Description
This parameter sets the RMS level (in dBFS) of the input signal below which the dynamics gate engages.
The level must be below this threshold longer than the gate hold time (set by dp_gate_hold) before the gate
begins to apply a gain change. This parameter does not affect the automixer processing.
