SYBIL
The SYBIL was designed to quickly and easily tame excessive vocal sibilance (ess, tsss, ch, and sh sounds) with a flexible compressor and variable-frequency High Pass filter that ensures you get the best destination for any vocal performance.

The SYBIL includes a flexible compressor with Threshold, Ratio, Attack and Decay controls, a variable frequency high-pass filter that allows you to adjust sibilance reduction for each individual performance to ensure only unwanted sibilance is affected, and a reduction meter of gain that provides a visual indication of the process of removing these and helps in
fine-tuning of other controls.

With SYBIL, everything you need to gain control of vocal sibilance is at your fingertips.

SYBIL is a digital equivalent of a traditional vocal dialer. It is extremely easy to use.
