HoRNet offers Sybilla de-esser plugin for Windows and macOS free this weekend only (until November 27th, 2022).
Sybilla is an intelligent de-esser designed with one purpose: reduce those sibilants in almost no time.
It works by dividing the input signal into 8 different bands carefully tuned to the sibilant sound frequencies, the output of these filters drives a VCA-modeled compressor that has a smooth and pleasant response. This coupled with envelope followers “perfect for speech” gives Sybilla a very musical sound but effective de-essing.
Sybilla has just two knobs, since the frequency detection is done automatically to always catch the most critical part you only have to decide how much the de-esser should work on those frequencies and if you like some of the original signal mixed in.
Sybilla is available in VST/VST3, AAX and audio unit plugin formats for digital audio workstations on Windows and macOS.
You can download this plugin for free until November 27th, 2022.
