Chapter 40: Precision De-Esser
Note:
When Solo is active, changes to the Threshold and Split controls cannot
be heard.
Width
Width controls the bandwidth of the de-essing
sidechain when in bandpass mode. Bandpass mode is
active when the control is in any position except fully
clockwise.
Smaller values have a narrower bandwidth, causing a tighter, more focused
de-essing effect. Higher values have wider bandwidth, for de-essing when un-
desirable frequency ranges are broader.
When Width is rotated fully clockwise, High Pass mode is activated. In High
Pass mode, Frequency (
“Frequency” on page 428
) defines the cutoff fre-
quency of the high pass filter (instead of the center frequency of the bandpass
filter). High Pass mode is useful when you want to attenuate all frequencies
above the cutoff frequency.
The available range is 0.15 (about 1/6 octave) to 1.61 (about 1 2/3 oc-
taves), plus High Pass mode.
Note:
UAD DSP usage is slightly decreased when Precision De-Esser is in High
Pass mode versus bandpass mode
(unless
“UAD-2 DSP LoadLock” on
page 74
is enabled)
.
Split
Split determines if attenuation (compression) is applied to the
sidechain signal only, or to the entire audio signal.
In normal use Split should be enabled, causing only the “ess” spectrum as de-
fined by Frequency and Width (i.e., the sidechain), to be attenuated. This pro-
vides the most precise de-essing control.
Split can be disabled, which causes the entire input signal to be attenuated
(instead of just the “ess” sidechain) which results in more traditional compres-
sion. However, the sidechain still controls attenuation when Split is off.
Click the Split button to change the mode. Alternately, you can click+hold the
LED area and drag like a slider to change the value.
Note:
UAD DSP usage is slightly decreased when Split is disabled
(unless
“UAD-2 DSP LoadLock” on page 74
is enabled)
