I am trying to use Cocoa to capture, or at least have audio data placed live
into a buffer, where I can analyse it. I wrote some software for OS7 / 8
which used a SoundManager call that returned the current volume being played
into the current audio input. This was adequate at the time, as it was
enough to vary some simple graphics in time with incoming music, or music
being played on a CD.
Can anyone advise an easy way to get hold of sound data as it is being
played via iTunes, and / or sound data as it is being played into the
default input? I think I may have the second option covered using
MTCoreAudio, and a recording sound input example on this page:

I realise this may sound trivial, but I've been trying to work out how to do
this for a while now - reading the CoreAudio documentation, and getting
nowhere fast.
Many thanks
Stephen Wolff
