Noise Gate Expander

The Noise Gate is a version of the Expander which turns the volume all the way down. It generally silences any audio that falls below the threshold level. The attack time is how fast it responds to levels above the threshold, and the release time is how fast it reacts when the levels drop below the threeshold.

This is most useful on percussive instruments such as drums and on spoken word recordings, where you have silent gaps between parts with audio signal, and you know you want the gaps to be completely silent.
