DYNAMICS -
DE-ESSER
De-esser
A De-esser is used to remove sibilant sounds
from various instruments - especially voices.
To remove only the unwanted (most
significant) “esses” a De-esser must work
dynamically. It could therefore be compared to
Compressor working on a specific frequency
area only. A dynamic filter ensures that the De-
esser only reduces the high frequencies when
they are too loud.
Threshold
Range: -60dB - 0dB
When the Input level for the specified
frequency area exceeds this level the De-
esser will be activated.
Ratio
Range: Off - inf:1
The Ratio of the gain reduction in the specified
frequency area.
Frequency
Range: 1kHz - 20kHz
Sets the center frequency for the area in which
the De-esser should work.
Attack
Range: 0.5 - 50ms
The Attack time is the response time that the
De-esser uses to reach the gain reduction
specified by the Ratio parameter.
Example: If the Input signal suddenly
increases to 4dB above Threshold with the
Ratio set to 4:1 and the Attack set to 20ms, the
De-esser will use 20ms to reach the gain
reduction of 3dB.
Release
Range: 20ms - 7 sec.
Release is the fallback time of the De-esser,
after the signal drops below the Threshold.
FX Lev
Range: -100 - 0dB
The Output level of the De-esser.
