Actually...

The real recommendation is that as AIFC is still limited in the types of audio compression formats it can contain, we now strongly encourage and recommend developers to use the CAF file format as a complete superset of both AIF and WAV files.

Details on CAF can be found at Apple's developer web site - there is a full specification document.

CAF is also supported in the OS from Tiger onwards



A propos of which - can you say how widely CAF is supported by Windows
apps?  There is some support in libsndfile, but I am not sure how
comprehensively. It will be a while before AIFC (and WAVE for that
matter) cease to be primary audio file formats. And I note that  Space
Designer impulse response files are essentially just AIFF files with an
SDIR extension. Which is reasonable enough - they will always be
relatively short files. If anything, AIFF and AIFC are becoming less
relevant simply because on an Intel Mac they are not the native endianness.
