Hi Chris,

Have you checked out this list?
http://www.lists.apple.com/mailman/listinfo/pro-apps-dev

Apple folks there might be able to answer some questions?

Hope that helps,

Robert.

the apps I'm developing, I was hoping this would be more readily available...

[AMENDED REPOST:]

Is the spec for the AIFF/AIFC format as currently implemented by
Apple apps publicly available (free or for a fee)?

I've seen this question posted before but haven't seen a
definitive answer or URL.

In looking at AIFF files provided with Soundtrack I'm seeing things
that aren't mentioned in either the old (sgi.com) AIFC spec found online,
in the original AIFF draft spec from Apple, or in the QuickTime /
Sound Manager documentation. In particular there are chunks like
'basc', 'trns', 'cate', and 'JUNK'. If these are application-specific things
I'd expect them to be buried in an 'APPL' chunk, but they're not.

I've also seen a few places online where "undocumented extensions"
to AIFF are mentioned, which don't utilize the 'APPL' chunk.

I'd like to maximize interoperability with Soundtrack and other apps
that make extended use of AIFF/AIFC.

Thanks,
Chris
