"Easy" and "CoreAudio" can't be used in the same sentence. :P
CoreAudio is very powerful, very complex, and under-documented. Be
prepared for a steep learning curve, APIs with millions of tiny
little pieces, and puzzling things out from sample code rather than
reading high-level documentation.
I'm stuck at the very beginning of the process: open the audio files
and make my audio buffers.
/Developer/Examples/CoreAudio is where all the good stuff is. Look
at SimpleSDK/PlayFile, which creates a simple AUGraph to play audio
from a file. (However, I'm unsure of whether all this stuff, like
AUGraph, is available on iPhone...)
For just reading samples from arbitrary audio files, the API you
want is <AudioToolbox/ExtAudioFile.h>. There are several examples
that show how to use it, such as ConvertFile.
