====== RMS Compressor with Max/Avg IP ======
{{:resources:tools-software:sigmastudiov2:modules:dynamicsprocessors:ipmaxavg.png?150}}
===== Description =====
This Module computes the Gain of the Compressor. Compression happens by taking the RMS of the Average or Max of all inputs, and then looking up for the Gain based on the Compressor Graph.

|RMSTC | 121 | 1 – 10000 db/s | Determines how rapidly the compressor will respond to input signal level changes|
|Hold| 0 | 0-2000 | Controls the time (in ms) the compressor maintains its current output gain setting before it starts decreasing as the input level decrease.|
|Decay| 10 | 1 - 10000 db/s | Controls the rate at which the compressor gain decreases in response to decrease in the input signal level.|
|Soft-knee| - | - | Soft-knee lets the compressor ease into action, making a less-abrupt change from unprocessed signal to compressed signal.|
|Graph| - | - | Compression Editor Graph.|
