Bias GateEx Noise Gate
Full-featured noise gate and downward expander.

In dialog recordings, a gate might be used to remove (or minimize) the presence of background noise or room tone that is audible in the amplitude dips between the speaker's words or phrases. In music recordings, a gate might be used to remove or isolate one type of drum from another. By applying Bias GateEx Noise Gate as a downward expander, you can increase the apparent dynamic range of your audio.
