Best new app of 2006: Right now my leading contender is Fission. I'm constantly having to cut and snip audio, and Fission gives me exactly what I need without sapping the heck out of my laptop, even the older ones. And once I'm finished editing, I can just save the file without having to recompress it. Very nice, especially for MP3s, because there's no quality loss. Amazing how much I can do with Fission, Audio Hijack Pro, QuickTime Pro, and GarageBand if I need it.
