HoRNet Sybilla Pro

Hornet Sybilla Pro is a multi filter de-esser,  and unlike other traditional de-essers it has 8 different tunable filters to efficiently find siblances and allocate them to the right compressors for subsequent reductions.

It boasts several features such as Intelligent relative threshold, eight filters for sibilance detection, adjustable frequency and level for each filter, switch to turn on and off each filter, key listen for the entire filter bank and each of the filters, meters for each filter, instantaneous gain reduction meter with peak hold, two different compression modes, attack and release setting for the compressor stage and a dry/wet knob.

Another particularity of this plug-in is that the threshold is not fixed, but relative to the signal, the compressor is driven by all the filters which is compared to the unfiltered signal, and the difference is then used as key for the compressor. This allows de-essing to take place even in softer passages.

The key feature of this plugin is the filters bank, where you can set the frequency and level of each filter individually, the bandwidth being by default at 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.

Sybilla Pro offers two compression options, VCA and OPTO, while for each of the modes, attack and release can be set.
