FabFilter has announced the availability of FabFilter Pro-MB, a brand-new multiband compression/expansion plug-in introducing unique workflow and signal processing advancements.

Featuring free placement of bands anywhere in the spectrum and a newly developed Dynamic Phase processing mode, FabFilter Pro-MB stands out from the plug-in crowd by combining exceptional sound quality with a new way of thinking about multiband dynamics.

FabFilter Pro-MB

A different approach
When working with multiband dynamics, you often focus on one or two specific frequency areas. Instead of conventionally splitting the entire spectrum with crossovers, FabFilter Pro-MB enables you to directly target these areas, simply by creating bands at any frequency range you’re interested in. Think bands, not crossovers! The interface clearly shows that the rest of the spectrum stays untouched. When desired, bands can easily be snapped together to form a traditional crossover system.

Rethinking multiband processing
To achieve truly transparent multi-band processing, FabFilter Pro-MB features an entirely new processing mode: Dynamic Phase. Exclusively developed for Pro-MB, it closely matches the frequency response of conventional multiband processing and results in a flat phase response when no gain changes are applied, but without introducing latency and pre-ringing effects (like Linear Phase processing), or static phase distortion (like Minimum Phase processing). Minor, typically inaudible phase changes are introduced only when the gain of a band is modified. Of course, FabFilter Pro-MB also offers outstanding Linear Phase and conventional Minimum Phase processing modes.

Intelligent, powerful and versatile
Up to six bands can be created, each offering a choice of downward or upward compression or expansion, together with a full set of dynamics controls, from range, ratio and knee control to lookahead and variable stereo linking. Intelligent, highly frequency- and program-dependent algorithms ensure excellent results with all kinds of program material. In Expert mode, more advanced features become available: mid- or side-only processing, external side chain triggering, including the option to trigger on a different, freely configurable frequency range.

Designed for you
Unlike traditional multiband compressors, which can be laborious to set up and control, FabFilter Pro-MB’s large interface is streamlined and uncluttered. Creating, snapping and selecting bands is a breeze, as is adjusting and tweaking multiple selected bands. At any time, the most important settings for all bands are visible at a glance, together with a real-time dynamic gain change curve and spectrum analyzer. Intelligent audio processing combined with optimal interface workflow makes FabFilter Pro-MB an absolute timesaver and a joy to use.
