In this video we are going to look an overview of a De-esser.

A de-esser is used to reduce excessively sibilant sounds in speech, such as the S, Z, and sh consonants, which can be exaggerated with the use of a microphone. These sibilant signals are usually in the frequency range of 3 to 10kHz.

A de-esser works by compressing a small area of frequencies where the sibilance exists. Whenever the threshold is crossed, those frequencies will be compressed, or reduced.

Using a de-esser is quite simple. All you have to do is find the sibilant frequency by using the frequency parameter. Then use the threshold knob to lower the threshold until you have the desired gain reduction.

Typically, you want to set your de-esser after all your EQ's and compressors have been set. If the EQ's and compressors are set after the de-esser, it will drastically change the way the de-esser works and sounds.

Is there s de-easer out there that limits the sibilants above the threshold rather than compressing it?
