Another peculiarity of this plug-in is that the threshold is not fixed, but relative to the signal, the compressor is driven by the sum of the filters which is computed against the unfiltered signal, this difference is then used as key for the compressor. What happens with this kind of processing is that de-essing takes places even in softer passages where with traditional fixed threshold de-essers the signal must be above the set threshold for de-essing to take place.

The heart of the plugin is the filters bank, here you can set the frequency and level of each filter individually, the bandwidth will always be 1KHz for each filter. For fine tuning you can listen to the output of the filter bank or each filter individually using the key listen buttons.
Each filter can be turned on and off, when turned off the filter is disabled and won’t be considered as compressor sidechain.
