Using De-Essing Effectively
To use de-essing most effectively, insert the De-
Esser after compressor or limiter plug-ins.
The Frequency control should be set to remove
sibilants (typically the 4–10 kHz range) and not
other parts of the signal. This helps prevent de-
essing from changing the original character of
the audio material in an undesired manner.
Similarly, the Range control should be set to a
level low enough so that de-essing is triggered
only by sibilants. If the Range is set too high, a
loud, non-sibilant section of audio material
could cause unwanted gain reduction or cause
sibilants to be over-attenuated.
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 Level Meters
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 in-
dicate clipping at the input or output stage of
the plug-in. Clip indicators can be cleared by
clicking the indicator.
De-Esser III 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.
De-Esser III
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.
