# De-Esser

#### Applicability

This description applies to the Mono and Stereo versions of the De-Esser module.

#### Overview

De-Esser is a module for reducing excessive sibilance or harsh high-frequency components in speech and program material.

#### Processing Principle

The module detects signal energy in a selected frequency range and reduces it according to the configured filter and range settings. Grouping controls whether channels are processed together or independently.
