Peak w/Ext Detector



Description

The Peak w/Ext Detector Compressor block computes the peak level of the control signal, if peak of the signal is more than threshold, signal level is changes to new peak level and if the peak level is below the threshold level, it slowly reaches reaches the new peak level by accounting the hold and decay time.

Configurable Parameters

GUI Parameter NameDefault ValueRangeFunction Description
Hold0 ms0 to 2000 msControls the time (in ms) the compressor maintains its current output gain setting before it starts decreasing as the input level decrease.
Decay 10 dB/s 0 to 10000 dB/sControls the rate at which the compressor gain decreases in response to decrease in the input signal level, e.g. the “Release” time.
SoftKneeFalseTrue/FalseSoft-knee lets the compressor ease into action, making a less-abrupt change from unprocessed signal to compressed signal. If it is not activated, the default is hard-knee behavior, in which compression rate reduces or increases abruptly with the threshold level
TableAll values are 1-Table values are the gain points used to apply for input signal level
IsDBpsTrueTrue/False Enable /Disable the control's Decay either in dB or linear scale
NumChannels11 to 20Number of input and/or output channels. Change in this value requires re-compilation

DSP Parameter Computation

Decay = (20000/Decay)/(FS + 0.0000001) (When Decay is in dBps) or Decay/(FS + 0.0000001) (When Decay is in linear) Hold = FS * Hold/1000
Where FS is the sampling rate
