Very elegant, straightforward audio editing app. Similar in functionality to Audacity (which is free) but for the dollars you spend you get a much nicer looking and more intuitive interface and some neat features that Audacity lacks. I use Sound Studio for nearly all my audio editing work, which includes working with classical music as well as editing podcasts – very pleased with its performance. If you're looking for nondestructive editing this won't do, but otherwise I'd highly recommend it.
