Don't think we've ever tried it, to be honest ... so the short answer
is that it's officially unsupported ... though we can try to help here

The first of many errors chimes in with the compiler complaining:
"CAAudioChannelLayout.h:66: error: parse error before `&' token"
where that line of code reads:
"bool operator== (const AudioChannelLayout &x, const
AudioChannelLayout &y);"
AudioChannelLayout is not defined in the Jaguar CoreAudioTypes.h.
That could be solved by updating to a newer SDK.
Here's hoping that's not the case, but it would be good to know. The
'ReadMe.rtf' file doesn't say so, but it looks like XCode is not happy
when I set the project target from 10.3 to 10.2.8.
So in the area of channel layouts there is definitely a Panther
dependency, though that might be avoidable if you don't exercise any
code involving channel layouts. The crux of the matter is how whether
the 10.2 implementations of AudioConverter and AudioFile support the
way that CAAudioFile and related classes use them. I suspect things may
work if you don't use any compressed formats, but that's just a hunch.
