De-Esser algorithm – introduction
De-Essing is a well-known dynamics tool made
for removing unwanted sibilant sounds. This ver-
sion in System 6000 is improved significantly
– e.g. with 48 bit internal processing – enabling
the process to be performed from 100 Hz to 20
kHz giving the option to also use it as e.g. a de-
popper.
A unique feature allowing the Threshold to oper-
ate either Relatively to average level of the sig-
nal or Absolute to 0 dBFS, makes the De-Esser
work extremely musical e.g. on vocals that have
a constant flaw regardless of the level.
The De-Esser is operating in Stereo, Dual-mono
or M/S processing modes.

Threshold
When the input level exceeds the Threshold, the
De-Esser will be in operation.
Threshold performance depends on the ‘Thresh-
old Mode’ setting (Relative or Absolute) on the
setup page.
Ratio
The Ratio of the gain reduction. When the Ratio
is set to 4:1 it means that for every 4 dB the de-
fined frequency range rises, the output level in-
creases by only 1 dB.
Attack
The Attack time is the response time that the De-
Esser uses to reach the gain reduction specified
by the Ratio parameter.
Release
Release sets the fall-back time of the De-Esser,
after the signal drops below the Threshold.
Frequency
Sets the center frequency of the range the De-
Esser will operate in.
Curve
Sets the bandwidth or Lo/Hi shelf setting of the
range the De-Esser will work in.
