Hi Oliver,
So where do I look next?
if you want to use CoreAudio and MTCoreAudio, the recordotron example might be interesting for you:
http://borkware.com/rants/sound/
More precisely I came across a thread on the coreaudio-api mailing list: "Newbie: trying to log samples", which handles this exact topic. Starting here:
http://lists.apple.com/archives/coreaudio-api/2005/Feb/msg00016.html
so maybe this might not the best list to ask ;-)

First, I want to say that it's really a major pain to record sound in
Cocoa. Really. Anyway, I can sucessfully record from the sound input
to AIFF... which is an important part of my app.
But when recording, I think the user should have a visual feedback of
the input's amplitude (e.g. sound meters...)

I've carefully inspected MTCoreAudio too -- found nothing that could have
helped me.
