Level Meter
This meter represents the input signal level in dB, and is in fact the output of the Gate's
envelope follower. Since the envelope follower is driven by the greater of the left or
right channel, this monophonic meter represents the greater of the two input signals.
Gain Reduction Meter
This meter shows the value in dB of the gate control signal which is used to boost or
attenuate the input signal. Its most-rightward maximum value of 0dB represents a
unity gain path through the Gate in its turn-on state. Except for the possibility of the 1
millisecond lookahead latency, the Gate behaves exactly as a straight wire in this
turned-on state. Values less than 0dB represent the amount by which the input signal is
being attenuated as the Gate shuts off.
The most-leftward gain shutoff value achieved by the Gain meter is set by the Max Gain
Reduction parameter (values from -70dB to -infinity are off the meter.) The speed with
which the Gain signal decays from 0dB to the shutoff value can be observed to change
according to the Release time parameter.
