To improve de-essing of material that has both
very loud and very soft passages, automate the
Range control so that it is lower on soft sections.
De-Esser III Controls
This section describes controls for the De-Esser
plug-in.
De-Esser Levels Section
These controls let you track input, output, and
gain reduction levels.
Input and Output Meters
The Input and Output meters show peak signal
levels before and after dynamics processing:
Green
Indicates nominal levels.
Yellow
Indicates pre-clipping levels, starting at
–6 dB below full scale.
Red
Indicates full scale levels (clipping).
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 sig-
nal is detected at the frequency set by the Fre-
quency control.
This control ranges from –40 dB (maximum de-
essing) to 0 dB (no de-essing).
The De-Esser has no control to directly ad-
just the threshold level (the level that an in-
put signal must exceed to trigger de-essing).
The amount of de-essing will vary with the
input signal.
