Multi-Band De-Esser

The multiband capability is a feature that puts the De-Esser ahead of the competition making it precise   versatile on top of good sounding.
When set as 2 band mode the De-Esser works in a broader fashion, effectively reducing the high end content of the area set by the frequency selector. Switching to 3 bands mode allows more precision   control, particualry usefull in situations like vocal tracks where sibilance is in a narrow range,   where there is the need to leave the higher part “air” untouched. The dedicated control set also allows you to precisely tailor the operating mode,   audition the de-essing action   the part of the audio spectrum the processor is working on.
The primary use of this processor is obviously on vocal tracks: this is where the IK Multimedia De-esser shines thanx to its multiband capability which allows to zone in with extreme precision on the troublesome frequency   put it under control.
However, there are several other instances where a de-esser can be a secret weapon where an EQ would be too a drastic solution: hi-hat   crash cymbals can sometimes sound harsh   overly bright in a mix; using an EQ would fix this, but would probably affect also the rest of the high end content of the mix. That`s where frequency conscious compression” comes to the rescue: setting the De-Esser on the right frequency   threshold will allow to reduce the harshness of too bright cymbals only when they are hit,   with the precise setting of release time the action would be unobtrusive   transparent to the rest of the mix.
