Param

Threshold

determines the dB level at which the gate will close and open

Pre-open

allows the plugin to look ahead and anticipate dB changes that will cause the audio signal volume to surpass the threshold.

Attack

determines how quickly the gate opens when the signal volume rises above the threshold

Release

determines how quickly the gate closes when the signal volume again falls below the threshold

Hold

determines how long to wait after the signal volume falls below the threshold before it begins to close the gate.
