01Overview

pure:deess is an effects plugin built around a single job: controlling sibilance. It listens to a speaker or vocalist, identifies sibilant sounds, and processes them toward a target spectrum calculated for that voice. Three controls handle the work: Suppression sets how much reduction is applied, Color sets the tonal character of the result, and Shaping sets how strongly the sibilants are reshaped. The plugin runs on Windows and macOS in VST3, VST2, AU and AAX formats and offers a trial.

How the AI de-essing works

sonible describes pure:deess as a streamlined version of the analysis and processing technology found in its smart:deess plugin. The plugin identifies individual sibilants, then computes a target spectrum for the specific voice and processes each sibilant toward that target.

Because the processing works toward a target rather than simply cutting a fixed frequency band, the plugin can also boost dull sibilants. According to sonible, this can help restore intelligibility in recordings where the s and sh sounds have lost clarity.

Suppression, Color and Shaping controls

The large central dial sets Suppression. At low settings only the louder sibilants are reduced, and turning it up extends processing to smaller details.

Color changes the target character. Soft softens sibilants considerably and suits material where intelligibility matters less, such as backing vocals. Neutral keeps the character of the original sibilants and corrects only harsh resonances. Sharp keeps presence and intelligibility while reducing the harshest peaks.

Shaping controls how strongly the spectral processing pushes sibilants toward the selected Color. Higher values give a more consistent sound, while lower values keep more natural variation.
