Remove sibilance and harshness, fast

You can use T-De-Esser to:

  • Remove harshness from sound sources that were closely mic’d
  • Manage sibilance in vocals and dialog in a transparent manner
  • Treat irregular tonal balance caused by poor recording quality
  • Reduce the glare from unnecessarily bright guitar and piano recordings
  • Tame piercing synth sounds
  • Control the high-frequencies in overheads’ transients, such as snare, hi-hats, or clash
  • Give more dynamic range to your tracks while mastering, due to the reduction of unnecessary harsh frequencies

T-De-Esser can streamline your audio project workflow by saving you both vital time and effort. It works as effectively on individual tracks as it does on buses. It performs admirably in a wide range of implementations, from sound design and post-production to the most demanding of mastering applications.

The magic

Unlike the majority of De-Esser plug-ins available on the market, T-De-Esser gives a pure natural sound while smoothing the high-frequencies.

The only noticeable difference will be the removal of harshness.

Graphic user interface (GUI)

Visuals can distract your hearing, digital graphs are very likely to affect your decision-making when it comes to setting the values. T-De-Esser, however, helps you just stay focused on the output sound, rather than how things change visually as you tweak the settings.

Whilst there are only a few knobs and buttons on the GUI, each has a huge impact on the audio sound improvement. Less is more, so just to avoid getting caught in the trap of making infinite, minuscule tweaks, we made sure only to have the essential options available for you on the GUI.

The options available are designed in a way to quickly give you a pleasant sound in just a few adjustments. 

Quick yet powerful

T-De-Esser has been designed with simplicity in mind. It is fast to set up and easy to use, yet allows you to adjust the processing to your needs.

Turning the processing knob starts the plug-in’s operation, you then set how intense you want to go according to your taste. There are 4 frequency bands available to choose between, depending on where the harshness and sibilance are coming from.

Artist feedback


A De-Esser is a tool for lowering the loudness of high frequencies usually above 1kHz that may cause spitting or piecing when an “ess” or “shh” sound is made.

The most common usage for de-essers is for fixing sibilance issues on vocal recordings, however, as the T-De-Esser works in a different way than regular types of de-essers, it can be useful for several kinds of sound sources, such as drums, guitars, keys, etc.

We recommend using the T-De-Esser as the first instance of your plug-ins chain. However, sometimes it is also ideal to use it after EQ or use a second instance of T-De-Esser after EQ. For example, you may want to fix some harshness and sibilance issues of a recording using a first T-De-Esser instance, then boost more high-end frequencies using an EQ to brighten up the sound and use a second T-De-Esser in the chain to smooth out the boosted high-end.

Of course. We allow users to take advantage of our free T-De-Esser plug-in for their audio projects, whether it's personal or commercial audio projects. However, we do not permit third parties to upload/share or sell our plug-in installers. Please our terms and conditions for more information on this.

The free T-De-Esser doesn't not include the oversampling feature, however, the premium T-De-Esser Pro lets you apply oversampling up to 16X as well as giving you many other options.
