just wanted to add, and it may have already been touched on, that the Audition version found in the recent CC versions has a tool very similar to the one in Izotope called Sound Removal where you can select a sample (like a clap for instance) and it will go and remove all of them. Works very very well for getting rid of "woooooos" and claps and such. I was stoked to discover they had added that feature.
