It has some truly killer noise removal tools.
I love being able to look at a wave in spectral view, highlight a specific sound in a very specific freq range, and then remove it and automaticly replace it with cloned information from the surrounding area with the "Fill single click" tool. It may be called "Fill Single click" but it does a hell of a lot more than clicks! I like to think of it as the audio version of Photoshop's healing brush
