A Gate is a threshold-driven gain reduction
process normally used to attenuate a signal
when its level falls below the Threshold.
Setting the Threshold just above a noise
oororbackgroundnoise,forexample,
will allow the Gate to attenuate the source
during periods when the main input (voice,
instrument etc) is silent.
This gate includes a Sidechain Filter
section. This allows you to control what
frequency range is compared to the
threshold level. For instance, you could
limit the sidechain range to only ‘Ess’ vocal
frequencies. In conjunction with a carefully
set threshold this would act as an effective
‘broadband’ De-Esser.
ATTACK
Adjust the Attack time of the Gate
The time taken for the limiter to reach full attenuation.
RELEASE
Adjust the Release time of the Gate
The time taken for the limiter to return to zero attenuation after limiting.
