RMS (Display)

Click here to return to the Dynamics Processors page

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 GainPost-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 KneeSoft-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.
Show GraphOpens the Compression Curve editor window.
