Detailed Description
AudioFileReader uses the Audio File Library ( http://www.68k.org/~michael/audiofile/ ) to read sound data.
It supports AIFF/AIFF-C, WAVE, NeXT/Sun .snd/.au, Berkeley/IRCAM/CARL Sound File, Audio Visual Research, Amiga IFF/8SVX, and NIST SPHERE. Supported compression formats are currently G.711 mu-law and A-law and IMA and MS ADPCM.
