From the developer:
MR Gate is a full featured expander/gate that can be used to gate noise during quiet sections. It’s a very comprehensive gate implementation with adjustable lookahead, variable ratio, attack and decay times, etc. In addition, it has a scrolling time display that shows the level of the input signal and the gate attenuation, very handy for setting up the parameters.
