I need to analyze MP3 and AAC content in order to determine BPM . . .

I know there are other programs out there that do this but I want to integrate this functionality directly into my application.

Where do I begin?  Do I need to create an audio unit?

I'm happy to accept any advice, pointers, or sample code.

Thanks for any help you can offer.

BTW: I'm also looking for sample code or documentation on accessing iTunes metadata, for obvious reasons. I have Apple's spec but am having difficulty understanding it. It is a bit abstract and lacks context. I suppose I'll have to go back and read the related ISO docs to understand it.
