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/

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.
