A de-esser is available for all sources. It can be used to apply gain reduction for sibilant frequencies, and is a useful tool for dealing with human speech.
De-esser Parameters
The following parameters are available for the de-esser:
Reduction – is the amount of gain reduction applied to the sibilant frequencies:
Values from 1 to 6 reduce the gain of the unwanted frequencies; the higher the value, the more gain reduction.
Above 6, the gain reduction remains at its maximum, and the affected frequency range broadens.
Type – changes the center frequencies affected by the de-esser. There are two possible options: either female or male. Each option is optimized for either female or male voices.
Operation
To access the parameters, press an Access key (on the fader strip) followed by De-Esser (on the Central Function Keys and/or GUI).
Then adjust the parameters from either the surface or GUI.
On the surface...
There is one page of parameters.
Enable the DeEss soft key to turn on the processing.
Select either the Female or Male soft key to set the voice type.
Turn the Reduction rotary control to increase (or decrease) the amount of gain reduction.
The behavior of the de-esser can be seen by looking at the Dynamics page on the GUI. If the de-esser is enabled, then a red ball appears on the dynamics graph. This represents the output level of the de-esser, and changes dynamically as the signal level varies.
If you select the Dynamics page (on the GUI) and DeEss (on the surface), then you can adjust the de-esser parameters while looking at the dynamics graph.
On the GUI...
All of the parameters are shown on a single page.
Enable the De-Esser button to turn on the processing.
Touch and drag the Type parameter to set the voice type.
Touch and drag the Reduction parameter to increase (or decrease) the amount of gain reduction.
The meters show the levels at the input and output of the de-esser.
