What is a DeEsser?
What is a DeEsser? – Have you ever listened to a song where the singer’s “s” sounds seem to pierce your ears? That’s sibilance, and it’s a common culprit behind harsh-sounding vocals. But fear not, audio wizards! There’s a tool specifically designed to combat this issue: the de-sser.

Imagine a compressor, but instead of affecting the entire audio spectrum, it targets a specific frequency range. That’s essentially what a de-esser does. Sibilance resides in the high frequencies, typically between 4 kHz and 10 kHz depending on the voice. A de-esser listens for these frequencies and turns them down only when they exceed a certain threshold.
When to Unleash the De-Esser
Not every vocal recording needs de-essing. It really depends on the severity of the sibilance. Here are some signs that a de-esser might be your friend:
- The “s,” “sh,” “f,” and “ch” sounds are noticeably harsh and fatiguing to listen to.
- Sibilant sounds seem to stand out more than the rest of the vocals.
- You’ve tried EQing to reduce the harshness, but it’s affecting the overall brightness of the vocals too much.
How to Use a De-Esser
De-essers typically have a few controls:
- Threshold: This sets the level at which the de-esser starts to attenuate the signal.
- Frequency: This allows you to dial in the specific frequency range where sibilance occurs.
- Range: This controls how wide the frequency range being affected is.
- Reduction: This determines how much the de-esser reduces the sibilant frequencies.
Here’s a basic approach to using a de-esser:
- Start with a low threshold and reduction. You can always add more later, but it’s easier to dial in subtle changes than fix over-processed vocals.
- Sweep the frequency knob until you hear the sibilance being affected. A little goes a long way, so find the sweet spot where the harshness is reduced without losing the brightness of the vocals.
- Adjust the range if needed. A narrow range will target only the specific sibilant frequencies, while a wider range might affect other high-frequency elements in the vocal track.
Remember: Use your ears! The goal is to achieve a smooth and natural-sounding vocal, not a muffled one. Don’t be afraid to experiment with the settings until you find what works for your specific recording.
With a little practice, the de-esser will become your secret weapon for achieving professional-sounding vocals. So, the next time sibilance rears its ugly head, you’ll know exactly how to tame it!
