Description
This parameter sets the ratio of the target gain applied by the gate versus the
difference between the input signal level and the gate threshold. For example,
if the 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.
