What it is
A dynamic sibilance and harshness reducer built around a single tunable band. A Frequency control (2 to 10 kHz, default 6 kHz) sets where it listens: the "ssss" and "tssss" sounds that get harsh on a hot vocal, or the brittle cymbal top end that fatigues the ear over a full track. It is dynamic, so it only reduces level when that band crosses the threshold, leaving the rest of the signal alone.
How to use it
- Enable the de-esser in the dynamics rack
- Set Frequency onto the harsh or sibilant band (default 6 kHz, range 2 to 10 kHz)
- Set Threshold just below the loudest "S": the meter will show reduction when it engages
- Set Range (max attenuation, typically -4 to -8 dB)
- Tune Attack (2-5 ms catches transients) and Release (20-50 ms lets it breathe)
What it affects
The de-esser only engages when the target band crosses the threshold, so quiet passages are untouched. Pairs well with Surgical Cleanup for isolated tonal resonances and AI Artifact Suppressor for broader shimmer artifacts. Three different tools, three different problems — the de-esser handles the loud sibilance peaks that dynamic processing can fix without a permanent EQ cut.
