copy media files from iPod library to an app

I am thinking about app which should play audio files placed in iPod library and played by Audio Units to make sure that IO has the lowest possible latency. As I know I cannot use standard way because direct iPod library playing is supported only within AVFoundation.

So my question is, if there is any开发者_如何转开发 possible way to copy picked media files into an app and then play them by audio units.

I’ve written some sample code that does this: https://github.com/davidcairns/MediaPlayerDemo

Try this:
