Looking for a quick and easy way to get rid of those piercing “SSS” and “TTT” sounds in your vocals? Want your final mix to give an all-around smooth and pleasant listening experience? Then look no further! 

Now in the Soundtrap studio, there is a way to tame the harshest and more unpleasant frequencies in your vocals, allowing for a more balanced mix and a more polished and professional sound. 

Say goodbye to sibilance

Introducing the new De-Esser by Soundtrap. This vocal mixing effect is the key to getting your recordings to sit smoothly by removing unwanted and annoying sibilance with just a couple of settings. 

Sibilance refers to the hissing or harsh sound produced by certain consonants, primarily S and T, when recorded into a microphone. This is a common issue in audio production and makes it difficult to blend a singer or rapper’s vocals with instrumental music when mixing.

What does a de-esser do?

A De-Esser is an audio processing tool designed to specifically target and reduce sibilance in vocal recordings. The De-Esser works by detecting specific sibilance frequencies in your voice and meticulously reduces those sounds, leaving the rest of the vocal audio untouched. The outcome is a more natural-sounding and smoother vocal recording.

Put on some headphones and listen to the examples below. Notice how the S-sounds and T-sounds are tamed and sound smoother after Soundtrap's De-Esser has been applied.

Enjoy effortless sibilance reduction with the De-Esser’s simple but powerful UX.

Threshold Control: Adjust the amount of reduction you want to apply to your vocals. The lower you set the threshold bar, the more effect the De-Esser will have on the chosen frequency range.

Real-time Monitoring: Experience instant audio feedback to apply the optimal amount of De-Essing to your vocals.

LED Metering: Visually monitor the effect of the De-Esser through the 4-level LED meter. The meter will instantly light up when the De-Esser activates.
