De-Esser – Effects

What the effect is for

S, Z, Sh and T carry their energy between 4 and 10 kHz. Close microphones, bright voices and the compression before them make these sounds sharp. The de-esser measures only that band and reduces it when it exceeds the threshold — for the duration of the sound, then it is gone again.

In band mode only the high band is reduced (8th-order Linkwitz-Riley crossover, the voice below stays exact). Wideband reduces the whole signal and sounds more natural on very harsh sibilance.

Benefits

✓Less harshness without dulling the voice — the range below the crossover stays untouched.
✓Curve and gain reduction on the display, analysis of the whole file with the high-band peak.
✓Attack from 0.1 ms: even short sibilants are caught.
✓Preview: adjust frequency and threshold live until only the S sounds react.

When it makes sense

After the compressor

The compressor lifts sibilance — the de-esser behind it takes it back.

Bright voices

Crossover 6–7 kHz, strength 4–6 dB.

Close condenser microphone

Crossover 5 kHz, wideband for very harsh S.

Controls

Frequency	3–10 kHz crossover, large knob.
Threshold	−50 … −10 dBFS in the high band.
Strength	Maximum reduction 0–12 dB.
Attack / Release	0.1–10 ms / 10–200 ms.
Reduce highs only	Band mode on, wideband off — toggle.

Tips

💡The analysis names the high-band peak: set the threshold 6–8 dB below it.

💡Too much de-essing sounds lispy — 3–6 dB of strength is almost always enough.
