DeEsser does not use a frequency-dividing network—a crossover utilizing lowpass and highpass
lters. Rather, it isolates and subtracts the frequency band, resulting in no alteration of the
phase curve.
The Detector parameters are on the left side of DeEsser’s interface, and the Suppressor
parameters are on the right. The center section includes the Detector and Suppressor displays
and the Smoothing slider.
DeEsser Detector parameters
•
Detector Frequency knob and eld: Rotate to set the frequency range for analysis.
•
Detector Sensitivity knob and eld: Rotate to set the degree of responsiveness to the
input signal.
•
Monitor pop-up menu: Choose the signal type that you want to monitor. Choose Det(ector)
to monitor the isolated Detector signal, Sup(pressor) to monitor the ltered Suppressor
signal, Sens(itivity) to remove the sound from the input signal in response to the Sensitivity
parameter, or O to hear the DeEsser output.
DeEsser Suppressor parameters
•
Suppressor Frequency knob and eld: Rotate to set the frequency band that is reduced when the
Detector sensitivity threshold is exceeded.
•
Strength knob and eld: Rotate to set the amount of gain reduction for signals that surround
the Suppressor frequency.
•
Activity LED: Indicates active suppression in real time.
DeEsser common parameters
•
Detector and Suppressor frequency displays: The upper display shows the Detector frequency
range. The lower display shows the Suppressor frequency range (in hertz).
•
Smoothing slider: Drag to set the reaction speed for the gain reduction start and end phases.
Smoothing controls both the attack and release times, as they are used by compressors.
