I was able to verify an audio CD, what I want to do now is calculate the RMS value of the whole CD (http://en.wikipedia.org/ wiki/Root_mean_square), I'd like to know how I can just extract only the audio samples from a CD, which will be from different .aiff files. Does anyone maybe have some more info on how to do this?

You can use the Extended Audio APIs to extract audio from the files that are exported as the contents of the CD. There should be an example in /Developer/Examples/CoreAudio that should show you how to do so. I don't know the best example off hand, but I'm certain someone else can point it out.

Failure is not an option. It is a privilege reserved for those who try.
