St Compressor

St Compressor
This is a stereo-in, stereo-out compressor. Compressors regulate volume level, and
are also often used to give a "punchy" effect to sounds such as guitars, basses,
pianos, and drums.
Input
-INF, -69.0 to 0.0dB. This sets the input level for the compressor.
Input meter
This meter shows the input level. This is particularly helpful when setting the
compression threshold.
Envelope Select
Left, Right, Left + Right. The action of the compressor is controlled by the level of
the input signal. The Envelope Select determines whether the compressor will be
controlled by the left input only, the right input only, or by the combination of the
left and right signals.
Ratio
1.00:1-20.00:1. This determines how strong the effect of the compressor will be,
expressed in terms of how many dB in input level is required for a 1dB change in
output level.
At 1.00:1, the compressor has no effect. At 20.00:1, a 20dB increase in the input level
(over the threshold) results in only a 1dB change in output.
