IK Multimedia has bundled their four multi-band processors for one great price! Ideal for mixing or mastering busses, these modules work either in the T-RackS environment or as standalone plugins for any major 32- or 64-bit DAW software.
Multiband processing is a very powerful way of achieving control on the full frequency spectrum of a track which allows to apply the processing only to a selected part of the audio. This is achieved with the use of filters which split the full frequency range into separate bands. This way processing only affects a selected band while the others are left untouched (if desired). This part of the processing is critical as the nature of the filters used for the frequency splitting is crucial in order to achieve a transparent and natural sounding separation of the bands, where the crossover points don't generate artifacts.

- Quad Comp
- Quad Lim
Combining the concept of M/S (Mid Side) matrix processing of the stereo field with multiband architecture, Quad Image effectively allows control over the stereo width of each frequency band. Its simple control set notwithstanding the Quad Image is a powerful processor.
As suggested by its name, Quad Comp is a multiband processor that incorporates up to four fully featured compressors of the Opto type, each one operating on a separate, user-definable frequency band.
Quad Lim is the limiter version of Quad Comp, which, according to the limiting principle, has a fixed, infinity-to-1 ratio. Time constants and makeup gain are user definable for increased control. As with Quad Comp you can adjust the slope of the filters that split the frequency bands, so that dynamics control is broader or sharper, depending on your needs.
As for the Quad Comp the quality and transparency of the filters used for the band splitting was particularly important so that no artifacts or ringing are generated at the crossover points.
De-essing is also known as "frequency dependent compression," but whatever you call it, the idea is to control excessive sibilance (exaggerated 's' sounds), which can be particularly problematic on vocal tracks. The multiband capability is a feature that puts the De-Esser ahead of the competition making it precise and versatile on top of good sounding.
