ADDITIONAL EFFECTS - DE-ESSER

De-esser

A De-esser is used for removing the sibilant sounds from instruments and especially voices. This is done dynamically, which means that it’s not a static EQ filter but a dynamic filter that only cuts into the sound when the high frequencies are loud in the material.

Threshold

When the Input level exceeds the Threshold, the De-esser will be activated, according to the Mode parameter.

Ratio

The Ratio of the gain reduction.When the Ratio is set to 4:1 it means that for every 4dB the defined frequency range rises, the Output level increases by only 1dB.

Attack

The Attack time is the response time that the De-esser uses to reach the gain reduction specified by the Ratio parameter. Example: If the Input signal suddenly increases to 4dB above Threshold with the Ratio set to 4:1 and the Attack set to 20ms, the De-esser will use 20ms to reach the gain reduction of 3dB.

Release

Release sets the fallback time of the De-esser, after the signal drops below the Threshold.

Freq

Sets the center frequency of the range the De-esser should work in.

Curve

Sets the bandwidth or Lo/Hi shelf setting of the range the De-esser should work in.

Mode

Decides how the Threshold shall react. When set to Relative, the Threshold will be relative to the average level of the signal. This means that also soft signals are processed. For signals where the average level is determined by signals outside the frequency range set, e.g. a vocal with sibilance, the Relative setting is useful and very musical. When Mode is set to Absolute, the Threshold set refers to full scale (0dB) and is therefore well suited for limiting the maximum level in a specified frequency range, e.g. the bass.

Monitor

Monitor the Sidechain signal, and hear what the De-esser actually removes from the main signal.
