solution to this problem is to compress only
the sibilants, thereby lowering their level
relative to the rest of the track. Processing a

SYBIL uses a digital

the details of the algorithm
are quite complex,

Controls
Gain Reduction Meter
The Gain Reduction Meter
The Gain Reduction Meter
displays the amount of compression taking
place. If the frequency and threshold controls
are set properly, the meter will display little
gain reduction during vowel sounds and soft
consonants, and substantial gain reduction
during sibilants. For this reason, the meter is a
useful tool when setting the other controls.

High Pass Frequency
This control sets the frequency of SYBIL’s
side-chain high pass filter. The goal is to set
the frequency such that the filter passes any
sibilance (thereby keying the compressor), but
not any of the desired signal.

This control sets the threshold level of SYBIL’s
compressor. The range is from 0 dB to -80 dB.
