About the AIFC format

AIFF-C (AIFC) extends AIFF so the audio can be compressed, for example with IMA ADPCM, μ-law or Apple's MACE codecs, or stored as floating-point samples. Classic Mac OS used it for system sounds and some games.

Few current players handle every AIFC codec. FFmpeg reads them, so AIFC files can be converted to WAV, MP3 or FLAC.
