I expect I could do it as part of my work on Ogg Frog:

In the short term, I would do it by accessing the QuickTime APIs -
which *are* available on Windows, if you install either iTunes or
QuickTime for Windows.  (The iTunes install includes QuickTime.)

In the long term, I could write a codec for it that would be
straightforward to integrate into the flac command-line tool.  That
would allow its use on UNIX.

HOWEVER!

Is the CoreAudio file format or its associated algorithms patented?
QuickTime in general has many patents.

A patent wouldn't stop me from writing the source code, but a binary
couldn't be provided by anyone in a country that recognizes software
patents.
