By setting a noise print in Sountrack Pro, you can pin point a particular noise in your scene for removal. Let's say that after filming a scene, you discover in post that the drone of road construction is competing with your onscreen personalities dialog. Let's face it, you can't always control what's happening in the background of a scene that's being shot guerrilla style. Soundtrack Pro will let you select the problem area, create a noise print, then go back and pin point that noise for reduction in your scene. This technique will take some practice due to the fact that it is possible to reduce the overall sound quality of the scene by performing a noise reduction.
