The clip indicators at the top of each meter indi-
cate clipping at the input or output stage of the
plug-in. Clip indicators can be cleared by click-
ing the indicator.
Gain Reduction Meter
The Gain Reduction meter indicates the amount
the input signal is attenuated, in dB. This meter
shows different colors during de-essing:
Light Orange Indicates that gain reduction is be-
ing applied, but has not reached the maximum
level set by the Range control.
Dark Orange Indicates that gain reduction has
reached the maximum level set by the Range
control.
Frequency
The Frequency control sets the frequency band
in which the De-Esser operates. When HF Only
is disabled, gain is reduced in frequencies within
the specified range. When HF Only is enabled,
the gain of frequencies above the specified value
will be reduced.
This control ranges from 500 Hz (lowest fre-
quency) to 16 kHz (highest frequency).
Range
The Range control defines the maximum
amount of gain reduction possible when a signal
is detected at the frequency set by the Frequency
control.
This control ranges from –40 dB (maximum de-
essing) to 0 dB (no de-essing).
HF Only
When the HF Only button is enabled, gain re-
duction is applied only to the active frequency
band set by the Frequency control. When the HF
Only button is disabled, the De-Esser applies
gain reduction to the entire signal.
Listen
When enabled, the Listen button lets you mon-
itor the sibilant peaks used by the De-Esser as a
side-chain to trigger compression. This is useful
for listening only to the sibilance for fine-tuning
De-Esser controls. To monitor the whole output
signal without this filtering, deselect the Listen
button.
De-Esser Frequency Graph Display
The De-Esser Frequency Graph display shows a
curve that represents the level of gain reduction
(on the y-axis) for the range of the output sig-
nal's frequency (on the x-axis). The white line
represents the current Frequency setting, and
the animated orange line represents the level of
gain reduction being applied to the signal.
