FabFilter Pro-MB

Professional multiband compressor and expander plug-in, suitable for any form of dynamics processing, from highly transparent compression, limiting and expansion to pumping upward compression and punchy gating.

Powerful and intuitive

Multiband compression and expansion are powerful tools, but notoriously difficult to set up and control. Enter FabFilter Pro-MB: making multiband dynamics processing intuitive yet powerful at the same time.

A new approach

Instead of conventionally splitting the entire spectrum with crossovers, Pro-MB enables you to directly create a new band at the frequency range you want to work on. Think bands, not crossovers!

The interactive multiband display clearly shows that the rest of the spectrum stays untouched. And if desired, you can easily snap bands together to recreate a traditional crossover system.

Lifesaver and timesaver

FabFilter Pro-MB introduces a unique Dynamic Phase processing mode. It has virtually the same frequency response as traditional multiband processing, but doesn't introduce latency or pre-ringing, and only introduces minor phase changes when the gain actually changes. Of course, we have also included an excellent Linear Phase mode and a traditional Minimum Phase mode.

The powerful combination of high quality processing, optimized workflow using the interactive multiband display and all the expert features you need, makes Pro-MB both a lifesaver and timesaver!

FabFilter goodies

Of course, you also get all the usual FabFilter goodies: perfectly tuned knobs, MIDI Learn, Smart Parameter Interpolation for smooth parameter transitions, an excellent help file with interactive help hints, SSE optimization and much more!
