Multi-band compression and expansion are powerful tools, but notoriously difficult to set up and control. Enter FabFilter Pro-MB: making multi-band 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 multi-band 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 time saver

FabFilter Pro-MB introduces a unique Dynamic Phase processing mode. It has virtually the same frequency response as traditional multi-band 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 multi-band display and all the expert features you need, makes Pro-MB both a lifesaver and time saver!

Features

• Up to six processing bands, freely placed anywhere in the spectrum
• Bands can be easily snapped together to form a traditional crossover system
• Unique Dynamic Phase processing mode featuring zero latency, no static phase changes and no pre-ringing artifacts
• Excellent Linear Phase processing mode, eliminating audible artifacts when quickly changing crossover frequencies
• Minimum Phase processing mode
• Handles any form of dynamics processing, from highly transparent compression, limiting and expansion to pumping upward compression and punchy gating
• Fully customizable per band: threshold, range, attack, release, output gain, ratio, variable knee, lookahead (up to 20 ms), variable stereo linking, mid- or side-only processing, external side chain input, triggering on a separate frequency range
• Steepness of each crossover slope can be freely adjusted between 6 dB/oct and 48 dB/oct
• Intelligent, highly program- and frequency-dependent attack and release curves
• Global dry/wet mix from 0% to 200% to easily scale the total effect of the plug-in
• Unique interactive multiband display, designed for an optimal workflow
• Accurate and smooth real-time frequency analyzer with pre- and post-processing options and 'freeze' feature
• High-quality audio processing algorithms with 64-bit internal processing where needed
• Up to four times linear-phase oversampling
• Band solo/mute and bypass options
• Precise output metering
• GPU-powered graphics acceleration
• Double-click text entry of parameter values
• Stereo and mono plug-ins available
• Supports common Pro Tools hardware control surfaces
• MIDI Learn
• Undo/redo and A/B comparison
• Smart Parameter Interpolation
• Sample-accurate automation of all parameters
• Extensive help file with interactive help hints

FabFilter Pro-MB is hands down the most versatile multi-band dynamics processor ever. I love it!
