Actually, I had known that part :) But the problem is specifically
with Core Audio because I cannot see how to get amplitude information
from an AudioQueue during recording.
Let me put it a different way. I can see how to do it all on playback.
I just can't see how to do it during recording. The properties are
different and I'm not seeing anything to help there.

HI Alex,
Fourier Analysis is what you should start with to understand the
basics.
Then you might want to look into: Discrete Fourier Transform, and
more specifically the Fast Fourier Transfer which will allow you to
analyse the frequency content of your recording. According to the
wieght of each frequency component in your signal you will be able
to display the signal in the frrequency domain.
hope that helps,
Charles
