Compressor & Gate

Expander Gate

This is a mono-input, mono-output expander and gate. You might think of it as an
inverse compressor; when the input falls below the threshold, the output level is
reduced. This allows you to mute low-level sounds to clean up a recording with
background noise, and can also be used for creative effects, such as gated reverbs.
Input
-INF, -69.0 to 0.0dB. This sets the input level for the gate.
Input meter
This meter shows the input level. This is particularly helpful when setting the gate
threshold.
Input Select
Left. Left + Right. The action of the gate is controlled by the level of the input
signal. The Input Select determines whether the gate will be controlled by the left
input only, or by the combination of the left and right signals. Note that this is a
mono gate only; stereo signals will be merged to mono.
Ratio
1:1.00-1:128.00. This determines how strong the effect of the gate will be, expressed
in terms of how many dB the output level will be reduced for each 1dB the input
signal falls below the threshold. Use lower settings for gentle expansion, and set it
to the maximum value for true gating.
At 1:1.00, the gate has no effect. At 1:10.00, the output gain is reduced 10dB for each
1dB the signal falls below the threshold, creating 10-to-1 expansion. At 1:128.00,
when the input signal falls 1dB below the threshold, the output level will be
reduced by 128dB, creating a full gate.
