This block functions exactly like RMS (gain) with the Stereo 1 RMS algorithm, except that it comes with a signal level display.
The left bar shows the input level and the right bar the compression ratio. The On button toggles the level display on and off.
For a sample design using this block, see the Dynamics Processor Example.
|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.|
