Chapter 29: Precision De-Esser
Precision De-Esser Controls
Control knobs for the Precision De-Esser behave the same way as all UAD
plug-ins. Threshold, Frequency, and Width values can be modified with text
entry.
Threshold
Threshold controls the amount of de-essing by defining
the signal level at which the processor is activated. Ro-
tate Threshold counter-clockwise for more de-essing.
Signals peaks as determined by Frequency (
) and Width (
Threshold level are compressed by a ratio of 7:1.
The available range is –40 dB to 0 dB.
Speed
Speed determines the response of the sibilance detector. Fast
mode will usually make sibilance reduction more obvious. In
Slow mode the effect is usually more subtle but can produce a more natural-
sounding result. The actual times of the two modes are as follows:
• Fast: Attack = 0.5ms, Release = 30ms.
• Slow: Attack = 2.0ms, Release = 120ms.
Click the Speed button to change the mode. Alternately, you can click+hold
the LED area and drag like a slider to change the value.
Frequency
This control defines the center frequency of the de-esser
when in bandpass mode, or the cutoff frequency of the
de-esser when in highpass mode. For bandpass use,
the value is set to the center of the undesirable fre-
quency range that is to be reduced. For highpass use, the value is set below
the frequency range that is to be reduced. Used in conjunction with the Width
control (
), a broad range of de-essing is possible.
The available range is 2 kHz – 16 kHz.
Solo
The Solo button isolates the de-essing sidechain (the signal defined by
Frequency and Width). Solo makes it easier to hear the problem fre-
quencies to be attenuated.
Click the button to active Solo mode. The button is red when Solo is active.
