Threshold sets the level at which the gate opens to let the signal through. The meter on the left lines up with
the graph and shows the signal at the input to the gate. The gain reduction meter on the right shows when
the gate is closed. Depth sets how much the signal is attenuated when the gate closes. Attack, Hold,
Release set how fast the gate opens when the signal rises above the threshold, how long it is held open
after the signal falls below the threshold, and how long it takes to attenuate after it closes.
