Diamond Cut's new Direct Spectral Editing mode allows you to directly manipulate your music files in the frequency domain. This works like a paintbrush on the sound. You can attenuate (erase) or amplify (highlight) selected areas of a file to eliminate things like coughs or squeaks without affecting the entire frequency range. For example, you could highlight just the 2000-3000Hz area of one word of a vocal performance to bring out the articulation of that word.
