DeEsser

This channel strip module reduces excessive sibilance, primarily for vocal and speech recordings. Basically, it is a special type of compressor that is tuned to be sensitive to the frequencies produced by the s-sound. Close proximity microphone placement and equalizing can lead to situations where the overall sound is just right, but there is a problem with sibilants.

Threshold

Sets a threshold for the incoming signal level above which the plug-in starts to reduce the sibilants.

Reduction

Controls the intensity of the de-essing effect.

Auto Threshold

Automatically and continually chooses an optimum threshold setting, independent of the input signal. The Auto Threshold option does not work for low-level signals (<-30 dB peak level). To reduce the sibilants in such a signal, set the threshold manually.

Release

Sets the time it takes for the de-essing effect to return to zero when the signal drops below the threshold.

Solo

Allows you to solo the frequency band to find the appropriate position and width of that band.

Diff

Allows you to listen to the sounds that the de-esser removes from the signal.

Low-Frequency

Allows you to set the low frequency band.

High-Frequency

Allows you to set the high frequency band.

Gain Reduction LED

Indicates the level of compression of the signal.
