When set to In the compressor is active; when set to Out the compressor is bypassed.
The output gain parameter may be used to increase the gain by as much as 24 dB, or
reduce the gain to nothing. Note that the Out Gain parameter does not control the signal
level when the algorithm is set to Out.
Select the input source channel for side-chain processing—left (L), right (R) or both
(L & R). When set to L & R, the maximum amplitude is used.
Select which input channel will receive compression processing—left, right or both. If you
select left or right, the opposite channel will pass through unaffected.
A switch to set whether the compressor side chain is configured for feed-forward (Out) or
feedback (In).
The time for the compressor to start to cut in when there is an increase in signal level
(attack) above the threshold.
The time for the compressor to stop compressing when there is a reduction in signal level
(release) from a signal level above the threshold. This release time is active while the
signal is reduced by more than the release threshold setting.
The time for the compressor to stop compressing when there is a reduction in signal level
(release) from a signal level above the threshold. This release time is active while the
signal is reduced by less than the release threshold setting.
When the signal is reduced by more than this release threshold, the release time is set by
Rel Time A. Otherwise the release time is set by Rel Time B.
A lowpass filter in the control signal path. It is intended to smooth the output of the
compressor's envelope detector. Smoothing will affect the attack or release times when
the smoothing time is longer than one of the other times.
The time in ms by which the input signal should be delayed with respect to compressor
side chain processing (i.e. side chain predelay). This allows the compression to appear to
take effect just before the signal actually rises.
