The AudioFile code will currently only deal with non-compressed data
reliably and AIF/WAVE/SD2 should all work the same. We are doing some
more work in this area that we'll be going over in some detail at WWDC
We did fix the bug in 10.2.5 for the CD files (it was a mismatch on the
resource if I remember correctly).

Matt,
Something is wrong with either the audio files you are using or your
use of the AudioFile API. AIFF and WAV files work just fine with all
other software I've seen using the AudioFile calls (including my own).
There were some reports of a bug with AudioFile and aifc files in CD
audio format (can't remember which endian that is, little?), though.
But what's weird is that as far as I knew (And John, that's why he
asked I would guess), mp3 files are *not* supported. Nor is any other
compressed format.
So.. what OS version are you using? 10.2.5?
CA team: was support for mp3 and/or other compressed audio formats
added to the AudioFile API?
Guess it's time to do some experimenting... :)

Hey Matt, the AudioFile API works with MP3? Does it do the
decompression itself?
it returns a buffer in 'mp3 ' stream format - maybe you can pass it
through an AudioConverter routine?- but i haven't tried --- im more
interested in aiff and wav file support at the moment - but for those
formats, kAudioFilePropertyDataFormat returns an empty stream
description and AudioFileReadPackets() does not return any frames.
AudioFileReadBytes() appears to work, but all the header info is
in there - so its not much use...
