Software →HoRNet Sybilla v1.4.0

It works dividing the input signal in 8 different bands carefully tuned to the sibilant sound frequencies, the output of these filters drive 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.
Simple but effective
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.
That's it. Sybilla is easy and effective de-essing.
