More projects to check out

• SoX is a program for converting between sound file formats.
• Wavplay started out as a minimal WAV file player under Linux and has mutated into Gnuwave, a client/server application for more general multimedia and games sound playback.
• Audiofile (libaudiofile) is a library similar to libsndfile but with a different programming interface. The author Michael Pruett has set out to clone (and fix some bugs in) the libaudiofile library which ships with SGI's IRIX OS.
• sndlib is another library written by Bill Schottstaedt of CCRMA.
