RMS works on a longer average than peak processors, thus allowing some fast loud transients to pass without compression, but operating more on longer segments that exceed the threshold.
Note: For the picture above, the block was chosen to include the /Detect algorithm, shown by the red pin. For this compressor to be active, signal has to be connected to it.
|Post Gain||Post-processing gain, for increasing the overall signal level following dynamics processing.|
|RMS TC (db/s)||Controls the time constant (TC) in dB/second that is used for calculating the RMS input value. The time constant determines how rapidly the compressor will respond to input signal level changes, e.g. the “Attack” time.|
|Hold (ms)||Controls the time (in ms) the compressor maintains its current output gain setting before it starts decreasing as the input level decrease.|
|Decay (db/s)||Controls the rate at which the compressor gain decreases in response to decrease in the input signal level, e.g. the “Release” time.|
|Soft Knee||Soft-knee lets the compressor ease into action, making a less-abrupt change from unprocessed signal to compressed signal. Typically it sounds better. If it is not activated, the default is hard-knee behavior, meaning compression reduces signal level immediately when the threshold is passed.|
