The problem occurs when encoding to AAC or Apple Lossless, with a

I see what you mean here, sadly I can't tell you why your seeing what your seeing. As a work around would it be possible to record to and work with CAF instead of M4A?


So it seems there might  be a problem with kAudioFileM4AType, where
the data is not being flushed to disk but is instead staying in
memory.

It'd have to be a CoreAudio guy that looks into this one... -- Reality is what, when you stop believing in it, doesn't go away. Failure is not an option. It is a privilege reserved for those who try.
