Sybilla Pro is a sophisticated multi-filter de-esser designed to target and reduce sibilance with high precision. Unlike conventional de-essers, it features eight tunable filters that identify the exact frequencies where sibilance occurs. These filters work together to provide a focused signal to the compressor, ensuring effective reduction of harsh sibilant sounds without affecting the overall vocal quality.

This plug-in operates as a wideband de-esser, with the compressor responding to the combined output of the active filters once the signal surpasses the threshold. This approach allows Sybilla Pro to adapt dynamically as the sibilance shifts in frequency, maintaining consistent control and preventing any sibilant peaks from going unnoticed. Its unique design ensures smooth and transparent de-essing across the entire vocal range.

A key innovation in Sybilla Pro is its intelligent relative threshold, which adjusts based on the incoming signal’s characteristics rather than relying on a fixed level. This method enables the plug-in to engage even during softer vocal passages, where traditional de-essers might not activate. Additional features include adjustable frequency and level settings for each filter, selectable filter activation, key listening options, and comprehensive metering for precise monitoring and control.
