Question, guys. I have recently jumped the bandwagon and started a podcast with a friend. So far we are just using the bulit-in mic on my powerbook, but I am looking to expand this set-up. We are both poor college students, so right now I want to keep things as cheap as possible, so buying a mixer for two mics is something I'd rather avoid right now. I was wondering: if I could find two usb mic headsets cheap, could I connect both of these and use a software mixer? That is to say, would the mac see both usb inputs as two sepreate audio streams and allow the mixer to use them? Thanks!
