•
Release time
(C to D) – The time it takes for the compressed signal to rise to the threshold level once the input level no longer exceeds the threshold.
11.
Ratio slider
– Sets the ratio of input level to output level when the signal exceeds the threshold.
12.
Attack slider
– Adjusts how quickly the compressor reacts to a signal that exceeds the threshold.
13.
Release slider
– Adjusts how quickly the compressor stops compressing when signal falls below threshold.
14.
Gain knob
