An abstract soundfile decoder. SDL_sound is a library that handles the decoding of several popular sound file formats, such as .WAV and .MP3. It is meant to make the programmer's sound playback tasks simpler. The programmer gives SDL_sound a filename, or feeds it data directly from one of many sources, and then reads the decoded waveform data back at her leisure. If resource constraints are a concern, SDL_sound can process sound data in programmer-specified blocks. Alternately, SDL_sound can decode a whole sound file and hand back a single pointer to the whole waveform. SDL_sound can also handle sample rate, audio format, and channel conversion on-the-fly and behind-the-scenes, if the programmer desires. Please check the website for the most up-to-date information about SDL_sound: http://icculus.org/SDL_sound/ SDL_sound _REQUIRES_ Simple Directmedia Layer (SDL) to function, and cannot be built without it. You can get SDL from http://www.libsdl.org/. SDL_sound has only been tried with the SDL 1.2 series, but may work on older versions. Reports of success or failure are welcome. Some optional external libraries that SDL_sound can use and where to find them: SMPEG (used to decode MP3s): http://icculus.org/smpeg/ libvorbisfile (used to decode OGGs): http://www.xiph.org/ogg/vorbis/ libSpeex (used to decode SPXs): http://speex.org/ libFLAC (used to decode FLACs): http://flac.sourceforge.net/ libModPlug (used to decode MODs, etc): http://modplug-xmms.sourceforge.net/ libMikMod (used to decode MODs, etc, too): http://www.mikmod.org/ Experimental QuickTime support for the Mac is included, but has not been integrated with the build system, and probably doesn't work with QuickTime for Windows. These external libraries are OPTIONAL. SDL_sound will build and function without them, but various sound file formats are not supported unless these libraries are available. Unless explicitly disabled during initial build configuration, SDL_sound always supports these file formats internally: - Microsoft .WAV files (uncompressed and MS-ADPCM encoded). - Creative Labs .VOC files - Shorten (.SHN) files - Audio Interchange format (AIFF) files - Sun Audio (.AU) files - MIDI files - MP3 files (internal decoder, different than the one SMPEG uses) - Raw waveform data Building/Installing: Please read the INSTALL document.

The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir.

This gives you a nice abstraction for getting sound into your * game or application; just feed it to SDL_sound, and it will handle * decoding and converting, so you can just pass it to your SDL audio * callback (or whatever). Since it gets data from an SDL_RWops, you can get * the initial sound data from any number of sources: file, memory buffer, * network connection, etc. * * As the name implies, this library depends on SDL: Simple Directmedia Layer, * which is a powerful, free, and cross-platform multimedia library. It can * be found at http://www.libsdl.org/ * * Support is in place or planned for the following sound formats: * - .WAV (Microsoft WAVfile RIFF data, internal.) * - .VOC (Creative Labs' Voice format, internal.) * - .MP3 (MPEG-1 Layer 3 support, via the SMPEG and mpglib libraries.) * - .MID (MIDI music converted to Waveform data, internal.) * - .MOD (MOD files, via MikMod and ModPlug.) * - .OGG (Ogg files, via Ogg Vorbis libraries.) * - .SPX (Speex files, via libspeex.) * - .SHN (Shorten files, internal.) * - .RAW (Raw sound data in any format, internal.) * - .AU (Sun's Audio format, internal.) * - .AIFF (Audio Interchange format, internal.) * - .FLAC (Lossless audio compression, via libFLAC.) * * (...and more to come...) * * Please see the file COPYING in the source's root directory. * * \author Ryan C.

If there was an unrecoverable error, * sample->flags & SOUND_SAMPLEFLAG_ERROR will be set, which you regular * decoding loop can pick up. * * On success, ERROR, EOF, and EAGAIN are cleared from sample->flags. * * \param sample The Sound_Sample to seek. * \param ms The new position, in milliseconds from start of sample. * \return nonzero on success, zero on error. Specifics of the * error can be gleaned from Sound_GetError(). * * \sa Sound_Rewind */ SNDDECLSPEC int SDLCALL Sound_Seek(Sound_Sample *sample, Uint32 ms); #ifdef __cplusplus } #endif #endif /* !defined _INCLUDE_SDL_SOUND_H_ */ /* end of SDL_sound.h ... */ SDL_sound-1.0.3/Makefile.am0000644000175000017500000000217311001710256012316 00000000000000lib_LTLIBRARIES = libSDL_sound.la SUBDIRS = decoders . playsound libSDL_soundincludedir = $(includedir)/SDL libSDL_soundinclude_HEADERS = \ SDL_sound.h libSDL_sound_la_SOURCES = \ SDL_sound.c \ SDL_sound_internal.h \ alt_audio_convert.c \ alt_audio_convert.h \ audio_convert.c \ extra_rwops.c \ extra_rwops.h if USE_TIMIDITY TIMIDITY_LIB = decoders/timidity/libtimidity.la else TIMIDITY_LIB = endif if USE_MPGLIB MPGLIB_LIB = decoders/mpglib/libmpglib.la else MPGLIB_LIB = endif libSDL_sound_la_LDFLAGS = \ -release $(LT_RELEASE) \ -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE) libSDL_sound_la_LIBADD = \ decoders/libdecoders.la \ $(TIMIDITY_LIB) $(MPGLIB_LIB) EXTRA_DIST = \ CREDITS \ COPYING \ CHANGELOG \ CWProject.sit \ PBProjects.tar.gz \ borland.zip \ Doxyfile \ VisualC dist-hook: mkdir $(distdir)/docs echo "Docs are generated with the program "Doxygen" (http://www.doxygen.org/)," >> $(distdir)/docs/README echo " or can be read online at http://icculus.org/SDL_sound/docs/" >> $(distdir)/docs/README echo >> $(distdir)/docs/README rm -rf `find $(distdir) -type d -name ".svn"` SDL_sound-1.0.3/Makefile.in0000644000175000017500000006420611002724260012335 00000000000000# Makefile.in generated by automake 1.9.6 from Makefile.am. # @configure_input@ # Copyright (C) 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, # 2003, 2004, 2005 Free Software Foundation, Inc. # This Makefile.in 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. @SET_MAKE@ srcdir = @srcdir@ top_srcdir = @top_srcdir@ VPATH = @srcdir@ pkgdatadir = $(datadir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ top_builddir = . am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd INSTALL = @INSTALL@ install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ target_triplet = @target@ DIST_COMMON = README $(am__configure_deps) \ $(libSDL_soundinclude_HEADERS) $(srcdir)/Makefile.am \ $(srcdir)/Makefile.in $(srcdir)/config.h.in \ $(top_srcdir)/configure COPYING INSTALL TODO compile \ config.guess config.sub depcomp install-sh ltmain.sh missing subdir = .

Those licensing terms are not reprinted here, but can be found on the web easily. Other external libraries (such as Ogg Vorbis, SMPEG, etc) have their own licenses which you should be aware of before including the related code in your configuration. Most (if not all) are also under the LGPL, but are external projects and we've got no control over them. If you want to use SDL_sound under a closed-source license, please contact Ryan (icculus@icculus.org), and we can discuss an alternate license for money to be distributed between the contributors to this work, but I'd encourage you to abide by the LGPL, since the usual concern is whether you can use this library without releasing your own source code (you can). ------------------- GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change.

SDL_sound-1.0.3/INSTALL0000644000175000017500000000724511001707505011323 00000000000000Building is pretty easy. Please read README, too, as it duplicates and expands upon much of this information. ALL PLATFORMS: Please understand your rights and mine: read the text file COPYING in the root of the source tree. If you can't abide by it, delete this source tree now. The best documentation for the SDL_sound API is SDL_sound.h. It is VERY heavily commented, and makes an excellent, in-depth reference to all the functions. The official API reference is generated from this file with a program called "Doxygen" (http://www.doxygen.org/) Borland C++ Builder for Linux (Kylix 3): Unzip the "borland.zip" file in the root of the source tree and use the project files in the newly-created Borland/k3 directory. Makefiles for the command line compiler are in Borland/freebcc ... Unix: (If you pulled the source from CVS), run ./bootstrap run ./configure --help, and see if there's any options you need. Rerun configure with those options. If this is confusing to you, just run ./configure with no options: the defaults are generally decent, and configure is usually smart enough to figure out what's best.. If configuration succeeded, run "make". Run "make install" as root to install the library for use on your system. This should work for most Unix-style systems, including Linux, *BSD, BeOS, and MacOS X. Reports of success and failure are welcome. MacOS 9 users: Included with the source is CWProject.sit, which contains project files for CodeWarrior 5.0 and later. MacOS X command line tools: You can use the "UNIX" instructions above if you like the command line tools. MacOS X Project Builder: If you prefer to use Project Builder, use the project files included with this source: PBProjects.tar.gz...unpack it in the root of the SDL_sound folder. This archive contains several external libraries you would have to download/install manually if you used the command line tools (these libraries are for extra decoders, and are NOT required for SDL_sound to function...however, without them, the number of sound formats you can decode is reduced.) BeOS: You can use the "UNIX" instructions above, too. Win32 Visual C: For Visual C, use: http://icculus.org/SDL_sound/downloads/sdl_sound_visualc_srcs.zip ...and unzip it somewhere. This zipfile has a complete copy of the SDL_sound sources, Visual C project files, and several external libraries, too. This zip is everything you should need, and you can scrap this copy of the source. Win32 Cygwin: Cygwin users can try their luck with the Unix build instructions in this tarball instead. Win32 Borland C++ Builder 6: Unzip the "borland.zip" file in the root of the source tree and use the project files in the newly-created Borland/bcb6 directory. Makefiles for the command line compiler are in Borland/freebcc ... these are unmaintained, and you will need to go find the external libraries you want to use (those that wish to maintain these project files should contact me). If building is successful, there will be a shared library and a binary called "playsound". Windows CE (Microsoft PocketPC): You'll need Microsoft's PocketPC development environment, and this zipfile: http://icculus.org/SDL_sound/downloads/SDL_soundCE.zip Unzip that into the root of this source tree. The new "wce" directory has project files, and the source to some of the external decoders is included. Note that not all of the decoders are supported on PocketPC (but please, do send us patches if you get them working!) OTHER PLATFORMS: Send me patches, and instructions, and I'll list them here. Consider joining the SDL_sound mailing list. Details are at: http://icculus.org/SDL_sound/ --ryan.

Decoders still needing seek() method: (If decoder can't seek, clean up the stub and report an error.) - mikmod.c - shn.c - mpglib.c - quicktime.c General stuff TODO: - Hack on the experimental audio conversion routines. - Handle compression and other chunks in WAV files. - Handle compression and other chunks in AIFF-C files. Quicktime stuff that'd be cool, but isn't crucial: - Integrate decoders/quicktime.c with build system (for OS X)? - Make decoders/quicktime.c more robust. - Make decoders/quicktime.c work on win32? - There's no seek() method. Ongoing: - look for "FIXME"s in the code. /* end of TODO ... */ SDL_sound-1.0.3/compile0000755000175000017500000000717311001705443011647 00000000000000#! /bin/sh # Wrapper for compilers which do not understand `-c -o'. scriptversion=2005-05-14.22 # Copyright (C) 1999, 2000, 2003, 2004, 2005 Free Software Foundation, Inc. # Written by Tom Tromey . # # This program 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 2, 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.

This allows a simple and perfomant implemantation of the sample rate converters. Depending of the operation mode, two layouts for the RateConverterBuffer.inbuffer are possible: in the Loop Mode: ... T-4 T-3 T-2 T-1 H+0 H+1 H+2 H+3 H+4 ... | linp, finp in the Single Mode (non Loop): ... T-4 T-3 T-2 T-1 0 0 0 ... 0 0 0 H+0 H+1 H+2 H+3 H+4 ... | | linp finp The RateConverterBuffer allows an accurate attack and decay of the filters in the rate Converters. The pointer finp are actually shifted against the depicted position so that on the first invocation of the rate converter the input of the filter is nearly complete in the zero region, only one input value is used. After the calculation of the first output value, the pointer are incremented or decremented depending on down or up conversion and the first two input value are taken into account. This procedure repeats until the filter has processed all zeroes. The distance of the pointer movement is stored in flength, always positive. Further a pointer cinp to the sample buffer itself is stored. The pointer to the sample buffer is shifted too, so that on the first use of this pointer the filter is complete in the sample buffer. The pointer moves over the sample buffer until it reaches the other end. The distance of the movement is stored in clength.

Converted all text encoding from ISO-8859-1 to UTF-8. Fixed "make dist" script for dealing with Subversion instead of CVS. Added Speex to the README. Upped version to 1.0.2. 04112008 - Check if Speex header has bogus data (CVE-2008-1686). 08062007 - Updated my email address. 07152007 - Minor correction in Timidity resampling code (Thanks, Sam!). 07062007 - Fixed uninitialized buffer in mpglib. (Thanks, Phil!). 10292006 - Fixed bogus memory dereference when SMPEG fails init (thanks, Chris!) 10272006 - FLAC 1.1.3 breaks their API _again_, so we try to do the right thing at build time. (Thanks, Josh!). 05122006 - Patched to get mpglib compiling again (thanks, Sam!). 12172005 - Fixed gcc4 whining in playsound_simple.c. 12062005 - Trimmed a bunch of junk out of the build system, and now it works on Mac OS X again. 10122005 - Check for libmodplug headers in two possible places (thanks, Tyler!) 10012005 - Added playsound_simple.c. 05302005 - Backport from devtree: Fixed automake nonsense. 11122004 - Backport from devtree: fix .voc decoder crash on file open. 05082004 - Fixed "bootstrap" to work with MacOSX. 05072004 - Backed out some commits, converted repository to Subversion, and branched off to a 1.1.0 development tree. Changed MikMod URL...old one is now a porn site. :( 10252003 - VOC decoder was broken. Now it isn't. 10142003 - Build system fix: acinclude.m4 had some word wrapping badness. 10122003 - Fixed "make dist" behaviour to not packaged generated docs, and made sure other files are always packaged, regardless of config. Upped version to 1.0.1. 10102003 - Changed some SDL_Error()s to __Sound_SetError() in new DLS code to fix linking issues. 10052003 - Fixed memory corruption when freeing DLS instruments, and bug when timidity is initialized multiple times (Thanks, Sam!). 09252003 - Sam Lantinga added support for DLS instruments to the MIDI decoder. 09132003 - Happy September. Added Speex (.spx) decoder. 08052003 - Fixed MIDI decoder on bigendian systems. 03102003 - Never actually created samplelist_mutex (Thanks, Glenn Maynard!). 01302003 - Patches to make SDL_sound more Visual C happy (Thanks, Eric!). 01122003 - Fix to smpeg.c's rewinding code (Thanks, Eric). Put Visual C 6 project files in CVS, without external binaries (Thanks, Eric). 12212002 - Fixed ogg.c to decode a full buffer at a time instead of one ogg packet per call, and mikmod has a check during initialization to prevent a clash with SDL_mixer (Thanks, Eric). 12092002 - Changed Sound_Init()'s call to SDL_Init() to SDL_InitSubSystem(), to prevent unwanted use of the SDL parachute (thanks, Glenn). 10092002 - Fixed a "make dist" issue and upped version to 1.0.0! Woohoo! 09302002 - libFLAC broke their API (again!) for version 1.0.4. That was the last straw. I ripped the version detection and obsolete FLAC support out, so you need libFLAC 1.0.4 for that decoder now (and they'll probably break the API again for 1.0.5. Argh). 09262002 - Happy September. Fixed SDLCALL issues in SDL_sound.h, so it should work with Win32/WinCE builds again. I hope. Merged latest altcvt from Frank into CVS. 08222002 - Borland project files in CVS, thanks to Dominique Louis. There are project files for C++ Builder 6 (Windows), C++ Builder for Linux (aka Kylix 3) and Borland's C++ Command line compiler. 08172002 - Timidity memory leak cleanup by Torbjörn. 07292002 - Valgrind cleanups; memory leak patches, etc. 07212002 - done_flag was not being reset between files in playsound, so the first file would playback, and then any following tracks in a given run would "finish" immediately. Fixed. 07132002 - More altcvt fixes from Frank Ranostaj. 07122002 - Changed inline keyword to compile universally. 07102002 - Fixed a bug in command line handling in playsound.c. Fixes from Torbjörn and myself to get flac.c friendly between versions of libFLAC. Mutex'd a potential race condition in decoders/modplug.c. FIXME cleanups here and there. 07092002 - Fixed typo in documentation (SDL_sound.h). 07052002 - Cleaned up some stuff in playsound.c, removing some FIXMEs. Commandline validation is improved, too. FIXME removal in voc.c; should report i/o errors correctly now. Changed DECLSPEC to SNDDECLSPEC to prevent SDL conflict, and added SDLCALL support. Removed all instances of Sound_SetError()...now they are either __Sound_SetError or BAIL*_MACRO. 07022002 - Added WinCE support pack to website, updated INSTALL with CE info. More altcvt fixes from Frank Ranostaj. 07012002 - Fixed configure.in to work around bug in older autoconfs. Started merging Tyler's WinCE (PocketPC) port. Added checks for assert.h and signal.h to configure.in/config.h.in, and #if HAVE_*_H checks where appropriate in the code. Moved #include (along with the HAVE_ASSERT_H check) to SDL_sound_internal.h, and removed unnecessary #includes from the individual source files. Added "md_reverb = 1;" to MIKMOD_init(). Modplug got some WinCE-specific setting tweaks, and some settings maintanance code. configure.in checks if setbuf() is available. 06292002 - More altcvt fixes from Frank Ranostaj...mostly working now? 06252002 - More altcvt fixes from Frank Ranostaj. 06132002 - Patch from Torbjörn to fix stereo AIFF files. 06212002 - More altcvt fixes from Frank Ranostaj. 06132002 - Patch from Torbjörn to make the WAV decoder more tolerant. 06122002 - Committed some altcvt enhancements from Frank Ranostaj. 06112002 - Fixed some debug messages in smpeg.c and mpglib.c. 06072002 - Manpages! Finally installed Doxygen and scratched together a Doxyfile. After some revision to physfs.h, we've got a rather nice API reference. 06062002 - Added URLs for official and unofficial versions of ModPlug in decoders/modplug.c. Cleaned up some FIXMEs. 05222002 - Torbjörn sent in some more fixes for altcvt: mono to stereo conversion works, now. 05222002 - Torbjörn sent in some initial cleanups and fixes for altcvt, and fixed a bug in playsound when not all three of --rate, --channels and --format are specified. 05202002 - Some .cvsignores from Max and me. Added a seek implementations for the SMPEG, ogg, aiff, wav-adpcm, voc, and au decoders. Added a seek stub to quicktime.c. playsound now takes milliseconds in the seek lists: --seek "00:00:400" or whatnot. Corrected playsound's usage text. Other au.c cleanups for extra robustness. Added an experimental audio converter that Frank Ranostaj sent to the SDL mailing list about a month ago: enable it with --enable-altcvt at configure time, but be warned that it doesn't work very well right now. 04292002 - Darrell Walisser updated the Mac Classic and OS X project files, fixed some portability issues, and added an experimental decoder that uses Apple's QuickTime libraries (see decoders/quicktime.c). I've included the Mac project files in CVS, now. Removed all use of alloca() from playsound. 04242002 - Added --seek option and bugfixes to playsound.c. Torbjörn comes through with seek support for the FLAC, MIDI, and ModPlug decoders (and some stub code for MikMod), and a bugfix for sample flag manipulation in the base library (and his own --seek code for playsound, which unfortunately we're not using). 04232002 - Cleaned up the playsound command line handling. Most command line options (--rate, --format, --predecode, etc) are specified per-file and reset to their defaults after each sample is played back. --loop now takes a numeric argument: --loop 2 will playback the sample three times (one playback and two loops). Added Darrell to the playsound credits. 04212002 - Initial work to add a Sound_Seek() API. Removed the NEEDSEEK sample flag (replaced it with CANSEEK). Hack to change the internal Sound_SetError() function to __Sound_SetError(). Added internal function __Sound_convertMsToBytePos(). 04082002 - Cleaned up the archive support in playsound a little bit, and fixed a PhysicsFS bug in the process. 03252002 - Win32 patches and fixes from Tyler Montbriand: handled "inline" keyword, fixed SNDDBG macros in mpglib, and renamed a conflicting file (decoders/mpglib/common.c to decoders/mpglib/mpglib_common.c). 03172002 - Removed an unneeded #include in mpglib that broke build on BeOS. mpglib seems to work find on BeOS. Reworked some of mpglib.c so we can determine the audio format when accepting the data stream. Some other minor cleanups here and there. 03162002 - Tied the PhysicsFS code into the build system (code disabled if physfs not found or --disable-physfs passed to ./configure.) 03152002 - Added PhysicsFS support to playsound, so you can play sound files that are in ZIP files without unzipping them. Needs to be merged into build system (I was just testing my PhysFS->RWops glue code). 03142002 - Changed configure script's --enable-vorbis to --enable-ogg. Removed global state variable from mpglib, so it should be reentrant now (patches sent to mpglib's actual maintainer). playsound can now read from stdin. 03102002 - Added a FIXME note to decoders/mpglib.c. playsound now reports errors in the thread where they occured, which also fixes a double report of errors during predecoding. Removed all calls to exit() in mpglib. These calls now report errors correctly to SDL_sound, which passes them on to the application (patch also sent to mpglib's actual maintainer). Replaced all stderr chatter in mpglib with Sound_SetError() calls. 03072002 - decoders/mpglib.c now disregards ID3 tags instead of passing them on as valid MP3 data to mpglib. Added some (buggy) example code for adjusting an audio stream's volume (via the new --volume command line in playsound). 03032002 - Fixed mpglib's build configuration to include general build flags so that things like --enable-debug work as expected. 02212002 - Changed SMPEG's URL to point to the icculus.org site. Added an mpglib decoder (internal to SDL_sound; relies on no external libs) and changes mp3.c to smpeg.c (and other associated things). 02112002 - Committed a patch from Torbjörn to fix incorrect memory accesses in the Timidity code. Changed the magic number in the AU decoder to be bigendian (seems appropriate). Updated README for completeness, and TODO for accuracy. Darrell sent in updated MacOS X Project Builder files (on the website). 02072002 - Committed a patch Torbjörn sent in awhile ago for preventing confusion with Timidity++-specific stuff in the timidity.cfg file. Tyler Montbriand sent in an updated Visual C package. Updated SDL_sound.h's comments a little. Upped version to 0.1.5. 02052002 - Fixed a cleanup I broke last night. Added CWProject.sit to the EXTRA_DIST section of Makefile.am, and updated the README with MacOS (9/X) install instructions. 02042002 - Darrell Walisser submitted some cleanups and CodeWarrior project files for MacOS 9. Sweet! 01232002 - Max fixed decoders/Makefile.am to work with seperate build directories, and corrected some dates in this file. 01192002 - Torbjörn sent in patches implementing the rewind method for the rest of the decoders except shn.c, for which I added a kludged implementation. Added more info to the README. Hunted down the reason why SMPEG can't decode before calling SDL_OpenAudio(), and it can't be fixed without a change to SMPEG (not MY fault! :) ). Made ModPlug take priority over MikMod when selecting a decoder. Mutex-protected the internal samples list, and fixed some bugs in the management of that list. Changed some stuff to use uniform coding conventions. 01182002 - SDL_sound/playsound builds and runs on BeOS now. Fixed an assertion bug I introduced yesterday. 01172002 - Implemented Sound_Rewind(), and added a --loop command line to playsound for testing. Rewrote the audio callback to handle looping with both predecoded and streamed samples. Most of the decoders just have an assert(0) in their internal rewinding method at this point. I implemented the WAV, VOC, AU, AIFF, and RAW ones, for now. (...and skeleton.c, for what that's worth.) A few tweaks in the core API implementation to fix unlikely but possible leaks. 01112002 - Mattias Engdegård sent in an .AU decoder. Nice! He also tweaked playsound to try and wait until SDL has completed playing a given sound before closing the audio device. Changed a macro in decoders/shn.c to be more uniform with the other decoders. SDL_sound error messages are now maintained on a per-thread basis, and do not interfere with SDL_[GS]etError() anymore. 01112002 - Committed the rest of Torbjörn's MOD patches, to clean up file extension handling. 01092002 - Torbjörn comes through with a ModPlug-based decoder, which should work nicely for decoding multiple .MODs at once. Now we need to figure out what to do with two decoders that can decode the same file. For now, if you explicitly want either MikMod or ModPlug, you should explicitly enable one decoder and disable the other on the configure command line ("--enable-modplug --disable-mikmod", for example), otherwise configure will try to sort out the best one for your system. Choice is a wonderful thing. :) 01042002 - Forgot to bump playsound's version to match SDL_sound's. Fixed. Added some notes to the top of COPYING about other libraries, etc. A real MIDI decoder (using a hacked version of the hacked version of Timidity from SDL_mixer) is now in place and working well, thanks to Torbjörn. 01012002 - Happy New Year. Added some debug output to wav.c for future codecs (GSM comes to mind). Fixed the SMPEG decoder's URL to point to Loki's webpage. 12302001 - Upped version to 0.1.4. 12272001 - Added --audiobuf and --decodebuf options to playsound to make tracking down a bug in the ADPCM decoder easier (plus, it could help for benchmarking, etc later on...). Found a printf() bug in playsound (extra comma in there...). ADPCM decoder appears to be functional now. Tried to add ElectricFence support to configure.in, and failed. All this libtool/autoconf stuff makes my head hurt. 12262001 - Changed remaining references to the "LICENSE" file into "COPYING". Work progresses on the ADPCM-compressed .wav decoder. Updates to the documentation in SDL_sound.h. Hhmm...find_chunk() in wav.c was badly broken. Fixed. 12162001 - FLAC decoder now checks for the magic number unless the file extension is recognized. This was changed back because searching for metadata, while probably more effective, is VERY expensive (and useless) on non-FLAC streams. 12052001 - Put our names in a "--credits" option in playsound, and put the standard GNU disclaimers in there too, for good measure. Renamed LICENSE to COPYING to match GNU standards more closely (and to end Max's torment. :) ) Tweaks to wav.c, and work on aiff.c to make it easier to support multiple audio formats (for compression handling later down the road). 11302001 - Torbjörn and I make Sound_DecodeAll() more robust: checks for previous decoding failures and sets an appropriate error, handles decoders that change their buffers on the fly (such as the FLAC decoder), and deals with out-of-memory conditions more gracefully. 11252001 - (With thanks to Andreas Umbach for pointing it out) Fixed some problems with Sound_DecodeAll(). For local testing of this bug, added a --predecode command line to playsound. Minor fixes to theoretical bugs in Sound_FreeSample(). playsound no longer buffers stdout and stderr. Updated Sound_DecodeAll()'s comments in SDL_sound.h ... 11192001 - FLAC decoder cleanups from Torbjörn. 11092001 - Torbjörn fixes playsound's audio callback after I broke it, again. A bug in configure.in was preventing SMPEG from being used unless --enable-debug was set; fixed. Changed this file to list latest changes first. Torbjörn submitted a FLAC decoder that utilizes libFLAC (http://flac.sf.net/). Cool. 11012001 - API COMPATIBILITY BREAKAGE: Decoders can now list multiple file extensions each. Playsound has been updated to handle this. Playsound now registers a SIGINT handler, so you can skip tracks and/or abort the way that mpg123 does. 10232001 - Rewrote playsound.c's audio_callback() to no longer need the overflow buffer hack, which streamlines it a little and trims the memory requirements for playsound by about 16 kilobytes. 10172001 - Torbjörn catches a problem with the overflow buffer in playsound's audio callback. 10152001 - Torbjörn sends in a default sample format for the MIDI decoder, and the starts of the audio conversion funcitonality (ripped from SDL). Officially released 0.1.3. Added LICENSE and CHANGELOG to the distribution. (Again, from Torbjörn) added in the start of a tweaked audio converter. 10122001 - Torbjörn Andersson submitted command line enhancements to playsound, and I cleaned up the --help output. 10092001 - Patches to shn.c for Visual C compatibility. Visual C project files available from the website. Changed Corona688 to Tyler Montbriand in CREDITS. Upped version to 0.1.3. 10082001 - Restructured decoders/wav.c to allow for multiple formats, and put the start of a handler for the ADPCM format in place. 10072001 - Changed the way decoders/mod.c handles samplerate so that it should work universally. This isn't an ideal solution, but it's probably the best we can do without rewriting mikmod. Made a change to ogg.c for portability: changed an int64_t to ogg_int64_t. 10062001 - Made a change to SDL_sound.c for compiling on non-GNU toolchains. 10052001 - Removed #include "SDL_endian" from aiff.c. 10042001 - Changed some #if (defined SOUND_SUPPORTS_*) lines to #ifdef SOUND_SUPPORTS_* in voc.c and shn.c, for consistency with the other decoders. 10032001 - After hours of tracking down a bogus pointer, the SHN decoder works! I can die happy. :) Max placated me with an --enable-debug option so I could stop my whining. Other autoconf goodies (such as reenabling -Werror for debug builds, etc). Torbjörn brings in a MIDI decoder, which reads from a Timidity process through a pipe. Changed playsound to open the audio device to match the properties of each sound file, which results in less conversion (and therefore, more chance of correct playback). 10022001 - Changed a comment in mod.c to not refer to "the mikmod directory" anymore. Committed Torbjörn's patch for MP3 detection. (better late than never). __Sound_strcasecmp() now handles NULL strings gracefully, fixing the crash with "playsound bootstrap". More work on the SHN decoder. 10012001 - Fixed a memory leak that Torbjörn found in the MOD decoder. 09252001 - More autoconf work. Gave Max Horn write access to the CVS repository, so I don't drive him nuts tweaking this thing. :) Fixed a const complaint and some other stuff needed for compilation under Visual C++ 6.0 (no, it isn't ported yet). Put the SHN source in CVS, even though it isn't ready (and doesn't even compile). Do NOT enable it in your build! 09242001 - Thank goodness, Torbjörn came through with the MP3 fix. Apparently SMPEG mixes each chunk of decoded data with whatever is already in the buffer you give it. I hate that. I'm going to patch SMPEG to let the programmer enable and disable that behaviour in a given (SMPEG *), since it's just a CPU eater in this case. The _D(()) macro is now SNDDBG(()), since _D is taken on MacOS X's version of gcc (which was bound to happen on some platform sooner than later anyhow). Renamed test_sdlsound to playsound, and made it more robust in general: fixed potential overflow in audio_callback, made it chatter less, made it take multiple files and some other command lines. Initial autoconf support, thanks to Max Horn. 09222001 - Torbjörn Andersson strikes again, with a collection of patches. First, some cosmetic tweaks for decoders/aiff.c. Next, a MOD player based on MikMod. This inspired me to add two more methods to Sound_DecoderFunctions: init() and quit(). Third, a fix to decoders/mp3.c so that SMPEG won't claim every stream it sees, MP3 or not. I removed the multiple-streams-per-rwops code, after discussion on the mailing list. The init() and quit() methods led to the possibility that certain decoders will flag themselves as unavailable at runtime, and SDL_sound now handles this. Added [LIB|INC]PATH_[OGG|MOD]. Bigendian fixes; now works on PowerPC Linux. MikMod tweaks. Changed version to 0.1.2. 09202001 - Torbjörn Andersson submitted several patches: fixed a comment in the .WAV decoder (whoops...screwed up my own search-and-replace. Hah.), made an attempt at putting multiple sound streams behind one RWops (gotta think on that one first), and, most importantly, added an AIFF decoder, which is very cool. 09192001 - Added a skeleton decoder source file. Changed voc_read() to voc_read_waveform(), so it wouldn't be confused with VOC_read(). Fixed a byte ordering bug in voc.c (reported as AUDIO_S16LSB, but we were swapping byte order of data ourselves. Fixed). Added basic .WAV support. Fixed Makefile so that -I. is always first; otherwise, a previously installed header might get used for the compiles, which is not good. SDL_sound.h now includes SDL_endian.h, since SDL.h doesn't, for some reason. Moved version defines in SDL_sound.h to top of file so I can find them. :) Changed version to 0.1.1. Committed patch from Tsuyoshi Iguchi to fix a segfault (I forgot to put a NULL terminator at the end of the available_decoders array), fixing the only bug preventing the test program from running on FreeBSD 4.3. Sweet. Added Ogg Vorbis decoder. Rewrote the test program's SDL audio callback to be more robust (Ogg exposed a nasty bug in it). Fixed a byte-ordering issue in the VOC decoder. 09182001 - Implemented MP3 support through SMPEG (not working yet, though) and wrote the Reference Counting RWops wrapper. Added other little things like the _D(()) macro. Added VOC support, which went up with surprisingly little struggle, which means it MUST be leaking memory. :) 09172001 - Changed some overlooked "voice" to "sound". Implemented base API. So...tired. Everything's different. :) Also put in a RAW decoder and a simple test program. 09142001 - Changed name to SDL_sound, added Sound_DecodeAll() to spec. 09132001 - Initial spec proposed on SDL mailing list, under name "SDL_voice". --ryan.

It is based off the code in the CVS after the 1.0.0 release (1.0.1?). This project has options to build a DLL or static library and build playsound (dynamic or static). This project mimics the original pre-1.0.0 version which no longer works with the current code. Unlike the former package, this one contains no binaries. This will allow this project to be included in the main SDL_sound source code. You will be responsible for finding the binaries you need for each decoder. We have attempted to provide a Support pack which contains the binaries built and tested with. However, many of the binaries become quickly outdated so you may not want to depend too heavily on the Support pack. If you need the binaries, you should either copy the files to your default VisualC++ directories (both headers and libraries), or add them to your search paths, either through the Project Settings for Include and Link paths or through the global settings (Tools->Options->Directories in VC6). You need to do it both for the header files (includes) and library files. To run your final executables, you will need the DLL files in the local path or one of your Windows main DLL search paths. Issues: The static playsound really isn't static. You still need the dlls for each of the codecs. You will have to tweak the project to build a true static binary and will probably require you to have static versions of all the decoder libraries.

I'm hereby extending the TiMidity license agreement: you can now select the most convenient license for your needs from (1) the GNU GPL, (2) the GNU LGPL, or (3) the Perl Artistic License. -------------------------------------------------------------------------- This is the README file for TiMidity v0.2i TiMidity is a MIDI to WAVE converter that uses Gravis Ultrasound(*)-compatible patch files to generate digital audio data from General MIDI files. The audio data can be played through any sound device or stored on disk. On a fast machine, music can be played in real time. TiMidity runs under Linux, FreeBSD, HP-UX, SunOS, and Win32, and porting to other systems with gcc should be easy. TiMidity Features: * 32 or more dynamically allocated fully independent voices * Compatibility with GUS patch files * Output to 16- or 8-bit PCM or uLaw audio device, file, or stdout at any sampling rate * Optional interactive mode with real-time status display under ncurses and SLang terminal control libraries. Also a user friendly motif interface since version 0.2h * Support for transparent loading of compressed MIDI files and patch files * Support for the following MIDI events: - Program change - Key pressure - Channel main volume - Tempo - Panning - Damper pedal (Sustain) - Pitch wheel - Pitch wheel sensitivity - Change drum set * The GNU General Public License can, as always, be found in the file "../COPYING". * TiMidity requires sampled instruments (patches) to play MIDI files. You should get the file "timidity-lib-0.1.tar.gz" and unpack it in the same directory where you unpacked the source code archive. You'll want more patches later -- read the file "FAQ" for pointers. * Timidity is no longer supported, but can be found by searching the web.

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it!

I've removed one particularly annoying one, but... Some of them should be turned into error messages instead. * Can the instrument handling be made more efficient? At the moment different MidiSongs may separately load the same instrument. Note that the MidiSong's audio format affects how the instrument is loaded, so it's not as easy as just letting all MidiSongs share tone and drum banks. At the moment they do share the data that is simply read from the config file, but that's just a quick hack to avoid having to read the config file every time a MIDI song is loaded. * Check if any of MidiStruct's members can safely be made into static globals again. * TiMidity++ adds a number of undocumented (?) extensions to the configuration syntax. These are not implemented here. In particular, the "map" keyword used by the "eawpats". * The other decoders generally only read as much of the file as is necessary. Could we do that in this decoder as well? (Currently it seems to convert the entire file into MIDI events first.) * Can it be optimized?

In addition, I've made some changes of my own, e.g.: * All file access is done through SDL_RWops. This means the MIDI stream no longer has to be a file. (The config file and instruments still have to be though.) * Replacing of TiMidity's endian-handling with SDL's. * Removal of much unused or unnecessary code, such as + The "hooks" for putting a user interface onto TiMidity. + The antialias filter. It wasn't active, and even at 4 kHz I couldn't hear any difference when activating it. + Removed all traces of LOOKUP_HACK and LOOKUP_INTERPOLATION. According to the code comments they weren't very good anyway. ("degrades sound quality noticeably"). I also removed the disclaimer about the "8-bit uLaw to 16-bit PCM and the 13-bit-PCM to 8-bit uLaw tables" disclaimer, since I believe those were the tables I removed. + Removed LOOKUP_SINE since it was already commented out. I think we can count on our target audience having math co-processors nowadays. + Removed USE_LDEXP since it wasn't being used and "it doesn't make much of a difference either way". + Removed decompress hack from open_file() since it didn't look very portable. + Removed heaps of unnecessary constants. + Removed unused functions. + Assume that LINEAR_INTERPOLATION is always used, so remove all code dealing with it not being so. It's not that I think the difference in audio quality is that great, but since it wouldn't compile without code changes I assume no one's used it for quite some time... + Assume PRECALC_LOOPS is always defined. Judging by the comments it may not make much of a difference either way, so why maintain two versions of the same code? * Moving several static globals into the MidiSong struct. This includes sample rate, formate, etc. which are now all per-song. * Moved some typedefs (e.g. MidiSong) to timidity.h for easy inclusion into the MIDI decoder. * Added free_pathlist(). * Replaced TiMidity's own 8, 16 and 32-bit types with SDL's. * Made TiMidity look for its configuration file in both /etc and /usr/local/lib/timidity. (Windows version remains unchanged.) * Timidity_PlaySome() now takes three arguments. A MidiSong, a decode buffer and decode buffer size in bytes. (MidiSong is a new argument, and buffer size used to be in samples.) In addition, it will return the number of bytes decoded. * Added Timidity_Exit(). * Removed Timidity_Stop() and Timidity_Active(). Stopping playback should be handled by SDL_sound, and Timidity_PlaySome() will return 0 when the MIDI stream is finished. * Modified the ToneBank stuff to allow some data to be shared between MidiSongs. * The following files have been removed: controls.c, controls.h, filter.c, filter.h, sdl_a.c, sdl_c.c * config.h has been renamed as options.h to avoid confusion with the automatically generated config.h for SDL_sound. * Added support for loading DLS format instruments: Timidity_LoadDLS(), Timidity_FreeDLS(), Timidity_LoadDLSSong() * Added Timidity_Init_NoConfig() SDL_sound-1.0.3/decoders/timidity/FAQ0000644000175000017500000001126511001707504014244 00000000000000---------------------------*-indented-text-*------------------------------ TiMidity -- Experimental MIDI to WAVE converter Copyright (C) 1995 Tuukka Toivonen -------------------------------------------------------------------------- Frequently Asked Questions with answers: -------------------------------------------------------------------------- Q: What is it? A: Where? Well Chris, TiMidity is a software-only synthesizer, MIDI renderer, MIDI to WAVE converter, realtime MIDI player for UNIX machines, even (I've heard) a Netscape helper application. It takes a MIDI file and writes a WAVE or raw PCM data or plays it on your digital audio device. It sounds much more realistic than FM synthesis, but you need a ~100Mhz processor to listen to 32kHz stereo music in the background while you work. 11kHz mono can be played on a low-end 486, and, to some, it still sounds better than FM. -------------------------------------------------------------------------- Q: I don't have a GUS, can I use TiMidity? A: Yes. That's the point. You don't need a Gravis Ultrasound to use TiMidity, you just need GUS-compatible patches, which are freely available on the Internet. See below for pointers. -------------------------------------------------------------------------- Q: I have a GUS, can I use TiMidity? A: The DOS port doesn't have GUS support, and TiMidity won't be taking advantage of the board's internal synthesizer under other operating systems either. So it kind of defeats the purpose. But you can use it. -------------------------------------------------------------------------- Q: I tried playing a MIDI file I got off the Net but all I got was a dozen warnings saying "No instrument mapped to tone bank 0, program xx - this instrument will not be heard". What's wrong? A: The General MIDI standard specifies 128 melodic instruments and some sixty percussion sounds. If you wish to play arbitrary General MIDI files, you'll need to get more patch files. There's a program called Midia for SGI's, which also plays MIDI files and has a lot more bells and whistles than TiMidity. It uses GUS-compatible patches, too -- so you can get the 8 MB set at ftp://archive.cs.umbc.edu/pub/midia for pretty good GM compatibility. There are also many excellent patches on the Ultrasound FTP sites. I can recommend Dustin McCartney's collections gsdrum*.zip and wow*.zip in the "[.../]sound/patches/files" directory. The huge ProPats series (pp3-*.zip) contains good patches as well. General MIDI files can also be found on these sites.

A: Find out which patch is responsible for the clicking (try "timidity -P ". Add "strip=tail" in the config file after its name. If this doesn't fix it, mail me the patch. -------------------------------------------------------------------------- Q: I'm playing Fantasie Impromptu in the background. When I run Netscape, the sound gets choppy and it takes ten minutes to load. What can I do? A: Here are some things to try: - Use a lower sampling rate. - Use mono output. This can improve performance by 10-30%. (Using 8-bit instead of 16-bit output makes no difference.) - Use a smaller number of simultaneous voices. - Make sure you compiled with FAST_DECAY enabled in options.h - Recompile with an Intel-optimized gcc for a 5-15% performance increase. -------------------------------------------------------------------------- SDL_sound-1.0.3/decoders/timidity/Makefile.testmidi0000644000175000017500000000227711001707504017176 00000000000000# Silly test makefile CC = gcc # Standard SDL_sound debugging CFLAGS = -g -I../.. -ansi -pedantic -Wall `sdl-config --cflags` -DDEBUG_CHATTER LIBS = `sdl-config --libs` # Electric Fence debugging # CFLAGS = -g -I../.. -ansi -pedantic -Wall `sdl-config --cflags` # LIBS = `sdl-config --libs` -lefence OBJECTS = common.o instrum.o mix.o output.o playmidi.o readmidi.o resample.o \ tables.o timidity.o testmidi.o all: testmidi testmidi: $(OBJECTS) $(CC) $(OBJECTS) $(CFLAGS) -o testmidi $(LIBS) clean: $(RM) testmidi *.o *~ common.o: common.c options.h common.h instrum.o: instrum.c timidity.h options.h common.h instrum.h resample.h \ tables.h mix.o: mix.c timidity.h options.h instrum.h playmidi.h output.h tables.h \ resample.h mix.h output.o: output.c options.h output.h playmidi.o: playmidi.c timidity.h options.h instrum.h playmidi.h output.h \ mix.h tables.h readmidi.o: readmidi.c timidity.h common.h instrum.h playmidi.h resample.o: resample.c timidity.h options.h common.h instrum.h playmidi.h \ tables.h resample.h tables.o: tables.c tables.h testmidi.o: testmidi.c common.h timidity.h timidity.o: timidity.c options.h common.h instrum.h playmidi.h readmidi.h \ output.h timidity.h tables.h SDL_sound-1.0.3/decoders/timidity/testmidi.c0000644000175000017500000000472511001707504015703 00000000000000/* * SDL_sound -- An abstract sound format decoding API. * Copyright (C) 2001 Ryan C.
