I didn't think an AIFF-C file could contain little-endian data, any more than an AIFF file can. How on earth is this indicated? An AIFF-C file, like AIFF, starts with the 4-byte tag <FORM>, followed by a 4-byte chunksize, followed then by the tag <AIFC> - and the FORM chunksize must surely be big-endian in all cases, as that is what is expected. It would seem to be impossible to define an AIFF-C file to be either little or big-endian, to begin with!


My document describing AIFF-C is admittedly somewhat elderly (vintage 1991); but I haven't seen one anywhere that is newer. That document expressly describes all data as big-endian, everywhere. Any pointers to more up to date specifications would be most welcome.

They are AIFC files - AIFF cannot legally contain either little endian or float data


Yeah i knew and even checked those files were AIFC...

I would hope that the AudioFile changes in 10.2.3 would correctly describe these as AIFC files as little-endian based files


Well i guess i should check the version of my Frameworks then.
