There is a python script in the test/ directory which will compare two versions of lame using a bunch of CBR and ABR options. To run this script, copy your favorite (and short!) wav file to the lame/test directory, and run: % cd lame/test % ./lametest.py [-w] CBRABR.op castanets.wav lame_orig lame_new ************************************************************************ LAME API ======== For a general outline of the code, see the file API. Also, frontend/main.c is a simple front end to libmp3lame.a The guts of the code are called from lame_encode_buffer(). lame_encode_buffer() handles buffering and resampling, and then calls lame_encode_frame() for each frame. lame_encode_frame() looks like this: lame_encode_frame_mp3(): l3psycho_anal() compute masking thresholds mdct_sub() compute MDCT coefficients iteration_loop() choose scalefactors (via iteration) which determine noise shapping, and choose best huffman tables for lossless compression format_bitstream format the bitstream. when data+headers are complete, output to internal bit buffer. copy_buffer() copy internal bit buffer into user's mp3 buffer ************************************************************************ ADDING NEW OPTIONS ================== control variable goes in lame_global_flags struct. Assume the variable is called 'new_variable'. You also need to write (in set_get.c): lame_set_new_variable() lame_get_new_variable() And then document the variable in the file USAGE as well as the output of "lame --longhelp" And add a "--option" style command line option to enable this variable in parse.c Note: for experimental features that you need to call from the frontend but that should not be part of the official API, see the section at the end of set_get.c. These functions should *NOT* be prototyped in lame.h (since that would indicate to the world that they are part of the API). ************************************************************************ THREADSAFE: =========== Lame should now be thread safe and re-entrant. The only problem seems to be some OS's allocate small stacks (< 128K) to threads launched by applications, and this is not enough for LAME. Fix is to increase the stack space, or move some of our automatic variables onto the heap with by using bug-proof malloc()'s and free(). ************************************************************************ Global Variables: ================= There are two types of global variables. All data in both structs is initialized to zero. 1. lame_global_flags *gfp These are input parameters which are set by the calling program, and some information which the calling program may be interested in. This struct instantiated by the call to lame_init(). 2. lame_internal_flags *gfc Most global variables go here. All internal data not set by the user. All 'static' data from old non-reentrant code should be moved here. Defined in util.h. Data for which the size is known in advance should be explicitly declaired (for example, float xr[576]); Data which needs to be malloc'd is handled by: 1. in lame_init_params(), malloc the data 2. be sure to free the data in freegfc() If the data to be malloc'd is large and only used in certain conditions (like resampling), use the following: this has the disadvantage that it is hard to catch and return error flags all the way back up the call stack. 1. Add an initialization variable to the gfc struct: lame_init_resample 2. In the resample routine, there should be some code like this: if (0==gfc->lame_init_resample) { gfc->lame_init_resample=1; /* initialization code: malloc() data, etc */ } 3. The data should be free'd in the routine freegfc(). lame-3.100/aclocal.m4000644 001751 001751 00001537106 13144610167 015743 0ustar00netchildnetchild000000 000000 # generated automatically by aclocal 1.15.1 -*- Autoconf -*- # Copyright (C) 1996-2017 Free Software Foundation, Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Thanks to Maks Naumov and Fabian Greffrath for the contribution. 2015-04-28 22:07 rbrito * libmp3lame/util.c: libmp3lame: Fix decision if sample rate ratio is an integer value or not. From Fabian Greffrath's original description: If the sample rate of the input file is sufficiently close to an integer multiple of the output sample rate, the value of the intratio variable is calculated incorrectly. This leads to further values being miscalculated up to the joff variable which is used as an index to dereference the esv->blackfilt array. This leads top an overflow and causes a segmentation fault.

This will allow third-party encoding applications using the DirectShow System Device Enumerator Interface to correctly detect the LAME encoder when querying the Audio Compressors filter group. - Modified the filter registration information so that the MP3 audio subtype is correctly reported as being supported on the encoder output pin. This will allow third-party encoding applications using the DirectShow IFilterMapper2 Interface to recognize that the LAME encoder supports MP3 output. - Altered the Filter Merit Value that was being used when the filter was registered so that it is now using the standard DirectShow compressor filter merit value of MERIT_DO_NOT_USE (0x200000). Previously, the filter was being registered using a value of MERIT_SW_COMPRESSOR (0x100000), which was at a lower priority (i.e. worse priority) than MERIT_DO_NOT_USE. This prevented the LAME Encoder filter from being selected for use by some third-party encoding applications. - Added code to calculate the frame length of the audio frames used for the nBlockSize element of the WAVEFORMATEX output structure. Previously this value was simply hard-coded to 1. 2009-04-11 15:51 jwflynn1 * dshow/Mpegac.h: Added support for the DirectShow IAMStreamConfig Interface 2009-04-11 15:47 jwflynn1 * dshow/Property.rc: Updated the embedded "FileVersion" and "ProductVersion" fields 2009-03-31 22:37 robert * libmp3lame/: util.c, util.h (lame3_98), util.c, util.h: fix for tracker item 2723518: resampling in 3.98 and 3.99alpha 2009-03-30 19:48 robert * libmp3lame/lame.c (lame3_98): ensure we padd at least 288 samples 2009-03-30 14:38 robert * libmp3lame/lame.c: ensure we pad with 288 samples at least 2009-03-30 13:42 robert * frontend/: main.c, main.h, parse.c: commandline option "--swap-channel" added, as requested. see item: 1118412 2009-03-29 18:28 robert * libmp3lame/psymodel.c: take away sandpaper safety margin for lower samplerates.

The change involves the call to snprintf() in libmp3lame/id3tag.c., but snprintf() is not available on many of these platforms. I know that in general replacing snprintf() with sprintf() removes a layer of string buffer overflow protection, but in this case it should be safe because the size of string is bounded. ---snip--- 2004-01-31 20:05 olcios * testcase.mp3, frontend/main.c, libmp3lame/lame.c: disabled peak sample detection when LAME tag is not written into the file 2004-01-29 16:39 bouvigne * doc/html/history.html: history 2004-01-29 16:31 bouvigne * libmp3lame/version.h: bump alpha because of the fixed crashes 2004-01-29 16:26 bouvigne * libmp3lame/takehiro.c: fixed bug #886989 2004-01-26 14:00 olcios * USAGE, doc/html/switchs.html, doc/man/lame.1, frontend/parse.c: updated documentation and --longhelp on RG 2004-01-26 12:05 olcios * frontend/main.c, frontend/main.h, frontend/parse.c, include/lame.h, libmp3lame/VbrTag.c, libmp3lame/VbrTag.h, libmp3lame/bitstream.c, libmp3lame/lame.c, libmp3lame/set_get.c, libmp3lame/util.h: removed ReportLameTagProgress (it is not LAME API).

Because sometimes I have the urge to try something with the sourcecode. I'd like to add a switch to avoid the use of --scale for preventing clipping. It manipulates global_gain, similar as the mp3gain tool does, but this would be much more convenient of course (and better quality-wise, being 'lossless'). Since I have no programming experience, can you take a look if I implemented it correctly? The switch is called --gglower x, where each x-step stands for 1,5 dB. gg is short for global gain. So for example, --gglower 1 will decrease the output volume with 1,5 dB (0,841). I would probably use this by default, it will be enough to prevent clipping for all but the oddest samples/settings. I did a lot of copy/pasting from the --athlower switch, otherwise I probably couldn't figure it all out! Files involved are parse.c, lame_global_flags.h, set_get.c, lame.h and bitstream.c. I attached these files, if you search in each for 'gglower' you'll find the added code. Files came from the 11 Nov CVS. Also attached is a cygwin lame.exe if you like to play with it. Let's add it to CVS if it's OK (don't know how to do that myself, have to tell Mark?).

This code: if( h_id == 0 ) pTagData->samprate >>= 1; was, for unknown reasons, cutting the samplrate down by a factor of two for MPEG2, causing the framesize of the Xing header to be too large, causing it to overwrite the first valid MP3 frame. 2001-10-25 11:54 roelvdb * libmp3lame/VbrTag.c: undo previous edit, misunderstanding 2001-10-24 23:59 roelvdb * libmp3lame/VbrTag.c: if ABR, {store bitrate <=255} else { use 4 low bits to store bitrateindex so "-b" for VBR(/CBR) is known. 0F for freeformat} 2001-10-24 20:45 markt * testcase.mp3: updated testcases 2001-10-24 16:33 aleidinger * doc/man/lame.1: sync with HTML 2001-10-24 12:44 bouvigne * doc/html/: basic.html, examples.html, history.html, node6.html, switchs.html: doc fixes 2001-10-24 12:32 bouvigne * doc/html/switchs.html: a small athtype doc modif 2001-10-23 16:35 bouvigne * doc/html/switchs.html: fixes from Dmitry 2001-10-23 16:17 bouvigne * doc/html/switchs.html: fixes from Alexander 2001-10-23 14:06 aleidinger * doc/man/lame.1: add line breaks, expand examples section, add ID3 section, fixes 2001-10-23 14:06 aleidinger * frontend/main.c: fix for cygwin/mingw from egor duda 2001-10-22 21:31 roelvdb * libmp3lame/VbrTag.c: no message 2001-10-22 13:25 aleidinger * doc/man/lame.1: update based on HTML version 2001-10-21 17:00 bouvigne * doc/html/: basic.html, switchs.html: doc 2001-10-20 16:32 aleidinger * Makefile.unix: Submitted by: "Vladislav Naumov" I canged number 2 of his fixes to be equal to configure.in (-O3 is the highest official supportes optimization option, some of the options are superfluous (because they are included in -O3), some may perhaps change the ABI (ABI, not API!), e.g. -malign-*).

Changed the default in configure.in to define HAVE_VORBIS 2. HAVE_VORBIS_ENCODER This is the code which hasn't compiled since Vorbis beta1.

I guess the final verdict is tough luck :-) 2001-06-04 23:29 markt * API, HACKING, frontend/parse.c, libmp3lame/lame.c: print error message and fail if user selects error_protection (since this is currently broken) added some comments to HACKING on how to add a new option. updated API to reflect that all lame_set/get functions are now working. 2001-06-04 23:10 markt * include/lame.h, libmp3lame/lame.c: updated comments about lame_encode_flush_nogap() 2001-06-04 23:08 markt * include/lame.h, libmp3lame/bitstream.c, libmp3lame/lame.c: added lame_encode_flush_nogap(). This routine will flush all internal mp3 buffers, and pad the last frame with ancillary data so it is a complete mp3 frame. It will then set ResvSize to 0, so we can continue encoding. after a call to lame_encode_flush_nogap(), if we close the mp3 file and open a new one for the future data, then the two mp3 files should play back 'gapless' if they are first concatenated together. 2001-06-04 19:59 robert * frontend/parse.c, libmp3lame/lame.c, libmp3lame/quantize.c, libmp3lame/version.h: tweaks to VBR 2001-06-04 10:02 afaber * Dll/: BladeMP3EncDLL.c, BladeMP3EncDLL.h: Extended interface with VBR method selection 2001-06-04 10:01 afaber * mpglib/layer3.c: Removed exit call(s) in error conditions, since these errors seems to be good recoverable 2001-06-04 01:54 robert * libmp3lame/: lame.c, psymodel.c, quantize.c, util.h: small tweaks to the VBR codes 2001-06-02 20:22 robert * libmp3lame/: lame.c, quantize.c, util.h, version.h: started different bit-pressure strategies (VBR) 2001-06-02 15:26 aleidinger * configure: regen 2001-06-02 15:25 aleidinger * configure.in: force cygwin users to use "CC=gcc ./configure" 2001-06-01 19:40 glessard * frontend/get_audio.c: Added support for non-compressed AIFF-C files in parse_aiff_header(). 2001-05-30 01:38 markt * configure, configure.in: removed -pedantic gcc option.

We need to replace this with JD's formula. We need to decide if this is really worth while. My preference is to take the most conservative ATH possible, but this seems to produce too high bitrates for VBR modes. (this may no longer be true not that masings are computed in all scalefactor bands) 2001-03-10 18:33 markt * frontend/get_audio.c: added 127 also, on recommendation of JD, to 8bit -> 16bit conversion routine 2001-03-10 18:29 markt * frontend/get_audio.c: fix from "J.D." for 8 bit input support. 2001-03-09 17:56 markt * test/lametest.py: 'os.pathsep' changed to 'os.sep' For example, on unix: os.pathsep = ":" - the character that seperaters search paths in the PATH environment variable os.sep = "/" - the charcter that seperates directories 2001-03-07 12:32 aleidinger * test/lametest.py: - use OS independent path seperator 2001-03-07 12:31 aleidinger * DEFINES: - NOTABELS is now the default 2001-03-05 20:29 markt * libmp3lame/: lame.c, psymodel.c, quantize_pvt.c: code (disabled) to use minimum value when going from partition bands to scalefactor bands (instead of average value) 2001-03-05 18:21 markt * testcase.mp3, libmp3lame/psymodel.c, libmp3lame/quantize_pvt.c: Noise calculation: had to switch calculation of tot_noise and over_noise back to being done in db units. Multiply (to save the 22 log10() function calls) was overflowing. updated testcases to reflect changes 2001-03-05 01:44 markt * testcase.mp3: updated testcase.mp3 for NOTABLES code 2001-03-05 01:26 markt * libmp3lame/psymodel.c: NOTABLES enabled by default.

Will now compute masking for all scalefactor bands 2001-03-04 15:30 markt * testcase.mp3, libmp3lame/psymodel.c, libmp3lame/util.c: Finished proper normalization of spreading function. updated testcases 2001-03-04 06:56 markt * libmp3lame/psymodel.c: more tweaking of s3 normalization 2001-03-04 06:48 markt * libmp3lame/psymodel.c: spreading function moved into seperate routine, s3_func(). s3 normalized so that: +inf / | s3 [ bark ] d(bark) = 1 / -inf which resulted in dividing the result by 0.66. This is the first step in fixing the long outstanding bug mentioned by Takehiro: s3[i][j] is normalized improperly for values of i near the partition band boundaries. For these values, the computed 'norm' is much too small since a lot of the data is missing, resulting in artificially increasing the spreading function (and thus the masking) --nspsytune: s3_l function is used with a normalization of .5 (instead of computing the norm). So I changed this to a .5*.66 to compensate for the above change. Next step: 1. s3[i][j] will be multiplied by the width (in barks) of the j'th partition band (about .35). Once this is done, we will not need to compute and divide by 'norm' later. 2. Make NOTABLES the default 3. compute psymodel all the way up to 22khz. 2001-03-04 05:51 markt * API, libmp3lame/lame.c, libmp3lame/util.c, libmp3lame/util.h: added prototypes to lame.c (but functions not yet written) 2001-03-04 05:13 markt * include/lame.h: finished last of the prototypes 2001-03-04 05:02 markt * frontend/get_audio.c: changed to: gfp->num_samples = data_length / (channels * ((bits_per_sample+7) / 8)); thanks J.D.! 2001-03-04 00:20 markt * include/lame.h, libmp3lame/lame.c: added: lame_encode_buffer_sample_t, which is called by the following functions in the API: lame_encode_buffer (original, short int interface) lame_encode_buffer_float lame_encode_buffer_long 2001-03-02 22:39 markt * frontend/get_audio.c, test/lametest.py: get_audio.c: fixed num_samples computation for case when bits_per_sample < 8.

If you want to disable all internal library messages, set these to NULL with lame_set_errorf(), lame_set_msgf() etc... For a GUI, you can set these to regular files, and then read the files and display the messages in an pop up window. Maybe the default should be NULL? 2001-02-27 05:17 markt * include/lame.h: plugging away at a few more prototypes 2001-02-26 22:45 robert * frontend/parse.c, libmp3lame/util.c: little change to Roel's --r3mix setting, on request by Roel 2001-02-26 19:08 markt * libmp3lame/VbrTag.c: non RH_SEEKTABLE code removed from VbrTag.c 2001-02-26 18:57 markt * frontend/lametime.c: removed to //include lines 2001-02-26 18:52 markt * frontend/: get_audio.c, lametime.c: incomprehensible gobbledygook replaced by call to standard 'stat' function for file size. 2001-02-26 08:06 markt * include/lame.h: more prototypes added to lame.h 2001-02-26 07:38 markt * USAGE, frontend/parse.c, libmp3lame/lame.c: useTemporal turned on by default --notemp option added. 2001-02-26 07:26 markt * include/lame.h: added more of the lame_get/lame_set prototypes to lame.h also added this: // I give up. Klemm has worn me down on this one... typedef lame_global_flags lame_t; 2001-02-26 06:34 markt * misc/Lame.vbs: lame.vbs changes submitted by "Paul Reedy" 2001-02-25 22:47 markt * libmp3lame/vorbis_interface.c: removed a klemm_42 from vorbis_interface.c 2001-02-25 22:47 markt * INSTALL, libmp3lame/lame.c, libmp3lame/vorbis_interface.c: klemm_42 enabled by default. This code uses a different formula to choose the lowpass filter. It takes into account stereo vs. jstereo (jstereo gets 25% more bandwidth). This has the effect of stereo 128kbps using a 14khz lowpass filter, which some people may not like. 2001-02-25 22:02 markt * libmp3lame/lame.c, test/CBRABR.op: made allow_diff_short the default if mode=stereo and allow_diff_short has not been set to 0 or 1 by the calling program. addes these notes to lame_init_params() : * * We first have some complex code to determine bitrate, * output samplerate and mode. It is complicated by the fact * that we allow the user to set some or all of these parameters, * and need to determine best possible values for the rest of them: * * set some CPU related flags * check if we are mono->mono, stereo->mono or stereo->stereo * compute bitrate and output samplerate: * user may have set compression ratio * user may have set a bitrate * user may have set a output samplerate * set some options which depend on output samplerate * compute the actual compression ratio * set mode based on compression ratio * * The remaining code is much simpler - it just sets options * based on the mode & compression ratio: * * set allow_diff_short based on mode * select lowpass filter based on compression ratio & mode * set the bitrate index, and min/max bitrates for VBR modes * disable VBR tag if it is not appropriate * initialize the bitstream * initialize scalefac_band data * set sideinfo_len (based on channels, CRC, out_samplerate) * write an id3v2 tag into the bitstream * write VBR tag into the bitstream * set mpeg1/2 flag * estimate the number of frames (based on a lot of data) * * now we set more flags: * nspsytune: * see code * VBR modes * see code * CBR/ABR * see code 2001-02-25 21:28 markt * frontend/parse.c: removed VBR warning 2001-02-25 20:24 markt * libmp3lame/psymodel.c: edited a few comments in psymodel.c 2001-02-25 20:17 markt * libmp3lame/encoder.c, libmp3lame/psymodel.c, libmp3lame/psymodel.h, libmp3lame/util.h, test/nores.op: Started some re-originization of psymodel.c created: psymodel_init() function, called by both psymodel and psymodel_ns. I was carefull to make sure no binary changes were introduced with --nspsytune. Modified both psymodel and psymodel_ns to return the energy in each channel. I'm going to request that the ATH level adjust be based on the energy comptuted by the psymodel, rather than computing a magnitude in encoder.c 2001-02-25 17:37 markt * Dll/BladeMP3EncDLL.c, frontend/parse.c, include/lame.h, libmp3lame/lame.c, libmp3lame/util.c, libmp3lame/util.h: removed mode_fixed variable. If calling program selects a mode (mono, stereo, jstereo) then that mode is used, otherwise lame picks best mode to use. 2001-02-25 01:58 markt * include/lame.h: started adding more prototypes into lame.h: int lame_set_variable_name(lame_global_flags *, int) int lame_get_variable_name(lame_global_flags *) _get will return the value (instead of an error code) as suggested. _set will return an error code. But right now, the way lame works there is no error checking until lame_init_params() is called. This is because, for example, bitrate=135 is not an error if free_format=1, but it is an error for CBR. So many errors cannot be detected until all options are set. 2001-02-24 19:35 markt * include/lame.h, libmp3lame/util.h: commented out a uint_64_t field in util.h to get lame to compile. Do we really need these types of variables? removed some stuff from lame.h. Note that many decisions have already been made about the library interface, so if you are planning on changing this, you need to check with me (mark taylor) first. In particular, there is going to be no file I/O, and all data is in machine order. (no endian stuff in the library). 2001-02-24 13:55 robert * Makefile.unix, configMS.h: get Makefile.unix working again (tested for Linux, not for OS/2 etc.) 2001-02-21 21:17 robert * libmp3lame/lame.c: --vbr-mtrh related 2001-02-21 17:07 robert * libmp3lame/vbrquantize.c: take sfb21 into consideration for median search 2001-02-21 17:06 robert * libmp3lame/util.c: index transformation in select_kth_int() 2001-02-21 14:59 aleidinger * test/lametest.py: do not print the passed/failed statistic in the makeref case 2001-02-21 13:49 robert * frontend/parse.c, libmp3lame/lame.c: default quality handling fix 2001-02-21 12:39 aleidinger * Dll/BladeMP3EncDLL.c: lame.h has to be included before version.h 2001-02-20 18:34 aleidinger * Makefile.in, config.h.in, configure, configure.in, frontend/brhist.c: - Patch (#103821) from guy_hutchison: Fixes compilation problem on systems with ncurses dir - add ChangeLog to Makefile.in 2001-02-20 18:23 aleidinger * libmp3lame/: encoder.h, version.h: [no log message] 2001-02-20 18:20 aleidinger * doc/html/: Makefile.am, Makefile.in: - add basic.html 2001-02-20 18:20 aleidinger * configMS.h: - add LAME_LIBRARY_BUILD 2001-02-20 18:20 aleidinger * libmp3lame/util.h: - more documentation, seems to be partially truncated (Frank) - CPU_features is now a struct 2001-02-20 18:19 aleidinger * libmp3lame/takehiro.c: - CPU_features is now a struct 2001-02-20 18:19 aleidinger * libmp3lame/lame.c: - CPU_features is now a struct, no need to waste space for those bolean values (Frank) - introduce some KLEMM_44 protected code 2001-02-20 18:18 aleidinger * libmp3lame/util.c: - fixes + docu for ATHformula_Frank() (Frank) - don't compile old resampling in KLEMM_44 case 2001-02-20 18:17 aleidinger * libmp3lame/version.c: - doxygen parseable documentation - better lclint flags - enable get_lame_version_numerical() 2001-02-20 18:17 aleidinger * include/lame.h: - delete prototype of already removed get_lame_about() - add get_lame_version_numerical() and lame_version_t (now dshow didn't needs to include version.h to get the numerical version of lame (dshow not changed, I let pgubanov do this)) - introduce some KLEMM_44 protected code (Frank) - rework formatting and documentation to be more (IMO much more) readable (no lines longer than 80 chars, consistent formatting, looks alot cleaner) 2001-02-20 10:41 aleidinger * DEFINES: Remove KLEMM_04, there was a previous commit which handled it, see ChangeLog. 2001-02-20 01:56 markt * DEFINES, frontend/brhist.c, frontend/get_audio.c, frontend/timestatus.c: KLEMM 5,6,7 made the default & removed 2001-02-20 00:40 markt * libmp3lame/lame.c: simplified lame_encoder_buffer_interleaved: it now always calls lame_encoder_buffer() 2001-02-20 00:30 markt * libmp3lame/: encoder.c, lame.c, util.c, util.h: fix for --scale problem? made a new routine: fill_buffer() This is the generic routine used to copy data from the input buffer into lame's internal buffer, 'mfbuf[]'. It also calls the resample code if necessary, and the user selected rescaling code if necessary. 2001-02-20 00:26 markt * frontend/parse.c: added comment to vbr warning message 2001-02-20 00:24 markt * frontend/parse.c: re-added the warning about VBR modes. It seems to have been deleted at some point. This is because this website: http://www.kuro5hin.org/?op=displaystory;sid=2001/1/25/164540/759 is comparing Vorbis with lame -V4. While many people like the high bitrate VBR modes, lame -V4 is *often* of lower quality than CBR. 2001-02-19 18:29 aleidinger * test/VBR.op: - remove "--silent", lametest.py now handles this Aproved by: robert 2001-02-19 18:28 aleidinger * test/lametest.py: - allow relative paths in a more portable manner - should be more OS independand now - more file checks (readable/executable) - internally adds new option "--quiet" to the options This works on my system, it also should work on systems where the previous version worked. It's not as portable as it could be, search for XXX in the source. 2001-02-18 21:18 robert * frontend/main.c, frontend/parse.c, libmp3lame/lame.c, libmp3lame/version.h, test/VBR.op: new options --silent and --quiet to be really quiet new option --verbose (default) to turn -S/--silent off again --vbr-mtrh and --vbr-new use now ATH type 2 for VBR modes it is allowed to use different block types in stereo mode (not yet joint stereo) bumped version to 3.88 alpha 10 2001-02-18 12:11 aleidinger * dshow/: Makefile.am, Makefile.in: Add recently added files to the makefile. 2001-02-17 15:45 pgubanov * dshow/Encoder.cpp: gfp is sometimes zero in CEncoder::Encode() - why??? 2001-02-17 14:30 aleidinger * libmp3lame/: pcm.c, pcm.h: New code from Frank, some needed parts in different files aren't commited yet, they produce huge differences with lametest.py even if KLEMM_44 isn't defined. -> KLEMM_44 (new API + resampling) isn't usable yet 2001-02-17 14:27 aleidinger * test/lametest.py: - use "/usr/bin/env python" instead of "/usr/bin/python" in shebang line (portability) - use "-l" instead of "--lines" for wc (portability, has to run on every IEEE 1003.2 ("POSIX.2") compliant system) - bugfix, check for lame2 instead for lame1 in the lame2 part (Note: the entire test didn't work for me if I use e.g. ./lametest.py XXX.op ../../testcases/XXX ../../build.org/frontend/lame ...) 2001-02-17 14:17 pgubanov * dshow/: aboutprp.cpp, aboutprp.h: Elecard copyrigth added (executives need it for some reason) 2001-02-17 13:58 pgubanov * dshow/: Mpegac.cpp, Property.rc, UIDS.H, dshow.dsp, dshow.dsw, elogo.ico, resource.h: Some stability improvements + Elecard copyrigth added (executives need it for some reason) 2001-02-16 17:23 markt * doc/html/basic.html: added basic.html to cvs 2001-02-16 10:35 pgubanov * dshow/dshow.dsp: STDC_HEADERS defined in project settings 2001-02-16 10:33 pgubanov * libmp3lame/lame.c: mono handling in encode_buffer_interleaved caused access violation - fixed 2001-02-14 22:22 aleidinger * ChangeLog: Now we have a ChangeLog, generated from the output of "cvs log" 2001-02-14 22:21 aleidinger * ChangeLog.header: Header for the ChangeLog, not included at "make dist" 2001-02-14 22:20 aleidinger * TODO: remove Makefile.MSVC, robert seems to keep it up to date 2001-02-14 22:20 aleidinger * Makefile.B32: try to unbreak it, add configMS.h -> config.h (untested) 2001-02-14 22:20 aleidinger * DEFINES: add USE_FFT3DN 2001-02-14 22:19 aleidinger * INSTALL: * add some more info how to use some advanced features of our configure script * add some info for Cygwin users (use configure) * add some info about faster code with nasm 2001-02-14 20:50 robert * frontend/parse.c: added -V1 to Roel's --remix preset, I assume it was missing by accident 2001-02-14 16:38 aleidinger * Makefile.am.global, Makefile.in, aclocal.m4, configure, configure.in, Dll/Makefile.in, debian/Makefile.in, doc/Makefile.in, doc/html/Makefile.in, doc/man/Makefile.in, dshow/Makefile.in, frontend/Makefile.in, include/Makefile.in, libmp3lame/Makefile.in, libmp3lame/i386/Makefile.in, misc/Makefile.in, mpglib/Makefile.in: use new automake 1.4d (bugfixes) 2001-02-14 14:43 robert * libmp3lame/: encoder.c, util.h: tuning of the auto ath adjustment for --vbr-mtrh mode 2001-02-14 14:24 robert * libmp3lame/util.c: patch by Roel: tweaking his ATH modification (--athtype 3) 2001-02-13 18:27 markt * frontend/parse.c: fixed typo in parse.c 2001-02-13 18:24 markt * libmp3lame/psymodel.c: added a lot of documentation on the psycho acoustics to the top of psymodel.c 2001-02-13 18:22 markt * mpglib/: common.c, common.h, interface.c: improved head_check() function: When resyncing data stream, only look for headers of the same layer of the previous frames. i.e. dont allow layer 2 and layer 3 frames in the same stream. 2001-02-13 18:21 markt * frontend/: get_audio.c, parse.c: added the --r3mix option fixed bug with --decoder-mp3delay option added error message for non-8 and 16 bit input 2001-02-13 16:58 robert * frontend/parse.c, include/lame.h, libmp3lame/encoder.c, libmp3lame/lame.c, libmp3lame/psymodel.c, libmp3lame/quantize_pvt.c, libmp3lame/util.c, libmp3lame/util.h: first of all: this patch shows no difference in the CBR/ABR test - made athtype 3 default for VBR modes, 1 still default for CBR/ABR modes - made athadjust default for VBR modes, CBR/ABR modes don't need it - removed --athadjust switch, was only temporally solution - collected all spreaded ATH settings into ATH_t struct if someone needs a new ATH related variable, please add it here 2001-02-12 18:24 markt * doc/html/: contributors.html, history.html, index.html, node6.html, switchs.html: new html docs from Gabriel 2001-02-12 17:47 markt * test/lametest.py: print total pass/fail message at end 2001-02-09 16:47 robert * libmp3lame/quantize_pvt.c: patch by Gaby: allow ATH adjust for the ATH only modes too 2001-02-08 22:19 robert * test/VBR.op: update to the VBR python options file 2001-02-07 15:51 robert * libmp3lame/: encoder.c, vbrquantize.c: all patches --vbr-mtrh related encoder.c: - made a variant of Gaby's auto ATH adjust the default vbrquantize.c: - some small code moves - added some safety margin to the global gain 2001-02-06 21:43 robert * libmp3lame/: psymodel.c, vbrquantize.c: we should not try to hard to get high freqs thru' so I will let --vbr-mtrh as is. It seems to give reasonable file sizes again, even with Frank's ATH. 2001-02-05 10:18 robert * frontend/parse.c, include/lame.h, libmp3lame/encoder.c, libmp3lame/quantize_pvt.c: re-check-in of Gaby's ATH auto adjustment code. You need to specify --athadjust to get this SUBSTANTIALLY QUALITY IMPROVEMENT quote: "Also, we already have gfc->ath_lower (specified in db). No reason to add another variable which does the same thing, and does not even use the same units." That is not true, there is actually no gfc->ath_lower in dB. We have a gfp->ATHlower in dB. But this is of a totally different meaning. gfp->ATHlower will lower the ATH for the whole file by a fixed amount of x dB. gfc->ath_auto_adjust will lower the ATH on a frame by frame basis depending on the peak volume. 2001-02-05 04:58 markt * frontend/parse.c: Added warning about using VBR modes. This is because this website: http://www.kuro5hin.org/?op=displaystory;sid=2001/1/25/164540/759 is comparing Vorbis with lame -V4. While many people like the high bitrate VBR modes, lame -V4 is *often* of lower quality than CBR. 2001-02-05 02:36 shibatch * libmp3lame/psymodel.c: Reverted part of last tweaks of nspsytune. 2001-02-05 02:27 markt * HACKING: updated HACKING with directions on how to run the lametest.py python script 2001-02-05 02:24 markt * test/: CBRABR.op, VBR.op, lametest.py, nores.op: Adding a python script used for testing, along with some sample options files. 2001-02-05 02:23 markt * HACKING, libmp3lame/encoder.c, libmp3lame/quantize_pvt.c: reverted encoder.c and quantize_pvt.c back to 13:00 3 Feb 2001. These modifications broke my test cases. Any such changes need aproval first. Also, we already have gfc->ath_lower (specified in db). No reason to add another variable which does the same thing, and does not even use the same units. 2001-02-05 00:34 cisc * frontend/amiga_mpega.c: MPG_MD_LR_LR define was moved, set mode_ext to 0 instead (since we don't get that info anyway). 2001-02-04 23:56 robert * frontend/parse.c, libmp3lame/lame.c, libmp3lame/vbrquantize.c: parse.c: small change in default behaviour for --vbr-mtrh lame.c: it makes no sense for a sfb21 extra at sample frequencies below 44.1 kHz vbrquantize.c: oops, last commit was a merger from a wrong branch of mine 2001-02-04 23:28 shibatch * libmp3lame/quantize_pvt.c: Enabled auto-adjust ATH for nspsytune. 2001-02-04 23:14 shibatch * libmp3lame/psymodel.c: Tweaked nspsytune. 2001-02-03 23:20 robert * libmp3lame/: quantize_pvt.c, version.h: bumped version to alpha 9 some clean-up 2001-02-03 20:10 robert * libmp3lame/: encoder.c, quantize_pvt.c, util.c, util.h, vbrquantize.c: patch by Gabriel Bouvigne: auto adjust of ATH for low volume tracks a big improvement in quality! therefore on by default patch by Robert Hegemann: further improvement of --vbr-mtrh mode 2001-02-02 01:04 robert * libmp3lame/: quantize.c, quantize_pvt.c: --vbr-mtrh tweaks 2001-01-31 19:44 aleidinger * configure, configure.in: bugfix 2001-01-31 15:34 robert * libmp3lame/quantize.c: fix a typo I introduced by my last commit 2001-01-31 12:53 aleidinger * Makefile.am.global, Makefile.in, acconfig.h, acinclude.m4, aclocal.m4, config.h.in, configMS.h, configure, configure.in, depcomp, Dll/Makefile.in, debian/Makefile.in, doc/Makefile.in, doc/html/Makefile.in, doc/man/Makefile.in, dshow/Makefile.in, frontend/Makefile.in, include/Makefile.in, libmp3lame/Makefile.am, libmp3lame/Makefile.in, libmp3lame/i386/Makefile.in, misc/Makefile.in, mpglib/Makefile.in: - config*/Makefile*/ac*: * tests for *int*_t * test for 80 bit floats (for speed optimizations) * add pcm.* to the makefile * removed resample.[ch] from the makefile * depend upon automake 1.4b * fix in check for ccc (submitted by nold via the sourceforge patch page at the lame project page, patch id #103507) * something I may have forgotten Note: Please don't commit any Makefile.in if you didn't have changed the corresponding Makefile.am.

Added some windows code to rtp.c/mp3rtp.c: It is supposed to be much improved: LAME is really great project. However, RTP code for multicasting isn't very good.

I would like to please you to not include my name anywhere (there are several reason why, at the moment). However, code is very MSVC specific, so it is commented out with #if 0.

But: 1. MPEG2 encoding was broken 2. all my test cases failed. #11 is bad. #2 can be caused be general improvements, but coupled with #1 is a bad sign. I spent all of sunday tracking down the many changes, and trying to find what what the cause of what. I finally ran out of time and am going to revert some changes back to last working copy. Here is a summary: takehiro.c: newest version, except: count_bits_long uses old code (new code commented out). This code was breaking MPEG2 scfsi: uses old slen1_n, slen2_n. I will change this with the next commit.

LAME buffers input data until it has at least 1904 samples. It then starts processing them. The old MDCT routines processed 1728 samples and had a delay of 528. (introduced in 3.54) But the new MDCT routines, because the delay is so small (48 samples) actually need 2014 samples to be in the buffer! If you use the lame input routines, for MPEG1, this bug would not be found because the buffer always has well over 2014 samples in it. But it was possible to trigger it in MPEG2 encodings. It would also be possible to trigger this bug in programs that use lame_enc.dll and pass LAME data that is not in chunks of 1152 samples. 2000-05-19 17:23 markt * bitstream.c, lame.c, lame.h, parse.c, psymodel.c, testcase.mp3, vbrquantize.c: tweaks to psymodel initialization more work on vbrquantize.c 2000-05-19 01:38 markt * bitstream.c, gtkanal.c, l3side.h, lame.c, main.c, psymodel.c, quantize-pvt.c, takehiro.c, testcase.mp3, vbrquantize.c: more work on vbrquantize.c 2000-05-18 18:50 markt * main.c: updated decoder to remove initial delay 2000-05-18 05:38 markt * main.c, parse.c: lame --decode now outputs .wav files file length in header is set to 2^32-1, since we dont really know ahead of time how many samples are in the mp3 file. 2000-05-17 22:25 markt * quantize.c: ath lower bug in quantize.c fixed 2000-05-17 22:08 markt * quantize-pvt.c: calc_noise1 will compute noise (and related info) for last scalefactor band 2000-05-17 21:33 markt * quantize-pvt.c, takehiro.c: frame analyzer displays more data in scalefactor band 22 2000-05-17 19:50 markt * gtkanal.h, quantize-pvt.c, quantize-pvt.h, quantize.c, vbrquantize.c: modified frame analyzer to show last scalefactor band, energy and masking (from the ATH). distortion is not yet calculated in this band. 2000-05-17 18:08 markt * gtkanal.c, l3side.h, quantize-pvt.c, quantize.c, util.h: Possible fix for recent VBR/sweep bug: min bitrate not strictly enforced with -F, and analog silence was only being computed up th 16khz. 2000-05-17 17:16 markt * USAGE, brhist.c, get_audio.c, lame.c, lame.h, main.c, quantize.c, reservoir.c, util.c, util.h, vbrquantize.c: moved framenum, totalframes into lame.h (so programs which use libmp3lame can compute statis info.) 2000-05-15 14:34 takehiro * newmdct.c: more coding hack. 2000-05-14 23:38 cisc * newmdct.c: Changed M_PI to PI 2000-05-14 08:12 takehiro * newmdct.c: Naoki's short block mdct and more my coding hack for mdct 2000-05-14 05:51 takehiro * newmdct.c, util.h: mdct_long coding hack 2000-05-12 11:59 robert * util.h, lame.c, newmdct.c: code cleanup 2000-05-12 09:51 takehiro * newmdct.c, doc/html/history.html: more work in mdct_long and window_filtering 2000-05-12 05:03 markt * testcase.mp3: updated testcase.mp3 2000-05-12 05:02 markt * version.h: updated version to 3.83 alpha 2000-05-12 05:01 markt * API, README, version.h, doc/html/history.html: version 3.83 2000-05-10 13:55 takehiro * quantize-pvt.c: dirty hack for IEEE 754 FPU 2000-05-09 16:31 afaber * Dll/BladeMP3EncDLL.c: Fixed problem with build date string, temp string was not initialized properly (was missing a terminator character) 2000-05-09 11:30 takehiro * newmdct.c: Naoki's mdct_long with my coding hack. 2000-05-09 02:45 cisc * API, brhist.c: Added NOTERMCAP define and changed brhist.c accordingly. 2000-05-08 22:48 markt * testcase.mp3: [no log message] 2000-05-08 22:41 markt * quantize-pvt.c, doc/html/history.html: updated side channel 320kbs fix 2000-05-08 22:30 robert * Makefile, quantize-pvt.c: M/S reduce_side bug fixed, nonISO buffer mode should work now for 320 kbits MS streams too 2000-05-08 19:55 afaber * Dll/BladeMP3EncDLL.c: Bumped up version number of DLL version library, fixed some of the debugging code 2000-05-08 17:46 markt * doc/html/: contributors.html, examples.html, id3.html, index.html, lame.css, node5.html, node6.html, switchs.html: updated docs from Gaby 2000-05-08 17:40 markt * version.h: 3.82 alpha(CVS) version 2000-05-08 17:38 markt * version.h, doc/html/history.html: 3.81beta release 2000-05-08 17:31 markt * Makefile, USAGE, VbrTag.c, brhist.c, lame.h, parse.c, reservoir.c, util.c: removed ISO buffer limitation, added --strictly-enforce-ISO option 2000-05-08 00:06 markt * quantize-pvt.c, reservoir.c, vbrquantize.c: started work on vbrquantize.c 2000-05-07 11:09 robert * Makefile, Makefile.MSVC, lame.c, parse.c: -F option now working, updated Makefile for DOS 2000-05-07 03:59 takehiro * newmdct.c, util.h: new IDCT32 routine from Naoki and optimized by me. and more thread safe coding. 2000-05-06 22:20 markt * testcase.mp3: updated testcases 2000-05-06 22:20 markt * l3bitstream-pvt.h, lame.dsp, Dll/MP3EncDll.dsp: updated project files (for removal of ISO code) 2000-05-06 22:18 markt * Makefile, VbrTag.c, VbrTag.h, formatBitstream.c, formatBitstream.h, l3bitstream.c, l3bitstream.h, lame.c, quantize.c, util.c, util.h, vbrquantize.c: removed all ISO code 2000-05-06 22:09 markt * version.h: updated version to 3.81 alpha 1 (CVS version) 2000-05-06 22:07 markt * Makefile: updated makefile for beta release 2000-05-06 22:05 markt * version.h, doc/html/history.html: updated version for 3.80 beta release 2000-05-06 22:04 markt * USAGE, lame.c, lame.h, main.c, parse.c, quantize.c, vbrquantize.c: added -F option and compression ratio options 2000-05-06 19:16 markt * USAGE, lame.c, lame.h, parse.c, util.c: --freeformat option added.

[This is the first released version of the library GPL. It is numbered 2 because it goes with version 2 of the ordinary GPL.] 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 Library General Public License, applies to some specially designated Free Software Foundation software, and to any other libraries whose authors decide to use it. You can use it for your libraries, too. When we speak of free software, we are referring to freedom, 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 or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the 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 a program 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. Our method of protecting your rights has two steps: (1) copyright the library, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the library. Also, for each distributor's protection, we want to make certain that everyone understands that there is no warranty for this free library. If the library is modified by someone else and passed on, we want its recipients to know that what they have is not the original version, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that companies distributing free software will individually obtain patent licenses, thus in effect transforming the program into proprietary software. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License, which was designed for utility programs. This license, the GNU Library General Public License, applies to certain designated libraries. This license is quite different from the ordinary one; be sure to read it in full, and don't assume that anything in it is the same as in the ordinary license. The reason we have a separate public license for some libraries is that they blur the distinction we usually make between modifying or adding to a program and simply using it. Linking a program with a library, without changing the library, is in some sense simply using the library, and is analogous to running a utility program or application program. However, in a textual and legal sense, the linked executable is a combined work, a derivative of the original library, and the ordinary General Public License treats it as such. Because of this blurred distinction, using the ordinary General Public License for libraries did not effectively promote software sharing, because most developers did not use the libraries. We concluded that weaker conditions might promote sharing better. However, unrestricted linking of non-free programs would deprive the users of those programs of all benefit from the free status of the libraries themselves. This Library General Public License is intended to permit developers of non-free programs to use free libraries, while preserving your freedom as a user of such programs to change the free libraries that are incorporated in them. (We have not seen how to achieve this as regards changes in header files, but we have achieved it as regards changes in the actual functions of the Library.) The hope is that this will lead to faster development of free libraries. 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, while the latter only works together with the library. Note that it is possible for a library to be covered by the ordinary General Public License rather than by this special one. GNU LIBRARY GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Library 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 compile 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) 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. c) 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. d) 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 source code 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 to 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 Library 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 Library General Public License as published by the Free Software Foundation; either version 2 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 Library General Public License for more details. You should have received a copy of the GNU Library 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.

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, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). 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 at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' 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. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. 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. 4. Type `make install' to install the programs and any data files and documentation. 5. 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. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure 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 must use a version of `make' that supports the `VPATH' variable, such as 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 `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have 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. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' 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. 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'. Optional Features ================= 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. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM 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 host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. 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. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--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. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. lame-3.100/USAGE000644 001751 001751 00000112343 13144574734 014672 0ustar00netchildnetchild000000 000000 % lame [options] inputfile [outputfile] inputfile and/or outputfile can be "-", which means stdin/stdout. For more options, just type: % lame --help or lame --longhelp Note: The HTML documentation is more complete than this text file. ======================================================================= Constant Bitrate Examples: ======================================================================= fixed bit rate jstereo 128 kbps encoding: % lame -b128 sample.wav sample.mp3 Use highest quality mode, slowest: % lame -q0 -b128 sample.wav sample.mp3 Use fast encode, low quality (no noise shaping) % lame -f -b128 sample.wav sample.mp3 ======================================================================= Variable Bitrate Examples: ======================================================================= LAME has two types of variable bitrate: ABR and VBR. ABR is the type of variable bitrate encoding usually found in other MP3 encoders, Vorbis and AAC. The number of bits is determined by some metric (like perceptual entropy, or just the number of bits needed for a certain set of encoding tables), and it is not based on computing the actual encoding/quantization error. ABR should always give results equal or better than CBR: ABR: (--abr means encode with an average bitrate of around x kbps) % lame --abr 128 sample.wav sample.mp3 Another way to enable abr is: % lame --preset 128 sample.wav sample.mp3 VBR is a true variable bitrate mode which bases the number of bits for each frame on the measured quantization error relative to the estimated allowed masking. The value 0 is the highest quality, which creates bigger files, and the lowest is 9.999, which creates the smallest files. Decimal values can be specified, like: 4.51. The resulting filesizes depend on the input material. On typical music you can expect -V5 resulting in files averaging 132 kbps, -V2 averaging 200 kbps. Variable Bitrate (VBR): (use -V n to adjust quality/filesize) % lame -V2 sample.wav sample.mp3 ======================================================================= Low Bitrates ======================================================================= At lower bitrates, (like 24 kbps per channel), it is recommended that you use a 16 kHz sampling rate combined with lowpass filtering. LAME, as well as commercial encoders (FhG, Xing) will do this automatically. However, if you feel there is too much (or not enough) lowpass filtering, you may need to try different values of the lowpass cutoff and passband width (--resample, --lowpass and --lowpass-width options). ======================================================================= Streaming Example ======================================================================= % cat inputfile | lame [options] - - > output ======================================================================= Scripts are included (in the 'misc' subdirectory) to run lame on multiple files: bash script: mlame Run "mlame -?" for instructions. sh script: auenc Run auenc for instructions sh script: mugeco.sh Perl script which will re-encode mp3 files and preserve id3 tags: lameid3.pl Windows scripts: lame4dos.bat Lame.vbs (and an HTML frontend: LameGUI.html) ======================================================================= options guide: ======================================================================= These options are explained in detail below. By default, LAME accepts a PCM audio sample inside a .WAV container as the input file, in 8, 16, 24 and 32 bits integer and in IEEE FLOAT. If it is compiled with libsndfile, then it also supports the extra formats that the library supports. There is also support for raw PCM data and piped input Input options: --scale multiply PCM input by --scale-l scale channel 0 (left) input (multiply PCM data) by --scale-r scale channel 1 (right) input (multiply PCM data) by --gain number apply Gain adjustment in decibels, range -20.0 to +12.0. --swap-channel Swap Left and Right input channels --mp1input input file is an MPEG 1 Layer I file. decode on the fly --mp2input input file is an MPEG 1 Layer II file. decode on the fly --mp3input input file is an MPEG 1 Layer III file. decode on the fly --nogap <...> gapless encoding for a set of contiguous files --nogapout output dir for gapless encoding (must precede --nogap) --nogaptags allow the use of VBR tags in gapless encoding --out-dir path If no explicit output file is specified, a file will be written at given path. Ignored when using piped/streamed input Input options for raw PCM: -r read the input file as a raw (headerless) PCM stream -s n input sampling frequency in kHz (Default 44.1Khz) --signed input is signed (default) --unsigned input is unsigned --bitwidth w input bit width is w (default 16) -x swap bytes of input file --little-endian input is little-endian (default) --big-endian input is big-endian -a downmix stereo file to mono file for mono encoding. Needed with raw input for the -mm mode to do the downmix. Resampling and filtering: --lowpass Frequency(kHz), lowpass filter cutoff above freq. Range [0.001..50]kHz or [50..50000]Hz --lowpass-width Frequency(kHz), lowpass window width. Range [0.001..16]kHz or [16..50000]Hz (See further restriction in the detailed explanation) --highpass Frequency(kHz), highpass filter cutoff below freq. Range [0.001..16]kHz or [16..50000]Hz (See further restriction in the detailed explanation) --highpass-width Frequency(kHz), highpass window width (See further restriction in the detailed explanation) --resample n Sampling frequency of output file(kHz) Default=automatic depending on settings like bitrate. Operational: --preset type Enables some preconfigured settings.

Add id3 or dev to get help for a specified topic --usage Shows the common list of switches. Add id3 or dev to get help for a specified topic --longhelp Shows the complete list of switches ======================================================================= Detailed description of all options in alphabetical order ======================================================================= ======================================================================= Downmix ======================================================================= -a mix the stereo input file to mono and encode as mono. This option is only needed in the case of raw PCM stereo input (because LAME cannot determine the number of channels in the input file). To encode a stereo (RAW) PCM input file as mono, use "lame -m m -a" For WAV and AIFF input files, using "-m m" will always produce a mono .mp3 file from both mono and stereo input. ======================================================================= Average bitrate encoding (aka Safe VBR) ======================================================================= --abr n turns on encoding with a targeted average bitrate of n kbps, allowing to use frames of different sizes. The allowed range of n is 8...320 kbps, you can use any integer value within that range. ======================================================================= Use version 2 of the ID3 tag standard ======================================================================= --add-id3v2 Force addition of version 2 tag Tells LAME to add the tag information as id3v2. This implies adding both, a version 1 and a version 2 tag, if the values fit on a version 1 tag. See --id3v1-only and --id3v2-only if you want a more fine-grained control. ======================================================================= Bitrate ======================================================================= -b n MPEG-1 layer III sample frequencies (kHz): 32 48 44.1 bitrates (kbps): 32 40 48 56 64 80 96 112 128 160 192 224 256 320 MPEG-2 layer III sample frequencies (kHz): 16 24 22.05 bitrates (kbps): 8 16 24 32 40 48 56 64 80 96 112 128 144 160 MPEG-2.5 layer III sample frequencies (kHz): 8 12 11.025 bitrates (kbps): 8 16 24 32 40 48 56 64 The bitrate to be used. Default is 128kbps in MPEG1 (64 for mono), 64kbps in MPEG2 (32 for mono) and 32kbps in MPEG2.5 (16 for mono). When used with variable bitrate encodings (VBR), -b specifies the minimum bitrate to use. This is useful only if you need to circumvent a buggy hardware device with strange bitrate constrains. ======================================================================= Max bitrate ======================================================================= -B n see also option "-b" for allowed bitrates. Maximum allowed bitrate when using VBR/ABR. Using -B is NOT RECOMMENDED. A 128 kbps CBR bitstream, because of the bit reservoir, can actually have frames which use as many bits as a 320 kbps frame. ABR/VBR modes minimize the use of the bit reservoir, and thus need to allow 320 kbps frames to get the same flexability as CBR streams. This is useful only if you need to circumvent a buggy hardware device with strange bitrate constrains. ======================================================================= Endianess, big. ======================================================================= --big-endian Set the byte order to big-endian. This switch tells LAME that the RAW pcm input is encoded in big-endian instead of little-endian. ======================================================================= Sample bit with ======================================================================= --bitwidth Sets the bitwidth value With RAW pcm input, this switch lets you specify the bitwidth of the same (8 bits, 16 bits...) ======================================================================= Copyright ======================================================================= -c flag the encoded file as copyrighted ======================================================================= Clipping detection ======================================================================= --clipdetect Enable --replaygain-accurate and print a message whether clipping occurs and how far in dB the waveform is from full scale. This option is not usable if the MP3 decoder was _explicitly_ disabled in the build of LAME. See also: --replaygain-accurate ======================================================================= MPEG audio decode capability ======================================================================= --decode This uses LAME's HIP decoder to decode an MP3 file (layers 1, 2 and 3) to a wav file. If -t is used (disable wav header), LAME will output raw pcm in native endian format (use -x to swap bytes). This option is not usable if the MP3 decoder was _explicitly_ disabled in the build of LAME. HIP stands for Hip Isn't a Player and is based off of Michael Hipp's mpglib 0.2a ======================================================================= MPEG audio decode capability ======================================================================= --decode-mp3delay x Indicate a different encoder delay for decoding When decoding an mp3 file, LAME automatically corrects for the start delay that the encoder had to put into it. This setting lets you specify a different delay than LAME's own one, so that it is possible to compensate for the delay of mp3's generated with other encoders. ======================================================================= De-emphasis ======================================================================= -e n/5/c n = (none, default) 5 = 0/15 microseconds c = CCITT j.17 All this does is set a flag in the bitstream. If you have a PCM input file where one of the above types of (obsolete) emphasis has been applied, you can set this flag in LAME. Then the mp3 decoder should de-emphasize the output during playback, although most decoders ignore this flag. A better solution would be to apply the de-emphasis with a standalone utility before encoding, and then encode without -e. ======================================================================= Strictly enforce VBR minimum bitrate ======================================================================= -F strictly enforce VBR minimum bitrate. Without this option, passages of analog silence will be encoded at the minimum bitrate possible (32 or 8, depending on MPEG version). ======================================================================= Free format bitstreams ======================================================================= --freeformat LAME will produce a fixed bitrate, free format bitstream. User must specify the desired bitrate in kbps, which can be any integer between 8 and 640. Not supported by most decoders. Complient decoders (of which there are few) are only required to support up to 320 kbps. Decoders known to handle free format: supports up to mpg123 640 kbps MAD 640 kbps "lame --decode" 640 kbps l3dec 310 kbps ======================================================================= Gain ======================================================================= --gain Apply gain in decibels. Apply Gain adjustment in decibels, range -20.0 to +12.0. 0dBFS means no amplification. ======================================================================= High pass filter ======================================================================= --highpass number Use a highpass filter when encoding Enables a highpass filter of the specified frequency when encoding the source. Range [0.001..50]kHz or [50..50000]Hz. This is usually not required, and the gains are usually minimal. May be useful to remove an interference signal on 50Hz or 60Hz, or a DC offset. (default: disabled) Note: The current implementation has a minimum highpass frequency of (67.5/62)% of the sample rate (I.e. 481Hz at 44Khz). ======================================================================= High pass filter ======================================================================= --highpass-width width Set the width of the decaying curve. Specify the width in Hz of the decaying curve of the highpass. Range [16..50000]Hz The minimum (and default) width is 75% of a band's width (which is 1/64th of the sample rate). Note: See the remark in the --highpass command above. ======================================================================= ID3 tag modes ======================================================================= --id3v1-only Disable the use of id3v2. Put it before any tag setting. This setting tells LAME to use ID3 v1 tag only, and not create an ID3v2 even if it thinks it should. --id3v2-only Disable the user ov id3v1. Put it before any tag setting. This setting tells LAME to use ID3 v2 tag only. An ID3 v1 tag would not be written. --ignore-tag-errors Ignore tag information errors Put it before any tag setting. This tells lame to ignore the tag information it sees as erroneous and continue encoding without those. Without this setting, errors are reported and encoding does not start. ======================================================================= Endianess. little ======================================================================= --little-endian Set the byte order to little-endian. This switch tells LAME that the RAW pcm input is encoded in little-endian. It is the default setting. ======================================================================= Low pass filter ======================================================================= --lowpass number Use a lowpass filter when encoding Enables a lowpass filter of the specified frequency when encoding the source. Range [0.001..50]kHz or [50..50000]Hz Using a lowpass filter helps reducing the amount of data to encode. This is important in MP3 due to a limitation in very high frequencies (>16Khz). The default value depends on the target bitrate/quality. It is not recommended to change it as a general basis. --lowpass-width width Set the width of the decaying curve. Specify the width in Hz of the decaying curve of the lowpass. Range [0.001..16]kHz or [16..50000]Hz The lowpass is in the center of this curve. The minimum (and default) width is 75% of a band's width (which is 1/64th of the sample rate). ======================================================================= Modes: ======================================================================= -m m mono -m l get only the left channel of a stereo signal for a mono output -m r get only the right channel of a stereo signal for a mono output -m s (forced) L/R stereo -m j joint stereo -m f forced mid/side stereo -m d dual (independent) channels. Its purpose was meant for dual language streams where only one of them should be decoded. Most decoders just decode them as a stereo stream. -m a Currently, a synonym of m j. (In older releases it selected different modes depending on the bitrate) MONO is the default mode for mono input files. If "-m m" is specified for a stereo input file, the two channels will be averaged into a mono signal. (Note: See comments about the -a switch for RAW PCM streams) (FORCED) L/R STEREO encodes the left and the right signals independently, and gives more or less bits to each, depending on the currently available. JOINT STEREO is the default mode of encoding. jstereo means the encoder can use (on a frame by frame basis) either L/R stereo or mid/side stereo. In mid/side stereo, the mid(L+R) and side(L-R) channels are encoded, and more bits are allocated to the mid channel than the side channel. When there isn't too much stereo separation, this effectively increases the bandwidth, so having higher quality with the same amount of bits. Using mid/side stereo inappropriately can result in audible compression artifacts. Too much switching between mid/side and L/R stereo can also sound bad. To determine when to switch to mid/side stereo, LAME uses a much more sophisticated algorithm than that described in the ISO documentation. FORCED MID/SIDE STEREO forces all frames to be encoded mid/side stereo. It should only be used if you are sure every frame of the input file has very little stereo seperation. DUAL CHANNEL mode is similar to encode the left and right as two mono signals. Its purpose was meant for Dual language streams where only one of them should be decoded. Most decoders just decode them as a stereo stream INTENSITY STEREO Not supported. ======================================================================= MP3 input file ======================================================================= --mp1input --mp2input --mp3input MPEG layer I, II or III input file Assume the input file is a MP1/2/3 file. LAME will decode the input file before re-encoding it. Since MP3 is a lossy format, this is not recommended in general. But it is useful for creating low bitrate mp3s from high bitrate mp3s. If the filename ends in ".mp3" LAME will assume it is an MP3. For stdin or MP3 files which dont end in .mp3 you need to use this switch. ======================================================================= No Gap (continuous audio) encoding of multiple files ======================================================================= --nogap file1 file2 [...] Encodes multiple continuous files. Encodes multiple files (ordered by position) which are meant to be played gaplessly. By default, LAME will encode the files with accurate length, but the first and last frame may contain a few erroneous samples for signals that don't fade-in/out (as is the case of continuous playback). This setting solves that by using the samples from the next/previous file to compute the encoding. --nogapout dir Specify a directory for the output of the files encoded with --nogap This setting should precede --nogap, and is used to specify the alternate directory where to store the encoded files. The default one is the input file directory. --nogaptags Enables the use of VBR tags with files encoded with --nogap Tells LAME to put VBR tags to encoded files if they are encoded in VBR or ABR modes. Else, using the --nogap option doesn't generate it. ======================================================================= Disable historgram display ======================================================================= --nohist By default, LAME will display a bitrate histogram while producing VBR mp3 files. This will disable that feature. ======================================================================= Disable ReplayGain analysis ======================================================================= --noreplaygain By default ReplayGain analysis is enabled. This switch disables it. See also: --replaygain-accurate, --replaygain-fast ======================================================================= Non-original ======================================================================= -o mark the encoded file as a copy ======================================================================= CRC error protection ======================================================================= -p Turn on CRC error protection. It will add a cyclic redundancy check (CRC) code in each frame, allowing to detect transmission errors that could occur on the MP3 stream. However, it takes 16 bits per frame that would otherwise be used for encoding, and therefore will slightly reduce the sound quality. ======================================================================= ID3 V2 padding ======================================================================= --pad-id3v2 Pad ID3v2 tag. Pads the ID3v2 tag with extra 128bytes to allow it to expand. ======================================================================= Preset system. ======================================================================= --preset x Enable one of the presets Setting Meaning --preset medium -V 5 --preset standard -V 2 --preset extreme -V 0 --preset insane -b 320 --preset fast xxx In versions older than LAME 3.98, "fast" was needed to enable the vbr-new routine. It is no longer needed. --preset number --abr number --preset cbr number -b number Old compatibility settings. Meaningless --preset phone -b 16 -m m --preset phon+ / lw / mw-eu -b 24 -m m --preset mw-us -b 40 -m m --preset voice -b 56 -m m --preset fm / radio -b 112 --preset hifi -b 160 --preset cd -b 192 --preset studio -b 256 ======================================================================= Windows and OS/2 process priority control ======================================================================= --priority <type> (Windows and OS/2 only) Sets the process priority for LAME while running under Windows or IBM OS/2. This can be very useful to avoid the system becoming slow and/or unresponsive. By setting LAME to run in a lower priority, you leave more time for the system to update basic processing (drawing windows, polling keyboard/mouse, etc). The impact in LAME's performance is minimal if you use priority 0 to 2. The valid parameters are: 0 = Low priority (IDLE, delta = 0) 1 = Medium priority (IDLE, delta = +31) 2 = Regular priority (REGULAR, delta = -31) 3 = High priority (REGULAR, delta = 0) 4 = Maximum priority (REGULAR, delta = +31) Note that if you call '--priority' without a parameter, priority 0 will be assumed. ======================================================================= Algorithm quality selection ======================================================================= -q n Bitrate is of course the main influence on quality. The higher the bitrate, the higher the quality. But for a given bitrate, we have a choice of algorithms to determine the best scalefactors and Huffman coding (noise shaping). For CBR, ABR and --vbr-old modes, the following table applies -q 0 Use the best algorithms (Best Huffman coding search, full outer loop, and the highest precision of several parameters). -q 1 to -q 4 Similar to -q 0 without the full outer loop and decreasing precision of parameters the further from q0. -q 3 is the default -q 5 and -q 6 Same as -q 7, but enables noise shaping and increases subblock gain -q 7 to -q 9 Same as -f. Very fast, OK quality. Psychoacoustics are used for pre-echo and mid/side stereo, but no noise-shaping is done. For the default VBR mode since LAME 3.98, the following table applies -q 0 to -q 4 include all features of the other modes and additionally use the best search when applying Huffman coding. -q 5 and -q 6 include all features of -q7, calculate and consider actual quantisation noise, and additionally enable subblock gain. -q 7 to -q 9 This level uses a psymodel but does not calculate quantisation noise when encoding: it takes a quick guess. ======================================================================= Input file is raw pcm ======================================================================= -r Assume the input file is raw pcm. Sampling rate and mono/stereo/jstereo must be specified on the command line. Without -r, LAME will perform several fseek()'s on the input file looking for WAV and AIFF headers. Not supported if LAME is compiled to use LIBSNDFILE. ======================================================================= Slightly more accurate ReplayGain analysis and finding the peak sample ======================================================================= --replaygain-accurate Compute "Radio" ReplayGain on the decoded data stream. Find the peak sample by decoding on the fly the encoded data stream and store it in the file. ReplayGain analysis does _not_ affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from http://www.replaygain.org/ By default, LAME performs ReplayGain analysis on the input data (after the user-specified volume scaling). This behaviour might give slightly inaccurate results because the data on the output of a lossy compression/decompression sequence differs from the initial input data. When --replaygain-accurate is specified the mp3 stream gets decoded on the fly and the analysis is performed on the decoded data stream. Although theoretically this method gives more accurate results, it has several disadvantages: * tests have shown that the difference between the ReplayGain values computed on the input data and decoded data is usually no greater than 0.5dB, although the minimum volume difference the human ear can perceive is about 1.0dB * decoding on the fly significantly slows down the encoding process The apparent advantage is that: * with --replaygain-accurate the peak sample is determined and stored in the file. The knowledge of the peak sample can be useful to decoders (players) to prevent a negative effect called 'clipping' that introduces distortion into sound. Only the "Radio" ReplayGain value is computed. It is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1. This option is not usable if the MP3 decoder was _explicitly_ disabled in the build of LAME. (Note: if LAME is compiled without the MP3 decoder, ReplayGain analysis is performed on the input data after user-specified volume scaling). See also: --replaygain-fast, --noreplaygain, --clipdetect ======================================================================= Fast ReplayGain analysis ======================================================================= --replaygain-fast Compute "Radio" ReplayGain of the input data stream after user-specified volume scaling and/or resampling. ReplayGain analysis does _not_ affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from http://www.replaygain.org/ Only the "Radio" ReplayGain value is computed. It is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1. This switch is enabled by default. See also: --replaygain-accurate, --noreplaygain ======================================================================= Output sampling frequency in kHz ======================================================================= --resample n where n = 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48. The values as Hz instead of Khz are also supported. Else, the value will be ignored. Output sampling frequency. Resample the input if necessary. If not specified, LAME may sometimes resample automatically when faced with extreme compression conditions (like encoding a 44.1 kHz input file at 32 kbps). To disable this automatic resampling, you have to use --resamle to set the output samplerate equal to the input samplerate. In that case, LAME will not perform any extra computations. ======================================================================= Sampling frequency in kHz (for input RAW PCM) ======================================================================= -s n where n = sampling rate in kHz. Required for raw PCM input files. Otherwise it will be determined from the header information in the input file. LAME will automatically resample the input file to one of the supported MP3 samplerates if necessary. ======================================================================= Silent operation ======================================================================= -S don't print progress report ======================================================================= Scale ======================================================================= --scale <arg> Scales input by <arg>. This just multiplies the PCM data (after it has been converted to floating point) by <arg>. <arg> > 1: increase volume <arg> = 1: no effect <arg> < 1: reduce volume Use with care, since most MP3 decoders will truncate data which decodes to values greater than 32768. ======================================================================= Strict ISO complience ======================================================================= --strictly-enforce-ISO With this option, LAME will enforce the 7680 bit limitation on total frame size. This results in many wasted bits for high bitrate encodings. ======================================================================= Disable VBR tag/WAV header ======================================================================= -t This setting has two different uses: When encoding to VBR, this setting disables writing the VBR Tag (also known as XING tag). This tag is embedded by default in the frame 0 of MP3 file. It allows VBR aware players to accurately seek and compute playing times in such files. When decoding MP3 to WAV using --decode, this flag will disable writing the WAV header. The output will be raw pcm, native endian format. Use -x to swap bytes. ======================================================================= VBR quality setting ======================================================================= -V n Enable VBR encoding Encodes using the VBR algorithm, at the indicated quality. 0=highest quality, bigger files. 9.999=lowest quality, smaller files. Decimal values can be specified, like: 4.51 On average, the resulting bitrates are as follows: Setting Average bitrate (kbps) 0 245 2 190 3 175 4 165 5 130 Using -V 7 or higher (lower quality) is not recommended. ABR usually produces better results. ======================================================================= Swap bytes ======================================================================= -x swap bytes in the input file (and output file when using --decode). For sorting out little endian/big endian type problems. If your encodings sound like static, try this first. ======================================================================= Ignore scalefactor band 21 ======================================================================= -Y Ignore noise in sbf21, like CBR mode does Allows -V2, -V1 and -V0 to not encode the highest frequencies accurately, if doing so causes disproportional increases in bitrate. This is the same that CBR and ABR modes do. Due to the design of the MP3 format, to keep precision in the last scalefactor band, an encoder needs to increase the precision in all the bands (not only in this one). The consequence is an increase of bitrate (+60kbps in some cases) compared to not keeping that precision. Generally, this band should allow for distortions, so using this switch shouldn't cause harm. ���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/mpglib/����������������������������������������������������������������������������������000755 �001751 �001751 �00000000000 13170221264 015333� 5����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/dshow/�����������������������������������������������������������������������������������000755 �001751 �001751 �00000000000 13170221265 015206� 5����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/config.guess�����������������������������������������������������������������������������000755 �001751 �001751 �00000124431 13126231407 016407� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������#! /bin/sh # Attempt to guess a canonical system name. # Copyright 1992-2015 Free Software Foundation, Inc. timestamp='2015-03-04' # This file is free software; you can redistribute it and/or modify it # under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 3 of the License, or # (at your option) any later version. # # This program 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.

The library also contains routines for adding id3 tags and mp3 decoding. These routines are not fully documented, but you can figure them out by looking at "include/lame.h" and the example frontend encoder/decoder source code in frontend/main.c All of these steps should be done for every MP3 to be encoded. ========================================================================= 1. (optional) Get the version number of the encoder, if you are interested. void get_lame_version(char *strbuf, size_t buflen, const char *prefix); 2. Error messages. By default, LAME will write error messages to stderr using vfprintf(). For GUI applications, this is often a problem and you need to set your own error message handlers: lame_set_errorf(gfp,error_handler_function); lame_set_debugf(gfp,error_handler_function); lame_set_msgf(gfp,error_handler_function); See lame.h for details. 3. Initialize the encoder. sets default for all encoder parameters. #include "lame.h" lame_global_flags *gfp; gfp = lame_init(); The default (if you set nothing) is a J-Stereo, 44.1khz 128kbps CBR mp3 file at quality 5. Override various default settings as necessary, for example: lame_set_num_channels(gfp,2); lame_set_in_samplerate(gfp,44100); lame_set_brate(gfp,128); lame_set_mode(gfp,1); lame_set_quality(gfp,2); /* 2=high 5 = medium 7=low */ See lame.h for the complete list of options. Note that there are some lame_set_*() calls not documented in lame.h. These functions are experimental and for testing only. They may be removed in the future. 4. Set more internal configuration based on data provided above, as well as checking for problems. Check that ret_code >= 0. ret_code = lame_init_params(gfp); 5. Encode some data. input pcm data, output (maybe) mp3 frames. This routine handles all buffering, resampling and filtering for you. The required mp3buffer_size can be computed from num_samples, samplerate and encoding rate, but here is a worst case estimate: mp3buffer_size (in bytes) = 1.25*num_samples + 7200. num_samples = the number of PCM samples in each channel. It is not the sum of the number of samples in the L and R channels. The return code = number of bytes output in mp3buffer. This can be 0. If it is <0, an error occured. int lame_encode_buffer(lame_global_flags *gfp, short int leftpcm[], short int rightpcm[], int num_samples,char *mp3buffer,int mp3buffer_size); There are also routines for various types of input (float, long, interleaved, etc). See lame.h for details. 6. lame_encode_flush will flush the buffers and may return a final few mp3 frames. mp3buffer should be at least 7200 bytes. return code = number of bytes output to mp3buffer. This can be 0. int lame_encode_flush(lame_global_flags *,char *mp3buffer, int mp3buffer_size); 7. Write the Xing VBR/INFO tag to mp3 file. void lame_mp3_tags_fid(lame_global_flags *,FILE* fid); This adds a valid mp3 frame which contains information about the bitstream some players may find usefull. It is used for CBR,ABR and VBR. The routine will attempt to rewind the output stream to the beginning. If this is not possible, (for example, you are encoding to stdout) you should specifically disable the tag by calling lame_set_bWriteVbrTag(gfp,0) in step 3 above, and call lame_mp3_tags_fid() with fid=NULL. If the rewind fails and the tag was not disabled, the first mp3 frame in the bitstream will be all 0's. 8. free the internal data structures. void lame_close(lame_global_flags *); �����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/ltmain.sh��������������������������������������������������������������������������������000644 �001751 �001751 �00001170771 13122306670 015721� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������#! /bin/sh ## DO NOT EDIT - This file generated from ./build-aux/ltmain.in ## by inline-source v2014-01-03.01 # libtool (GNU libtool) 2.4.6 # Provide generalized library-building support services. # Written by Gordon Matzigkeit <gord@gnu.ai.mit.edu>, 1996 # Copyright (C) 1996-2015 Free Software Foundation, Inc. # This is free software; see the source for copying conditions.

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'.

For debugging, development, and studing MP3 frames produced by any encoder. lame_enc.dll a Windows DLL used by many GUIs which support lame. (Can only be compiled by MSVC???) lame.acm *** DEPRECATED *** a Windows ACM codec which can be used by many windows programs, and any directshow program. See MSVC project files in ACM directory. Right click on lame.inf to install. lame_enc.dshow a Windows direct show filter for lame. Potentially has more flexability than the ACM codec, but code needs some work. See MSVC project files in dshow directory libmp3lame.a the static encoding library used by all platforms, required by all the above targets. libmp3lame.so shared version of libmp3lame.a for *NIX platforms The following compile time options can be used. For libmp3lame.a and lame_enc.dll, none are required. On non-unix systems, these options must be set in config.h or in the IDE. On unix systems, they are set via ./configure. #define HAVE_MPGLIB compile in mpglib's mp3 *decoding* capibility #define HAVE_VORBIS compile in Vorbis decoding capibility (you need libvorbis already built) #define NOANALYSIS do not compile in hooks used by the MP3 frame analyzer. Options for the command line encoder: #define LIBSNDFILE to use Erik de Castro Lopo's libsndfile for input. ======================================================================= Building the software on *NIX platforms using configure: ======================================================================= Run the following commands: % ./configure % make % make install For a complete list of options, try "./configure --help" Some of the more usefull options: For the encoding library: --enable-mp3x Build the mp3 frame analyzer, 'mp3x' --enable-mp3rtp Build the encode-to-RTP program, 'mp3rtp' (broken as of August 2001) For the LAME front end encoder: --with-fileio=lame Use lame's internal file io routines [default] =sndfile Use Erik de Castro Lopo's libsndfile (Supports many more input formats, but no stdin possible currently) --with-sndfile-prefix=DIR Alternate location for libsndfile (if --with-fileio=sndfile) Other usefull configure options: --enable-debug Build a debug version --enable-expopt Enable some more optimizations flags for the compiler, may or may not produce faster code --prefix = PATH default is /usr/local (LAME currently installs: /usr/local/bin/lame /usr/local/lib/libmp3lame.a /usr/local/lib/libmp3lame.so /usr/local/include/lame.h --with-vorbis Enable Ogg Vorbis decoding support --with-vorbis-prefix = PATH specify where to find Vorbis libs Some more advanced ways to influence the build procedure (experienced users only, use it at your own risk): - If you want to use some custom defines for building (e.g. some out of the file "DEFINES") use: * bourne shell or compatible (ash, bash, zsh, ...): CONFIG_DEFS="-Dmy_define" ./configure * C shell or compatible (csh, tcsh, ...): setenv CONFIG_DEFS "-Dmy_define" ./configure - If you want to use some additional options for the compiler: * bourne shell or compatible (ash, bash, zsh, ...): CFLAGS="--my_flag" ./configure * C shell or compatible (csh, tcsh, ...): setenv CFLAGS "--my_flag" ./configure Or some combination of the above. Note: If configure detects the presents of "nasm" some additional speed improvements get compiled in (additional assembler code to detect and use multimedia extensions of the used processor). ======================================================================= Building the software on *NIX platforms without configure: ======================================================================= % make -f Makefile.unix ======================================================================= Building the software on Windows with MSVC: (or MSVC + 3rd party C compiler such as ICL) ======================================================================= There are MSVC project files, and a Makefile.MSVC included with the project. For production use, be sure to compile a "Release" target, with the "maximum speed" compile option, and #define NDEBUG. It is possible to compile the GTK frame analyzer under windows, see README.WINGTK Various build options can be set in configMS.h Note: project files for building lame.exe seem to be broken or not quite compatable with MSVC6. The most reliable way to build lame and lame_enc.dll is to run the .bat script (comes with MSVC6) which sets up your VC environment to work from the command line, and then: copy configMS.h config.h nmake -f Makefile.MSVC comp=msvc asm=no Project files for the dll, ACM codec and directshow filter seem to be in better sahpe. ======================================================================= Building the software on Windows with free compilers: ======================================================================= LAME can be compiled with various Windows ports (all free) of GCC (DJGPP, Mingw32). See README.DJGPP. For Mingw32, you should now be able to use the Unix Makefile that comes with LAME. Try: "make -f Makefile.unix UNAME=MSDOS" You may need to remove these lines from brhist.c: #ifdef _WIN32 COORD Pos; HANDLE CH; CONSOLE_SCREEN_BUFFER_INFO CSBI; #endif Mingw32 users may also try to use the unix configure script (explained above), it has _untested_ support for Mingw32. Cygwin users should use the unix configure script (explained above). If you have problems with the configure script try: CC=gcc ./configure Patches to enable the build of the lame_enc.dll with Cygwin and autoconf / automake / libtool are welcome! To use the Borland C compiler (now free!) see README.B32 and Makefile.B32. Borland can also compile the lame_enc.dll, but this is untested. Can DJGPP or Mingw32 produce lame_enc.dll?

Update by Albert Faber (Sept 07 2000), changed instructions to compile with latest glib/gtk libraries. Update by Albert Faber (Oct 20 2000), small adaptions to be conform the new lame directory structure. Update by Gabriel Bouvigne (Jan 07 2004), changes to be conform to the VC6 worspace structure. Update by Gabriel Bouvigne (Nov 11 2006), changes to be conform to the VC8 worspace structure. Tested with gtk+-dev-1.3.0-20030115 and glib-dev-2.12.4 =========================================================================== How to compile the MP3 frame analyzer (MP3x): =========================================================================== You first need to get hold of the latest GTK and GLIB include files and lib files. You can download them freely from the WINGTK project WEB site. (see http://www.gtk.org, and click on the WINGTK link.) Download: glib-dev-VERSION.zip, gtk+-dev-VERSION.zip and extralibs-dev-VERSION.zip where VERSION indicates the release data, so it will look something like 20000805 unzip all three zip files in a WinGTK subdirectory, which is created from the lame analyzer directory (for example, D:\CVS\lame\WinGtk) You will end up with the following directory tree D:\CVS\lame\analyzer\WinGtk\src\glib D:\CVS\lame\analyzer\WinGtk\src\gtk+\glib D:\CVS\lame\analyzer\WinGtk\src\gtk+ Set Mp3x as your current active project, recompile everything, and you're done. =========================================================================== How to run and use the MP3 Frame analyzer =========================================================================== To run MP3x.exe, you need the GTK DLL files: Either instal them on your system, or put them in the same directory mp3x.exe resides. Example: mp3x.exe myfile myfile can be a mp3 file, or a wav file. === End of Document === ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/STYLEGUIDE�������������������������������������������������������������������������������000644 �001751 �001751 �00000015535 07200060007 015464� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������* The LAME API is frozen. Poorly designed as it is, don't change it, and add to it sparingly. * Don't take it upon yourself to go through LAME with the sole purpose of updating everything to match this guide. Especially important: don't change the spacing, indentation, curly braces, etc, in routines you did not write. * If you want to make a change which effects many many functions, please check with the maintainer first. * Respect the indentation of the author of the original function. If the indentation is not consistent, use 4. * Don't use tabulators (the character with the value '\t') in source code, especially these with a width of unequal 8. Lame sources are using different sizes for tabulators. * Don't set the macro NDEBUG in alpha versons. NDEBUG should be set for beta versions. * check important assumptions with an assert() * use int for all integer quantities. LAME requires 32 bit ints, so you can assume int is at least 32 bits. Don't use 'long'. Don't use 'unsigned' unless ABSOLUTELY necessary. Don't use 'char' just to save bytes. If 64 bits is required, use int64. Annnotation: ISO C calls the 64 bit int type not int64 but int64_t. * Avoid using float or double, and instead use: (defined in machine.h). FLOAT for variables which require at least 32bits FLOAT8 for variables which require at least 64bits On some machines, 64bit will be faster than 32bit. Also, some math routines require 64bit float, so setting FLOAT=float will result in a lot of conversions. Annotation (pfk): The new ISO C standard passed in autumn 1999 has defined new types for exactly this reason. There are called float_least32_t and float_least64_t and have at least the advantage that you not need to explain their meaning. Annotation (mt): we will adopt this convention in Jan 1, 2003. * The internal representation of PCM samples in type 'sample_t', currently this is a FLOAT. * Use SI base units. Lame mixes Hz, kHz, kbps, bps. This is mess. Example: float wavelength_green = 555.e-9; unsigned data_rate = 128000; float lowpass_freq = 12500.; Converting between user input and internal representation should be done near the user interface, not in the most inner loop of an utility function. ---------------------------------------------------------------------------------- Edited version of the Linux Kernel Style Guide: ---------------------------------------------------------------------------------- Chapter 1: Indentation Respect the indentation of the author of the original function. If the indentation is not consistent, don't change it. If you are so anal-retentive about these things and you can't bare to even look at code with poor indentation, change it to 4. Chapter 2: Placing Braces The other issue that always comes up in C styling is the placement of braces. Unlike the indent size, there are few technical reasons to choose one placement strategy over the other, but the preferred way, as shown to us by the prophets Kernighan and Ritchie, is to put the opening brace last on the line, and put the closing brace first, thusly: if (x is true) { we do y } However, there is one special case, namely functions: they have the opening brace at the beginning of the next line, thus: int function(int x) { body of function } Heretic people all over the world have claimed that this inconsistency is ... well ... inconsistent, but all right-thinking people know that (a) K&R are _right_ and (b) K&R are right. Besides, functions are special anyway (you can't nest them in C). Note that the closing brace is empty on a line of its own, _except_ in the cases where it is followed by a continuation of the same statement, ie a "while" in a do-statement or an "else" in an if-statement, like this: do { body of do-loop } while (condition); and if (x == y) { .. } else if (x > y) { ... } else { .... } Rationale: K&R. Also, note that this brace-placement also minimizes the number of empty (or almost empty) lines, without any loss of readability. Thus, as the supply of new-lines on your screen is not a renewable resource (think 25-line terminal screens here), you have more empty lines to put comments on. Chapter 3: Naming C is a Spartan language, and so should your naming be. Unlike Modula-2 and Pascal programmers, C programmers do not use cute names like ThisVariableIsATemporaryCounter. A C programmer would call that variable "tmp", which is much easier to write, and not the least more difficult to understand. HOWEVER, while mixed-case names are frowned upon, descriptive names for global variables are a must. To call a global function "foo" is a shooting offense. GLOBAL variables (to be used only if you _really_ need them) need to have descriptive names, as do global functions. If you have a function that counts the number of active users, you should call that "count_active_users()" or similar, you should _not_ call it "cntusr()". Encoding the type of a function into the name (so-called Hungarian notation) is brain damaged - the compiler knows the types anyway and can check those, and it only confuses the programmer. No wonder MicroSoft makes buggy programs. LOCAL variable names should be short, and to the point. If you have some random integer loop counter, it should probably be called "i". Calling it "loop_counter" is non-productive, if there is no chance of it being mis-understood. Similarly, "tmp" can be just about any type of variable that is used to hold a temporary value. Chapter 4: Functions Document functions. Keep functions as modular as possible. But don't adhere to artificial line number limitations. For example, lame_encode_frame() encodes a single MP3 frame and is a long sequence of function calls. It makes no sense to break this into two or more routines. Chapter 5: Commenting Comments are good, but there is also a danger of over-commenting. NEVER try to explain HOW your code works in a comment: it's much better to write the code so that the _working_ is obvious, and it's a waste of time to explain badly written code. Generally, you want your comments to tell WHAT your code does, not HOW. Also, try to avoid putting comments inside a function body: if the function is so complex that you need to separately comment parts of it, you should probably go back to chapter 4 for a while. You can make small comments to note or warn about something particularly clever (or ugly), but try to avoid excess. Instead, put the comments at the head of the function, telling people what it does, and possibly WHY it does it. �������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/lame.spec.in�����������������������������������������������������������������������������000644 �001751 �001751 �00000013240 10775731507 016276� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������%define name @PACKAGE@ %define ver @VERSION@ %define rel 1 %define prefix %{_usr} %define docdir %{_defaultdocdir} Summary : LAME Ain't an MP3 Encoder... but it's the best.

������������������������������������������������������������������������������������������������������������������������������������������������������������������������Can I use LAME in my commercial program? Yes, you can, under the restrictions of the LGPL (see COPYING in this folder). The easiest way to do this is to: 1. Link to LAME as separate library (libmp3lame.a on unix or lame_enc.dll or libmp3lame.dll on windows) 2. Fully acknowledge that you are using LAME, and give a link to our web site, www.mp3dev.org 3. If you make modifications to LAME, you *must* release these modifications back to the LAME project, under the LGPL. �������������������������lame-3.100/TODO�������������������������������������������������������������������������������������000644 �001751 �001751 �00000011054 13144574734 014570� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������1. bug in resample code: downsampling from 44101 to 44100 causes a seg fault. Workaround in place for now: resampling disabled if input/output samplerates agree to 4 digits. 2. high bitrate encodings have trouble on some hardware players. Track this down. Probably caused by --strictly-enforce-ISO and IXMAX_VAL. Try setting IXMAX_VAL back to 8191 and/or maxmp3buf=8*960 to see if there is a working combination. note: one of the decoder bugs was identified. It is caused by using different block sizes on both channels. A parameter need to be added to Lame to handle workarounds. 3 frontend: code is a complete mess. But it has so many debugged features it will be a lot of work to re-write. 4. MSVC project files. It would be nice to create a working MSVC6 workspace, which included all the projects as possible targets: lame.exe mp3x.exe (require GTK libs) lame_enc.dll ACM codec directshow codec I think the only MSVC5 project that we need to preserve is for lame_enc.dll, since Albert Faber (still?) doesn't use VC6? But no reason we cant have VC5 and VC6 project files for the dll. 5. NOGAP encoding: -nogap: more testing, fix options, test id3 tags? Can we change id3 tags without reseting the encoder?? At the end of encoding 1.wav, call lame_get_mf_samples_to_encode() to find the number of non encoded buffered PCM samples. Then encode samples from 2.wav until these PCM samples have been encoded, *THEN* call lame_encode_flush_nogap() and close out file 1.mp3. NOGAP decoding: lame --decode --nogap file1.mp3 file2.mp3 file3.mp3 should also work. What needs to be done: get_audio.c: We need a way to open a second mp3 file, without calling lame_decode_init() and reinitializing mpglib. And the mpglib needs to know to look for new Xing tags at the beginning of file2.mp3 and file3.mp3. 6. Does stdin work when LAME is compiled to use libsndfile? (new version of libsndfile will support this - try this out) 7. LAME has problems with pure DC input. i.e. a square wave with a frequency well below 20 Hz. Not very important, but it should be fixed. 8. mgplib has bugs with i-stereo. flag denoting invalid i-stereo value (= frame is m/s stereo) is not correct. 9. lowpass filter: for M/S stereo, use more filtering for the side channel, less filtering for mid channel. We need to first replace the polyphase filter with an FIR lowpass filter with finer frequency resolution before implementing this. 10. LAME has a 31 point FIR filter used for resampling, which can also be used as a lowpass. When resampling is done, use that filter to also lowpass instead of the polyphase filter. 11. Even when resampling is not needed, should we use an FIR filter for the lowpass? If it is not too much slower, yes. If it is slower, then it should be an option since it will produce higher quality. 12. We should consider moving the experts options from the *long help* text into an *experts only* help text. The average Joe gets knocked down by the huge number of possibilities to setup lame. 50. Better tonality estimation. Gpsycho uses predictability, and so needs a delay to detect the tonality of a sound. Nspsytune seems to miss tonals when several of them are too narrow. We would probably need the best of both. 60. Different ATH handling for sfb21. We are using the minimum value of ath in each whole sfb. in sfb21 this leads to very high bitrates. We could perhaps use 2 or 3 ath partitions in sfb21 note: partially done 70. Use mixed blocks. 90. Use intensity stereo. This is a must-have for low bitrates, but if the algorythm is very good it could also be used in every case. Note: mpg123 (and all derivatives, like xmms and lame/mpglib) have bugs in the intensity stereo decoding. Bugs have been there for years since there are very few intensity stereo mp3's out there. 95. Merge GOGO's fast assembler routines. 96. It would be nice to save some information whilst encoding a: wave -> mp3 a RIFF/wave can contain LIST chunks with information about author, title, etc. ==> could go into TAG fields of resulting mp3 b: mp3 -> mp3 ==> we could copy the TAG directly c: mp3 -> wave ==> copy TAG into LIST chunk 97. Integrate plusV extensions 99.

Lame-enc DLL
Interface version 1.32 (and above)
(Lame engine version: 3.93 or higher)
Programmers Manual

The lame_enc.dll and this manual is copyright by Albert L Faber
Originally the the DLL interface is modeled after the BladeEnc DLL interface
which is copyrighted by Tord Jansson and Jukka Poikolainen
This document and the DLL interface may be distributed freely
as long as modifications are released under the LGPL license.

Distribution

People and companies  who wants to distribute lame_enc.dll with their commercial products are free to do so as far as I'm concerned (LGPL license), but should be aware that lame_enc.dll might infringe certain MP3 related software patents held by Fraunhofer IIS in certain countries.


 

Disclaimer

lame_enc.dll and this manual is distributed 'as is' with no warranty of any kind. The Author is not to be held responsible for the result of any use or misuse of this product.
 
 

Current Bugs and Limitations

Although the interface is designed to be able to handle multiple parallel streams it can't be done yet due to limitations in the engine, only one stream is allowed.
 

Future Compatibility

This interface should be compatible with all future versions of lame_enc.DLL without any need to recompile your programs. You should therefore not check the version number upon start and prevent users from running your program with a later version of lame_enc.DLL.
 

How to use the DLL

1. Fill in a BE_CONFIG structure and send it to beInitStream(). Make sure that BE_ERR_SUCCESSFUL is returned.

2. Reserve at least the amount of memory returned in dwBufferSize as your output buffer.

3. Call beEncodeChunk() until you've encoded everything you want.

4. Call beDeinitStream() to make sure that all encoded data is flushed out before closing the stream.

5. Close the stream using beCloseStream()

6. Finally, call the beWriteVBRHeader() functions, to insert the INFO tag MP3 Header. This is an extension of the Xing VBR tag which is also used for CBR encodings. This call can only be omitted if the INFO tag was explicilty disabled in the BE_CONFIG Structure.

A handy feature is the available Lame_enc.dll debug option, which will dump the important lame internal settings to a text file.
 

 

Return Values

See the header-file for a complete list of function return values. All functions should return BE_ERR_SUCCESSFUL unless something went wrong.
 

Type definitions

The DLL is by default compiled with the MS Visual C/C++ compiler, which has the following type definitions:

Type Description
CHAR signed char (8 bits)
BYTE unsigned char (8 bits)
SHORT signed short (16 bits)
WORD unsigned short (16 bits)
INT signed long (32 bits)
LONG signed long (32 bits)
BOOL signed long (32 bits) (YES, 32 bits for a one bit value)
TRUE = 0
FALSE=-1
DWORD unsigned long (32 bits)
FLOAT floating point (32 bits)
DOUBLE float point (64 bits)
LPCSTR const char* (32 bits pointer to zero terminated character string)

Within the lame_enc.dll All the structure elements are one byte alligned (due to backwards compatibility with BladEnc.DLL!

 

The BE_CONFIG Structure

Currently there the BE_CONFIG structure has to varians, the old MP3 config structure that is truly compatible with the old BladeEnc interface, and the new defined LHV1 structure, which can set far more options in the lame encoder

 

The MP3 BE_CONFIG - structure (OBSOLETE)

This is the old structure as it was originally defined by the BladeEnc.DLL interface. However, I do highly recommend to use the new Lame specific config structure, since it gives you more control over the Lame encoder settings.

These are the members of the BE_CONFIG structure you need to fill in before you call beInitStream():
 

dwConfig Specifies what kind of output you want. Since only MP3 currently is supported you must set this to BE_CONFIG_MP3
format.mp3.dwSampleRate      Samplerate in Hz for MP3 file. This can be set to either 32000, 44100 or 48000.
format.mp3.byMode Stereomode for MP3 file. This can be either BE_MP3_MODE_STEREO, BE_MP3_MODE_DUALCHANNEL or BE_MP3_MODE_MONO.
format.mp3.bitrate Bitrate (i.e. size) of MP3 file in kBit/s. Allowed bitrates are: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320.
format.mp3.bCopyright If this is set to TRUE the Copyright bit in the MP3 stream will be set.
format.mp3.bCRC Set this to TRUE in order to enable CRC-checksum in the bitstream.
format.mp3.bOriginal If this is set to TRUE the Original bit in the MP3 stream will be set.
format.mp3.bPrivate If this is set to TRUE the Private bit in the MP3 stream will be set.

 

The LHV1 BE_CONFIG - structure (recommended)

These are the members of the LHV1 BE_CONFIG structure, you need to fill in before you call beInitStream():

dwConfig Specifies what kind of output you want. Since only MP3 currently is supported you must set this to BE_CONFIG_LAME
   
format.LHV1.dwStructVersion Indicates the version number of the structure, current version number is 1
format.LHV1.dwStructSize Specifies the size of the BE_CONFIG structure (currently 331 bytes)
   
format.LHV1.dwSampleRate  Samplerate in Hz for MP3 file. This can be set to either:
32000, 44100 or 48000 for MPEG-I
16000, 22050 or 24000 for MPEG-I
8000, 11025 or 12000 for MPEG-II.5
format.LHV1.dwReSampleRate Specifies to which sample rate the input stream has to be resampled, if set to 0, the encoder will decide which ReSample rate to use
format.LHV1.nMode Stereomode for MP3 file. This can be either BE_MP3_MODE_STEREO, BE_MP3_MODE_JSTEREO, BE_MP3_MODE_DUALCHANNEL or BE_MP3_MODE_MONO.
format.LHV1.dwBitrate For CBR, this specifies the actual bitrate, for VBR, it specifies the minimum bitrate
Allowed bitrates are: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320.for MPEG-I
Allowed bitrates are: 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144 and 160.for MPEG-II

Note: dwBitrate is used as the minimum bitrate in the case of using a VBR mode.
format.LHV1.dwMaxBitrate When VBR mode is enabled, it specifies the maximum allowed bitrate (see also dwBitrate to specify the minium bitrate), for CBR mode this setting is ignored.
format.LHV1.nPreset Keep in mind that the presets can overwrite some of the other settings, since it is called right before the encoder is initialized
The nPreset option can be set to one of the following presets values::

LQP_NOPRESET (don't use any presets)
LQP_NORMAL_QUALITY (quality is set to 5)
LQP_LOW_QUALITY (quality is set to 9)
LQP_HIGH_QUALITY (quality is set to 2)
LQP_VOICE_QUALITY (use for voice encoding)
LQP_R3MIX (r3mix preset option)
LQP_VERYHIGH_QUALITY (quality is set to 0)
LQP_STANDARD (lame command line alt-preset standard)
LQP_FAST_STANDARD (lame command line alt-preset fast standard)
LQP_EXTREME (lame command line alt-preset extreme)
LQP_FAST_EXTREME (lame command line alt-preset fast extreme)
LQP_INSANE (lame command line alt-preset insane)
LQP_ABR (lame command line alt-preset abr)
LQP_CBR(lame command line alt-preset cbr)

(old lame preset options)
LQP_PHONE
LQP_SW
LQP_AM
LQP_FM
LQP_VOICE
LQP_RADIO
LQP_TAPE
LQP_HIFI
LQP_CD
LQP_STUDIO
 
format.LHV1.bCopyright If this is set to TRUE the Copyright bit in the MP3 stream will be set.
format.LHV1.bCRC Set this to TRUE in order to enable CRC-checksum in the bitstream.
format.LHV1.bOriginal If this is set to TRUE the Original bit in the MP3 stream will be set.
format.LHV1.bPrivate If this is set to TRUE the Private bit in the MP3 stream will be set.
   
format.LHV1.nVbrMethod Sepecifes if the VBR method to use, currently the following settings are supported:

VBR_METHOD_NONE (don't use VBR, use CBR encoding instead),
VBR_METHOD_DEFAULT (default VBR method)
VBR_METHOD_OLD (old VBR method, proven to be reliable)
VBR_METHOD_NEW (new VBR method, faster than VBR_METHOD_OLD)
VBR_METHOD_MTRH (depreciated, same as VBR_METHOD_NEW)
VBR_METHOD_ABR (Average Bitrate Encoding, see also format.LHV1.dwVbrAbr_bps)
format.LHV1.bWriteVBRHeader Sepecifes if the a XING VBR header should be written or not. When this option is enabled, you have to call the beWriteVBRHeader function when encoding has been completed. Keep in mind that the VBR info tag can also be written for CBR encoded files, the TAG info can be useful for additional info like encoder delay and the like.
format.LHV1.bEnableVBR Specifies if VBR encoding option shall be used or not, possible values are TRUE/FALSE
format.LHV1.nVBRQuality Quality option if VBR is enabled (0=highest quality, 9 is lowest quality)
format.LHV1.dwVbrAbr_bps If the Average Bit Rate is specified, the lame encoder ignores the nVBRQuality settings (However, bEnableVBR must be set to TRUE and the format.LHV1.nVbrMethod parameter should be set to VBR_METHOD_ABR). The allowed range for the format.LHV1.dwVbrAbr_bps parameter any integer value between:

MPEG-I: 32000 .. 320000 bps
MPEG-II: 8000 .. 160000 bps
   
format.LHV1.bNoBitRes Disables the bit-resorvoir and disables the insertion of padded frames
format.LHV1.nQuality Quality Setting, HIGH BYTE should be NOT LOW byte, otherwhise quality is set to 5. This is done to be backward compatible. So to set quality to 3, you have to set the nQuality parameter to 0xFC03.
format.mp3.btReserved For future use, set all elements to zero

 

 

beInitStream()

Synopsis: BE_ERR beInitStream( PBE_CONFIG pbeConfig, PDWORD dwSamples, PDWORD dwBufferSize, PHBE_STREAM phbeStream )
Parameters:
pbeConfig Pointer at the struct containing encoder settings.
dwSamples Pointer at double word where number of samples to send to each beEncodeChunk() is returned.
dwBufferSize Pointer at double word where minimum size in bytes of output buffer is returned.
phbeStream Pointer at integer where Stream handle is returned.
Description: This function is the first to call before starting an encoding stream.

beEncodeChunk()

Synopsis: BE_ERR beEncodeChunk( HBE_STREAM hbeStream, DWORD nSamples, PSHORT pSamples, PBYTE pOutput, PDWORD pdwOutput )
Parameters:
hbeStream Handle of the stream.
nSamples Number of samples to be encoded for this call. This should be identical to what is returned by beInitStream(), unless you are encoding the last chunk, which might be smaller.
pSamples Pointer at the 16-bit signed samples to be encoded. These should be in stereo when encoding a stereo MP3 and mono when encoding a mono MP3.
pOutput Where to write the encoded data. This buffer should be at least of the minimum size returned by beInitStream().
pdwOutput Where to return number of bytes of encoded data written. The amount of data written might vary from chunk to chunk.
Description: Encodes a chunk of samples. Please note that if you have set the output to generate mono MP3 files you must feed beEncodeChunk() with mono samples!

beDeinitStream()

Synopsis: BE_ERR beDeinitStream( HBE_STREAM hbeStream, PBYTE pOutput, PDWORD pdwOutput )
Parameters:
hbeStream Handle of the stream.
pOutput Where to write the encoded data. This buffer should be at least of the minimum size returned by beInitStream().
pdwOutput Where to return number of bytes of encoded data written.
Description: This function should be called after encoding the last chunk in order to flush the encoder. It writes any encoded data that still might be left inside the encoder to the output buffer. This function should NOT be called unless you have encoded all of the chunks in your stream.

beCloseStream()

Synopsis: BE_ERR beCloseStream( HBE_STREAM hbeStream )
Parameters:
hbeStream Handle of the stream.
Description: Last function to be called when finished encoding a stream. Should unlike beDeinitStream() also be called if the encoding is canceled.

beVersion()

Synopsis: VOID beVersion( PBE_VERSION pbeVersion )
Parameters:
pbeVersion Pointer at struct where version number, release date and URL for homepage is returned.
Description: Returns information like version numbers (both of the DLL and encoding engine), release date and URL for lame_enc's homepage. All this information should be made available to the user of your product through a dialog box or something similar.

 

 

beWriteVBRHeader()

Synopsis: VOID beWriteVBRHeader( LPCSTR pszMP3FileName )
Parameters:
pszMP3FileName Const Pointer zero terminated string, that contains the MP3 file name.
Description: Writes a Xing Header in front of the MP3 file. Make sure that the MP3 file is closed, and the the beConfig.format.LHV1.bWriteVBRHeader has been set to TRUE. In addition, it is always save to call beWriteVBRHeader after the encoding has been finished, even when the beConfig.format.LHV1.bWriteVBRHeader is not set to TRUE

 

 

 

Lame_enc.dll debug option

The lame_enc.dll has a built-in debug option, that dumps all the important internal settings to a text file. To enable this feature, create a text file in the Windows directory which is named lame_enc.ini, and should contain the following two lines

[debug]
WriteLogFile=1

Save this text file, and each time you encode a file, the settings are added to a file name lame_enc.txt, that is located in the same directory as the lame_enc.dll

This DLL is compatible with the BladeEnc.dll. See BladeMP3EncDLL.c for details of the calling sequence, and BladeMP3EncDLL.h for details of the data that must be passed to the DLL. As of yet, there is no other documentation. To use this DLL as a replacement for BladeEnc.dll, you need to populate the 'mp3' struct. To use more advanced features of LAME, you need to populate the LHV1 struct instead. Delphi 4 Users: Gabriel Gélin has contributed a .PAS file, do you can access the DLL from Delphi.

Common and recommended switches

Common settings

% lame [options] inputfile [outputfile]
  • Constant Bitrate: -b number or --preset cbr number Valid values for the -b settings depend on the sampling rate1. 
    lame -b 128 sample.wav sample.mp3
  • Variable Bitrate (ABR mode): --abr number or --preset number Valid values for the --abr setting range from 8 to 320. 
    lame --abr 128 sample.wav sample.mp3
  • Variable Bitrate (VBR mode): -V number Valid values are from 0 to 9, with decimal values possible, where 0 is the highest quality while 9.999 is the lowest one. 
    lame -V2 sample.wav sample.mp3

Hydrogenaudio recommended settings

    Very high quality, HiFi, home, or quiet listening, with best file size : -V0 (avg. 245 kbps) or -V1 (avg. 225 kbps) or -V2 (avg. 190 kbps) or -V3 (avg. 175 kbps).

    VBR settings will normally produce transparent results. Audible differences between these presets may exist, but are rare.

  • Very high quality, HiFi, home, or quiet listening, with maximum file size2 : -b 320

    This CBR mode will maximize the MP3's bitrate and overall file size. The extra space may allow for some parts of the audio to be compressed with fewer sacrifices, but to date, no one has produced ABX test results demonstrating that perceived quality is ever better than the highest VBR profiles described above.

  • Portable, listening in noisy conditions, lower bitrate, smaller file size: -V4 (avg. 160 kbps) or -V5 (avg. 130 kbps) or -V6 (avg. 115 kbps)

    -V6 produces an "acceptable" quality, while -V4 should be close to perceptual transparency.

  • Very low bitrate, small sizes, eg. for voice, radio, mono encoding : --abr 80 (stereo) or --abr 56 -m m (mono)

    For very low bitrates, up to 100kbps, ABR is most often the best solution. --preset voice is only available in the command line front-end, and is there for compatibility. It is currently mapped to --abr 56 -mm, so that means that the recommendation would be to encode in mono, and use ABR.

  1. Codec sample frequencies (kHz) bitrates (kbps)

    MPEG-2.5 layer III 8, 11.025, 12 8 16 24 32 40 48 56 64
  2. Lossy codecs, like MP3, should not be used for archiving, since the nature of lossy encoding always changes the original sound, even if it sounds transparent. Use lossless codecs for this purpose.

LAME Official Logo

The LAME Project

LAME is a high quality MPEG Audio Layer III (MP3) encoder licensed under the LGPL.

It is developed as an educational tool to be used in learning about MP3 encoding. The goal of the LAME project is to use the open source model to improve the psycho acoustics, noise shaping and speed of MP3.

LAME is not for everyone - it is distributed as source code only and requires the ability to use a C compiler. However, many popular ripping and encoding programs include the LAME encoding engine, see: Software which uses LAME.

Using the LAME encoding engine (or other mp3 encoding technology) in your software may require a patent license in some countries.

Introduction to encoding

Introduction

There is a lot of confusion surrounding the terms audio compression 1, audio encoding, and audio decoding. This section will give you an overview what audio coding (another one of these terms...) is all about.

The purpose of audio compression

Up to the advent of audio compression, high-quality digital audio data took a lot of hard disk space to store. Let us go through a short example.

You want to sample 1 minute of your favourite song and store it on your harddisk. Because you want CD quality, you sample at 44.1 kHz, stereo, with 16 bits per sample.

44100 Hz means that you have 44100 values per second coming in from your sound card (or input file). Multiply that by two because you have two channels. Multiply by another factor of two because you have two bytes per value (that's what 16 bit means). The song will take up 44100 samples/s · 2 channels · 2 bytes/sample · 60 s/min ~ 10 MBytes of storage space on your harddisk.

In order to stream this over internet, a speed of at least 1.41Mbits/ s is needed, which wasn't a common speed at all at the time MP3 was invented. If you wanted to download that, given an average 56k modem connected at 44k, it would take 1.41Mbits · 1000 kbits/Mbit / 44 kbits ~ 32 times as much.
This means 32 minutes just to download one minute of music!

Digital audio coding, which - in this context - is synonymously called digital audio compression as well, is the art of minimizing storage space (or channel bandwidth) requirements for audio data. Modern perceptual audio coding techniques (like MPEG Layer III) exploit the properties of the human ear (the perception of sound) to achieve a size reduction by a factor of 11 with little or no perceptible loss of quality.

Therefore, such schemes are the key technology for high quality low bit-rate applications, like soundtracks for CD-ROM games, solid-state sound memories, Internet audio, digital audio broadcasting systems, and the like.

The two parts of audio compression

Audio compression really consists of two parts. The first part, called encoding, transforms the digital audio data that resides, say, in a WAVE file, into a highly compressed form called bitstream. To play the bitstream on your soundcard, you need the second part, called decoding. Decoding takes the bitstream and re-expands it to a WAVE file.

The program that effects the first part is called an audio encoder. LAME is such an encoder . The program that does the second part is called an audio decoder. Nowadays there are lots of players that decode MP3

Compression ratios, bitrate and quality

It has not been explicitly mentioned up to now: What you end up with after encoding and decoding is not the same sound file anymore: All superfluous information has been squeezed out, so to say. It is not the same file, but it will sound the same - more or less, depending on how much compression has been performed on it.

Generally speaking, the lower the compression ratio achieved, the better the sound quality will be in the end - and vice versa.
Table 1.1 gives you a rough estimate about the quality you can expect.

Because compression ratio is a somewhat unwieldy measure, experts use the term bitrate when speaking of the strength of compression. Bitrate denotes the average number of bits that one second of audio data will take up in your compressed bitstream. Usually the units used will be kbps, which is kbits/s, or 1000 bits/s (not 1024).
To calculate the number of bytes per second of audio data, simply divide the number of bits per second by eight.

table 1.1: bitrate versus sound quality
Bitrate Bandwidth Quality comparable to
16 kbps mono 5.5 khz above shortwave radio / telephone
32 kbps mono 8.5 khz near AM (medium wave) radio
64kbps mono, 128 kbps stereo 16 khz FM radio
-V 3~-V 0 (160~200 kbps)
(variable bitrate)		 18~20 khz perceptual transparency versus CD2
  1. Audio compression (also called coding) means reduce the size (bytes) that the original source requires to be stored. This is not the same than compressors in DSP (or audio effects). The latter reduces the dynamic range of the audio so that there is less difference in perceived loudness between its strong and subtle parts.
  2. Lossy encoding (as opposed to lossless) cannot guarantee transparency all of the time. This is the value accepted as the sweet spot.

MP3 encoder mailing list

For general discussions and comments about LAME and MP3 encoding, you can check the MP3 encoder mailing list. Keep in mind this is not the preferred list if you want to get in touch with the developers.

Archives are also available (older archives: before October 2000)

LAME development mailing list

The lame-dev list is right place for everything related to LAME development: bug reports, questions and suggestions concerning the encoder, the documentation and the web pages. It's also the best way to get in touch with the active developers. Archives are provided by SourceForge.

CVS mailing list

If you want to be automatically notified of commits to CVS, you can subscribe to the lame-cvs list.

IRC

Some developers and other interested parties can eventually be found on the #mp3encoder channel on the FreeNode Network.

Bug reports/tracker

To submit bug reports, you can use the bug tracker besides the lame-dev mailing list. Please be descriptive in your bug report. You should clearly mention your problem, LAME version used and how to reproduce the bug.

Contact developers

Here is the list of developers. If you encounter a problem, please use any of the ways mentioned above instead of directly contact a developer.

LAME Official Logo

LAME - Mid/Side Stereo

During years, what is called Joint-stereo has been misunderstood.
Joint stereo in MP3 is a mechanism to selectively choose between three modes of storing stereo information. These three modes are Simple Stereo , Mid-Side Stereo, and Intensity-Stereo.

In Simple Stereo, the encoder analyzes the left and the right channels independently and stores the information as-is, without further checking the similarities in the signal1

In Mid-Side Stereo, the encoder analyzes the left, right2 , mid (l+r) and side (l-r) channels. It then gives more bits to the mid than the side channel (as usually the side channel is less complex) and then stores just the mid and side channels into the resulting MP3.
This way, the mid channel can be encoded as if the frame was bigger, and as such have more quality with the same bitrate.
Note: Mid/side in MP3 is switched frame-by-frame. In AAC, it can be switched band by band.

Intensity-Stereo (not supported in LAME) uses a technique known as joint frequency encoding, which is based on the principle of sound localization.
Human hearing is predominantly less acute at perceiving the direction of certain audio frequencies. By exploiting this 'limitation', intensity stereo coding can reduce the data rate of an audio stream with little or no perceived change in apparent quality.
It works by merging the upper spectrum into just one channel (thus reducing overall differences between channels) and transmiting a little side information about how to pan certain frequency regions.
This type of coding does not perfectly reconstruct the original audio because of the loss of information and can cause unwanted artifacts. However, for very low bitrates this tool usually provides a gain of perceived quality. 3

The LAME mid/side switching criterion, and mid/side masking thresholds are taken from Johnston and Ferreira, Sum-Difference Stereo Transform Coding, Proc. IEEE ICASSP (1992) p 569-571.

The MPEG AAC standard claims to use mid/side encoding based on this paper.

  1. This is not the same than dual-mono. Dual-mono should be used where the left and right channels of the input file contain two different streams, where you should choose one (as in two different languages)
  2. If one channel has much less noise masking in a certain band than the other, it could happen than the noise spread (by mid/side stereo) may no longer be masked for that channel. If both channels have the same masking, then the noise spread between both channels will be equally well masked.
    To prevent this from happening, there is an analysis done on the left and right channel to determine the noise masking thresholds and properly mask the noise.
  3. Quote from wikipedia Joint_stereo.

LAME 3.98.4    March 22 2010

  • Joseph Flynn
    • Improvements for LAME DirectShow filter:
      • Added support for the DirectShow IAMStreamConfig Interface to the LAME encoder filter output pin.
      • Modified the DirectShow filter registration section so that the LAME Encoder filter is correctly registered in the Audio Compressors filter category. This will allow third-party encoding applications using the DirectShow System Device Enumerator Interface to correctly detect the LAME encoder when querying the Audio Compressors filter group.
      • Modified the filter registration information so that the MP3 audio subtype is correctly reported as being supported on the encoder output pin. This will allow third-party encoding applications using the DirectShow IFilterMapper2 Interface to recognize that the LAME encoder supports MP3 output.
      • Altered the Filter Merit Value that was being used when the filter was registered so that it is now using the standard DirectShow compressor filter merit value of MERIT_DO_NOT_USE (0x200000). Previously, the filter was being registered using a value of MERIT_SW_COMPRESSOR (0x100000), which was at a lower priority (i.e. worse priority) than MERIT_DO_NOT_USE. This prevented the LAME Encoder filter from being selected for use by some third-party encoding applications.
      • Added code to calculate the frame length of the audio frames used for the nBlockSize element of the WAVEFORMATEX output structure. Previously this value was simply hard-coded to 1.
  • Robert Hegemann
    • Fix for Bugtracker item [ 2973877 ] A problem regarding the new drain code

LAME 3.98.3    February 27 2010

  • Rogério Brito:
    • Update the debian packaging for the new release.
  • Robert Hegemann
    • The ignore-tag-errors switch had no effect when embedding album art, fixed.
    • Library API change: lame_decode functions are now obsolete but still present, please use hip_decode instead. The reason for this change is: lame_decode functions use a single global variable within the library to store decoder setup, hip_decode functions don't. The encoder now uses hip_decode internally and it is now possible to use clipdetect feature while reencoding mp3 to mp3.
    • Workaround for FFMPEG bug, which uses to call lame_encode_flush more than once in a loop.
    • Windows: program icon and version info added (when building with VC9)
    • Fix for Bugtracker item [ 2688413 ] lib name problem in Microsoft Visual Studio 6
    • Fix for Bugtracker items [ 2051870, 2423650, 2928684 ] several small documentation issues
    • Fix for Bugtracker item [ 2723518 ] resampling in 3.98 and 3.99alpha
    • Fix for Bugtracker item [ 2891879 ] Because of Windows API change, there was a problem with the prority switch.
    • Fix for Bugtracker item [ 2893101 ] Access Violation in BladeMP3EncDLL if UNICODE was defined.
    • Fix for Bugtracker item [ 2887359 ] Wrong length in ID3v2 tag when num_samples isn't set
    • Fix for Bugtracker item [ 2872590 ] LameTAG: "Music length" missmatch in LAME 3.98
    • Fix for Bugtracker item [ 2824296 ] wrong enc_padding value in LAME 3.99a and 3.98.3 (from CVS)
    • Revisiting the FhG decoder problem (FhG V1.5 build 50, ships with MS Windows): enabling the new-drain-code seems to solve that issue better, than restricting the buffer size (see below: 3.98 beta 1, May 16 2007).
    • Patch submitted by Bernhard Doebler, tracker item [ 2807676 ] Error when building Lame with NASM support
    • Patch submitted by Mancuso Raffaele, tracker item [ 2406420 ] compile lame_enc.dll under cygwin

    • Fix for Bugtracker item [ 2039648 ] potential memory leak in parse_args() function in parse.c
    • Fix for some tagging issues:
      • Made search for ID3v1 genres more sloppy, abbrevations may match more often as some simple typos. Examples:
        • --tg "Alt. Rock" matches genre "Alternate Rock"
        • --tg "acapela" matches genre "A Cappella"
      • New switch --pad-id3v2-size "n": adds ID3v2 tag with n padding bytes.

LAME 3.98    July 4 2008

  • Anton Sergunov:
    • Frontend DirectShow: enabling LAME dshow filter to connect to "File Writer Filter".
  • Rogério Brito:
    • Updates to the Debian Packaging
    • Fixes to the abx tool for Unix systems (so that more people can evaluate LAME's compression against the original files)
  • Alexander Leidinger:
    • explicitely link the math lib to the lame lib
    • add switch to disable the use of the compaq optimized math lib

LAME 3.98 beta 8   April 13 2008

  • Robert Hegemann:
    • LAME now accepts a floating point value in the range [0,...,10[ as VBR quality setting, like -V5.678
    • Found and fixed some suspicious code in additive masking calculation for VBR-NEW
    • bug-fix:experimental code was defaulted by accident for VBR-NEW
    • fix for some endianess problem on big-endian machines

LAME 3.98 beta 7   April 6 2008

  • Robert Hegemann:
    • libmp3lame API: allow frontends to separately retrieve LAME/Xing and ID3 data, because the old library automatism makes it impossible to make fully buffered encodes.
    • libmp3lame API: added some experimental unicode ID3 tagging code.
    • frontends: write itself final ID3 tags and LAME/Xing header frame
    • lame_enc.dll: writes itself final LAME/Xing header frame
    • Latest changes to the new VBR psymodel:
      • uses a different spreading function
      • bug-fix for out-of-bounds array access (program stack corruption possible)

LAME 3.98 beta 6   December 16 2007

  • Robert Hegemann:
    • Feature request [ 1811483 ] WAVE_FORMAT_EXTENSIBLE support (PCM)
    • Fix for some rare scalefactor selection issue the newer vbr code had at low compression levels
    • Fix for Bugtracker item[ 1813496 ] AIFF parsing bug
    • Latest changes to the new VBR code:
      • it now has its own psy model, a derivation from NSPSY.
      • some more tuning has been done for this new psy model. Many thanks to Horst Albrecht and Myles Thaiss.
      • the "out-of-bits" strategy is reworked
    • It was possible, that the "interchannel masking effects feature" was used by the dual-channel-mode for bi-lingual encodings too. It was meant to work on stereo L/R channels only.

LAME 3.98 beta 5   August 12 2007

  • Jonathan Stott:
    • Bug tracker items: [ 1590693 ] ID3v2 tag not writing, [ 1636267 ] ID3v2 tags overwritten
      If the output file is opened 'write-only', then LAME can't update the LAME tag. In this case LAME silently overwrote the first bytes of the file and an optional ID3v2 tag disappeared. Now an error message will be printed and no data is written in this case.
  • Robert Hegemann:
    • Fix for Bugtracker item [ 1719593 ] Track numbers > 255 not allowed even with --id3v2-only
    • Fix for Bugtracker item [ 1742623 ] fail(lame --mp3input -m m -b 128 --resample 8 *.mp3 **.mp3)
      The problem here was, the input files are MPEG-1 Layer2 files named as MP3s. Even if you leave out the --mp3input switch LAME tried to decode the input files as Layer3 files because of the file name extension and because it found some valid looking Layer3 synchronization header. The fixed LAME version does not assume the file name extension is always correct and treats the files depending on the first found MPEG sync word. The files in question are now correctly detected as Layer2 files and transcoding does succeed.
    • Fix for Bugtracker item [ 1445175 ] Input being stdin fails in Windows on WAV files
      The problem here was, seeking on pipes shows some different behaviour depending on C-Library implementations. The workaround tries to detect it's working on a pipe and doing some reading instead of seeking in that case.
    • Fixing some memory leak in the 'lame_enc.dll'.
    • Fix for Bugtracker items [ 1160757, 1160741 ] --little-endian / --big-endian not working
      These switches where originally intended to be used together with Libsndfile only.
    • Fix for Bugtracker item [ 1746336 ] Incorrect Bitrate with ABR und --resample, LAME 3.98b4
      Some earlier bug-fix had some typo. As a result, when adding a '--resample 123' switch, the average bitrate rised upto maximum bitrate.

    • Out of bits strategy for the newer VBR code overhauled
    • LAME API: the ID3 tag functions do not store the pointers passed anymore, they do make deep copies of strings passed as parameters.
    • Changes in LAME frontend switches regarding ID3 tags:
      --tg "MyGenre" will route unknown ID3v1 genres to "Other" for ID3v1 tags and will be stored as plain text "MyGenre" for ID3v2 tags. Genres given by known ID3v1 numbers will be stored as its corresponding text in ID3v2 tags.
      --tn "02/02" will store the track number specified as plain text as-is for ID3v2 tags.

  • Robert Hegemann:  some short block bug fixes
  • Robert Hegemann:  Big improvements to --vbr-mtrh, now encodes much more frequencies over 16khz
  • Robert Hegemann:  --vbr-new code disabled (outdated and lower quality) and replaced with --vbr-mtrh (Both --vbr-new and --vbr-mtrh now default to mtrh)
  • Robert Hegemann:  reordering of --longhelp to give more information, --extrahelp dropped
  • Darin Morrison:  Totally revamped and extremely high quality unified preset system and other general quality improvements now available with --alt-presets:
    • some improvements to psychoacoustics (vast improvements over default L.A.M.E. modes) when --alt-preset is used including:
      • Improved tuning of short block usage.
      • Improved quantization selection usage (the -X modes), now adapts between appropriate modes on the fly. Also helps on "dropout" problems and with pre-echo cases.
      • Improved joint stereo usage. Thresholds are better tuned now and fix some "dropout" problems L.A.M.E. suffers from on clips like serioustrouble.
      • Improved noise shaping usage. Now switches between noise shaping modes on the fly (toggles -Z on and off when appropriate) which allows lower bitrates but without the quality compromise.
      • Clips vastly improved over default L.A.M.E. modes (vbr/cbr/abr, including --r3mix): castanets, florida_seq, death2, fatboy, spahm, gbtinc, ravebase, short, florida_seq, hihat, bassdrum, 2nd_vent_clip, serioustrouble, bloodline, and others. No degraded clips known.
      • VBR bitrates are now more "stable" with less fluctuation -- not dipping too low on some music and not increasing too high unnecessarily on other music. "--alt-preset standard" provides bitrates roughly within the range of 180-220kbps, often averaging close to 192kbps.
    • --alt-presets replace the --dm-presets and "metal" preset is removed and replaced with generic abr and cbr presets.
    • --alt-preset extreme (note the 'e') replaces xtreme to help eliminate some confusion
    • --alt-preset vbr modes now have a fast option which offers almost no compromise in speed.
    • --alt-preset standard (and "fast standard") are now much lower in bitrate, matching --r3mix with an overall average, though offering higher quality especially on difficult test samples.
    • --alt-presets are no longer just "presets" as in a collection of switches, instead they are now quality "modes" because of special code level tunings (those mentioned above).
    • Use --alt-preset help for more information.
  • Roel VdB: more tuning on the --r3mix preset
  • Jon Dee, Roel VdB:  INFO tag
  • Alexander Leidinger, mp3gain@hotmail.com:  added --scale-l and --scale-r to scale stereo channels independantly
  • Takehiro Tominaga:  new noise shaping mode, offering more "cutting edge" shaping according to masking, enabled via -q0
  • Mark Taylor:  More work on --nogap
  • Gabriel Bouvigne:  Small changes to abr code for more accurate final bitrate
  • Gabriel Bouvigne, mp3gain@hotmail.com:  Preliminary ReplayGain analysis code added (not functional yet)
  • Gabriel Bouvigne, Alexander Leidinger:  Documentation updates
  • John Dahlstrom, DSPguru@math.com:  floating point interface function in the Windows DLL

  • Mark Taylor:  (optional) Vorbis support, both encoding and decoding.  LAME can now produce .ogg files, or even re-encode your entire .ogg collection into mp3.   (Just kidding: it is always a bad idea to convert from one lossy format to another)
  • ?: Bug fixed causing VBR to crash under windows.   (pretab[] array overflow)
  • Sergey Sapelin: Another bug found in the mpg123 MPEG2 tables.  Now fixed for the mpg123 based decoder in LAME.

LAME 3.83beta  May 19  2000

  • Mark Taylor:  Bug in buffering routines:  in some cases, could cause MDCT  to read past end of buffer.  Rare in MPEG2, even more rare for MPEG1, but potentially serious!
  • Mark Taylor:  MDCT/polyphase filterbank was not being "primed" properly.  Does not effect output unless you set the encoder delay lower than the default of 576 samples.
  • Mark Taylor:  "vdbj" and "Caster"  found several VBR bugs (now fixed):   1.  Analog silence detection only checked frequencies up to 16 kHz.  2.  VBR mode could still somehow avoid -F mode.  3.  VBR mode would ignore noise above 16 kHz (scalefactor band 22), Now calc_noise1 will compute the noise in this band when in VBR mode.  Not calculated in CBR  mode since CBR algorithm has no way of using this information.
  • Mark Taylor:  scalefactor band 22 info (masking(=ATH),  noise and energy) now displayed in frame analyzer.
  • VBR code ATH tuning was disabled by accident in 3.81, now fixed.

  • Scott  Manley and Mark Taylor:  good resampling routine finaly in LAME.  uses a 19 point FIR filter with Blackman window.  Very slow for non integer resampling ratios.
  • Iwasa Kazmi:  fixed SIGBUS error:  VBR and id3 tags were using data after it was free()'d.
  • Robert Hegemann:  Improved VBR tuning.  #define RH_QUALITY_CONTROL and #RH_SIDE_VBR now the defaults.

  • Mark Taylor:  free format bitstreams can be created with --freeformat, and specify any integer bitrate from 8 to 320kbs with -b.
  • Mark Taylor: lame be used as a decoder (output raw pcm only):  lame --decode input.mp3 output.pcm

  • "LAME 3.69beta" becomes LAME 3.70 "stable"

LAME 3.69beta   April 6 2000

  • "spahm":  default mode selection bug fixed.  In some cases, lame was defaulting to regular stereo instead of jstereo when the user did not specify a mode.

LAME 3.68beta  April 4 2000

  • Mark Taylor: mono encoding bug in DLL fixed.
  • Ingo Saitz: bug in --cwlimit argument parsing fixed.
  • Scott Manly: bug in 4-point resample code fixed.

LAME 3.67beta  March 27 2000

  • Robert Hegemann:  jstereo now enabled for MPEG2 encodings
  • Mark Taylor: old M/S stereo mode which used L/R maskings has been removed.
  • Mark Taylor: Xing MPEG2 VBR headers now working.
  • Mark Taylor:  When quantized coefficients are all 0 in a band, set scalefactors to 0 also to save a few bits.
  • Ingo Saitz:  Problems with framesize calculation when using -f fast-math option fixed.

LAME 3.66beta March 21 2000

  • Bug fixes in BladeEnc DLL, possible click in last mp3 frame, VBR historgram display, byteswapping option, ASM quantize routines work for both float and double.

LAME 3.65beta   March 17 2000

  • Enabled ASM version of quantize_xrpow() - accidently disabled in lame3.64.

LAME 3.64beta  March 16 2000

  • Don Melton:  id3v1.1 tags & id3 bugfixes
  • Gabriel Bouvigne:  L/R matching block type fix
  • Bug fixed which was allowing quantized values to exceed the maximum when not using -h
  • Mark Taylor: Fitlers based on polyphase filterbank.  should be slightly better since the responce is independent of the blocktype, and they are slightly faster.
  • Mark Taylor: API:  the API changed slightly - and this should be the final version. There is a new routine: lame_encode_buffer() which takes an arbritray sized input buffer, resamples & filters if necessary, encodes, and returns the mp3buffer.  There are also several new #defines, so it is possible to compile a simple encoding library with no decoding or file I/O or command line parsing.  see the file API for details.
  • Mark Taylor: MSVC stuff:  lame.exe (with and without the frame analyzer) and the CDex lame_enc.dll should compile under MSVC.  The MSVC5 project files may need some tweaking.  In particular, you need to make sure LAMEPARSE, LAMESNDFILE and HAVEMPGLIB are defined.  (and HAVEGTK for the GTK stuff).

LAME 3.63beta  February 20  2000

  • Robert Hegemann:  FPE with -h fixed?
  • Mathey Hendry:  FPE error catching for Cygwin, FPE fix for vbr mode and output to /dev/null
  • Jeremy Hall:  Fixed problems with input files where the number of samples is not known.
  • Mathew Hendry:  ASM quantize_xrpow() for GNU i386

  • Ingo Saitz:  --help option added, with output to stdout
  • Alfred Weyers: short block AAC spreading function bug fixed
  • Takehiro Tominaga:  new scalefac data structure - improves performance!
  • Lionel Bonnet:  Bug fixed in MPEG2 scalefactor routine: scalefactors were being severly limited.

  • Sigbjørn Skjæret, Takehiro Tominaga:  faster pow() code.
  • Joachim Kuebart:  Found some unitialized variables that were effecting quality for encodings which did not use the -h option (now fixed).
  • Mark Taylor: More modularization work.   It is now possible to use LAME as a library where you can set the encoding parameters directly and do your own file i/o.   The calling program is now it's own mp3 output.  For an example of the LAME API, see main.c, or mp3rtp.c or mp3x.c.  These can all be compiled as stand alone programs which link with libmp3lame.a.
  • Felix vos Leitner:  mp3rtp fixes.  mp3rtp is a standalone program which will encode and stream with RTP.
  • Robert Hegemann:  Information written to stderr displaying exactly which type of lowpass filter (if any) is being used.
  • Iwasa Kazmi:  mpglib (the mpg123 decoder) scsfi decoding fixes.
  • Takehiro Tominaga:  More mpglib scsfi decoding fixes.

  • Mark Taylor: Fixed bug with lowpass filters when using VBR with a 64kbs or lower min bitrate setting.
  • Takehiro Tominaga:  more efficient huffman encoding splitting.

LAME 3.60beta   January 9 2000

  • Mark Taylor: Distribution now comes with self test.  Needs work to be automated, see 'make test' in Makefile.
  • Mark Taylor: AAC spreading function now the default
  • Gabriel Bouvigne: updated HTML docs
  • Felix von Leitner: compute correct file length from Xing header (if present) when input file is a mp3 file
  • Felix von Leitner: mp3rtp (standalone) program now included.  Not yet tested.  mp3rtp ip:port:ttl  <infile>   /dev/null will stream directly to ip:port using  RTP.

LAME 3.59beta  January 4 2000

  • Takehiro Tominaga:  --noath option.  Disables ATH maskings.
  • Gabriel Bouvigne:  updated HTML docs.
  • Iwasa Kazmi:  makefile fixes
  • Mark Taylor:  Fixed bug where first frame of data was always overwritten with 0's.  Thanks to 'gol'
  • Mark Taylor:  bug fixes in mid/side masking ratios (thanks to Menno Bakker)
  • Mark Taylor:  replaced norm_l, norm_s table data with formulas.

LAME 3.58beta  December 13 1999

  • Segher Boessenkool:  More accurate quantization procedure!  Enabled with -h.
  • Mathew Hendry, Acy Stapp and Takehiro Tominaga: ASM optimizations for quantize_xrpow and quantize_xrpow_ISO.
  • Chuck Zenkus:  "encoder inside" logo on web page
  • Mark Taylor:   a couple people have asked for this.   Allow LAME to overide VBR_min_bitrate if analog_silence detected.   Analog_silence defined a la Robert:   energy  < ATH.
  • An Van Lam: Valid bitrates were being printed for layer 2, not layer 3!
  • Ethan Yeo:  Makefile.MSVC updated
  • Mark Stephens:  updated all MSVC project files
  • Robert Hegemann:  lowpass and highpass filters can be enabled with --lowpass, --highpass
  • Mark Taylor:  MS switching is now smoother: ms_ratio average over 4 granules
  • Takehiro Tominaga:  Scalefactor pre-emphasis fixed (and now turned back on)
  • Takehiro Tominaga:  Bug in M/S maskings:  switch to turn on stereo demasking code was buggy.

LAME 3.57beta  November 22 1999

  • Sigbjørn Skjæret, patch to allow encoding from 8bit input files when using LIBSNDFILE
  • Mark Taylor: Automatic downsampling to nearest valid samplerate.
  • Mark Taylor: Scalefactor bands demarked on MDCT plot in frameanalyzer
  • Mark Taylor: Scalefactor preemphasis disabled for now.   The algorithm was often doing more harm than good.

LAME 3.56beta  November 19 1999

  • Kimmo Mustonen: portabilty code cleanup.
  • Vladimir Marek: id3 genre patch.
  • Conrad Sanderson: new applypatch script.
  • Mark Taylor: Initial window type now "STOP_TYPE" to reduce initial attenuation.  This is needed because the new encoder delay is so short.  With a NORM_TYPE, the first 240 samples would be attenuated.
  • Mark Taylor: Padding at end of file now adjusted (hopefully!) to produce as little padding as possible while still guarantee all input samples are encoded.
  • Takehiro Tominaga:  Reduced shortblock extra bit allocation formulas by 10% since new huffman coding is at least 10% more efficient.

LAME 3.55beta  November 11 1999

  • Albert Faber:  updated BladeEnc.dll
  • Mark Taylor: Simple lowpass filter added to linear downsampling routine.
  • Nils Faerber: updated man page.
  • Mark Taylor: All floating point variables are delcared FLOAT or  FLOAT8.  Change the definition of FLOAT8 in machine.h to run at 32bit preceision.
  • Mark Taylor: Bug (introduced in 3.54beta) in stereo->mono downsampling fixed.

LAME 3.54beta  November 8 1999

  • Mark Taylor: Encoder delay is now 48 samples.  Can be adjusted to 1160 to sync with FhG (see ENCDELAY in encoder.h)  This is kind of amazing, since if Takehiro put his MDCT/filterbank routine in a decoder, we could have a total  delay of only 96 samples.
  • Mark Taylor: More inconstancies found and fixed in MPEG2 tables.
  • Mark Taylor: Resampling from an MP3 input file now works.  But we still dont have a lowpass filter so dont expect good results.

LAME 3.53beta  November 8 1999

  • Takehiro Tominaga:  Fixed MPEG2 problem in new MDCT routines.  Takehiro's combined filterbank/MDCT routine is now the default.  Removes all buffering from psymodel.c and the filterbanks/MDCT routines.

LAME 3.52beta  November 8 1999

  • By permission of copyright holders of all GPL code in LAME,  all GPL code is now released under a modified version of the LGPL (see the README file)
  • By popular demand, all C++ comments changed to C style comments
  • Mark Taylor: Linear resampling now works.  Use --resample to set an output samplerate different from the input samplerate.  (doesn't seem to work with mp3 input files, and there is no lowpass filter, so dont expect good results just yet)
  • Takehiro Tominaga:  Faster Huffman encoding routines
The following changes are disabled because of MPEG2 problems.  But to try them, set MDCTDELAY=48 in encoder.h, instead of MDCTDELAY=528.:
  • Takehiro Tominaga:  New MDCT routines with shorter delay (48 samples instead of 528) and even faster than the old routines.
  • Takehiro Tominaga:  Removed extra buffering in psymodel.c

LAME 3.51  November 7 1999

  • Takehiro Tominaga: Bug in quantize.c absolute threshold of hearing calculation for non-44.1 kHz input files.

LAME 3.50  November 1 1999

  • LAME 3.37beta becomes official LAME 3.50 release

LAME 3.37beta  November 1 1999

  • Lionel Bonnet:  Found severe bug in MPEG2 Short block SNR.
  • Sergey Sapelin:  VBR Toc improvement.
  • Sergey Dubov: fskip() routine
  • Conrad Sanderson: replacement for filterbank.c.   Not much faster but amazingly simpler.

LAME 3.36beta  October 25 1999

  • Albert Faber:  more MSVC and BladeDLL updates
  • Kimmo Mustonen:  Much code cleanup and Amiga updates
  • Anton Oleynikov: Borland C updates
  • Mark Taylor: More stdin fixes:  For some reason, forward fseek()'s would fail when used on pipes even though it is okay with redirection from "<". So I changed all the forward fseek()'s to use fread().  This should improve stdin support for wav/aiff files.  If you know the input file is raw pcm, you can still use the '-r' option to avoid *all* seeking of any kind.

LAME 3.35beta  October 21 1999

  • Leonid Kulakov:  Serious bug in MPEG2 scalefactor band tables fixed.
  • Portability patches from:  Anton Oleynikov, Sigbjørn Skjæret, Mathew Hendry, Richard Gorton
  • Alfred Weyers: compiler options, updated timestatus.
  • Albert Faber:  BladeDll and other updates (new machine.h).
  • Monty:  updated Makefile to fix gcc inline math bug.

LAME 3.34beta  October 12 1999

  • Mark Taylor: Bug fixed:  minimum bitrate in VBR mode could be ignored for a few frames.
  • Mark Taylor: New (minor) VBR tunings.
  • Tim Ruddick: New wav/aiff header parsing routines.  Better parsing and fewer fseek()'s.
  • Anton Oleynikov:  patches to work with Borland C
  • Gabriel Bouvigne:  Experimental voice option enabled with --voice

LAME 3.33beta  October 11 1999

  • Robert Hegemann: RH VBR mode now the default and only VBR mode.  The new code will always quantize to 0 distortion and the quality is increased by reducing the masking from the psy-model.  -X0 is still the default for now.
  • Robert Hegemann: new -X5 mode
  • Mathew Hendry: New timing code, removes the need for HAVETIMES
  • Mathew Hendry:  assembler quantize_xrpow for Windows
  • Iwasa Kazmi:  stdin/stdout patch for Windows
  • Mark Taylor: New option: "--athonly" will ignore the psy-model output and use only the absolute threshold of hearing for the masking.

LAME 3.32beta  October 8 1999

  • Takehiro Tominaga:  faster long block spreading function convolution for non 44.1 kHz sampling frequencies, and faster short block spreading function convolution for all sampling frequencies.
  • Takehiro Tominaga:  Completly rewritten huffman table selection and count_bits().  More efficient table selection results in many more bits per frame.
  • Takehiro Tominaga:  More efficient scalefac compress setting.
  • Mike Cheng: new calc_noise2()
  • Alfred Weyers: patch for timestatus() seconds rollover

LAME 3.31beta  September 28 1999

  • Albert Faber:  updated his BladeDLL code.  This allows LAME to be compiled into a BladeEnc compatiable .dll.
  • Mike Cheng: faster l3psycho_ener() routine.
  • Sigbjørn Skjæret: more code cleanup.

LAME  3.30beta  September 27 1999

  • Conrad Sanderson:  ID3 tag code added (type 'lame' for instructions)
  • new mdct.c from Mike Cheng (no faster, but much cleaner code)
  • Mathew Hendry: Microsoft nmake makefile and a couple other changes for MSVC
  • More modulization work:  One input sound file interface handles mp3's, uncompressed audio, with or without LIBSNDFILE.  Fixes (hopefully) a bunch of file I/O bugs introduced in 3.29 (Mark Taylor)
  • LAME will now print valid samplerate/bitrate combinations (Mark Taylor)
  • stdin/stdout fix for OS/2 (Paul Hartman)
  • For mp3 input files, totalframes estimated based on filesize and first frame bitrate. (Mark Taylor)
  • Updated all functions with new style prototypes.  (Sigbjørn Skjæret)

LAME 3.29beta  September 21 1999

  • Bug in bigv_bitcount fixed.  Loop.c was overestimating the number of bits needed, resulting in wasted bits every frame.  (Leonid A. Kulakov)
  • Bug in *_choose_table() fixed   These routines would not sellect the optimal Huffman table in some cases.   (Leonid A. Kulakov)
  • Tuning of ATH normalization (macik)
  • Removed unused variables and fixed function prototypes (Sigbjørn Skjæret)
  • Sami Farin sent a  .wav  file that  LAME built in support choked on.   I added a slightly more sophisticated wav header parsing to handle this, but if you have trouble, use libsndfile.
  • Resampling hooks and options added.  Buffering and resampling routines need to be written.
  • LAME will now take an mp3 file as input.  When resampling code is working, LAME will be able to (for example) convert a high bitrate stereo mp3 to a low bitrate mono mp3 for streaming.

LAME 3.28beta  September 15 1999

  • Serious bug fixed in high frequency MDCT coefficients.  Huffman coding was reversing the order of the count1 block quadruples.   (Leonid A. Kulakov)
  • nint() problems under Tru64 unix fixed and preprocessor variable HAVE_NINT removed.  (Bob Bell)
  • Compiler warning fixes and code cleanup   (Sigbjørn Skjæret, Lionel Bonnet)
  • USAGE file now includes suggestions for downsampling.  For low bitrate encodings, proper downsampling can give dramatically better results.  (John Hayward-Warburton)

LAME 3.27beta  September 12 1999

  • Several bugs in encode.c and l3bitstream.c fixed by Lionel Bonnet.
  • Bugs in new VBR (#define RH) formula for mono input file and mid/side encoding fixed.

LAME 3.26beta  September 10 1999

  • The "-m m" option (mono .mp3 file) will automatically mix left and right channels if the input file is stereo.  (Alfred Weyers)
  • New quant_compare algorithm (method for deciding which of two quantizations is better) enabled with -X4 (Greg Maxwell)
  • New mid/side VBR bit allocation formula.  Mid channel bits are set by the quality requirements, and then the side channel uses a reduced number of bits (in a proportion coming from the fixed bitrate code).  This might not be optimal, but it should be pretty good and no one knows what the optimal solution should be.  (Greg Maxwell)
  • New VBR (#define RH) tunings based on detailed listening tests by Macik and Greg Maxwell.
  • Sigbjørn Skjæret fixed several compiler warnings (which turned out to be potential bugs)
  • Takehiro Tominaga fixed a low bitrate bug in reduce_side()
  • Alfred Weyers fixed some buffer overflows.
  • New ATH (absolute threshold of hearing) formula replaces buggy ISO code, and adds  analog silence treatment  (removal of coefficients below below ATH).   These are turned on by default but have not been fully tested.  (Robert Hegemann)
  • Bug in short block spreading function fixed.  (Robert Hegemann)

LAME 3.25beta  August 22 1999

  • Sigbjørn Skjæret fixed a zero byte malloc call.  This bug  was introduced in 3.24 and causes problems on non Linux systems.
  • Bit allocation routines would sometimes allocate more than 4095 bits to one channel of one granule.  A couple of people reported problems that might be caused by this, especially at higher bitrates.
  • Nils Faerber updated the man page and fixed many of the compiler warnings.

LAME 3.24beta   August 15 1999

  • This release contains the following new code (for developers) which is disabled by default:
  • Robert Hegemann:  Completely overhauled VBR code.  Now computes exact number of bits required for the given qualty and then quantized with the appropriate bitrate.
  • Several new quantization quality measures.

LAME 3.23beta  August 8 1999

  • Very nice continuously updated VBR histogram display from Iwasa Kazmi.  (disabled with --nohist).
  • More modulerization work.  The encoding engine can now be compiled into libmp3lame, but the interface is awkward.
  • Bug fixed in FFT Hann window formula (Leonid A. Kulakov).
  • New LAME logo on the download page.  Created by Chris Michalisles.
  • Several VBR algorithm improvements from Robert Hegemann.  New quantization noise metrics and VBR quality measure takes into account mid/side encoding.  Should produce smaller files with the same quality, especially when using jstereo.

LAME 3.22beta  July 27 1999

  • Downsampling (stereo to mono) bug with MPEG2 fixed.  (Mike Oliphant)
  • Downsampling now merges L & R channels - before it only took the L channel.
  • More modularization and code cleanup from Albert Faber and myself.
  • Input filesize limit removed for raw pcm input files.  For other file types, LAME will still only read the first 2^32 samples, (27 hours of playing time at 44.1 kHz).

LAME 3.21beta  July 26 1999

  • Correct Mid/Side masking thresholds for JSTEREO mode!  This is enabled with -h.  It  makes LAME about 20% slower since it computes psycho-acoustics for L,R Mid and Side channels.
  • "Analog silence" threshold added.  Keeps VBR from upping the bitrate during very quite passages.  (Robert.Hegemann)
  • New VBR quality setting from Robert Hegemann.  It is based on the idea that distortion at lower bit rates sounds worse than at higher bitrates, and so the allowed distortion (VBR quality setting) is proportional to the bitrate.  Because of this, default minimum bitrate is now 32kbs.
  • Expermental subblock gain code enabled with -Z.
  • New "-r" option for raw pcm input files.  With -r, LAME will not do any fseek()'s or look for wav and aiff headers on the input file.
  • Bug fixes in mp3x (frame analyzer) for viewing frames near end of the file.
  • Bug fixed to allow setting the sampling rate of raw pcm input files.

LAME 3.20beta  July 19 1999

  • Bug in get_audio.c fixed.  Libsndfile wrappers would not compile (Miguel Revilla  Rodriguez)
  • Nils Faerber found some unitialized variables and some wierd extranous computations in filter_subband, now fixed.  This was causing seg faults on some machines.

LAME 3.19beta  July 18 1999

  • Oops!  Robert Hegemann immediatly found a bug in the new  (old -Z option) quantization code.  calc_noise1 was not returning tot_noise, so non ms-stereo frames were buggy.

LAME 3.18beta  July 17 1999

  • Many psycho-acoustic bug fixes.  Dan Nelson discovered a bug in MPEG2: For short blocks, the code assumes 42 partition bands.  MPEG1 sometimes has less, MPEG2 can have more.  In MPEG1, this bug would not have effected the output if your compiler initializes static variables to 0 on creation.  In MPEG2 it leads to array out-of-bounds access errors. Finally, there was a related bug in MPEG1/MPEG2, short & long blocks where the energy above 16 kHz was all added to partition band 0. (the lowest frequeny partition band!)
  • The -Z option (Gabriel Bouvigne's idea of using total quantization noise to choose between two quantizations with the same value of "over") is now the default.  I believe this helps remove the trilling sound in Jan's testsignal4.wav.  The quality of testsignal2.wav and testsignal4.wav are now better than Xing and getting closer to FhG.
  • Bug fixes in frame & sample count for downsampling mode. (ben "jacobs")
  • Patches to improve modulization.  (ben "jacobs")

LAME 3.17beta  July 11 1999

  • substantial code cleanup towards goal of making LAME more modular.

LAME 3.16beta  July 11 1999

  • New tunings of window switching, and better bit allocation based on pe.  (Jan Rafaj.  improves both testsignal2.wav and testsignal4.wav).
  • Bug in mid/side quantization when side channel was zero fixed.  (Albert Faber)
  • Removed some extranous computations in l3psy.c (Robert Hegemann)
  • More detailed timing status info, including hours display. (Sakari Ailus) and percentage indicator (Conrad Sanderson).
  • Window_subband and calc_noise1,calc_noise2 speedups.  Quantize_xrpow speedup should be significant on non GNU/intel systems. (Mike Cheng)
  • Better initial guess for VBR bitrate.  Should speed up VBR encoding.  (Gabriel Bouvigne)
  • More advanced .wav header parsing.  fixes bugs involving click in first frame. (Robert.Hegemann)
  • Correct filesize and total frame computation when using LIBSNDFILE (ben "jacobs")
  • Click in last frame (buffering problem) when using libsndfile fixed.
  • Audio I/O code overhauled.  There is now a uniform audio i/o interface to libsndfile or the LAME built in wav/aiff routines.  All audio i/o code localized to get_audio.c.

LAME 3.15beta

  • times()/clock() problem fixed for non-unix OS.  (Ben "Jacobs")
  • Fixed uninitialized pe[] when using fast mode.  (Ben "Jacobs")

LAME 3.13  June 24 1999

  • Patches for BeOS from Gertjan van Ratingen.
  • Makefile info for OS/2 Warp 4.0  (from dink.org).
  • Status display now based on wall clock time, not cpu time.
  • mem_alloc no longer allocates twice as much memory as needed (Jan Peman).

3.12pre9

  • Updated BLADEDLL code to handle recent changes (Albert Faber).
  • Bug fixed in parsing options when not using GTK (Albert Faber).
  • MPEG2 Layer III psycho acoustics now working.
  • Improved huffman encoding Chris Matrakidis. (10% faster).  I dont know how he finds these improvements!  LAME with full quality now encodes faster than real time on my PII 266.
  • Fixed time display when encoding takes more than 60 minutes.

3.12pre8

  • New mid/side stereo criterion.  LAME will use mid/side stereo only when the difference between L & R masking thresholds (averaged over all scalefactors) is less then 5db.  In several test samples it does a very good job mimicking the FhG encoder.
  • Bug in mid/side stereo fixed:  independent variation of mid & side channel scalefactors disabled.  Because of the way outer_loop is currently coded, when encoding mid/side coefficietns using left/right thresholds, you have to vary the scalefactors simultaneously.
  • Bug in side/mid energy ratio calculation fixed. (Thanks to Robert Hegemann)
  • Default mode is stereo (not jstereo) if bitrate is chosen as 192kbs or higher.  Tero Auvinen first pointed out that FhG seems to think at 160kbs, their encoder is so good it doesn't need jstereo tricks. Since LAME is not as good as FhG, I am going to claim that 192kbs LAME is so good it doens't need jstereo tricks, and thus it is disabled by default.
  • WAV header parsing for big-endian machines, and automatic detection of big-endian machines.  (Thanks to  Sigbjørn Skjæret).
  • added 56 sample delay to sync LAME with FhG.
  • MP3x (frame analyzer) can now handle MPEG2 streams.

3.12pre7

  • MPEG2 layer III now working!  lower bit rates (down to 8kbs) and 3 more sampling frequencies:  16000, 22050, 24000Hz. Quality is poor - the psy-model does not yet work with these sampling frequencies.
  • Fixed "ERROR: outer_loop(): huff_bits < 0." bug when using VBR.
  • bash and sh scripts to run LAME on multiple files now included.  (from Robert Hegemann and Gerhard Wesp respectively)
  • bug fix in encoding times for longer files from  (Alvaro Martinez Echevarria)
  • yet another segfault in the frame analyzer fixed.
  • ISO psy-model/bit allocation routines removed.  This allowed makeframe() to be made much simpler, and most of the complicated buffering is now gone. Eventually I would like the encoding engine to be a stand alone library.

3.12pre6

  • Better VBR tuning.  Find minimum bitrate with distortion less than the allows maximum.  A minimum bit rate is imposed on frames with short blocks (where the measured distortion can not be trusted).   A minimum frame bitrate can be specified with -b, default=64kbs.
  • LIBSNDFILE support.  With libsndfile, LAME can encode almost all sound formats.  Albert Faber did the work for this, including getting libsndfile running under win32.
  • CRC checksum now working!   (Thanks to Johannes Overmann )
  • frame analyzer will now work with mono .mp3 files
  • more code tweeks from Jan Peman.
  • Compaq-Alpha(Linux) fixes and speedups from Nils Faerber.
  • Faster bin_search_StepSize from Juha Laukala.
  • Faster quantize() from Mike Cheng
  • Faster quantize_xrpow() from Chris Matrakidis.  xrpow_flag removed since this option is now on by default.
  • Fixed .wav header parsing from Nils Faerber.
  • Xing VBR frame info header code from Albert Faber.   "Xing" and "LAME 3.12" embedded in first frame.
  • Bug in VBR bit allocation based on "over" value fixed.

LAME 3.11  June 3 1999

  • Almost all warnings (-Wall) now fixed!  (Thanks to Jan Peman)
  • More coding improvements from Gabriel Bouvigne and Warren Toomey.
  • VBR  (variable bit rate).   Increases bit rate for short blocks and for frames where the number of bands containing audible distortion is greater than a given value.  Much tuning needs to be done.
  • Patch to remove all atan() calls from James Droppo.

LAME 3.10 May 30 1999

  • Fast mode (-f)  disables psycho-acoustic model for real time encoding on older machines.  Thanks to Lauri Ahonen who first sent a patch for this.
  • New bit reservoir usage scheme to accommodate the new pre-echo detection formulas.
  • Tuning of AWS and ENER_AWS pre-echo formulas by Gabriel Bouvigne and myself.  They work great!  now on by default.
  • In jstereo, force blocktypes for left & right channels to be identical.  FhG seems to do this.  It can be disabled with "-d".
  • Patches to compile MP3x under win32 (Thanks to Albert Faber).
  • bin_serach_stepsize limited to a quantizationStepSize of  -210 through 45.
  • outer_loop()  will now vary Mid & Side scalefactors independently.  Can lead to better quantizations, but it is slower (twice as many quantizations to look at).  Running with "-m f" does not need this and will run at the old speed
  • Bug in inner_loop would allow quantizations larger than allowed.  (introduced in lame3.04, now fixed.)
  • Updated HTML documentation from Gabriel Bouvigne.
  • Unix  man page from William Schelter.
  • numlines[] bug fixed.  (Thanks to Rafael Luebbert, MPecker author).
  • Quantization speed improvements from Chirs Matrakidis.
  • When comparing quantizations with the same number of bands with audible distortion, use the one with the largest scalefactors, not the first one outer_loop happened to find.
  • Improved defination of best quantization when using -f (fast mode).
  • subblock code now working.  But no algorithm to choose subblock gains yet.
  • Linux now segfaults on floating point exceptions.  Should prevent me from releasing binaries that crash on other operating systems.

LAME 3.04 May 22 1999

  • Preliminary documentation from Gabriel Bouvigne.
  • I wouldn't have thought it was possible, but now there are even more speed improvements from Chris Matrakidis!  Removed one FFT when using joint stereo, and many improvements in loop.c.
  • "Fake" ms_stereo mode renamed "Force" ms_stereo since it forces mid/side stereo on all frames.  For some music this is said to be a problem, but for most music mode is probably better than the default jstereo because it uses specialized mid/side channel masking thresholds.
  • Small bugs in Force ms_stereo mode fixed.
  • Compaq Alpha fixes from Nathan Slingerland.
  • Some new experimental pre-echo detection formulas in l3psy.c (#ifdef AWS and #ifdef ENER_AWS, both off by default.  Thanks to Gabriel Bouvigne and Andre Osterhues)
  • Several bugs in the syncing of data displayed by mp3x (the frame analyzer) were fixed.
  • highq (-h) option added.  This turns on things (just one so far) that should sound better but slow down LAME.

LAME 3.03 May 18 1999

  • Faster (20%) & cleaner FFT (Thanks to Chris Matrakidis  http://www.geocities.com/ResearchTriangle/8869/fft_summary.html)
  • mods so it works with VC++ (Thanks to Gabriel Bouvigne, www.mp3tech.org)
  • MP3s marked "original" by default  (Thanks to Gabriel Bouvigne, www.mp3tech.org)
  • Can now be compiled into a BladeEnc compatible .DLL   (Thanks to  Albert Faber, CDex author)
  • Patches for "silent mode" and stdin/stdout  (Thanks to Lars Magne Ingebrigtsen)
  • Fixed rare bug: if a long_block is sandwiched between two short_blocks, it must be changed to a short_block, but the short_block ratios have not been computed in l3psy.c.  Now always compute short_block ratios just in case.
  • Fixed bug with initial quantize step size when many coefficients are zero.  (Thanks to Martin Weghofer).
  • Bug fixed in MP3x display of audible distortion.
  • improved status display (Thanks to Lauri Ahonen).

LAME 3.02 May 12 1999

  • encoder could use ms_stereo even if channel 0 and 1 block types were different.  (Thanks to Jan Rafaj)
  • added -k option to disable the 16 kHz cutoff at 128kbs.  This cutoff is never used at higher bitrates. (Thanks to Jan Rafaj)
  • modified pe bit allocation formula to make sense at bit rates other than 128kbs.
  • fixed l3_xmin initialization problem which showed up under FreeBSD.  (Thanks to Warren Toomey)

LAME 3.01 May 11 1999

  • max_name_size increased to 300  (Thanks to Mike Oliphant)
  • patch to allow seeks on input file (Thanks to Scott Manley)
  • fixes for mono modes (Thanks to everyone who pointed this out)
  • overflow in calc_noise2 fixed
  • bit reservoir overflow when encoding lots of frames with all zeros  (Thanks to Jani Frilander)

LAME 3.0 May 10 1999

  • added GPSYCHO (developed by Mark Taylor)
  • added MP3x (developed by Mark Taylor)
  • LAME now maintained by Mark Taylor

November 8 1998

  • Version 2.1f released
  • 50% faster filter_subband() routine in encode.c contributed by James Droppo

November 2 1998

  • Version 2.1e released.
  • New command line switch -a auto-resamples a stereo input file to mono.
  • New command line switch -r resamples from 44.1 kHz to 32 kHz [this switch doesn't work really well. Very tinny sounding output files. Has to do with the way I do the resampling probably]
  • Both of these were put into the ISO code in the encode.c file, and are simply different ways of filling the input buffers from a file.

October 31 1998

  • Version 2.1d released
  • Fixed memory alloc in musicin.c (for l3_sb_sample)
  • Added new command line switch (-x) to force swapping of byte order
  • Cleaned up memory routines in l3psy.c. All the mem_alloc() and free() routines where changed so that it was only done once and not every single time the routine was called.
  • Added a compile time switch -DTIMER that includes all timing info. It's a switch for the time being until some other people have tested on their system. Timing code has a tendency to do different things on different platforms.

October 18 1998

  • Version 2.1b released.
  • Fixed up bug: all PCM files were being read as WAV.
  • Played with the mem_alloc routine to fix crash under amigaos (just allocating twice as much memory as needed). Might see if we can totally do without this routine. Individual malloc()s where they are needed instead
  • Put Jan Peman's quality switch back in. This reduces quality via the '-q <int>' switch. Fun speedup which is mostly harmless if you're not concerned with quality.
  • Compiling with amiga-gcc works fine

October 16 1998

  • Version 2.1a released. User input/output has been cleaned up a bit. WAV file reading is there in a very rudimentary sense ie the program will recognize the header and skip it, but not read it. The WAV file is assumed to be 16bit stereo 44.1 kHz.

October 6 1998

  • Version 2.1 released with all tables now incorporated into the exe. Thanks to Lars Magne Ingebrigtseni

October 4 1998

  • In response to some concerns about the quality of the encoder, I have rebuilt the encoder from scratch and carefully compared output at all stages with the output of the unmodified ISO encoder.
  • Version 2.0 of LAME is built from the ISO source code (dist10), and incorporates modifications from myself and the 8hz effort. The output file from LAME v2.0 is identical to the output of the ISO encoder for my test file. Since I do not have heaps of time, I left the ISO AIFF file reader in the code, and did not incorporate a WAV file reader.
  • Added section on quality.

October 1 1998

  • Updated web page and released LAME v1.0

Up to September 1998

Working on the 8hz source code...

  • Patched the 8hz source code
  • 45% faster than original source (on my freebsd p166).
    • m1 - sped up the mdct.c and quantize() functions [MDCTD, MDCTD2, LOOPD]
    • m2 - sped up the filter_subband routine using Stephane Tavenard's work from musicin [FILTST]
    • m2 - minor cleanup of window_subband [WINDST2]
    • m2 - Cleaned up a few bits in l3psy.c. Replaced a sparse matrix multiply with a hand configured unrolling [PSYD]
    • m3 - (amiga only) Added in the asm FFT for m68k (based on sources from Henryk Richter and Stephane Tavenard)
    • m4 - raw pcm support back in
    • m5 - put in a byte-ordering switch for raw PCM reading (just in case)
    • m6 - reworked the whole fft.c file. fft now 10-15% faster.
    • m7 - totally new fft routine. exploits fact that this is a real->complex fft. About twice as fast as previous fastest fft (in m6). (C fft routine is faster than the asm one on an m68k!)
    • m8
      • Now encodes from stdin. Use '-' as the input filename. Thanks to Brad Threatt
      • Worked out that the 1024point FFT only ever uses the first 6 phi values, and the first 465 energy values. Saves a bunch of calculations.
      • Added a speed-up/quality switch. Speed is increased but quality is decreased slightly. My ears are bad enough not to be able to notice the difference in quality at low settings :). Setting '-q 1' improves speed by about 10%. '-q 100' improves speed by about 26%. Enoding of my test track goes from 111s (at default '-q 0') to 82s (at -q 100). Thanks to Jan Peman for this tip.
    • m9 - fixed an error in l3psy.c. numlines[] is overwritten with incorrect data. Added a new variable numlines_s[] to fix this. Thanks again to Jan Peman.
    • m10 - Down to 106 seconds by selecting a few more compiler options. Also added a pow20() function in l3loop.c to speed up (ever so slightly) calls to pow(2.0, x)
    • m11
      • No speedups. Just cleaned up some bits of the code.
      • Changed K&R prototyping to 'normal' format. Thanks to Steffan Haeuser for his help here.
      • Changed some C++ style comments to normal C comments in huffman.c
      • Removed the #warning from psy_data.h (it was getting annoying!)
      • Removed reference in bitstream.c to malloc.h. Is there a system left where malloc.h hasn't been superceded by stdlib.h?
  • In Progess:
    • my PSYD hack for the spreading functions is only valid for 44.1 kHz - Should really put in a "if freq = 44.1 kHz" switch for it. Someone might want to extend the speedup for 48 and 32 kHz.
    • Putting in Jan Peman's quantanf_init speedup.

SettingBrief description
Input options
By default, LAME accepts a PCM audio sample inside a .WAV container as the input file, in 8, 16, 24 and 32 bits integer and in IEEE FLOAT. If it is compiled with libsndfile, then it also supports the extra formats that the library supports.
There is also support for RAW PCM data and and piped input
-For piped/streamed Input, use "-" as the input and/or output file name.
--out-dir pathIf no explicit output file is specified, a file will be written at given path. Ignored when using piped/streamed input
--mp1input1Input file is an MPEG layer I file. Implicit if extension is .mp1
--mp2input1Input file is an MPEG layer II file. Implicit if extension is .mp2
--mp3input1Input file is an MPEG layer III file. Implicit if extension is .mp3
--scale numberScale input (multiply PCM data) by number.
--scale-l numberScale channel 0 (left) input (multiply PCM data ) by number
--scale-r numberScale channel 1 (right) input (multiply PCM data) by number
--gain numberapply Gain adjustment in decibels, range -20.0 to +12.0.

--signed / --unsigned Input is signed (default) or unsigned
--bitwidth w Input bit width is w (default 16)
-x Force byte-swapping of input stream
--little-endian / --big-endian Input is little-endian (default) or big-endian
-aDownmix from stereo to mono file for mono encoding. Needed with RAW input for the -mm mode to do the downmix.

Variable Bit Rate (VBR)
-V numberQuality setting for VBR. default number=4.
Decimal values can be specified, like: 4.51
0=highest quality, bigger files. 9.999=lowest quality, smaller files
--vbr-oldUse old variable bitrate (VBR) routine
-b numberSpecify a minimum allowed bitrate. default 32 kbps (See -F setting below)

Detailed description in alphabetical order

-a Downmix

mix the stereo input file to mono and encode as mono.

This option is only needed in the case of raw PCM stereo input (because LAME cannot determine the number of channels in the input file). To encode a stereo PCM input file as mono, use "lame -m m -a"

For WAV and AIFF input files, using "-m m" will always produce a mono .mp3 file from both mono and stereo input.

--abr n Average bitrate encoding (aka Safe VBR)

turns on encoding with a targeted average bitrate of n kbps, allowing to use frames of different sizes. The allowed range of n is 8...320 kbps, you can use any integer value within that range.

--add-id3v2 Force addition of version 2 tag

Tells LAME to add the tag information as id3v2. This implies adding both, a version 1 and a version 2 tag, if the values fit on a version 1 tag. See --id3v1-only and --id3v2-only if you want a more fine-grained control.

-b n Bitrate

Codec sample frequencies (kHz) bitrates (kbps)
MPEG-1 layer III 32, 48, 44.1 32 40 48 56 64 80 96 112 128 160 192 224 256 320
MPEG-2 layer III 16, 24, 22.05 8 16 24 32 40 48 56 64 80 96 112 128 144 160
MPEG-2.5 layer III 8, 12, 11.025 8 16 24 32 40 48 56 64

The bitrate to be used. Default is 128kbps in MPEG1 (64 for mono), 64kbps in MPEG2 (32 for mono) and 32kbps in MPEG2.5 (16 for mono).

When used with variable bitrate encodings (VBR), -b specifies the minimum bitrate to use. This is useful only if you need to circumvent a buggy hardware device with strange bitrate constrains. (You will need the -F setting too for digital silence).
Default for ABR/VBR is the minimum allowed bitrate for the MPEG version. (i.e. no limit)

-B n Max bitrate

see also option "-b" for allowed bitrates.

Maximum allowed bitrate when using VBR/ABR.

Using -B is NOT RECOMMENDED. A 128 kbps CBR bitstream, because of the bit reservoir, can actually have frames which use as many bits as a 320 kbps frame. ABR/VBR modes minimize the use of the bit reservoir, and thus need to allow 320 kbps frames to get the same flexibility as CBR streams. This is useful only if you need to circumvent a buggy hardware device with strange bitrate constrains.
Default value is the maximum allowed bitrate for the MPEG versio (i.e. no limit)

--big-endian Set the byte order to big-endian.

This switch tells LAME that the RAW pcm input is encoded in big-endian instead of little-endian.

--bitwidth Sets the bitwidth value

With RAW pcm input, this switch lets specify the bitwidth of the same (8 bits, 16 bits...)

-c copyright flag

mark the encoded file as copyrighted

--cbr Enforce constant bitrate encoding

This switch disables the VBR encoding. Examples:

lame -V 0 --cbr input.wav
Will encode at -b 128 (ignore completely -V and encode at default bitrate) 
lame --preset 160 --cbr
Will encode at -b 160 (ignore ABR and use the specified bitrate) 
lame --abr 200 --cbr
Will encode at -b 192 (ignore ABR and use the nearest bitrate to the one specified)

--clipdetect Clipping detection

Enable --replaygain-accurate and print a message whether clipping occurs and how far in dB the waveform is from full scale.

This option is not usable if the MP3 decoder was explicitly disabled in the build of LAME.

See also: --replaygain-accurate

--comp x Indicate a compression ratio instead of a bitrate

Use this in place of the -b setting if you prefer to indicate a compression ratio (integer value). The ratio is the value of original-filesize/desired-filesize

--decode MP3 decode capability

This uses LAME's HIP2 decoder to decode an MP3 (layers 1, 2 and 3) file to a wav file.

If -t is used (disable wav header), LAME will output raw pcm in native endian format (use -x to swap bytes).

This option is not usable if the MP3 decoder was explicitly disabled in the build of LAME.

--decode-mp3delay x Indicate a different encoder delay for decoding

When decoding an mp3 file, LAME automatically corrects for the start delay that the encoder had to put into it.
This setting lets you specify a different delay than LAME's own one, so that it is possible to compensate for the delay of mp3's generated with other encoders.

--disptime secs Update the display each secs

Use this setting to change the frequency that LAME updates the display when encoding a file. Allows decimal values (like 0.5)

-e n/5/c Write the de-emphasis flag

n = (none, default)
5 = 50/15 microseconds
c = ccitt j.17

All this does is set a flag in the bitstream. If you have a PCM input file where one of the above types of (obsolete) emphasis has been applied, you can set this flag in LAME. Then the mp3 decoder should de-emphasize the output during playback, although most decoders ignore this flag.

A better solution would be to apply the de-emphasis with a standalone utility before encoding, and then encode without -e.

-F Enforce the minimum bitrate

Enforces the minimum bitrate. Without this option, passages of analog silence will be encoded at the minimum bitrate possible (32 or 8, depending on MPEG version).

--flush Flush the output stream as soon as possible

This setting forces a flush of the data written as soon as the operation has finished. This is mostly useful in case of streams. With files, it may degrade performance, since the OS has to write to disk in smaller chunks.

--freeformat Encode to freeformat stream

LAME will produce a fixed bitrate, free format bitstream. User must specify the desired bitrate in kbps, which can be any integer between 8 and 640.

Not supported by most decoders. Compliant decoders (of which there are few) are only required to support up to 320 kbps.

Decoders knwon to handle free format:

Supports up to
MAD640 kbps
"lame --decode"640 kbps
l3dec310 kbps

--gain Apply gain in decibels.

Apply Gain adjustment in decibels, range -20.0 to +12.0. 0dBFS means no amplification.

--genre-list Print alphabetical ordered list of known genres

Tell LAME to print the list of genres with their index to be used with the --tg setting.

--highpass number Use a highpass filter when encoding

Enables a highpass filter of the specified frequency when encoding the source. Range [0.001..50]kHz or [50..50000]Hz.
This is usually not required, and the gains are usually minimal. May be useful to remove an interference signal on 50Hz or 60Hz, or a DC offset. (default: disabled)
Note: The current implementation has a minimum highpass frequency of (67.5/62)% of the sample rate (I.e. 481Hz at 44Khz).

--highpass-width width Set the width of the decaying curve.

Specify the width in Hz of the decaying curve of the highpass. Range [16..50000]Hz
The minimum (and default) width is 75% of a band's width (which is 1/64th of the sample rate).
Note: See the remark in the --highpass command above.

--id3v1-only Disable the use of id3v2.

Put it before any tag setting.
This setting tells LAME to use ID3 v1 tag only, and not create an ID3v2 even if it thinks it should.

--id3v2-only Disable the user ov id3v1.

Put it before any tag setting.
This setting tells LAME to use ID3 v2 tag only. An ID3 v1 tag would not be written.

--ignore-tag-errors Ignore tag information errors

Put it before any tag setting.
This tells lame to ignore the tag information that sees as erroneous and continue encoding without those. Without this setting, errors are reported and encoding does not start.

--license Print the license page

Prints version and license information about LAME encoder.

--little-endian Set the byte order to little-endian.

This switch tells LAME that the RAW pcm input is encoded in little-endian. It is the default setting.

--longhelp Shows the detailed help

Prints a help page with all of the command-line switches and a brief explanation of them.

--lowpass number Use a lowpass filter when encoding

Enables a lowpass filter of the specified frequency when encoding the source. Range [0.001..50]kHz or [50..50000]Hz

Using a lowpass filter helps reducing the amount of data to encode. This is important in MP3 due to a limitation in very high frequencies (>16Khz). The default value depends on the target bitrate/quality. It is not recommended to change it as a general basis.

--lowpass-width width Set the width of the decaying curve.

Specify the width in Hz of the decaying curve of the lowpass. Range [0.001..16]kHz or [16..50000]Hz
The lowpass is in the center of this curve. The minimum (and default) width is 75% of a band's width (which is 1/64th of the sample rate).

-m x Channel modes

-m mmono
-m lget only the left channel of a stereo signal for a mono output
-m rget only the right channel of a stereo signal for a mono output
-m sforced L/R stereo
-m j /
-m a		automatic switch between L/R and M/S stereo
-m fforced mid/side stereo
-m ddual (independent) channels.

MONO is the default mode for mono input files. If "-m m" is specified for a stereo input file, the two channels will be averaged into a mono signal. (Note: See comments about the -a switch for RAW PCM streams)

FORCED L/R STEREO encodes the left and the right signals independently, and gives more or less bits to each, depending on the currently available.

JOINT STEREO is the default mode of encoding. jstereo means the encoder can use (on a frame by frame basis) either L/R stereo or mid/side stereo. In mid/side stereo, the mid (L+R) and side (L-R) channels are encoded, and more bits are allocated to the mid channel than the side channel. When there isn't too much stereo separation, this effectively increases the bandwidth, so having higher quality with the same amount of bits.
Using mid/side stereo inappropriately can result in audible compression artifacts. Too much switching between mid/side and regular stereo can also sound bad. To determine when to switch to mid/side stereo, LAME uses a much more sophisticated algorithm than the one described in the ISO documentation.

FORCED MID/SIDE STEREO forces all frames to be encoded with mid/side stereo. It should only be used if you are sure every frame of the input file has very little stereo seperation.

DUAL CHANNEL mode is similar to encode the left and right as two mono signals. Its purpose was meant for Dual language streams where only one of them should be decoded. Most decoders just decode them as a stereo stream

--mp1input --mp2input --mp3input MPEG layer I, II or III input file

Assume the input file is an MP1/2/3 file. LAME will decode the input file before re-encoding it. Since MP3 is a lossy format, this is not recommended in general. But it is useful for creating low bitrate mp3s from high bitrate mp3s. If the filename ends in ".mp3" LAME will assume it is an MP3. For stdin or MP3 files which don't end in .mp3 you need to use this switch.

--noasm value Disables the specified assembler instructions

When the encoder is compiled with assembler optimizations, this setting allows to disable them at runtime (They are only enabled if the CPU supports them). The purpose of this setting is to detect problems in those optimizations, and/or check the speed difference.

--nogap file1 file2 [...] Encodes multiple continuous files.

Encodes multiple files (ordered by position) which are meant to be played gaplessly.

By default, LAME will encode the files with accurate length, but the first and last frame may contain a few erroneous samples for signals that don't fade-in/out (as is the case of continuous playback).

This setting solves that by using the samples from the next/previous file to compute the encoding.

--nogapout dir Specify a directory for the output of the files encoded with --nogap

This setting should precede --nogap, and is used to specify the alternate directory where to store the encoded files. The default one is the input file directory.

--nogaptags Enables the use of VBR tags with files encoded with --nogap

Tells LAME to put VBR tags to encoded files if they are encoded in VBR or ABR modes. Else, using the --nogap option doesn't generate it.

--nohist Disable bitrate Histogram

By default, LAME will display a bitrate histogram while producing VBR mp3 files. This will disable that feature.

--noreplaygain Disable ReplayGain analysis

By default ReplayGain analysis is enabled. This switch disables it.

See also: --replaygain-accurate, --replaygain-fast

-o non-original

Mark the encoded file as a copy

-p CRC error detection

Turn on CRC error protection. It will add a cyclic redundancy check (CRC) code in each frame, allowing to detect transmission errors that could occur on the MP3 stream. However, it takes 16 bits per frame that would otherwise be used for encoding, and then will slightly reduce the sound quality.

--pad-id3v2 Pad ID3v2 tag.

Pads the ID3v2 tag with extra 128bytes to allow it to expand.

--priority value Set process priority

(Windows and OS/2 only)

Sets the process priority for LAME while running under Windows and/or IBM OS/2. This can be very useful to avoid the system becoming slow and/or unresponsive. By setting LAME to run in a lower priority, you leave more time for the system to update basic processing (drawing windows, polling keyboard/mouse, etc). The impact in LAME's performance is minimal if you use priority 0 to 2.

The valid parameters are:

PriorityWindowsOS/2
0Low priority IDLE_PRIORITY_CLASSIDLE, delta = 0
1Medium priority IDLE_PRIORITY_CLASSIDLE, delta = +31
2Regular priority NORMAL_PRIORITY_CLASSREGULAR, delta = -31
3High priority HIGH_PRIORITY_CLASSREGULAR, delta = 0
4Maximum priority HIGH_PRIORITY_CLASSREGULAR, delta = +31

Note that if you call '--priority' without a parameter, then priority 0 will be assumed.

-q n Algorithm quality selection

Bitrate is of course the main influence on quality. The higher the bitrate, the higher the quality. But for a given bitrate, we have a choice of algorithms to determine the best scalefactors and Huffman coding (noise shaping).

For CBR, ABR and --vbr-old modes, the following table applies

-q 0Use the best algorithms (Best Huffman coding search, full outer loop, and the highest precision of several parameters).
-q 1 to -q 4Similar to -q 0 without the full outer loop and with decreasing precision of parameters the further from -q 0. -q 3 is the default
-q 5 and -q 6Same as -q 7, but enables noise shaping and increases subblock gain
-q 7 to -q 9Same as -f. Very fast, OK quality. Psychoacoustics are used for pre-echo and mid/side stereo, but no noise-shaping is done.

For the default VBR mode since LAME 3.98, the following table applies

-q 0 to -q 4include all features of the other modes and additionally use the best search when applying Huffman coding.
-q 5 and -q 6 include all features of -q7, calculate and consider actual quantisation noise, and additionally enable subblock gain.
-q 7 to -q 9This level uses a psymodel but does not calculate quantisation noise when encoding: it takes a quick guess.

--quiet Don't print any output in the screen

Disables the screen output. Useful for job processing or other times where screen output is undesirable.

-r Input file is raw pcm

Assume the input file is raw pcm. Sampling rate and mono/stereo must be specified on the command line. Without -r, LAME will perform several fseek()'s on the input file looking for WAV and AIFF headers.

Not supported if LAME is compiled to use LIBSNDFILE.

--replaygain-accurate Slightly more accurate ReplayGain analysis and finding the peak sample

Compute "Radio" ReplayGain on the decoded data stream. Find the peak sample by decoding on the fly the encoded data stream and store it in the file.

ReplayGain analysis does _not_ affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from http://www.replaygain.org/

By default, LAME performs ReplayGain analysis on the input data (after the user-specified volume scaling). This behaviour might give slightly inaccurate results because the data on the output of a lossy compression/decompression sequence differs from the initial input data. When --replaygain-accurate is specified the mp3 stream gets decoded on the fly and the analysis is performed on the decoded data stream. Although theoretically this method gives more accurate results, it has several disadvantages:

  • tests have shown that the difference between the ReplayGain values computed on the input data and decoded data is usually no greater than 0.5dB, although the minimum volume difference the human ear can perceive is about 1.0dB
  • decoding on the fly significantly slows down the encoding process
The apparent advantage is that:
  • with --replaygain-accurate the peak sample is determined and stored in the file. The knowledge of the peak sample can be useful to decoders (players) to prevent a negative effect called 'clipping' that introduces distortion into sound.

Only the "Radio" ReplayGain value is computed. It is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1.

This option is not usable if the MP3 decoder was _explicitly_ disabled in the build of LAME. (Note: if LAME is compiled without the MP3 decoder, ReplayGain analysis is performed on the input data after user-specified volume scaling).

See also: --replaygain-fast, --noreplaygain, --clipdetect

--replaygain-fast Fast ReplayGain analysis

Compute "Radio" ReplayGain of the input data stream after user-specified volume scaling and/or resampling.

ReplayGain analysis does _not_ affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from http://www.replaygain.org/

Only the "Radio" ReplayGain value is computed. It is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1.

This switch is enabled by default.

--resample n Output sampling frequency in kHz

where n = 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48

Output sampling frequency. Resample the input if necessary.

If not specified, LAME may sometimes resample automatically when faced with extreme compression conditions (like encoding a 44.1 kHz input file at 32 kbps). To disable this automatic resampling, you have to use --resample to set the output sample rate equal to the input sample rate. In that case, LAME will not perform any extra computations.

-s n Sampling frequency in kHz

where n = sampling rate in kHz.

Required for raw PCM input files. Otherwise it will be determined from the header information in the input file.

LAME will automatically resample the input file to one of the supported MP3 sample rates if necessary.

--scale arg --scale-l arg --scale-r arg Scale the amplitude of the input file

Scales input by arg. This just multiplies the PCM data (after it has been converted to floating point) by arg.

arg > 1: increase volume
arg = 1: no effect
arg < 1: reduce volume

Use with care, since most MP3 decoders will truncate data which decodes to values greater than 32768.

The l and r variants apply the scaling only to left (channel 0) or right (channel 1) respectively.

--signed Input RAW uses signed values

Use with RAW pcm to indicate if the data is signed (values centered at zero) or unsigned (all positive values). This is the default value.

--silent Don't print any output in the screen

Disables the screen output. Useful for job processing or other times where screen output is undesirable.

--space-id3v1 Use spaces for padding.

Use spaces instead of null values for padding data in an ID3v1 tag.

--strictly-enforce-ISO Strict ISO compliance

With this option, LAME will enforce the 7680 bit limitation on total frame size. This results in many wasted bits for high bitrate encodings. Some decoders need it.

-t Disable VBR tag or disable WAV header

This setting has two different uses:

When encoding to VBR, this setting disables writing the VBR Tag (also known as XING tag). This tag is embedded by default in the frame 0 of the MP3 file. It lets VBR aware players to correctly seek and compute playing times in such files.

When decoding MP3 to WAV using --decode, this flag will disable writing the WAV header. The output will be raw pcm, native endian format. Use -x to swap bytes.

-T Force the usage of the LAME tag

By default, LAME already adds a LAME tag when encoding. This setting overrides the -t setting, and implies --nogaptags.

--unsigned Input RAW uses unsigned values

Use with RAW pcm to indicate if the data is signed (values centered at zero) or unsigned (all positive values).

--usage Print the command line help.

Print the short command line help and exit.

-V n Enable VBR encoding

Encodes using the VBR algorithm, at the indicated quality.
0=highest quality, bigger files. 9.999=lowest quality, smaller files. Decimal values can be specified, like: 4.51
On average, the resulting bitrates are as follows:
SettingAverage bitrate (kbps)
0245
2190
3175
4165
5130

Using -V 7 or higher (lower quality) is not recommended. ABR usually produces better results.

--vbr-old Uses the old VBR method of encoding

Tells LAME to encode to VBR using the old (slower) method of encoding.

--verboseProgram verbosity

Print a lot of information on screen.

--version Prints the license page

Prints version and license information about LAME encoder.

-x Swap input bytes

swap bytes in the input file (and output file when using --decode). For sorting out little endian/big endian type problems. If your encodings sound like static, try this first.

-Y Ignore noise in sbf21, like CBR mode does

Allows -V2, -V1 and -V0 to not encode the highest frequencies accurately, if doing so causes disproportional increases in bitrate. This is the same that CBR and ABR modes do.
Due to the design of the MP3 format, to keep precision in the last scalefactor band, an encoder needs to increase the precision in all the bands (not only in this one).
The consequence is an increase of bitrate (+60kbps in some cases) compared to not keeping that precision. Generally, this band should allow for distortions, so using this switch shouldn't cause harm.

About LAME

LAME development started around mid-1998. Mike Cheng started it as a patch against the 8hz-MP3 encoder sources. After some quality concerns raised by others, he decided to start from scratch based on the dist10 sources. His goal was only to speed up the dist10 sources, and leave its quality untouched. That branch (a patch against the reference sources) became Lame 2.0, and not until Lame 3.81 (May 2000) the latest remainings of dist10 code were removed, making LAME no more only a patch.

The project quickly became a team project. Mike Cheng eventually left leadership and started working on tooLame, an MP2 encoder. Mark Taylor became leader and started pursuing increased quality in addition to better speed. He can be considered the initiator of the LAME project in its current form. He released version 3.0 featuring gpsycho, a new psychoacoustic model he developed.

In early 2003 Mark left project leadership, and since then the project has been lead through the cooperation of the active developers (currently 4 individuals).

Today, LAME is considered the best MP3 encoder at mid-high bitrates and at VBR1, mostly thanks to the dedicated work of its developers and the open source licensing model that allowed the project to tap into engineering resources from all around the world. Both quality and speed improvements are still happening, probably making LAME the only MP3 encoder still being actively developed.

LAME features:

  • Supports MPEG1, MPEG2 and MPEG2.52 layer III encoding.
  • Encodes in CBR (constant bitrate) and in two types of variable bitrate, VBR and ABR3, as well as freeformat.
  • Supports mono and stereo signals. Stereo signals are encoded by default with an advanced algorithm4 to maximize the quality.
  • Tuned default parameters for optimum encoding.
  • Fast. Encodes to -V 2 at 17 times realtime on a P4 2.8Ghz.
  • Uses an advanced psycho acoustic and noise shaping model improved during years.
  • Developed under the LGPL GNU license

LAME Official Logo

LAME - Constant Bit Rate

Suggested usage:

lame -b 128 input.wav output.mp3

CBR encoding is the basic encoding mode of MP3: The bitrate is kept constant across the entire file, which means the same number of bits is allocated to encode each second of audio, and internally, frames of audio data occur at regular, predictable intervals, given a predictable file size for a given duration. CBR is therefore the "opposite" of VBR.

That said, in some formats there may be some variability in the number of bits that contain actual audio information from frame to frame. This concept manifests in the bit reservoir of MP3s. In a CBR MP3, even though the frames are of a fixed size, the audio data is not necessarily distributed consistently between them; audio for one frame might use fewer bits than the frame has, so that frame adds the spare bits to a reservoir that can supplement the bits allocated to the next frame. Thus, the effective bitrate is allowed to vary somewhat in a CBR MP3, even though there is a fixed number of frames for the duration of audio. For example, for a 256kbps file, the bitrate of a single frame can be up to 320 kbps, but the frame immediately before and/or after that one would have to use fewer bits, whereas in VBR, there would be no such restriction. Consequently, the amount of variability across the entire MP3 is not as great as that afforded by VBR, but it is not insignificant; a CBR encoder that does not efficiently use the reservoir will likely produce a lower quality file than one that does.

ABR is a more flexible way to encode where filesize is important, but still giving some flexibility to choose frame sizes.

Who should use CBR

CBR is useful for people who are concerned about maintaining maximum compatibility, especially with certain streaming applications and some hardware-based decoders that don't reliably support VBR.

CBR is also useful for people who desire the ability to obtain accurate estimates of the bitrate or approximate duration of a file's decoded audio without scanning and partially decoding the entire file.

LAME Official Logo

LAME - Variable Bit Rate

Suggested usage:

lame -V2 input.wav output.mp3

In Variable Bitrate (VBR) coding, the user chooses a desired quality level instead of a bitrate. A correct implementation should be able to maintain the same quality perception, changing the bitrate to a higher or lower one whenever the audio file is more or less complex. With MP3, this is not always possible.

VBR encoding is the logical way of encoding data. General data compressors (like .zip and .rar) are VBR, as lossless codecs are as well. Being able to indicate a quality value, the encoder decides for each frame, which is the most appropiate bitrate to keep it.

The main advantage of using VBR is that the encoder will use the smallest amount of bytes needed to keep the asked quality. The inconvenience is that the file size is quite unpredictable, and can change from file to file in more than 50kbps. (or nearly double the size, with different genres and quasi-mono content)

LAME Official Logo

LAME - Average Bit Rate (ABR)

Suggested usage:

lame --abr 128 input.wav output.mp3

ABR is a mix between CBR and VBR.

Like CBR, the files will have the (approximate) bitrate specified in the commandline, and uses the CBR algorithm to compute the number of bits needed to encode each frame.

Like VBR, the files will use different frame bitrates so instead of relying on bit reservoir like CBR, each frame just uses the smallest possible bitrate that can encode it.

The difference between ABR and true VBR is in how the desired number of bits is chosen. The true VBR mode determines the number of bits based on the quantization noise. VBR figures out how many bits are needed so that the quantization noise is less than the allowed masking.

ABR mode uses the CBR formula to determine the desired number of bits. This formula is based on the perceptual entropy, which is a rough measure of how difficult the frame is to encode.

The majority of frames in a VBR MP3 produced with an ABR method is normally at or near the target bitrate chosen by the user, but each frame can still potentially vary within the normal range of 8 to 320 kbps. The ABR encoder will typically limit the range of bitrates it can choose from, or will greatly favor certain bitrates, in an effort to ensure that the average comes out near the target.

Who should use ABR

ABR encoding is desirable for users who want the general benefits of VBR (an optimum bitrate from frame to frame) but with a relatively predictable file size like they would get with constant bitrate (CBR), and a greater preference for bitrates that are near a desired target. Inevitably, some frames will be encoded with more bits than necessary, but the result will always be equal to or better than that of CBR for the target bitrate.

(Lame ain't an MP3 encoder). These audio files can be played back by popular MP3 players such as mpg123 or madplay. To read from stdin, use "\-" for . To write to stdout, use "\-" for . .SH OPTIONS Input options: .TP .B \-r Assume the input file is raw pcm. Sampling rate and mono/stereo/jstereo must be specified on the command line. For each stereo sample, LAME expects the input data to be ordered left channel first, then right channel. By default, LAME expects them to be signed integers with a bitwidth of 16 and stored in little-endian. Without .B \-r, LAME will perform several .I fseek()'s on the input file looking for WAV and AIFF headers. .br Might not be available on your release. .TP .B \-x Swap bytes in the input file (or output file when using .B \-\-decode). .br For sorting out little endian/big endian type problems.

Otherwise it will be determined from the header of the input file. LAME will automatically resample the input file to one of the supported MP3 samplerates if necessary. .TP .BI \-\-bitwidth " n" Input bit width per sample. .br .I n = 8, 16, 24, 32 (default 16) Required only for raw PCM input files. Otherwise it will be determined from the header of the input file. .TP .BI \-\-signed Instructs LAME that the samples from the input are signed (the default for 16, 24 and 32 bits raw pcm data). Required only for raw PCM input files. .TP .BI \-\-unsigned Instructs LAME that the samples from the input are unsigned (the default for 8 bits raw pcm data, where 0x80 is zero). Required only for raw PCM input files and only available at bitwidth 8. .TP .BI \-\-little-endian Instructs LAME that the samples from the input are in little-endian form. Required only for raw PCM input files. .TP .BI \-\-big-endian Instructs LAME that the samples from the input are in big-endian form. Required only for raw PCM input files. .TP .B \-\-mp1input Assume the input file is a MPEG Layer I (ie MP1) file. .br If the filename ends in ".mp1" LAME will assume it is a MPEG Layer I file. For stdin or Layer I files which do not end in .mp1 you need to use this switch. .TP .B \-\-mp2input Assume the input file is a MPEG Layer II (ie MP2) file. .br If the filename ends in ".mp2" LAME will assume it is a MPEG Layer II file. For stdin or Layer II files which do not end in .mp2 you need to use this switch. .TP .B \-\-mp3input Assume the input file is a MP3 file. .br Useful for downsampling from one mp3 to another. As an example, it can be useful for streaming through an IceCast server. .br If the filename ends in ".mp3" LAME will assume it is an MP3. For stdin or MP3 files which do not end in .mp3 you need to use this switch. .TP .BI \-\-nogap " file1 file2 ..." gapless encoding for a set of contiguous files .TP .BI \-\-nogapout " dir" output dir for gapless encoding (must precede \-\-nogap) .TP .BI \-\-out-dir " dir" If no explicit output file is specified, a file will be written at given path. Ignored when using piped/streamed input .PP Operational options: .TP .BI \-m " mode" .I mode = s, j, f, d, m, l, r Joint-stereo is the default mode for stereo files. .B (s)imple stereo (Forced LR) .br In this mode, the encoder makes no use of potentially existing correlations between the two input channels. It can, however, negotiate the bit demand between both channel, i.e. give one channel more bits if the other contains silence or needs less bits because of a lower complexity. .B (j)oint stereo .br In this mode, the encoder can use (on a frame by frame basis) either L/R stereo or mid/side stereo. In mid/side stereo, the mid (L+R) and side (L-R) channels are encoded, and more bits are allocated to the mid channel than the side channel. When there isn't too much stereo separation, this effectively increases the bandwidth, so having higher quality with the same amount of bits. Using mid/side stereo inappropriately can result in audible compression artifacts. Too much switching between mid/side and regular stereo can also sound bad. To determine when to switch to mid/side stereo, LAME uses a much more sophisticated algorithm than the one described in the ISO documentation. .B (f)orced MS stereo .br Forces all frames to be encoded with mid/side stereo. It should be used only if you are sure that every frame of the input file has very little stereo separation. .B (d)ual channel .br In this mode, the 2 channels will be totally independently encoded. Each channel will have exactly half of the bitrate. This mode is designed for applications like dual languages encoding (for example: English in one channel and French in the other). Using this encoding mode for regular stereo files will result in a lower quality encoding. .B (m)ono .br The input will be encoded as a mono signal. If it was a stereo signal, it will be downsampled to mono. The downmix is calculated as the sum of the left and right channel, attenuated by 6 dB. Also note that, if using a stereo RAW PCM stream, you need to use the -a parameter. .B (l)eft channel only .br The input will be encoded as a mono signal. If it was a stereo signal, the left channel will be encoded only. .B (r)ight channel only .br The input will be encoded as a mono signal. If it was a stereo signal, the right channel will be encoded only. .TP .B \-a Mix the stereo input file to mono and encode as mono. .br The downmix is calculated as the sum of the left and right channel, attenuated by 6 dB. This option is only needed in the case of raw PCM stereo input (because LAME cannot determine the number of channels in the input file). To encode a stereo RAW PCM input file as mono, use .B lame \-a \-m m For WAV and AIFF input files, using .B \-m m will always produce a mono .mp3 file from both mono and stereo input. .TP .B \-\-freeformat Produces a free format bitstream. With this option, you can use .B \-b with any bitrate higher than 8 kbps. However, even if an mp3 decoder is required to support free bitrates at least up to 320 kbps, many players are unable to deal with it. Tests have shown that the following decoders support free format: .br .B in_mpg123 up to 560 kbps .br .B l3dec up to 310 kbps .br .B LAME up to 640 kbps .br .B MAD up to 640 kbps .TP .B \-\-decode Uses LAME for decoding to a wav file. The input file can be any input type supported by encoding, including layer II files. LAME uses a fork of mpglib known as HIP for decoding. If .B \-t is used (disable wav header), LAME will output raw pcm in native endian format. You can use .B \-x to swap bytes order. This option is not usable if the MP3 decoder was .B explicitly disabled in the build of LAME. .TP .BI \-t Disable writing of the INFO Tag on encoding. .br This tag is embedded in frame 0 of the MP3 file. It includes some information about the encoding options of the file, and in VBR it lets VBR aware players correctly seek and compute playing times of VBR files. When .B \-\-decode is specified (decode to WAV), this flag will disable writing of the WAV header. The output will be raw pcm, native endian format. Use .B \-x to swap bytes. .TP .BI \-\-comp " arg" Instead of choosing bitrate, using this option, user can choose compression ratio to achieve. .TP .BI \-\-scale " n" .PD 0 .TP .BI \-\-scale\-l " n" .TP .BI \-\-scale\-r " n" Scales input (every channel, only left channel or only right channel) by .I n. This just multiplies the PCM data (after it has been converted to floating point) by .I n. .I n > 1: increase volume .br .I n = 1: no effect .br .I n < 1: reduce volume Use with care, since most MP3 decoders will truncate data which decodes to values greater than 32768. .PD .TP .B \-\-replaygain\-fast Compute ReplayGain fast but slightly inaccurately. This computes "Radio" ReplayGain on the input data stream after user\(hyspecified volume\(hyscaling and/or resampling. The ReplayGain analysis does .I not affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from .B http://www.replaygain.org/. Only the "RadioGain" Replaygain value is computed, it is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1. This switch is enabled by default. See also: .B \-\-replaygain\-accurate, \-\-noreplaygain .TP .B \-\-replaygain\-accurate Compute ReplayGain more accurately and find the peak sample. This computes "Radio" ReplayGain on the decoded data stream, finds the peak sample by decoding on the fly the encoded data stream and stores it in the file. The ReplayGain analysis does .I not affect the content of a compressed data stream itself, it is a value stored in the header of a sound file. Information on the purpose of ReplayGain and the algorithms used is available from .B http://www.replaygain.org/. By default, LAME performs ReplayGain analysis on the input data (after the user\(hyspecified volume scaling). This behavior might give slightly inaccurate results because the data on the output of a lossy compression/decompression sequence differs from the initial input data. When .B \-\-replaygain-accurate is specified the mp3 stream gets decoded on the fly and the analysis is performed on the decoded data stream. Although theoretically this method gives more accurate results, it has several disadvantages: .RS 8 .IP "*" 4 tests have shown that the difference between the ReplayGain values computed on the input data and decoded data is usually not greater than 0.5dB, although the minimum volume difference the human ear can perceive is about 1.0dB .IP "*" 4 decoding on the fly significantly slows down the encoding process .RE .RS 7 The apparent advantage is that: .RE .RS 8 .IP "*" 4 with .B \-\-replaygain-accurate the real peak sample is determined and stored in the file. The knowledge of the peak sample can be useful to decoders (players) to prevent a negative effect called 'clipping' that introduces distortion into the sound. .RE .RS 7 Only the "RadioGain" ReplayGain value is computed, it is stored in the LAME tag. The analysis is performed with the reference volume equal to 89dB. Note: the reference volume has been changed from 83dB on transition from version 3.95 to 3.95.1. This option is not usable if the MP3 decoder was .B explicitly disabled in the build of LAME. (Note: if LAME is compiled without the MP3 decoder, ReplayGain analysis is performed on the input data after user-specified volume scaling). See also: .B \-\-replaygain-fast, \-\-noreplaygain \-\-clipdetect .RE .TP .B \-\-noreplaygain Disable ReplayGain analysis. By default ReplayGain analysis is enabled. This switch disables it. See also: .B \-\-replaygain-fast, \-\-replaygain-accurate .TP .B \-\-clipdetect Clipping detection. Enable .B \-\-replaygain-accurate and print a message whether clipping occurs and how far in dB the waveform is from full scale. This option is not usable if the MP3 decoder was .B explicitly disabled in the build of LAME. See also: .B \-\-replaygain-accurate .TP .B \-\-preset " type | [cbr] kbps" Use one of the built-in presets. Have a look at the PRESETS section below. .B \-\-preset help gives more infos about the the used options in these presets. .TP .B \-\-noasm " type" Disable specific assembly optimizations ( .B mmx / .B 3dnow / .B sse ). Quality will not increase, only speed will be reduced. If you have problems running Lame on a Cyrix/Via processor, disabling mmx optimizations might solve your problem. .PP Verbosity: .TP .BI \-\-disptime " n" Set the delay in seconds between two display updates. .TP .B \-\-nohist By default, LAME will display a bitrate histogram while producing VBR mp3 files. This will disable that feature. .br Histogram display might not be available on your release. .TP .B -S .PD 0 .TP .B \-\-silent .TP .B \-\-quiet Do not print anything on the screen. .PD .TP .B \-\-verbose Print a lot of information on the screen. .TP .B \-\-help Display a list of available options. .PP Noise shaping & psycho acoustic algorithms: .TP .BI -q " qual" 0 <= .I qual <= 9 Bitrate is of course the main influence on quality. The higher the bitrate, the higher the quality. But for a given bitrate, we have a choice of algorithms to determine the best scalefactors and Huffman encoding (noise shaping). For CBR and ABR, the following table applies: .B -q 0: .br Use the best algorithms (Best Huffman coding search, full outer loop, and the highest precision of several parameters). .B -q 1 to q 4: .br Similar to -q 0 without the full outer loop and decreasing precision of parameters the further from q0. -q 3 is the default. .B -q 5 and -q 6: .br Same as -q 7, but enables noise shaping and increases subblock gain .B -q 7 to -q 9: .br Same as -f. Very fast, OK quality. Psychoacoustics are used for pre-echo and mid/side stereo, but no noise-shaping is done. For the default VBR mode since LAME 3.98, the following table applies : .B -q 0 to -q 4: .br include all features of the other modes and additionally use the best search when applying Huffman coding. .B -q 5 and -q 6: .br include all features of -q7, calculate and consider actual quantisation noise, and additionally enable subblock gain. .B -q 7 to -q 9 .br This level uses a psymodel but does not calculate quantisation noise when encoding: it takes a quick guess. .TP .B -h Alias of .B -q 2 .TP .B -f Alias of .B -q 7 .PP CBR (constant bitrate, the default) options: .TP .BI -b " n" For MPEG-1 (sampling frequencies of 32, 44.1 and 48 kHz) .br .I n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 For MPEG-2 (sampling frequencies of 16, 22.05 and 24 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 For MPEG-2.5 (sampling frequencies of 8, 11.025 and 12 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64 Default is 128 for MPEG1 and 64 for MPEG2 and 32 for MPEG2.5 (64, 32 and 16 respectively in case of mono). .TP .BI \-\-cbr enforce use of constant bitrate. Used to disable VBR or ABR encoding even if their settings are enabled. .PP ABR (average bitrate) options: .TP .BI \-\-abr " n" Turns on encoding with a targeted average bitrate of n kbits, allowing to use frames of different sizes. The allowed range of .I n is 8 - 310, you can use any integer value within that range. It can be combined with the .B -b and .B -B switches like: .B lame \-\-abr .I 123 .B -b .I 64 .B -B .I 192 a.wav a.mp3 which would limit the allowed frame sizes between 64 and 192 kbits. The use of .B -B is NOT RECOMMENDED. A 128 kbps CBR bitstream, because of the bit reservoir, can actually have frames which use as many bits as a 320 kbps frame. VBR modes minimize the use of the bit reservoir, and thus need to allow 320 kbps frames to get the same flexibility as CBR streams. .PP VBR (variable bitrate) options: .TP .B -v use variable bitrate .B (\-\-vbr-new) .TP .B \-\-vbr-old Invokes the oldest, most tested VBR algorithm. It produces very good quality files, though is not very fast. This has, up through v3.89, been considered the "workhorse" VBR algorithm. .TP .B \-\-vbr-new Invokes the newest VBR algorithm. During the development of version 3.90, considerable tuning was done on this algorithm, and it is now considered to be on par with the original .B \-\-vbr-old. It has the added advantage of being very fast (over twice as fast as .B \-\-vbr-old ). This is the default since 3.98. .TP .BI -V " n" 0 <= .I n <= 9.999 .br Enable VBR (Variable BitRate) and specifies the value of VBR quality (default = 4). Decimal values can be specified, like 4.51. .br 0 = highest quality. .PP ABR and VBR options: .TP .BI -b " bitrate" For MPEG-1 (sampling frequencies of 32, 44.1 and 48 kHz) .br .I n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 For MPEG-2 (sampling frequencies of 16, 22.05 and 24 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 For MPEG-2.5 (sampling frequencies of 8, 11.025 and 12 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64 Specifies the minimum bitrate to be used. However, in order to avoid wasted space, the smallest frame size available will be used during silences. .TP .BI -B " bitrate" For MPEG-1 (sampling frequencies of 32, 44.1 and 48 kHz) .br .I n = 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320 For MPEG-2 (sampling frequencies of 16, 22.05 and 24 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 For MPEG-2.5 (sampling frequencies of 8, 11.025 and 12 kHz) .br .I n = 8, 16, 24, 32, 40, 48, 56, 64 Specifies the maximum allowed bitrate. Note: If you own an mp3 hardware player build upon a MAS 3503 chip, you must set maximum bitrate to no more than 224 kpbs. .TP .B -F Strictly enforce the .B -b option. .br This is mainly for use with hardware players that do not support low bitrate mp3. Without this option, the minimum bitrate will be ignored for passages of analog silence, i.e. when the music level is below the absolute threshold of human hearing (ATH). .PP Experimental options: .TP .BI -X " n" 0 <= .I n <= 7 When LAME searches for a "good" quantization, it has to compare the actual one with the best one found so far. The comparison says which one is better, the best so far or the actual. The .B -X parameter selects between different approaches to make this decision, .B -X0 being the default mode: .B -X0 .br The criteria are (in order of importance): .br * less distorted scalefactor bands .br * the sum of noise over the thresholds is lower .br * the total noise is lower .B -X1 .br The actual is better if the maximum noise over all scalefactor bands is less than the best so far. .B -X2 .br The actual is better if the total sum of noise is lower than the best so far. .B -X3 .br The actual is better if the total sum of noise is lower than the best so far and the maximum noise over all scalefactor bands is less than the best so far plus 2dB. .B -X4 .br Not yet documented. .B -X5 .br The criteria are (in order of importance): .br * the sum of noise over the thresholds is lower .br * the total sum of noise is lower .B -X6 .br The criteria are (in order of importance): .br * the sum of noise over the thresholds is lower .br * the maximum noise over all scalefactor bands is lower .br * the total sum of noise is lower .B -X7 .br The criteria are: .br * less distorted scalefactor bands .br or .br * the sum of noise over the thresholds is lower .TP .B -Y lets LAME ignore noise in sfb21, like in CBR .PP MP3 header/stream options: .TP .BI -e " emp" .I emp = n, 5, c n = (none, default) .br 5 = 0/15 microseconds .br c = citt j.17 All this does is set a flag in the bitstream. If you have a PCM input file where one of the above types of (obsolete) emphasis has been applied, you can set this flag in LAME. Then the mp3 decoder should de-emphasize the output during playback, although most decoders ignore this flag. A better solution would be to apply the de-emphasis with a standalone utility before encoding, and then encode without .B -e. .TP .B -c Mark the encoded file as being copyrighted. .TP .B -o Mark the encoded file as being a copy. .TP .B -p Turn on CRC error protection. .br It will add a cyclic redundancy check (CRC) code in each frame, allowing to detect transmission errors that could occur on the MP3 stream. However, it takes 16 bits per frame that would otherwise be used for encoding, and then will slightly reduce the sound quality. .TP .B \-\-nores Disable the bit reservoir. Each frame will then become independent from previous ones, but the quality will be lower. .TP .B \-\-strictly-enforce-ISO With this option, LAME will enforce the 7680 bit limitation on total frame size. .br This results in many wasted bits for high bitrate encodings but will ensure strict ISO compatibility. This compatibility might be important for hardware players. .PP Filter options: .TP .BI \-\-lowpass " freq" Set a lowpass filtering frequency in kHz. Frequencies above the specified one will be cutoff. .TP .BI \-\-lowpass-width " freq" Set the width of the lowpass filter. The default value is 15% of the lowpass frequency. .TP .BI \-\-highpass " freq" Set an highpass filtering frequency in kHz. Frequencies below the specified one will be cutoff. .TP .BI \-\-highpass-width " freq" Set the width of the highpass filter in kHz. The default value is 15% of the highpass frequency. .TP .BI \-\-resample " sfreq" .I sfreq = 8, 11.025, 12, 16, 22.05, 24, 32, 44.1, 48 .br Select output sampling frequency (only supported for encoding). .br If not specified, LAME will automatically resample the input when using high compression ratios. .PP ID3 tag options: .TP .BI \-\-tt " title" audio/song title (max 30 chars for version 1 tag) .TP .BI \-\-ta " artist" audio/song artist (max 30 chars for version 1 tag) .TP .BI \-\-tl " album" audio/song album (max 30 chars for version 1 tag) .TP .BI \-\-ty " year" audio/song year of issue (1 to 9999) .TP .BI \-\-tc " comment" user-defined text (max 30 chars for v1 tag, 28 for v1.1) .TP .BI \-\-tn " track[/total]" audio/song track number and (optionally) the total number of tracks on the original recording. (track and total each 1 to 255. Providing just the track number creates v1.1 tag, providing a total forces v2.0). .TP .BI \-\-tg " genre" audio/song genre (name or number in list) .TP .BI \-\-tv " id=value" Text or URL frame specified by id and value (v2.3 tag). User defined frame. Syntax: \-\-tv "TXXX=description=content" .TP .B \-\-add-id3v2 force addition of version 2 tag .TP .B \-\-id3v1-only add only a version 1 tag .TP .B \-\-id3v2-only add only a version 2 tag .TP .B \-\-id3v2-latin1 add following options in ISO-8859-1 text encoding. .TP .B \-\-id3v2-utf16 add following options in unicode text encoding. .TP .B \-\-space-id3v1 pad version 1 tag with spaces instead of nulls .TP .B \-\-pad-id3v2 same as \-\-pad-id3v2-size 128 .TP .B \-\-pad-id3v2-size "num" adds version 2 tag, pad with extra "num" bytes .TP .B \-\-genre-list print alphabetically sorted ID3 genre list and exit .TP .B \-\-ignore-tag-errors ignore errors in values passed for tags, use defaults in case an error occurs .PP Analysis options: .TP .B \-g run graphical analysis on . can also be a .mp3 file. (This feature is a compile time option. Your binary may for speed reasons be compiled without this.) .SH ID3 TAGS LAME is able to embed ID3 v1, v1.1 or v2 tags inside the encoded MP3 file. This allows to have some useful information about the music track included inside the file. Those data can be read by most MP3 players. Lame will smartly choose which tags to use. It will add ID3 v2 tags only if the input comments won't fit in v1 or v1.1 tags, i.e. if they are more than 30 characters. In this case, both v1 and v2 tags will be added, to ensure reading of tags by MP3 players which are unable to read ID3 v2 tags. .SH ENCODING MODES LAME is able to encode your music using one of its 3 encoding modes: constant bitrate (CBR), average bitrate (ABR) and variable bitrate (VBR). .TP .B Constant Bitrate (CBR) This is the default encoding mode, and also the most basic. In this mode, the bitrate will be the same for the whole file. It means that each part of your mp3 file will be using the same number of bits. The musical passage being a difficult one to encode or an easy one, the encoder will use the same bitrate, so the quality of your mp3 is variable. Complex parts will be of a lower quality than the easiest ones. The main advantage is that the final files size won't change and can be accurately predicted. .TP .B Average Bitrate (ABR) In this mode, you choose the encoder will maintain an average bitrate while using higher bitrates for the parts of your music that need more bits. The result will be of higher quality than CBR encoding but the average file size will remain predictable, so this mode is highly recommended over CBR. This encoding mode is similar to what is referred as vbr in AAC or Liquid Audio (2 other compression technologies). .TP .B Variable bitrate (VBR) In this mode, you choose the desired quality on a scale from 9 (lowest quality/biggest distortion) to 0 (highest quality/lowest distortion). Then encoder tries to maintain the given quality in the whole file by choosing the optimal number of bits to spend for each part of your music. The main advantage is that you are able to specify the quality level that you want to reach, but the inconvenient is that the final file size is totally unpredictable. .SH PRESETS The .B \-\-preset switches are aliases over LAME settings. To activate these presets: .PP For VBR modes (generally highest quality): .TP .B \-\-preset medium This preset should provide near transparency to most people on most music. .TP .B \-\-preset standard This preset should generally be transparent to most people on most music and is already quite high in quality. .TP .B \-\-preset extreme If you have extremely good hearing and similar equipment, this preset will generally provide slightly higher quality than the .B standard mode. .PP For CBR 320kbps (highest quality possible from the .B \-\-preset switches): .TP .B \-\-preset insane This preset will usually be overkill for most people and most situations, but if you must have the absolute highest quality with no regard to filesize, this is the way to go. .PP For ABR modes (high quality per given bitrate but not as high as VBR): .TP .B \-\-preset " kbps" Using this preset will usually give you good quality at a specified bitrate. Depending on the bitrate entered, this preset will determine the optimal settings for that particular situation. While this approach works, it is not nearly as flexible as VBR, and usually will not attain the same level of quality as VBR at higher bitrates. .TP .B cbr If you use the ABR mode (read above) with a significant bitrate such as 80, 96, 112, 128, 160, 192, 224, 256, 320, you can use the .B \-\-preset cbr " kbps" option to force CBR mode encoding instead of the standard ABR mode. ABR does provide higher quality but CBR may be useful in situations such as when streaming an MP3 over the Internet may be important. .SH EXAMPLES .LP Fixed bit rate jstereo 128kbs encoding: .IP .B lame \-b .I 128 sample.wav sample.mp3 .LP Fixed bit rate jstereo 128 kbps encoding, highest quality: .IP .B lame \-q 0 \-b .I 128 sample.wav sample.mp3 .LP To disable joint stereo encoding (slightly faster, but less quality at bitrates <= 128 kbps): .IP .B lame \-m .I s sample.wav sample.mp3 .LP Variable bitrate (use \-V n to adjust quality/filesize): .IP .B lame \-V .I 2 sample.wav sample.mp3 .LP Streaming mono 22.05 kHz raw pcm, 24 kbps output: .IP .B cat .I inputfile .B | lame \-r \-m .I m .B \-b .I 24 .B \-s .I 22.05 \- \- .B > .I output .LP Streaming mono 44.1 kHz raw pcm, with downsampling to 22.05 kHz: .IP .B cat .I inputfile .B | lame \-r \-m .I m .B \-b .I 24 .B \-\-resample .I 22.05 \- \- .B > .I output .LP Encode with the .B standard preset: .IP .B lame \-\-preset standard .I sample.wav sample.mp3 .SH BUGS .PP Probably there are some. .SH SEE ALSO .BR mpg123 (1) , .BR madplay (1) , .BR sox (1) .SH AUTHORS .nf LAME originally developed by Mike Cheng and now maintained by Mark Taylor, and the LAME team.

This library is a Microsoft(R) DirectShow(R) wrapper filter for LAME library. It adds DirectShow interface to the library and two property pages so you can tune some encoding parameters. We are interested to hear from you, when you use this package as part of another project. Filter Homepage http://www.elecard.com/products/layer3encoder.shtml Vitaly Ivanov vitaly.ivanov@elecard.net.ru NOTE: 1st: build dx9sdk/Samples/DShow/BaseClasses Project 2nd: copy resulting strmbase.lib (or strmbasd.lib for debug support) into LAME's DShow folder 3rd: add the BaseClasses directory path to the Visual Studio Include and Library directory search path lists i.e. for Visual Studio 6 choose: Tools -> Options -> Directories 4th: build LAME .DLL builds (if you didn't yet) 5th: build LAME DShow Filter TROUBLESHOOTING FAQ: Q. When trying to open a workspace file (.dsw), I get an "empty" workspace (i.e. there are no source files listed) and/or when trying to open a project file (.dsp), I get a "This makefile was not generated by Developer Studio" error. A. Often, this can be caused by having UNIX line breaks (LF) in the .dsw and .dsp files, as opposed to Windows line breaks (CR\LF). It is interesting to note that .dsw and .dsp files are just text files; you can open them up in any text editor. If you open the .dsw and .dsp files in a text editor that can't handle UNIX line breaks (namely Notepad) you will probably see big, black squares at the end of lines. You can "fix" this error by following this procedure. 1) Do NOT let Microsoft Visual C++ attempt to fix the problem! Press "No" when prompted. 2) Open the .dsw and .dsp files in a text editor that understands UNIX line breaks. WordPad is one and it is available with most copies of Windows. 3) Once open, simply re-save the file (In WordPad, make sure you set the Save As type to "Text Document"). All UNIX line breaks should then be automatically converted to Windows line breaks. lame-3.100/dshow/Mpegac.def000644 001751 001751 00000001770 10256755271 017102 0ustar00netchildnetchild000000 000000 ; ; LAME MP3 encoder for DirectShow ; ; Copyright (c) 2000-2005 Marie Orlova, Peter Gubanov, Vitaly Ivanov, Elecard Ltd. ; ; This library is free software; you can redistribute it and/or ; modify it under the terms of the GNU Library General Public ; License as published by the Free Software Foundation; either ; version 2 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.

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

Based off of Michael Hipp's mpglib 0.2a , with many improvements by the lame development team (see AUTHORS). The interface to the library is based off of vorbisfile. If you add mp3 support to your app using this library it should be a snap to add Ogg Vorbis support as well. This isn't as fast as mpg123 will be for decoding as none of it is in assmbler. Seeking currently isn't implemented. From mpglib's orginal README: ============================= PLEASE NOTE: This software may contain patented algorithms (at least patented in some countries).

Here's ## why we pick this rather obscure method: ## - Don't want to use -MD because we'd like the dependencies to end ## up in a subdir. Having to rename by hand is ugly. ## (We might end up doing this anyway to support other compilers.) ## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like ## -MM, not -M (despite what the docs say). Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object.

This is because the block type of the previous granule can only be determined after we have computed the psycho acoustics for the following granule.

Mapping from frequency to barks is given by freq2bark() scalefactor bands: The spectrum (frequencies) are broken into SBMAX "scalefactor bands". Thes bands are determined by the MPEG ISO spec. In the noise shaping/quantization code, we allocate bits among the partition bands to achieve the best possible quality partition bands: The spectrum is also broken into about 64 "partition bands". Each partition band is about .34 barks wide. There are about 2-5 partition bands for each scalefactor band. LAME computes all psycho acoustic information for each partition band. Then at the end of the computations, this information is mapped to scalefactor bands. The energy in each scalefactor band is taken as the sum of the energy in all partition bands which overlap the scalefactor band. The maskings can be computed in the same way (and thus represent the average masking in that band) or by taking the minmum value multiplied by the number of partition bands used (which represents a minimum masking in that band). */ /* The general outline is as follows: 1. compute the energy in each partition band 2. compute the tonality in each partition band 3. compute the strength of each partion band "masker" 4. compute the masking (via the spreading function applied to each masker) 5. Modifications for mid/side masking. Each partition band is considiered a "masker". The strength of the i'th masker in band j is given by: s3(bark(i)-bark(j))*strength(i) The strength of the masker is a function of the energy and tonality. The more tonal, the less masking. LAME uses a simple linear formula (controlled by NMT and TMN) which says the strength is given by the energy divided by a linear function of the tonality. */ /* s3() is the "spreading function". It is given by a formula determined via listening tests. The total masking in the j'th partition band is the sum over all maskings i. It is thus given by the convolution of the strength with s3(), the "spreading function." masking(j) = sum_over_i s3(i-j)*strength(i) = s3 o strength where "o" = convolution operator. s3 is given by a formula determined via listening tests. It is normalized so that s3 o 1 = 1. Note: instead of a simple convolution, LAME also has the option of using "additive masking" The most critical part is step 2, computing the tonality of each partition band. LAME has two tonality estimators. The first is based on the ISO spec, and measures how predictiable the signal is over time. The more predictable, the more tonal. The second measure is based on looking at the spectrum of a single granule. The more peaky the spectrum, the more tonal. By most indications, the latter approach is better. Finally, in step 5, the maskings for the mid and side channel are possibly increased. Under certain circumstances, noise in the mid & side channels is assumed to also be masked by strong maskers in the L or R channels.

It can also work with the Windows2000/ME/XP/2003 DDK: http://www.microsoft.com/ddk/ Alternatively, the required headers are also available in CYGWIN+w32api, MINGW32 or Wine : http://www.cygwin.com/ http://www.mingw.org/ http://www.winehq.com/ If you do not have a ddk, you should be able to use the alternative msacmdrv.h provided with this ACM codec. It is not used by default because it would probably broke any real DDK already installed. --------------- Define ENABLE_DECODING if you want to use the decoding (alpha state, doesn't decode at the moment, so use it only if you plan to develop) --------------- To release this codec you will need : - lameACM.acm (result of the build process) - lameACM.inf - lame_acm.xml (where the initial configuration is stored) ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/ACM/ACM.h��������������������������������������������������������������������������������000644 �001751 �001751 �00000006550 10544042236 015242� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������/** * * Lame ACM wrapper, encode/decode MP3 based RIFF/AVI files in MS Windows * * Copyright (c) 2002 Steve Lhomme <steve.lhomme at free.fr> * * 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.

XML stands for "eXtensible Markup Language." It allows you to create your own document markups. Where HTML does a very good job of marking documents for browsers, XML allows you to define any kind of document markup, for example a document that describes a "to do" list for an organizer application. XML is a very structured and convenient format. All those random file formats created to store application data can all be replaced with XML. One parser for everything. There are different ways to access and interact with XML data. TinyXml uses a Document Object Model, meaning the XML data is parsed into a tree objects that can be browsed and manipulated, and then written back to disk. You can also construct an XML document from scratch with C++ objects and write this to disk. TinyXml is designed to be easy and fast. It is one header and three cpp files. Simply add these to your project and off you go. There is an example to get you started. It is released under the ZLib license, so you can use it in open source or commercial code. It attempts to be a flexible parser, but with truly correct and compliant XML output (with the exception of the character set, below.) TinyXml should compile on any reasonably C++ system. It does not rely on exceptions or RTTI, and only uses the STL string class. <h2> What it doesn't do. </h2> It doesn’t parse or use DTDs (Document Type Definitions) or XSL’s (eXtensible Stylesheet Language.) It is limited to the ASCII character set. There are other parsers out there (check out www.sourceforge.org, search for XML) that are much more fully featured. But they are also much bigger, take longer to set up in your project, have a higher learning curve, and often have a more restrictive license. If you are working with browsers or have more complete XML needs, TinyXml is not the parser for you. <h2> Code Status. </h2> Currently in use, TinyXml is looking pretty stable. If you find bugs, send them in and we'll get them straightened out as soon as possible. There are some areas of improvement; please check sourceforge if you are interested in working on TinxXml. <h2> Changes between version 1 and 2 </h2> <h3> Entities </h3> TinyXml recognizes the pre-defined "entity references", meaning special characters. Namely: @verbatim & & < < > > " " ' ‘ @endverbatim These are recognized when the XML document is read, and translated to there ASCII equivalents. For instance, text with the XML of: @verbatim Far & Away @endverbatim will have the Value() of "Far & Away" when queried from the TiXmlText object, but will be written back to the XML stream/file as an entitity. TiXml will ignore unknown entities and the @verbatim "&#x" @endverbatim entities, and leave them unprocessed. <h3> Streams </h3> TiXml has been modified to support both C (FILE) and C++ (operator <<,>>) streams. There are some differences that you may need to be aware of. C style output: - based on FILE* - the Print() and SaveFile() methods Generates formatted output, with plenty of white space, intended to be as human-readable as possible. They are very fast, and tolerant of ill formed XML documents. For example, an XML document that contains 2 root elements and 2 declarations, will print. C style input: - based on FILE* - the Parse() and LoadFile() methods A fast, tolerant read. Use whenever you don't need the C++ streams. C++ style ouput: - based on std::ostream - operator<< Generates condensed output, intended for network transmission rather than readability. Depending on your system's implementation of the ostream class, these may be somewhat slower. (Or may not.) Not tolerant of ill formed XML: a document should contain the correct one root element. Additional root level elements will not be streamed out. C++ style input: - based on std::istream - operator>> Reads XML from a stream, making it useful for network transmission. The tricky part is knowing when the XML document is complete, since there will almost certainly be other data in the stream. TinyXml will assume the XML data is complete after it reads the root element. Also not that operator>> is somewhat slower than Parse, due to both implementation of the STL and limitations of TinyXml. <h3> White space </h3> The world simply does not agree on whether white space should be kept, or condensed. For example, pretend the '_' is a space, and look at "Hello____world". HTML, and at least some XML parsers, will interpret this as "Hello_world". They condense white space. Some XML parsers do not, and will leave it as "Hello____world". (Remember to keep pretending the _ is a space.) It's an issue that hasn't been resolved to my satisfaction. TinyXml supports both motifs. Call TiXmlBase::SetCondenseWhiteSpace( bool ) to set the desired behavior. The default is to condense white space. If you change the default, you should call TiXmlBase::SetCondenseWhiteSpace( bool ) before making any calls to Parse XML data, and I don't recommend changing it after it has been set. <h2> Using and Installing </h2> To Compile and Run xmltest: A Linux Makefile and a Windows Visual C++ .dsp file is provided. Simply compile and run. It will write the file demotest.xml to your disk and generate output on the screen. It also tests walking the DOM by printing out the number of nodes found using different techniques. The Linux makefile is very generic and will probably run on other systems, but is only tested on Linux. You no longer need to run 'make depend'. The dependecies have been hard coded. To Use in an Application: Add tinyxml.cpp, tinyxml.h, tinyxmlerror.cpp, and tinyxmlparser.cpp to your project or make file. That's it! It should compile on any reasonably compliant C++ system. You do not need to enable exceptions or RTTI for TinyXml. <h2> Where it may go. </h2> At this point, I'm focusing on tightening up remaining issues. Bug fixes (though comfortably rare) and minor interface corrections. There are some "it would be nice if..." items. I'll keep those posted as tasks on SourceForge. (www.sourceforge.net/projects/tinyxml) <h2> How TinyXml works. </h2> An example is probably the best way to go. Take: @verbatim <?xml version="1.0" standalone=‘no’> <?-- Our to do list data --> <ToDo> <Item priority="1"> Go to the <bold>Toy store!</bold></Item> <Item priority="2"> Do bills</Item> </ToDo> @endverbatim It’s not much of a To Do list, but it will do. To read this file (say "demo.xml") you would create a document, and parse it in: @verbatim TiXmlDocument doc( "demo.xml" ); doc.LoadFile(); @endverbatim And it’s ready to go. Now let’s look at some lines and how they relate to the DOM. <?xml version="1.0" standalone=‘no’> The first line is a declaration, and gets turned into the TiXmlDeclaration class. It will be the first child of the document node. This is the only directive/special tag parsed by by TinyXml. Generally directive targs are stored in TiXmlUnknown so the commands won’t be lost when it is saved back to disk. <?-- Our to do list data --> A comment. Will become a TiXmlComment object. <ToDo> The ToDo tag defines a TiXmlElement object. This one does not have any attributes, but will contain 2 other elements, both of which are items. <Item priority="1"> Creates another TiXmlElement which is a child of the "ToDo" element. This element has 1 attribute, with the name ‘priority’ and the value ‘1’. Go to the A TiXmlText. This is a leaf node and cannot contain other nodes. It is a child of the ‘Item" Element. <bold> Another TiXmlElement, this one a child of the "Item" element. Etc. Looking at the entire object tree, you end up with: @verbatim TiXmlDocument "demo.xml" TiXmlDeclaration "version='1.0'" "standalone=‘no’" TiXmlComment " Our to do list data" TiXmlElement "ToDo" TiXmlElement "Item" Attribtutes: priority = 1 TiXmlText "Go to the " TiXmlElement "bold" TiXmlText "Toy store!" TiXmlElement "Item" Attributes: priority=2 TiXmlText "bills" @endverbatim <h2> Contributors </h2> Thanks very much to everyone who sends suggestions, bugs, ideas, and encouragement. It all helps, and makes this project fun. A special thanks to the contributors on the web pages that keep it lively. So many people have sent in bugs and ideas, that rather than list here I try to give credit due in the "changes.txt" file. <h2> Documentation </h2> The documentation is build with Doxygen, using the 'dox' configuration file. <h2> License </h2> TinyXml is released under the zlib license: This software is provided 'as-is', without any express or implied warranty.

(Hopefully.) Changes in version 1.0.2 - Minor documentation fixes. Changes in version 1.0.3 - After nodes are added to a document, they return a pointer to the new node instead of a bool for success. - Elements can be constructed with a value, which is the element name. Every element must have a value or it will be invalid, but the code changes to enforce this are not fully in place. Changes in version 1.1.0 - Added the TiXmlAttributeSet class to pull the attributes into a seperate container. - Moved the doubly liked list out of XmlBase. Now XmlBase only requires the Print() function and defines some utility functions. - Moved errors into a seperate file. (With the idea of internationalization to the other latin-1 languages.) - Added the "NodeType" - Fixed white space parsing in text to conform with the standard. Basically, all white space becomes just one space. - Added the TiXmlDeclaration class to read xml declarations. Changes in version 1.2.0 - Removed the factory. The factory was not really in the spirit of small and simple, confused the code, and was of limited value. - Added FirstChildElement and NextSiblingElement, because they are such common functions. - Re-wrote the example to test and demonstrate more functionality. Changes in version 1.2.1 - Fixed a bug where comments couldn't be inside elements. - Loading now clears out existing XML rather than appending. - Added the "Clear" method on a node to delete all its children. Changes in version 1.2.2 - Fixed TiXmlAttribute::Previous actually returning "next." Thanks to Rickard Troedsson for the bug fix. Changes in version 1.2.3 - Added the TIXML prefix to the error strings to resolve conflicts with #defines in OS headers. Thanks to Steve Lhomme. - Fixed a delete buf that should be a delete [] buf. Thanks to Ephi Sinowitz. Changes in version 1.2.4 - ReplaceChild() was almost guarenteed to fail. Should be fixed, thanks to Joe Smith. Joe also pointed out that the Print() functions should take stream references: I agree, and would like to overload the Print() method to take either format, but I don't want to do this in a dot release. - Some compilers seem to need an extra <ctype.h> include. Thanks to Steve Lhomme for that. Changes in version 2.0.0 - Made the ToXXX() casts safe if 'this' is null. When "LoadFile" is called with a filename, the value will correctly get set. Thanks to Brian Yoder. - Fixed bug where isalpha() and isalnum() would get called with a negative value for high ascii numbers. Thanks to Alesky Aksenov. - Fixed some errors codes that were not getting set. - Made methods "const" that were not. - Added a switch to enable or disable the ignoring of white space. ( TiXmlDocument::SetIgnoreWhiteSpace() ) - Greater standardization and code re-use in the parser. - Added a stream out operator. - Added a stream in operator. - Entity support. TODO CDATA. Support for "generic entity" #xxx thing. ����������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������lame-3.100/ACM/tinyxml/tinyxml.cpp������������������������������������������������������������������000644 �001751 �001751 �00000044042 07453556352 020421� 0����������������������������������������������������������������������������������������������������ustar�00netchild������������������������netchild������������������������000000 �000000 ������������������������������������������������������������������������������������������������������������������������������������������������������������������������/* Copyright (c) 2000 Lee Thomason (www.grinninglizard.com) This software is provided 'as-is', without any express or implied warranty.
