The Signal Envelope block measures the rms average value of the input signals.Holds the signal level for time specified in Hold Control(ms) before starting increase/decrease the output signal level,when there is a change in input signal level.
|GUI Parameter Name||Default Value||Range||Function Description|
|RmsTC||120||1 to 10000||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||0||0 to 2000||Controls the time (ms)the envelope maintains the output level before it starts decreasing as the input level decreases|
|Decay(NA for Ext Decay)||10||1 to 10000||Controls the rate at which envelope signal decreases in response to the decrease in the input signal|
|RmsTC||Controls the time constant (TC) in dB/second that is used for calculating the RMS input value.||Float|
|Hold||Controls the time (ms)the envelope maintains the output level before it starts decreasing as the input level decreases||Float|
|Decay||Controls the rate at which envelope signal decreases in response to the decrease in the input signal||Float|
RmsTC = Abs(1 - 10^(RmsTC/(10 * Sampling Rate)
Hold = (int) Sampling Rate * Hold/1000
Decay = 1/10^(Decay * 2 /(10 * Sampling Rate))
