Check out Übercaster… this looks like a major improvement for Mac podcast producers. I’ve never been terribly impressed with Garageband as a production tool, and have pretty much stuck with Audacity since I can keep my brain on one track, whether working in Windows or Mac. Übercaster might get me to shift as soon as I upgrade my Powerbook G4 to OS X Tiger. (yeah, I know… it’s been out forever and is about to be supplanted. Yadda yadda yadda…).
Prices go up in a couple of weeks… I’ll see what I can do about reviewing it sometime before that happens.
