Audio File Library

Audio File Library Version 0.3.6 Wednesday, 6 March 2013 Copyright (C) 1998-2000, 2003-2004, 2010-2013 Michael Pruett Copyright (C) 2000-2001 Silicon Graphics, Inc. michael@68k.org http://audiofile.68k.org/ ---- The Audio File Library handles reading and writing audio files in many common formats. Key goals of the Audio File Library are file format transparency and data format transparency. The same calls for opening a file, accessing and manipulating audio metadata (e.g. sample rate, sample format, textual information, MIDI parameters), and reading and writing sample data will work with any supported audio file format. Likewise, the format of the audio data presented to the application need not be tied to the format of the data contained in the file. The following file formats are currently supported: * AIFF/AIFF-C * WAVE * NeXT .snd/Sun .au * Berkeley/IRCAM/CARL Sound File * Audio Visual Research * Amiga IFF/8SVX * Sample Vision * Creative Voice File * NIST SPHERE * Core Audio Format * FLAC The following compression formats are currently supported: * G.711 mu-law and A-law * IMA ADPCM * Microsoft ADPCM * FLAC * Apple Lossless Audio Codec The Audio File Library itself is available under the GNU Lesser General Public License, and the programs in this package are available under the GNU General Public License.

I decided to port it under OS/2 because I needed it to complete my OS/2 FUSE (ZX Spectrum Emulator) port on OS/2, in order to make it as flexible as possible. *-*-*-*-*-*-*-*-*-*-*-*- Some notes *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- This time it wasn't a simple configure/make/make install round! First of all I had to tweak some code in order to enable make recognizing the __GNU_PREREQ macros defined in features.h, since there already is a "features.h" include file in the source tree. This made it impossible to recognize the macro, so I added it into this file under an ifdef __OS2__ condition. Second: audiofile uses a mixed .C / .CPP source tree, and I found (weird) that this created some problems with my GCC 9.2.0 install under ArcaOS. No problems compiling, but the C++ files needed to be linked against libstdc++ explicitly. After some fiddling with the makefiles I was able to build a complete library, together with a sample file format converter (sfconvert.exe). Third: some of the accompaining software was to be completely linked with libstdc++, even if there was some C code! Luckily, make pointed me to the specific errors. Lastly: documentation is written in DocBook format, so I installed AsciiDoc and modified the makefiles again. Everything worked perfect and I was finally able to create this binary tree. Hope this will be useful to other fellows developers.
