UAD Powered Plug-Ins Manual - 267 - 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 (“Fre-
quency” on page 267) and Width (“Width” on page 268) that exceed the
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 (“Width” on page 268), 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.
