De-Esser
« Back to Glossary Index
A de-esser is an audio processing tool designed to reduce sibilance—the harsh sounds produced by consonants like S, CH, or T, which often stand out too much in vocal recordings. The de-esser works like a frequency-specific compressor, usually targeting the 4 kHz to 10 kHz range. When set properly, it smooths out the voice without dulling it, resulting in a more pleasant and balanced sound.
