This video describes and demonstrated the features of the Drum Gator plugin.

Drum Gator does not suffer from the issues experienced with traditional noise gates. It uses a transient detection algorithm combined with spectral analysis to provide an almost uncanny ability to remove only the unwanted drum hits while preserving other program material. It can also do things that are not possible with any other noise gate, opening up creative possibilities that were previously unavailable.
