * tests/benchmark.c Basic benchmark program complete. Need to convert it to Autogen. * Win32/Makefile.msvc Added benchmark.exe target. 2002-06-26 Erik de Castro Lopo * examples/generate.c New program to generate a number of different output file formats from a single input file. This allows testing of the created files. * tests/benchmark.c New test program to benchmark libsndfile. Nowhere near complete yet. * examples/Makefile.am tests/Makefile.am New make rules for the two new programs. 2002-06-25 Erik de Castro Lopo * Win32/libsndfile.def Removed definition for sf_signal_max(). * src/sndfile.c Removed cruft. * doc/index.html A number of documentation bugs were fixed. Thanks to Anand Kumria. * doc/version-1.html Minor doc updates. * configure.in Bumped version to 1.0.0rc2. * src/sf_command.h src/Makefile.am Removed the header file as it was no longer being used. Thanks to Anand Kunria for spotting this. * doc/index.html A number of documentation bugs were fixed. Thanks to Anand Kumria. 2002-06-24 Erik de Castro Lopo * src/common.h Test for Win32 before testing SIZEOF_OFF_T so that it works correctly on Win32.. * src/file_io.c Win32 fixes to ensure O_BINARY is used for file open. * doc/win32.html New file documenting the building libsndfile on Win32. * doc/*.html Updating of documentation. 2002-06-23 Erik de Castro Lopo * tests/pcm_test.c Minor changes to allow easier determination of test file name. * src/sndfile.[ch] Removed function sf_signal_max(). * examples/sndfile-play.c Changed call to sf_signal_max() to a call to sf_command(). 2002-06-22 Erik de Castro Lopo * src/format.c src/command.c Renamed format.c to command.c which will now include code for sf_command() calls to perform operations other than format commands. * src/sndfile.c src/sndfile.h Removed function sf_get_signal_max() which is replaced by commands passed to sf_command(). * src/command.c Implement commands SFC_CALC_SIGNAL_MAX. * doc/command.html Documented SFC_CALC_SIGNAL_MAX. 2002-06-21 Erik de Castro Lopo * examples/sndfile-play.c Mods to make sndfile-play work on Solaris. The program sndfile-play now runs on Linux, MaxOSX and Solaris. Win32 to come. * src/format.c Added SF_FORMAT_DWVW_* to subtype_formats array. * src/nist.c Added support for 8 bit NIST Sphere files. Example file supplied by Anand Kumria. 2002-06-20 Erik de Castro Lopo * examples/sndfile-info.c Tidy up of output format. * examnples/sndfile-play.c Mods to make sndfile-play work on MacOSX using Apple's CoreAudio API. * configure.in Add new variables OS_SPECIFIC_INCLUDES and OS_SPECIFIC_LINKS which were required to supply extra include paths and link parameters to get sndfile-play working on MacOSX. * examples/Makefile.am Use OS_SPOECIFIC_INCLUDES and OS_SPECIFIC_LINKS to build commands for sndfile-play. 2002-06-19 Erik de Castro Lopo * src/nist.c Added ability to read/write new NIST Sphere file types (A-law, u-law). Header parser was re-written from scratch. Example files supplied by Anand Kumria. * src/sndfile.c Support for A-law and u-law NIST files. * tests/Makefile.am tests/lossy_comp_test.c Tests for A-law and u-law NIST files. 2002-06-18 Erik de Castro Lopo * tests/utils.c Fixed an error in error string. 2002-06-17 Erik de Castro Lopo * acinclude.m4 Removed exit command to allow cross-compiling. * Win32/unistd.h src/file_io.c Moved contents of first file into the second file (enclosed in #ifdef). Win32/unistd.h is now an empty file but still must be there for libsndfile to compile on Win32. * src/sd2.c, src/sndfile.c: Fixes for Sound Designer II files on big endian systems. 2002-06-16 Erik de Castro Lopo * configure.in Modified to work around problems with crappy MacOSX version of sed. Added sanity check for proper values for CFLAGS. 2002-06-14 Erik de Castro Lopo * src/sndfile.c Code clean up in sf_open (). * Win32/Makefile.msvc Michael Fink's contributed MSVC++ makefile was hacked to bits and put back together in a new improved form. * src/file_io.c Fixes for Win32; _lseeki64() returns an invalid argument for calls like _lseeki64(fd, 0, SEEK_CUR) so need to use _telli64 (fd) instead. * src/common.h src/sndfile.c src/wav.c src/aiff.c Added SFE_LOG_OVERRUN error. Added termination for potential infinite loop when parsing file headers. * src/wav.c src/w64.c Fixed bug casuing incorrect header generation when opening file read/write. 2002-06-12 Erik de Castro Lopo * doc/api.html Improved the documentation to make it clearer that the file read method and the underlying file format are completely disconnected. Suggested by Josh Green. * doc/command.html Started correcting docs to take into account changes made to the operations of the sf_command () function. Not complete yet. * src/sndfile.c Reverted some changes which had broken the partially working SDII header parsing. Now have access to an iBook with OS X so reading and writing SDII files on all platforms should be a reality in the near future. On Mac this will involve reading the resource fork via the standard MacOS API. To move a file from Mac to another OS, the resource and data forks will need to be combined before transfer. The combined file will be read on both Mac and other OSes like any other file. 2002-06-08 Erik de Castro Lopo * ltmain.sh Applied a patch from http://fink.sourceforge.net/doc/porting/libtool.php which allows libsndfile to compile on MacOSX 10.1. This patch should not interfere with compiling on other OSes. * src/GSM610/private.h Changes to fix compile problems on MacOSX (see src/GSM610/ChangeLog). * src/float_cast.h Added MacOSX replacements for lrint() and lrintf(). 2002-06-05 Erik de Castro Lopo * src/sndfile.c Replaced the code to print the filename to the log buffer when a file is opened. This code seems to have been left out during the merge of sf_open_read() and sf_open_write() to make a single functions sf_open(). 2002-06-01 Erik de Castro Lopo * src/wav.c Fixed a bug where the WAV header parser was going into an infinite loop on a badly formed LIST chunk. File supplied by David Viens. 2002-05-25 Erik de Castro Lopo * configure.in Added a message at the end of the configuration process to warn about the need for the use of pkg-config when linking programs against version 1 of libsndfile. * doc/pkg-config.html New documentation file containing details of how to use pkg-config to retrieve settings for CFLAGS and library locations for linking files against version 1 of libsndfile. 2002-05-17 Erik de Castro Lopo * src/wav.c Fixed minor bug in handling of so-called ACIDized WAV files. 2002-05-16 Erik de Castro Lopo * Win32/libsndfile.def Win32/Makefile.msvc Two new files contributed by Michael Fink (from the winLAME project) which allows libsndfile to be built on windows in a MSDOS box by doing "nmake -f Makefile.msvc". Way cool! 2002-05-15 Erik de Castro Lopo * configure.in MacOSX is SSSOOOOOOO screwed up!!! I can't believe how hard it is to generate a tarball which will configure and compile on that platform. Joined the libtool mailing list to try and get some answers. 2002-05-13 Erik de Castro Lopo * configure.in Changed to autoconf version 2.50. MacOSX uses autoconf version 2.53 which is incompatible with with version 2.13 which had been using until now. The AC_SYS_LARGE_FILE macro distributed withe autoconf 2.50 is missing a few features so AC_SYS_EXTRA_LARGE file was defined to replace it. * configure.in Changed to automake version 1.5 to try and make a tarball which will work on MacOSX. 2002-05-12 Erik de Castro Lopo * src/wav_gsm610.c Changed name to gsm610.c. Added reading/writing of headerless files. * src/sndfile.c src/raw.c Added ability to read/write headerless (SF_FORMAT_RAW) GSM 6.10 files. 2002-05-11 Erik de Castro Lopo * tests/lossy_comp_test.c Clean up in preparation for Autogen-ing this file. * src/GSM610/*.[ch] Code cleanup and prepartion forgetting file seek working. Details in src/GSM610/ChangeLog. * sndfile.pc.in Testing complete. Is sndfile.m4 still needed? 2002-05-09 Erik de Castro Lopo * tests/write_read_test.tpl tests/rdwr_test.tpl Merged tests from these two programs into write_read_test.tpl and deleted rdwr_test.tpl. 2002-05-08 Erik de Castro Lopo * src/w64.c src/svx.c src/paf.c Fixed bugs in read/write mode. 2002-05-07 Erik de Castro Lopo * examples/Makefile.am Renamed sfplay.c to sndfile-play.c and sndfile_info.c to sndfile-info.c for consistency when these programs become part of the Debian package sndfile-programs. * sndfile.pc.in New file to replace sndfile-config.in. Libsndfile now uses the pkg-config model for providing installation parameters to dependant programs. * src/sndfile.c Cleanup of code in sf_open(). 2002-05-06 Erik de Castro Lopo * tests/utils.tpl tests/write_read_test.tpl More conversion to Autogen fixes and enchancements. * src/*.c Read/write mode is now working for 16, 24 and 32 bit PCM as well as 32 bit float and 64 bit double data. More tests still required. * src/Makefile.am Added DISTCLEANFILES target to remove config.status and config.last. * Win32/Makefile.am MacOS/Makefile.am Added DISTCLEANFILES target to remove Makefile. 2002-05-05 Erik de Castro Lopo * src/*.[ch] tests/rdwr_test.c More verifying workings of read/write mode. Fixing bugs found. * tests/utils.[ch] Made these files Autogen generated files. * tests/util.tpl tests/util.def New Autogen files to generate utils.[ch]. Moved some generic test functions into this file. Autogen is such a great tool! 2002-05-03 Erik de Castro Lopo * src/pcm.c src/float_cast.h Win32/config.h Fixed a couple of Win32 specific bugs pointed out by Michael Fink (maintainer of WinLAME) and David Viens. * tests/check_log_buffer.[ch] tests/utils.[ch] Moved check_log_buffer() to utils.[ch] and deleted old file. 2002-05-02 Erik de Castro Lopo * src/common.[ch] src/sndfile.c New function psf_default_seek() which will be the default seek function for things like PCM and floating point data. This default is set for both read and write in sf_open() but can be over-ridden by any codec during it's initialisation. 2002-05-01 Erik de Castro Lopo * src/au.c AU files use a data size value of -1 to mean unknown. Fixed au_open_read() to allow opening files like this. * tests/rdwr_test .c Added more tests. * src/sndfile.c Fixed bugs in read/write mode found due to improvements in the test program. 2002-04-30 Erik de Castro Lopo * tests/rdwr_test .c New file for testing read/write mode. 2002-04-29 Erik de Castro Lopo * m4/* Removed all m4 macros from this directory as they get concatenated to form the file aclocal.m4 anyway. * sndfile.m4 Moved this from the m4 directory to the root directory asn this is part of the distribution and is installed during "make install". 2002-04-29 Erik de Castro Lopo * src/float32.c Removed logging of peaks for all file formats other than AIFF and WAV. * tests/write_read_test.tpl tests/write_read_test.def New files which autogen uses to generate write_read_test.c. Doing it this way makes write_read_test.c far easier to maintain. Other test programs will be converted to autogen in the near future. * src/*.c Fixed a few bugs found when testing on Sparc (bug endian) Solaris. 2002-04-28 Erik de Castro Lopo * doc/*.html Fixed documention versioning. * configure.in Fixed a bug in the routines which search for Large File Support on systems which have large file support by defualt. 2002-04-27 Erik de Castro Lopo * src/*.[ch] Found and fixed an issue which can cause a bug in other software (I was porting Conrad Parker's Sweep program from version 0 of the library to version 1). When opening a file for write, the libsndfile code would set the sfinfo.samples field to a maximum value. * tests/write_read_test.c Added tests to detect the above problem. 2002-04-25 Erik de Castro Lopo * src/*.[ch] Finished base implementation of read/write mode. Much more testing still needed. * m4/largefile.m4 Macro for detecting Large File Standard capabilities. This macro was ripped out of the aclocal.m4 file of GNU tar-1.13. * configure.in Added detection of large file support. Files larger than 2 Gigabytes should now be supported on 64 bit platforms and many 32 bit platforms including Linux (2.4 kernel, glibc-2.2), *BSD, MacOS, Win32. * libsndfile_convert_version.py A Python script which attempts to autoconvert code written to use version 0 to version 1. 2002-04-24 Erik de Castro Lopo * src/*.[ch] Finished base implementation of read/write mode. Much more testing still needed. * tests/write_read_test.c Preliminary tests for read/write mode added. More needed. 2002-04-20 Erik de Castro Lopo * src/sndfile.[ch] Removed sf_open_read() and sf_open_write() functions,replacting them with sf_open() which takes an extra mode parameter (SF_OPEN_READ, SF_OPEN_WRITE, or SF_OPEN_RDWR). This new function sf_open can now be modified to allow opening a file formodification (RDWR). 2002-04-19 Erik de Castro Lopo * src/*.c Completed merging of separate xxx_open_read() and xxx_open_write() functions. All tests pass. 2002-04-18 Erik de Castro Lopo * src/au.c Massive refactoring required to merge au_open_read() with au_open_write() to create au_open(). 2002-04-17 Erik de Castro Lopo * src/*.c Started changes required to allow a sound file to be opened in read/write mode, with separate file pointers for read and write. This involves merging of encoder/decoder functions like pcm_read_init() and pcm_write_init() int a new function pcm_init() as well as doing something similar for all the file type specific functions ie aiff_open_read() and aiff_open_write() were merged to make the function aiff_open(). 2002-04-15 Erik de Castro Lopo * src/file_io.c New file containing psf_fopen(), psf_fread(), psf_fwrite(), psf_fseek() and psf_ftell() functions. These function will replace use of fopen/fread/fwrite etc and allow access to files larger than 2 gigabytes on a number of 32 bit OSes (Linux on x86, 32 bit Solaris user space apps, Win32 and MacOS). * src/*.c Replaced all instances of fopen with psf_open, fread with psd_read, fwrite with psf_write and so on. 2002-03-11 Erik de Castro Lopo * src/dwvw.c Finally fixed all known problems with 12, 16 and 24 bit DWVW encoding. * tests/floating_point_test.c Added tests for 12, 16 and 24 bit DWVW encoding. 2002-03-03 Erik de Castro Lopo * m4/endian.m4 Defines a new m4 macro AC_C_FIND_ENDIAN, for determining the endian-ness of the target CPU. It first checks for the definition of BYTE_ORDER in , then in and . If none of these work and the C compiler is not a cross compiler it compiles and runs a program to test for endian-ness. If the compiler is a cross compiler it makes a guess based on $target_cpu. * configure.in Modified to use AC_C_FIND_ENDIAN. * src/sfendian.h Simplified. 2002-02-23 Erik de Castro Lopo * tests/floating_point_test.c Tests completely rewritten using the dft_cmp function. Now able to calculate a quick guesstimate of the Signal to Noise Ratio of the encoder. 2002-02-15 Erik de Castro Lopo * tests/dft_cmp.[ch] New files containing functions for comparing pre and post lossily compressed data using a quickly hacked DFT. * tests/utils.[ch] New files containing functions for saving pre and post encoded data in a file readable by the GNU Octave package. 2002-02-13 Erik de Castro Lopo * m4/lrint.m4 m4/lrintf.m4 Fixed m4 macros to define HAVE_LRINT and HAVE_LRINTF even when the test is cached. 2002-02-12 Erik de Castro Lopo * tests/floating_point_test.c Fixed improper use of strncat (). 2002-02-11 Erik de Castro Lopo * tests/headerless_test.c New test program to test the ability to open and read a known file type as a RAW header-less file. 2002-02-07 Erik de Castro Lopo * tests/losy_comp_test.c Added a test to ensure that the data read from a file is not all zeros. * examples/sfconvert.c Added "-gsm610" encoding types. 2002-01-29 Erik de Castro Lopo * examples/sfconvert.c Added "-dwvw12", "-dwvw16" and "-dwvw24" encoding types. * tests/dwvw_test.c New file for testing DWVW encoder/decoder. 2002-01-28 Erik de Castro Lopo * src/dwvw.c Implemented writing of DWVW. 12 bit seems to work, 16 and 24 bit still broken. * src/aiff.c Improved reporting of encoding types. * src/voc.c Clean up. 2002-01-27 Erik de Castro Lopo * src/dwvw.c New file implementing lossless Delta Word Variable Width (DWVW) encoding. Reading 12 bit DWVW is now working. * src/aiff.c common.h sndfile.c Added hooks for DWVW encoded AIFF and RAW files. 2002-01-15 Erik de Castro Lopo * src/w64.c Robustify header parsing. * src/wav_w64.h Header file wav.h was renamed to wav_w64.h to signify sharing of definitions across the two file types. * src/wav.c src/w64.c src/wav_w64.c Refactoring. Modified and moved functions with a high degree of similarity between wav.c and w64.c to wav_w64.c. 2002-01-14 Erik de Castro Lopo * src/w64.c Completed work on getting read and write working. * examples/sfplay.c Added code to scale floating point data so it plays at a reasonable volume. * tests/Makefile.am tests/write_read_test.c Added tests for W64 files. 2002-01-13 Erik de Castro Lopo * src/*.c Modded all code in file header writing routines to use psf_new_binheader_writef(). Removed psf_binheader_writef() from src/common.c. Globally replaced psf_new_binheader_writef with psf_binheader_writef. 2002-01-12 Erik de Castro Lopo * src/*.c Modded all code in file parsing routines to use psf_new_binheader_readf(). Removed psf_binheader_readf() from src/common.c. Globally replaced psf_new_binheader_readf with psf_binheader_readf. * src/common.[ch] Added new function psf_new_binheader_writef () which will soon replace psf_binheader_writef (). The new function has basically the same function as the original but has a more flexible and capable interface. It also allows the writing of 64 bit integer values for files contains 64 bit file offsets. 2002-01-11 Erik de Castro Lopo * src/formats.c src/sndfile.c src/sndfile.h Added code allowing full enumeration of supported file formats via the sf_command () interface. This feature will allow applications to avoid needing recompilation when support for new file formats are added to libsndfile. * tests/command_test.c Added test code for the above feature. * examples/list_formats.c New file. An example of the use of the supported file enumeration interface. This program lists all the major formats and for each major format the supported subformats. 2002-01-10 Erik de Castro Lopo * src/*.[ch] tests/*.c Changed command parameter of sf_command () function from a test string to an int. The valid values for the command parameter begin with SFC_ and are listed in src/sndfile.h. 2001-12-20 Erik de Castro Lopo * src/formats.c src/sndfile.c Added an way of enumerating a set of common file formats using the sf_command () interface. This interface was suggested by Dominic Mazzoni, one of the main authors of Audacity (http://audacity.sourceforge.net/). 2001-12-26 Erik de Castro Lopo * src/sndfile.c Added checking of filename parameter in sf_open_read (). Previousy, if a NULL pointer was passed the library would segfault. 2001-12-18 Erik de Castro Lopo * src/common.c src/common.h Changed the len parameter of the endswap_*_array () functions from type int to type long. * src/pcm.c Fixed a problem which 2001-12-15 Erik de Castro Lopo * src/sndfile.c Added conditional #include for EMX/gcc on OS/2. Thanks to Paul Hartman for pointing this out. * tests/lossy_comp_test.c tests/floating_point_test.c Added definitions for M_PI for when it isn't defined in . 2001-11-30 Erik de Castro Lopo * src/ircam.c Re-implemented the header reader. Old version was making incorrect assumptions about the endian-ness of the file from the magic number at the start of the file. The new code looks at the integer which holds the number of channels and determines the endian-ness from that. 2001-11-30 Erik de Castro Lopo * src/aiff.c Added support for other AIFC types ('raw ', 'in32', '23ni'). Further work on IMA ADPCM encoding. 2001-11-29 Erik de Castro Lopo * src/ima_adpcm.c Renamed from wav_ima_adpcm.c. This file will soon handle IMA ADPCM encodings for both WAV and AIFF files. * src/aiff.c Started adding IMA ADPCM support. 2001-11-28 Erik de Castro Lopo * src/double.c New file for handling double precision floating point (SF_FORMAT_DOUBLE) data. * src/wav.c src/aiff.c src/au.c src/raw.c Added support for SF_FORMAT_DOUBLE data. * src/common.[ch] Addition of endswap_long_array () for endian swapping 64 bit integers. This function will work correctly on processors with 32 bit and 64 bit longs. Optimised endswap_short_array () and endswap_int_array (). * tests/pcm_test.c Added and extra check. After the first file of each type is written to disk a checksum is performed of the first 64 bytes and checked against a pre- calculated value. This will work whatever the endian-ness of the host machine. 2001-11-27 Erik de Castro Lopo * src/aiff.c Added handling of u-law, A-law encoded AIFF files. Thanks to Tom Erbe for supplying example files. * tests/lossy_comp_test.c Added tests for above. * src/common.h src/*.c Removed function typedefs from common.h and function pointer casting in all the other files. This allows the compiler to perform proper type checking. Hopefully this will prevernt problems like the sf_seek bug for OpenBSD, BeOS etc. * src/common.[ch] Added new function psf_new_binheader_readf () which will eventually replace psf_binheader_readf (). The new function has basically the same function as the original but has a more flexible and capable interface. It also allows the reading of 64 bit integer values for files contains 64 bit file offsets. 2001-11-26 Erik de Castro Lopo * src/voc.c Completed implementation of VOC file handling. Can now handle 8 and 16 bit PCM, u-law and A-law files with one or two channels. * src/write_read_test.c tests/lossy_comp_test.c Added tests for VOC files. 2001-11-22 Erik de Castro Lopo * src/float_cast.h Added inline asm version of lrint/lrintf for MacOS. Solution provided by Stephane Letz. * src/voc.c More work on this braindamaged format. The VOC files produced by SoX also have a number of inconsistencies. 2001-11-19 Erik de Castro Lopo * src/paf.c Added support for 8 bit PCM PAF files. * tests/write_read_test.c Added tests for 8 bit PAF files. 2001-11-18 Erik de Castro Lopo * tests/pcm_test.c New test program to test for correct scaling of integer values between different sized integer containers (ie short -> int). The new specs for libsndfile state that when the source and destination containers are of a different size, the most significant bit of the source value becomes the most significant bit of the destination container. * src/pcm.c src/paf.c Modified to pass the above test program. * tests/write_read_test.c tests/lossy_comp_test.c Modified to work with the new scaling rules. 2001-11-17 Erik de Castro Lopo * src/raw.c tests/write_read_test.c tests/write_read_test.c Added ability to do raw reads/writes of float, u-law and A-law files. * src/*.[ch] examples/*.[ch] tests/*.[ch] Removed dependance on pcmbitwidth field of SF_INFO struct and moved to new SF_FORMAT_* types and use of SF_ENDIAN_BIG/LITTLE/CPU. 2001-11-12 Erik de Castro Lopo * src/*.[ch] Started implmentation of major changes documented in doc/version1.html. Removed all usage of off_t which is not part of the ISO C standard. All places which were using it are now using type long which is the type of the offset parameter for the fseek function. This should fix problems on BeOS, MacOS and *BSD like systems which were failing "make check" because sizeof (long) != sizeof (off_t). -------------------------------------------------------------------------------- This is the boundary between version 1 of the library above and version 0 below. -------------------------------------------------------------------------------- 2001-11-11 Erik de Castro Lopo * examples/sfplay_beos.cpp Added BeOS version of sfplay.c. This needs to be compiled using a C++ compiler so is therefore not built by default. Thanks to Marcus Overhagen for providing this. 2001-11-10 Erik de Castro Lopo * examples/sfplay.c New example file showing how libsndfile can be used to read and play a sound file. At the moment on Linux is supported. Others will follow in the near future. 2001-11-09 Erik de Castro Lopo * src/pcm.c Fixed problem with normalisation code where a value of 1.0 could map to a value greater than MAX_SHORT or MAX_INT. Thanks to Roger Dannenberg for pointing this out. 2001-11-08 Erik de Castro Lopo * src/pcm.c Fixed scaling issue when reading/writing 8 bit files using sf_read/sf_write_short (). On read, values are scaled so that the most significant bit in the char ends up in the most significant bit of the short. On write, values are scaled so that most significant bit in the short ends up as the most significant bit in the char. 2001-11-07 Erik de Castro Lopo * src/au.c src/sndfile.c Added support for 32 bit float data in big and little endian AU files. * tests/write_read_test.c Added tests for 32 bit float data in AU files. 2001-11-06 Erik de Castro Lopo * tests/lossy_comp_test.c Finalised testing of stereo files where possible. 2001-11-05 Erik de Castro Lopo * src/wav_ms_adpcm.c Fixed bug in writing stereo MS ADPCM WAV files. Thanks to Xu Xin for pointing out this problem. 2001-10-24 Erik de Castro Lopo * src/wav_ms_adpcm.c Modified function srate2blocksize () to handle 44k1Hz stereo files. 2001-10-21 Erik de Castro Lopo * src/w64.c Added support for Sonic Foundry 64 bit WAV format. As Linux (my main development platform) does not yet support 64 bit file offsets by default, current handling of this file format treats everything as 32 bit and fails openning the file, if it finds anything that goes beyond 32 bit values. * src/sndfile.[hc] src/common.h src/Makefile.am Added hooks for W64 support. 2001-10-21 Erik de Castro Lopo * configure.in Added more warnings options to CFLAGS when the gcc compiler is detected. * src/*.[ch] tests/*.c examples/*.c Started fixing the warning messages due to the new CFLASG. * src/voc.c More work on VOC file read/writing. * src/paf.c Found that PAF files were not checking the normalisation flag when reading or writing floats and doubles. Fixed it. * tests/floating_point_test.c Added specific test for the above problem. * src/float_cast.h src/pcm.c Added a section for Win32 to define lrint () and lrintf () in the header and implement it in the pcm.c 2001-10-20 Erik de Castro Lopo * sndfile-config.in m4/sndfile.m4 These files were donated by Conrad Parker who also provided instructions on how to install them using autoconf/automake. * src/float_cast.h Fiddled around with this file some more. On Linux and other gcc supported OSes use the C99 functions lrintf() and lrint() for casting from floating point to int without incurring the huge perfromance penalty (particularly on the i386 family) caused by the regular C cast from float to int. These new C99 functions replace the FLOAT_TO_* and DOUBLE_TO_* macros which I had been playing with. * configure.in m4/lrint.m4 m4/lrintf.m4 Add detection of these functions. 2001-10-17 Erik de Castro Lopo * src/voc.c Completed code for reading VOC files containing a single audio data segment. Started implementing code to handle files with multiple VOC_SOUND_DATA segments but couldn't be bothered finishing it. Multiple segment files can have different sample rates for different sections and other nasties like silence and repeat segments. 2001-10-16 Erik de Castro Lopo * src/common.h src/*.c Removed SF_PRIVATE struct field fdata and replaced it with extra_data. * src/voc.c Further development of the read part of this woefult file format. 2001-10-04 Erik de Castro Lopo * src/float_cast.h Implemented gcc and i386 floating point to int cast macros. Standard cast will be used when not on gcc for i385. * src/pcm.c Modified all uses of FLOAT/DOUBLE_TO_INT and FLOAT/DOUBLE_TO_SHORT casts to comply with macros in float_cast.h. 2001-10-04 Erik de Castro Lopo * src/voc.c Changed the TYPE_xxx enum names to VOC_TYPE_xxx to prevent name clashes on MacOS with CodeWarrior 6.0. * MacOS/MacOS-readme.txt Updated the compile instructions. Probably still need work as I don't have access to a Mac. 2001-10-01 Erik de Castro Lopo * src/wav.c src/aiff.c common.c Changed all references to snprintf to LSF_SNPRINTF and all vsnprintf to LSF_VSNPRINTF. LSF_VSNPRINTF and LSF_VSNPRINTF are defined in common.h. * src/common.h Added checking of HAVE_SNPRINTF and HAVE_VSNPRINTF and defining LSF_VSNPRINTF and LSF_VSNPRINTF to appropriate values. * src/missing.c New file containing a minimal implementation of snprintf and vsnprintf functions named missing_snprintf and missing_vsnprintf respectively. These are only compliled into the binary if snprintf and/or vsnprintf are not available. 2001-09-29 Erik de Castro Lopo * src/ircam.c New file to handle Berkeley/IRCAM/CARL files. * src/sndfile.c src/common.h Modified for IRCAM handling. * tests/*.c Added tests for IRCAM files. 2001-09-27 Erik de Castro Lopo * src/wav.c Apparently microsoft windows (tm) doesn't like ulaw and Alaw WAV files with 20 byte format chunks (contrary to ms's own documentation). Fixed the WAV header writing code to generate smaller ms compliant ulaw and Alaw WAV files. 2001-09-17 Erik de Castro Lopo * tests/stdio_test.sh tests/stdio_test.c Shell script was rewritten as a C program due to incompatibilities of the sh shell on Linux and Solaris. 2001-09-16 Erik de Castro Lopo * tests/stdio_test.sh tests/stdout_test.c tests/stdin_test.c New test programs to verify the correct operation of reading from stdin and writing to stdout. * src/sndfile.c wav.c au.c nist.c paf.c Fixed a bugs uncovered by the new test programs above. 2001-09-15 Erik de Castro Lopo * src/sndfile.c wav.c Fixed a bug preventing reading a file from stdin. Found by T. Narita. 2001-09-12 Erik de Castro Lopo * src/common.h Fixed a problem on OpenBSD 2.9 which was causing sf_seek() to fail on IMA WAV files. Root cause was the declaration of the func_seek typedef not matching the functions it was actually being used to point to. In OpenBSD sizeof (off_t) != sizeof (int). Thanks to Heikki Korpela for allowing me to log into his OpenBSD machine to debug this problem. 2001-09-03 Erik de Castro Lopo * src/sndfile.c Implemented sf_command ("norm float"). * src/*.c Implemented handling of sf_command ("set-norm-float"). Float normalization can now be turned on and off. * tests/double_test.c Renamed to floating_point_test.c. Modified to include tests for all scaled reads and writes of floats and doubles. * src/au_g72x.c Fixed bug in normalization code found with improved floating_point_test program. * src/wav.c Added code for parsing 'INFO' and 'LIST' chunks. Will be used for extract text annotations from WAV files. * src/aiff.c Added code for parsing '(c) ' and 'ANNO' chunks. Will be used for extract text annotations from WAV files. 2001-09-02 Erik de Castro Lopo * examples/sf_info.c example/Makefile.am Renamed to sndfile_info.c. The program sndfile_info will now be installed when the library is installed. * src/float_cast.h New file defining floating point to short and int casts. These casts will eventually replace all flot and double casts to short and int. See comments at the top of the file for the reasoning. * src/*.c Changed all default float and double casts to short or int with macros defined in floatcast.h. At the moment these casts do nothing. They will be replaced with faster float to int cast operations in the near future. 2001-08-31 Erik de Castro Lopo * tests/command_test.c New file for testing sf_command () functionality. * src/sndfile.c Revisiting of error return values of some functions. Started implementing sf_command () a new function will allow on-the-fly modification of library behaviour, or instance, sample value scaling. * src/common.h Added hook for format specific sf_command () calls to SNDFILE struct. * doc/api.html Updated and errors corrected. * doc/command.html New documentation file explaining new sf_command () function. 2001-08-11 Erik de Castro Lopo * src/sndfile.c Fixed error return values from sf_read*() and sf_write*(). There were numerous instances of -1 being returned through size_t. These now all set error int the SF_PRIVATE struct and return 0. Thanks to David Viens for spotting this. 2001-08-01 Erik de Castro Lopo * src/common.c Fixed use of va_arg() calls that were causing warning messages with the latest version of gcc (thanks Maurizio Umberto Puxeddu). 2001-07-25 Erik de Castro Lopo * src/*.c src/sfendian.h Moved definition of MAKE_MARKER macro to sfendian.h 2001-07-23 Erik de Castro Lopo * src/sndfile.c Modified sf_get_lib_version () so that version string will be visible using the Unix strings command. * examples/Makefile.am examples/sfinfo.c Renamed sfinfo program and source code to sf_info. This prevents a name clash with the program included with libaudiofile. 2001-07-22 Erik de Castro Lopo * tests/read_seek_test.c tests/lossy_comp_test.c Added tests for sf_read_float () and sf_readf_float (). * src/voc.c New files for handling Creative Voice files (not complete). * src/samplitude.c New files for handling Samplitude files (not complete). 2001-07-21 Erik de Castro Lopo * src/aiff.c src/au.c src/paf.c src/svx.c src/wav.c Converted these files to using psf_binheader_readf() function. Will soon be ready to attempt to make reading writing from pipes work reliably. * src/*.[ch] Added code for sf_read_float () and sf_readf_float () methods of accessing file data. 2001-07-20 Erik de Castro Lopo * src/paf.c src/wav_gsm610.c Removed two printf()s which had escaped notice for some time (thanks Sigbjørn Skjæret). 2001-07-19 Erik de Castro Lopo * src/wav_gsm610.c Fixed a bug which prevented GSM 6.10 encoded WAV files generated by libsndfile from being played in Windoze (thanks klay). 2001-07-18 Erik de Castro Lopo * src/common.[ch] Implemented psf_binheader_readf() which will do for file header reading what psf_binheader_writef() did for writing headers. Will eventually allow libsndfile to read and write from pipes, including named pipes. 2001-07-16 Erik de Castro Lopo * MacOS/config.h Win32/config.h Attempted to bring these two files uptodate with src/config.h. As I don't have access to either of these systems support for them may be completely broken. 2001-06-18 Erik de Castro Lopo * src/float32.c Fixed bug for big endian processors that can't read 32 bit IEEE floats. Now tested on Intel x86 and UltraSparc processors. 2001-06-13 Erik de Castro Lopo * src/aiff.c Modified to allow REX files (from Propellorhead's Recycle and Reason programs) to be read. REX files are basically an AIFF file with slightly unusual sequence of chunks (AIFF files are supposed to allow any sequence) and some extra application specific information. Not yet able to write a REX file as the details of the application specific data is unknown. 2001-06-12 Erik de Castro Lopo * src/wav.c Fixed endian bug when reading PEAK chunk on big endian machines. * src/common.c Fixed endian bug when reading PEAK chunk on big endian machines with --enable-force-broken-float configure option. Fix psf_binheader_writef for (FORCE_BROKEN_FLOAT ||______) 2001-06-07 Erik de Castro Lopo * configure.in src/config.h.in Removed old CAN_READ_WRITE_x86_IEEE configure variable now that float capabilities are detected at run time. Added FORCE_BROKEN_FLOAT to allow testing of broken float code on machines where the processor can in fact handle floats correctly. * src/float32.c Rejigged code reading and writing of floats on broken processors. * m4/ Removed this directory and all its files as they are no longer needed. 2001-06-05 Erik de Castro Lopo * tests/peak_chunk_test.c New test to validate reading and writing of peak chunk. * examples/sfconvert Added -float32 option. * src/*.c Changed all error return values to negative values (ie the negative of what they were). * src/sndfile.c tests/error_test.c Modified to take account of the previous change. 2001-06-04 Erik de Castro Lopo * src/float32.c File renamed from wav_float.c and renamed function to something more general. Added runtime detection of floating point capabilities. Added recording of peaks during write for generation of PEAK chunk. * src/wav.c src/aiff.c Added handing for PEAK chunk for floating point files. PEAK is read when the file headers are read and generated when the file is closed. Logic is in place for adding PEAK chunk to end of file when writing to a pipe (reading and writing from/to pipe to be implemented soon). * src/sndfile.c Modified sf_signal_max () to use PEAK values if present. 2001-06-03 Erik de Castro Lopo * src/*.c Added pcm_read_init () and pcm_write_init () to src/pcm.c and removed all other calls to functions in this file from the filetype specific files. * src/*.c Added alaw_read_init (), alaw_write_int (), ulaw_read_init () and ulaw_write_init () and removed all other calls to functions in alaw.c and ulaw.c from the filetype specific files. * tests/write_read_test.c Added tests to validate sf_seek () on all file types. * src/raw.c Implemented raw_seek () function to fix a bug where sf_seek (file, 0, SEEK_SET) on a RAW file failed. * src/paf.c Fixed a bug in paf24_seek () found due to added seeks tests in tests/write_read_test.c 2001-06-01 Erik de Castro Lopo * tests/read_seek_test.c Fixed a couple of broken binary files. * src/aiff.c src/wav.c Added handling of PEAK chunks on file read. 2001-05-31 Erik de Castro Lopo * check_libsndfile.py New file for the regression testing of libsndfile. check_libsndfile.py is a Python script which reads in a file containing filenames of audio files. Each file is checked by running the examples/sfinfo program on them and checking for error or warning messages in the libsndfile log buffer. * check_libsndfile.list This is an example list of audio files for use with check_libsndfile.py * tests/lossy_comp_test.c Changed the defined value of M_PI for math header files which don't have it. This fixed validation test failures on MetroWerks compilers. Thanks to Lord Praetor Satanus of Acheron for bringing this to my attention. 2001-05-30 Erik de Castro Lopo * src/common.[ch] Removed psf_header_setf () which was no longer required after refactoring and simplification of header writing. Added 'z' format specifier to psf_binheader_writef () for zero filling header with N bytes. Used by paf.c and nist.c * tests/check_log_buffer.c New file implementing check_log_buffer () which reads the log buffer of a SNDFILE* object and searches for error and warning messages. Calls exit () if any are found. * tests/*.c Added calls to check_log_buffer () after each call to sf_open_XXX (). 2001-05-29 Erik de Castro Lopo * src/wav.c src/wav_ms_adpcm.c src/wav_gsm610.c Major rehack of header writing using psf_binheader_writef (). 2001-05-28 Erik de Castro Lopo * src/wav.c src/wav_ima_adpcm.c Major rehack of header writing using psf_binheader_writef (). 2001-05-27 Erik de Castro Lopo * src/wav.c Changed return type of get_encoding_str () to prevent compiler warnings on Mac OSX. * src/aiff.c src/au.c Major rehack of header writing using psf_binheader_writef (). 2001-05-25 Erik de Castro Lopo * src/common.h src/common.c Added comments. Name of log buffer changed from strbuffer to logbuffer. Name of log buffer index variable changed from strindex to logindex. * src/*.[ch] Changed name of internal logging function from psf_sprintf () to psf_log_printf (). Changed name of internal header generation functions from psf_[ab]h_printf () to psf_asciiheader_printf () and psf_binheader_writef (). Changed name of internal header manipulation function psf_hsetf () to psf_header_setf (). 2001-05-24 Erik de Castro Lopo * src/nist.c Fixed reading and writing of sample_byte_format header. "01" means little endian and "10" means big endian regardless of bit width. * configure.in Detect Mac OSX and disable -Wall and -pedantic gcc options. Mac OSX is way screwed up and spews out buckets of warning messages from the system headers. Added --disable-gcc-opt configure option (sets gcc optimisation to -O0 ) for easier debugging. Made decision to harmonise source code version number and .so library version number. Future releases will stick to this rule. * doc/new_file_type.HOWTO New file to document the addition of new file types to libsndfile. 2001-05-23 Erik de Castro Lopo * src/nist.c New file for reading/writing Sphere NIST audio file format. Originally requested by Elis Pomales in 1999. Retrieved from unstable (and untouched for 18 months) branch of libsndfile. Some vital information gleaned from the source code to Bill Schottstaedt's sndlib library : ftp://ccrma-ftp.stanford.edu/pub/Lisp/sndlib.tar.gz Currently reading and writing 16, 24 and 32 bit, big-endian and little endian, stereo and mono files. * src/common.h src/common.c Added psf_ah_printf () function to help construction of ASCII headers (ie NIST). * configure.in Added test for vsnprintf () required by psf_ah_printf (). * tests/write_read_test.c Added tests for supported NIST files. 2001-05-22 Erik de Castro Lopo * tests/write_read_test.c Added tests for little endian AIFC files. * src/aiff.c Minor re-working of aiff_open_write (). Added write support for little endian PCM encoded AIFC files. 2001-05-13 Erik de Castro Lopo * src/aiff.c Minor re-working of aiff_open_read (). Added read support for little endian PCM encoded AIFC files from the Mac OSX CD ripper program. Guillaume Lessard provided a couple of sample files and a working patch. The patch was not used as is but gave a good guide as to what to do. 2001-05-11 Erik de Castro Lopo * src/sndfile.h Fixed comments about endian-ness of WAV and AIFF files. Guillaume Lessard pointed out the error. 2001-04-23 Erik de Castro Lopo * examples/make_sine.c Re-write of this example using sample rate and required frequency in Hz. 2001-02-11 Erik de Castro Lopo * src/sndfile.c Fixed bug that prevented known file types from being read as RAW PCM data. 2000-12-16 Erik de Castro Lopo * src/aiff.c Added handing of COMT chunk. 2000-11-16 Erik de Castro Lopo * examples/sfconvert.c Fixed bug in normalisatio code. Pointed out by Johnny Wu. 2000-11-08 Erik de Castro Lopo * Win32/config.h Fixed the incorrect setting of HAVE_ENDIAN_H parameter. Win32 only issue. 2000-10-27 Erik de Castro Lopo * tests/Makefile.am Added -lm for write_read_test_LDADD. 2000-10-16 Erik de Castro Lopo * src/sndfile.c src/au.c Fixed bug which prevented writing of G723 24kbps AU files. * tests/lossy_comp_test.c Corrrection to options for G723 tests. * configure.in Added --disable-gcc-pipe option for DJGPP compiler (gcc on MS-DOS) which doesn't allow gcc -pipe option. 2000-09-03 Erik de Castro Lopo * src/ulaw.c src/alaw.c src/wav_imaadpcm.c src/msadpcm.c src/wav_gsm610.c Fixed normailsation bugs shown up by new double_test program. 2000-08-31 Erik de Castro Lopo * src/pcm.c Fixed bug in normalisation code (spotted by Steve Lhomme). * tests/double_test.c New file to test scaled and unscaled sf_read_double() and sf_write_double() functions. 2000-08-28 Erik de Castro Lopo * COPYING Changed to the LGPL COPYING file (spotted by H. S. Teoh). 2000-08-21 Erik de Castro Lopo * src/sndfile.h Removed prototype of unimplemented function sf_get_info(). Added prototype for sf_error_number() Thanks to Sigbjørn Skjæret for spotting these. 2000-08-18 Erik de Castro Lopo * src/newpcm.h New file to contain a complete rewrite of the PCM data handling. 2000-08-15 Erik de Castro Lopo * src/sndfile.c Fixed a leak of FILE* pointers in sf_open_write(). Thanks to Sigbjørn Skjæret for spotting this one. 2000-08-13 Erik de Castro Lopo * src/au_g72x.c src/G72x/g72x.c Added G723 encoded AU file support. * tests/lossy_comp_test.c Added tests for G721 and G723 encoded AU files. 2000-08-06 Erik de Castro Lopo * all files Changed the license to LGPL. Albert Faber who had copyright on Win32/unistd.h gave his permission to change the license on that file. All other files were either copyright erikd AT mega-nerd DOT com or copyright under a GPL/LGPL compatible license. 2000-08-06 Erik de Castro Lopo * tests/lossy_comp_test.c Fixed incorrect error message. * src/au_g72x.c src/G72x/* G721 encoded AU files now working. * Win32/README-Win32.txt Replaced this file with a new one which gives a full explanation of how to build libsndfile under Win32. Thanks to Mike Ricos. 2000-08-05 Erik de Castro Lopo * src/*.[ch] Removed double leading underscores from the start of all variable and function names. Identifiers with a leading underscores are reserved for use by the compiler. * src/au_g72x.c src/G72x/* Continued work on G721 encoded AU files. 2000-07-12 Erik de Castro Lopo * src/G72x/* New files for reading/writing G721 and G723 ADPCM audio. These files are from a Sun Microsystems reference implementation released under a free software licence. Extensive changes to this code to make it fit in with libsndfile. See the ChangeLog in this directory for details. * src/au_g72x.c New file for G721 encoded AU files. 2000-07-08 Erik de Castro Lopo * libsndfile.spec.in Added a spec file for making RPMs. Thanks to Josh Green for supplying this. 2000-06-28 Erik de Castro Lopo * src/sndfile.c src/sndfile.h Add checking for and handling of header-less u-law encoded AU/SND files. Any file with a ".au" or ".snd" file extension and without the normal AU file header is treated as an 8kHz, u-law encoded file. * src/au.h New function for opening a headerless u-law encoded file for read. 2000-06-04 Erik de Castro Lopo * src/paf.c Add checking for files shorter than minimal PAF file header length. 2000-06-02 Erik de Castro Lopo * tests/write_read_test.c Added extra sf_perror() calls when sf_write_XXXX fails. 2000-05-29 Erik de Castro Lopo * src/common.c Modified usage of va_arg() macro to work correctly on PowerPC Linux. Thanks to Kyle Wheeler for giving me ssh access to his machine while I was trying to track this down. * configure.in src/*.[ch] Sorted out some endian-ness issues brought up by PowerPC Linux. * tests/read_seek_test.c Added extra debugging for when tests fail. 2000-05-18 Erik de Castro Lopo * src/wav.c Fixed bug in GSM 6.10 handling for big-endian machines. Thanks to Sigbjørn Skjæret for reporting this. 2000-04-25 Erik de Castro Lopo * src/sndfile.c src/wav.c src/wav_gsm610.c Finallised writing of GSM 6.10 WAV files. * tests/lossy_comp_test.c Wrote new test code for GSM 6.10 files. * examples/sfinfo.c Fixed incorrect format in printf() statement. 2000-04-06 Erik de Castro Lopo * src/sndfile.h.in Fixed comments about sf_perror () and sf_error_str (). 2000-03-14 Erik de Castro Lopo * configure.in Fixed --enable-justsrc option. 2000-03-07 Erik de Castro Lopo * wav.c Fixed checking of bytespersec field of header. Still some weirdness with some files. 2000-03-05 Erik de Castro Lopo * tests/lossy_comp_test.c Added option to test PCM WAV files (sanity check). Fixed bug in sf_seek() tests. 2000-02-29 Erik de Castro Lopo * src/sndfile.c src/wav.c Minor changes to allow writing of GSM 6.10 WAV files. 2000-02-28 Erik de Castro Lopo * configure.in Makefile.am src/Makefile.am Finally got around to figuring out how to build a single library from multiple source directories. Reading GSM 6.10 files now seems to work. 2000-01-03 Erik de Castro Lopo * src/wav.c Added more error reporting in read_fmt_chunk(). 1999-12-21 Erik de Castro Lopo * examples/sfinfo.c Modified program to accept multiple filenames from the command line. 1999-11-27 Erik de Castro Lopo * src/wav_ima_adpcm.c Moved code around in preparation to adding ability to read/write IMA ADPCM encoded AIFF files. 1999-11-16 Erik de Castro Lopo * src/common.c Fixed put_int() and put_short() macros used by _psf_hprintf() which were causing seg. faults on Sparc Solaris. 1999-11-15 Erik de Castro Lopo * src/common.c Added string.h to includes. Thanks to Sigbjxrn Skjfret. * src/svx.c Fixed __svx_close() function to ensure FORM and BODY chunks are correctly set. 1999-10-01 Erik de Castro Lopo * src/au.c Fixed handling of incorrect size field in AU header on read. Thanks to Christoph Lauer for finding this problem. 1999-09-28 Erik de Castro Lopo * src/aiff.c Fixed a bug with incorrect SSND chunk length being written. This also lead to finding an minor error in AIFF header parsing. Thanks to Dan Timis for pointing this out. 1999-09-24 Erik de Castro Lopo * src/paf.c Fixed a bug with reading and writing 24 bit stereo PAF files. This problem came to light when implementing tests for the new functions which operate in terms of frames rather than items. 1999-09-23 Erik de Castro Lopo * src/sndfile.c Modified file type detection to use first 12 bytes of file rather than file name extension. Required this because NIST files use the same filename extension as Microsoft WAV files. * src/sndfile.c src/sndfile.h Added short, int and double read/write functions which work in frames rather than items. This was originally suggested by Maurizio Umberto Puxeddu. 1999-09-22 Erik de Castro Lopo * src/svx.c Finished off implementation of write using __psf_hprintf(). 1999-09-21 Erik de Castro Lopo * src/common.h Added a buffer to SF_PRIVATE for writing the header. This is required to make generating headers for IFF/SVX files easier as well as making it easier to do re-write the headers which will be required when sf_rewrite_header() is implemented. * src/common.c Implemented __psf_hprintf() function. This is an internal function which is documented briefly just above the code. 1999-09-05 Erik de Castro Lopo * src/sndfile.c Fixed a bug in sf_write_raw() where it was returning incorrect values (thanks to Richard Dobson for finding this one). Must put in a test routine for sf_read_raw and sf_write_raw. * src/aiff.c Fixed default FORMsize in __aiff_open_write (). * src/sndfile.c Added copy of filename to internal data structure. IFF/SVX files contain a NAME header chunk. Both sf_open_read() and sf_open_write() copy the file name (less the leading path information) to the filename field. * src/svx.c Started implementing writing of files. 1999-08-04 Erik de Castro Lopo * src/svx.c New file for reading/writing 8SVX and 16SVX files. * src/sndfile.[ch] src/common.h Changes for SVX files. * src/aiff.c Fixed header parsing when unknown chunk is found. 1999-08-01 Erik de Castro Lopo * src/paf.c New file for reading/writing Ensoniq PARIS audio file format. * src/sndfile.[ch] src/common.h Changes for PAF files. * src/sndfile.[ch] Added stuff for sf_get_lib_version() function. 1999-07-31 Erik de Castro Lopo * src/sndfile.h MacOS/config.h Fixed minor MacOS configuration issues. 1999-07-30 Erik de Castro Lopo * MacOS/ Added a new directory for the MacOS config.h file and the readme file. * src/aiff.c Fixed calculation of datalength when reading SSND chunk. Thanks to Sigbjørn Skjæret for pointing out this error. 1999-07-29 Erik de Castro Lopo * src/sndfile.c src/sndfile.h src/raw.c Further fixing of #includes for MacOS. 1999-07-25 Erik de Castro Lopo * src/wav.c src/aiff.c Added call to ferror () in main header parsing loop of __XXX_open_read functions. This should fix problems on platforms (MacOS, AmigaOS) where fseek()ing or fread()ing beyond the end of the file puts the FILE* stream in an error state until clearerr() is called. * tests/write_read_test.c Added tests for RAW header-less PCM files. * src/common.h Moved definition of struct tribyte to pcm.c which is the only place which needs it. * src/pcm.c Modified all code which assumed sizeof (struct tribyte) == 3. This code did not work on MacOS. Thanks to Ben "Jacobs" for pointing this out. * src/au.c Removed from list of #includes (not being used). * src/sndfile.c Added MacOS specific #ifdef to replace . * src/sndfile.h Added MacOS specific #ifdef to replace . * src/sndfile.h Added MacOS specific typedef for off_t. * MacOS-readme.txt New file with instructions for building libsndfile under MacOS. Thanks to Ben "Jacobs" for supplying these instructions. 1999-07-24 Erik de Castro Lopo * configure.in Removed sndfile.h from generated file list as there were no longer any autoconf substitutions being made. * src/raw.c New file for handling raw header-less PCM files. In order to open these for read, the user must specify format, pcmbitwidth and channels in the SF_INFO struct when calling sf_open_read (). * src/sndfile.c Added support for raw header-less PCM files. 1999-07-22 Erik de Castro Lopo * examples/sfinfo.c Removed options so the sfinfo program always prints out all the information. 1999-07-19 Erik de Castro Lopo * src/alaw.c New file for A-law encoding (similar to u-law). * tests/alaw_test.c New test program to test the A-law encode/decode lookup tables. * tests/lossy_comp_test.c Added tests for a-law encoded WAV, AU and AULE files. 1999-07-18 Erik de Castro Lopo * src/sndfile.c src/au.c Removed second "#include ". Thanks to Ben "Jacobs" for pointing this out. 1999-07-18 Erik de Castro Lopo * tests/ulaw_test.c New test program to test the u-law encode/decode lookup tables. 1999-07-16 Erik de Castro Lopo * src/sndfile.h Made corrections to comments on the return values from sf_seek (). * src/sndfile.c Fixed boundary condition checking bug and accounting bug in sf_read_raw (). 1999-07-15 Erik de Castro Lopo * src/au.c src/ulaw.c Finished implementation of u-law encoded AU files. * src/wav.c Implemented reading and writing of u-law encoded WAV files. * tests/ Changed name of adpcm_test.c to lossy_comp_test.c. This test program will now be used to test Ulaw and Alaw encoding as well as APDCM. Added tests for Ulaw encoded WAV files. 1999-07-14 Erik de Castro Lopo * tests/adpcm_test.c Initialised amp variable in gen_signal() to remove compiler warning. 1999-07-12 Erik de Castro Lopo * src/aiff.c In __aiff_open_read () prevented fseek()ing beyond end of file which was causing trouble on MacOS with the MetroWerks compiler. Thanks to Ben "Jacobs" for pointing this out. *src/wav.c Fixed as above in __wav_open_read (). 1999-07-01 Erik de Castro Lopo * src/wav_ms_adpcm.c Implemented MS ADPCM encoding. Code cleanup of decoder. * tests/adpcm_test.c Added tests for MS ADPCM WAV files. * src/wav_ima_adpcm.c Fixed incorrect parameter in call to srate2blocksize () from __ima_writer_init (). 1999-06-23 Erik de Castro Lopo * tests/read_seek_test.c Added test for 8 bit AIFF files. 1999-06-18 Erik de Castro Lopo * tests/write_read_test.c Removed test for IMA ADPCM WAV files which is now done in adpcm_test.c * configure.in Added -Wconversion to CFLAGS. * src/*.c tests/*.c examples/*.c Fixed all warnings resulting from use of -Wconversion. 1999-06-17 Erik de Castro Lopo * src/wav.c Added fact chunk handling on read and write for all non WAVE_FORMAT_PCM WAV files. * src/wav_ima.c Changed block alignment to be dependant on sample rate. This should make WAV files created with libsndfile compatible with the MS Windows media players. * tests/adpcm_test.c Reimplemented adpcm_test_short and implemented adpcm_test_int and adpcm_test_double. Now have full testing of IMA ADPCM WAV file read, write and seek. 1999-06-15 Erik de Castro Lopo * src/wav_float.c Fixed function prototype for x86f2d_array () which was causing ocassional seg. faults on Sparc Solaris machines. 1999-06-14 Erik de Castro Lopo * src/aiff.c Fixed bug in __aiff_close where the length fields in the header were not being correctly calculated before writing. * tests/write_read_test.c Modified to detect the above bug in WAV, AIFF and AU files. 1999-06-12 Erik de Castro Lopo * Win32/* Added a contribution from Albert Faber to allow libsndfile to compile under Win32 systems. libsndfile will now be used as part of LAME the the MPEG 1 Layer 3 encoder (http://internet.roadrunner.com/~mt/mp3/). 1999-06-11 Erik de Castro Lopo * configure.in Changed to reflect previous changes. * src/wav_ima_adpcm.c Fixed incorrect calculation of bytespersec header field (IMA ADPCM only). Fixed bug when writing from int or double data to IMA ADPCM file. Will need to write test code for this. Fixed bug in __ima_write () whereby the length of the current block was calculated incorrectly. Thanks to Jongcheon Park for pointing this out. 1999-03-27 Erik de Castro Lopo * src/*.c Changed all read/write/lseek function calls to fread/fwrite/ fseek/ftell and added error checking of return values from fread and fwrite in critical areas of the code. * src/au.c Fixed incorrect datasize element in AU header on write. * tests/error_test.c Add new test to check all error values have an associated error string. This will avoid embarrassing real world core dumps. 1999-03-23 Erik de Castro Lopo * src/wav.c src/aiff.c Added handling for unknown chunk markers in the file. 1999-03-22 Erik de Castro Lopo * src/sndfile.c Filled in missing error strings in SndfileErrors array. Missing entries can cause core dumps when calling sf_error-str (). Thanks to Sam for finding this problem. 1999-03-21 Erik de Castro Lopo * src/wav_ima_adpcm.c Work on wav_ms_adpcm.c uncovered a bug in __ima_read () when reading stereo files. Caused by not adjusting offset into buffer of decoded samples for 2 channels. A similar bug existed in __ima_write (). Need a test for stereo ADPCM files. * src/wav_ms_adpcm.c Decoder working correctly. 1999-03-18 Erik de Castro Lopo * configure.in Makefile.am Added --enable-justsrc configuration variable sent by Sam . * src/wav_ima_adpcm.c Fixed bug when reading beyond end of data section due to not checking pima->blockcount. This uncovered __ima_seek () bug due to pima->blockcount being set before calling __ima_init_block (). 1999-03-17 Erik de Castro Lopo * src/wav.c Started implementing MS ADPCM decoder. If file is WAVE_FORMAT_ADPCM and length of data chunk is odd, this encoder seems to add an extra byte. Why not just give an even data length? 1999-03-16 Erik de Castro Lopo * src/wav.c Split code out of wav.c to create wav_float.c and wav_ima_adpcm.c. This will make it easier to add and debug other kinds of WAV files in future. 1999-03-14 Erik de Castro Lopo * tests/ Added adpcm_test.c which implements test functions for IMA ADPCM reading/writing/seeking etc. * src/wav.c Fixed many bugs in IMA ADPCM encoder and decoder. 1999-03-11 Erik de Castro Lopo * src/wav.c Finished implementing IMA ADPCM encoder and decoder (what a bitch!). 1999-03-03 Erik de Castro Lopo * src/wav.c Started implementing IMA ADPCM decoder. 1999-03-02 Erik de Castro Lopo * src/sndfile.c Fixed bug where the sf_read_XXX functions were returning a incorrect read count when reading past end of file. Fixed bug in sf_seek () when seeking backwards from end of file. * tests/read_seek_test.c Added multiple read test to short_test(), int_test () and double_test (). Added extra chunk to all test WAV files to test that reading stops at end of 'data' chunk. 1999-02-21 Erik de Castro Lopo * tests/write_read_test.c Added tests for little DEC endian AU files. * src/au.c Add handling for DEC format little endian AU files. 1999-02-20 Erik de Castro Lopo * src/aiff.c src/au.c src/wav.c Add __psf_sprintf calls during header parsing. * src/sndfile.c src/common.c Implement sf_header_info (sndfile.c) function and __psf_sprintf (common.c). * tests/write_read_test.c Added tests for 8 bit PCM files (WAV, AIFF and AU). * src/au.c src/aiff.c Add handling of 8 bit PCM data format. * src/aiff.c On write, set blocksize in SSND chunk to zero like everybody else. 1999-02-16 Erik de Castro Lopo * src/pcm.c: Fixed bug in let2s_array (cptr was not being initialised). * src/sndfile.c: Fixed bug in sf_read_raw and sf_write_raw. sf_seek should now work when using these functions. 1999-02-15 Erik de Castro Lopo * tests/write_read_test.c: Force test_buffer array to be double aligned. Sparc Solaris requires this. 1999-02-14 Erik de Castro Lopo * src/pcm.c: Fixed a bug which was causing errors in the reading and writing of 24 bit PCM files. * doc/api.html Finished of preliminary documentaion. 1999-02-13 Erik de Castro Lopo * src/aiff.c: Changed reading of 'COMM' chunk to avoid reading an int which overlaps an int (4 byte) boundary. libsndfile-1.0.28/doc/libsndfile.css.in0000644000175000017500000000342012677561544014655 00000000000000body { background : @HTML_BGCOLOUR@ ; color : @HTML_FGCOLOUR@ ; font-family : arial, helvetica, sans-serif ; line-height: 1.5 ; } td { font-family : arial, helvetica, sans-serif ; background : @HTML_BGCOLOUR@ ; color : @HTML_FGCOLOUR@ ; } center { font-family : arial, helvetica, sans-serif ; } p { font-family : arial, helvetica, sans-serif ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } .indent_block { font-family : arial, helvetica, sans-serif ; text-align : left ; margin-left : 10% ; margin-right : 10% ; } br { font-family : arial, helvetica, sans-serif ; } form { font-family : arial, helvetica, sans-serif ; } ul { font-family : arial, helvetica, sans-serif ; text-align : left ; margin-left : 3% ; margin-right : 6% ; } ol { font-family : arial, helvetica, sans-serif ; text-align : left ; margin-left : 3% ; margin-right : 6% ; } dl { font-family : arial, helvetica, sans-serif ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } h1 { font-size : xx-large ; background : @HTML_BGCOLOUR@ ; color : #5050FF ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } h2 { font-size : x-large ; background : @HTML_BGCOLOUR@ ; color : #5050FF ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } h3 { font-size : large ; background : @HTML_BGCOLOUR@ ; color : #5050FF ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } h4 { font-size : medium ; background : @HTML_BGCOLOUR@ ; color : #5050FF ; text-align : left ; margin-left : 3% ; margin-right : 3% ; } pre { font-family : courier, monospace ; font-size : medium ; margin-left : 6% ; margin-right : 6% ; } a:link { color : #9090FF ; } a:visited { color : #5050FF ; } a:active { color : #FF00FF ; } a:hover { background-color : #202080 ; } libsndfile-1.0.28/doc/embedded_files.html0000644000175000017500000000264111704512754015215 00000000000000 libsndfile : Embedded Sound Files.

Embedded Sound Files.

By using the open SNDFILE with a file descriptor function: 

      SNDFILE*  sf_open_fd (int fd, int mode, SF_INFO *sfinfo, int close_desc) ;

it is possible to open sound files embedded within larger files. There are however a couple of caveats:

  • Read/Write mode (SFM_RDWR) is not supported.
  • Writing of embedded files is only supported at the end of the file.
  • Reading of embedded files is only supported at file offsets greater than zero.
  • Not all file formats are supported (currently only WAV, AIFF and AU).

The test program multi_file_test.c in the tests/ directory of the source code tarball shows how this functionality is used to read and write embedded files.

This can be achieved as follows: 1) In a CMD window, change to the directory containing this file and run the command: lib /machine:i386 /def:libsndfile-1.def You now have two files: libsndfile-1.dll libsndfile-1.lib to be used with VisualStudio. If the lib command fails with a command saying "'lib' is not recognized as an internal or external command, operable program or batch file", you need to find the location of "lib.exe" and add that directory to your PATH environment variable. Another alternative is to use the "Visual Studio 2005 Command Prompt" Start menu item: Start -> All Programs -> Visual Studio 2005 -> Visual Studio Tools -> Visual Studio 2005 Command Prompt If for some reason these instructions don't work for you or you are still not able to use the libsndfile DLL with you project, please do not contact the main author of libsndfile. Instead, join the libsndfile-users mailing list : http://www.mega-nerd.com/libsndfile/lists.html and ask a question there.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell command `./configure && make && make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf limitation. Until the limitation is lifted, you can use this workaround: CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details.
