Hi Austin,

If you check out Kurt Revis' PlayBufferedSoundFile at his website www.snoize.com, that might help.

For my project I must be able to play encrypted AAC files through an AUGraph. Hopefully inline decryption is in the development pipeline for AudioFile, but in the meantime there must be a way to channel audio from QuickTime into the CoreAudio layer. I don't know what to do, and it seems that I am not the only one with the same problem.

So I think the relevant question for the moment is: How do I redirect the uncompressed audio stream leaving a playing QT movie into some other buffer (in this case CoreAudio). I remember hearing that all parts of the QT pipeline are modular, so there must be some way to do this.

Details that we can act upon would be greatly appreciated by me and everyone else who wants to be able to program with purchased music.

- Austin
