Description
This parameter sets the ratio of the target gain applied by the dynamics gate
versus the difference between the input signal level and the gate threshold. For
example, if the dynamics gate ratio is 10 (i.e., 10:1) and the input signal level is
6 dB below the gate threshold, the gate applies -60 dB of gain. This parameter
does not affect the automixer processing.

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.
