A lot of audio programs, such as Audacity, support encoding files as AIFF (Audio Interchange File Format, developed by Apple Inc.).
However, I need specifically an AIFF file that has been compressed with ima4, making it an AIFC file.
The internet seems to be nearly clueless about AIFC and ima4. "convert to AIFC" (with quotes) yields exactly 0 results on Google (3M for MP3, 90K for WAV, 45K for FLAC, ...).
- ffmpeg. I know
ffmpeg -i wavefile.wav -f aiff wavefile.aiffconverts to AIFF but I can't figure out how to specify the compression algorithm.
- afconvert. According to here, we can use
afconvert -f AIFC -d ima4 [file]. But this is a Mac-only program and I only have access to Windows and Linux Mint machines.
- afftools. See here. This strangely seems to be a Fedora-only program, and I once again can't find anything on it on Google (if it even does what I want).
- Adobe Audition. See here. Once again I do not own this paid-for software.
