Description
|
Ratio
|
This lets you specify the amount of gain reduction applied to the signals above the set threshold. The value is expressed as a ratio, from 1:1 (no reduction) to 16:1 (levels above the threshold are reduced by a factor 16).
|
Threshold
|
This is the threshold level above which the compression sets in. Signals with levels above the threshold will be affected, signals below it will not.
In practice, this means that the lower the Threshold setting, the more the compressor effect.
|
Attack
|
This governs how quickly the compressor will apply its effect when signals rise above the set threshold. If you raise this value, the response will be slower, allowing more of the signal to pass through the compressor unaffected. Typically, this is used for preserving the attacks of the sounds.
|
Release
|
When the signal level drops below the set threshold, this determines how long it takes before the compressor lets the sound through unaffected. Set this to short values for intense, "pumping" compressor effects, or to longer values for a smoother change of the dynamics.
|
Gain meter
|
This shows the amount of gain reduction or increase (in dB), caused by the combined compression and make-up gain.
