Hi Bill,
Thanks for the reply! I don't really understand how AAC exists in mpeg2
and mpeg4, since I thought AAC was mpeg4 based, not that it matters any
since I really know nothing.
What I'd really like to know is the details in filling out the
AudioStreamBasicDescription for the AudioConverter AAC type...
Thanks!

The AudioFile API supports the ADTS file - this is an MPEG2 defined
bit stream, but it is not MPEG-4.
QT can make mp4 files, and the iTune's m4a files are essentially
MPEG-4 files that have just audio data in them.
At this stage there's no direct bridge between these two bit streams,
but this will be addressed at some point
Bill
