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
