What is an AIFC file?

AIFC – AIFF-C compressed audio. AIFC (AIFF-C) is AIFF that may be compressed or have its samples in the other byte order; older Macs and some editing programs use it. Converting makes a new file: the sound is decoded and written again, so converting from a lossy format never brings back what was lost.
