FabFilter Pro-MB is a versatile multiband dynamics plug-in featuring a uniquely optimized workflow: up to six compression/expansion bands can be placed freely anywhere in the spectrum. High-quality Linear Phase and Minimum Phase processing modes are available, as well as a newly developed Dynamic Phase mode that is even better, offering transparent sound without phase distortion while avoiding linear-phase pre-ringing artefacts. The Pro-MB app filters the microphone input and plays it back in real-time. To use Pro-MB as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-MB will appear in the list of Audio Unit extensions for effect plug-ins in the host app. Key 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 - Unique interactive multiband display, designed for an optimal workflow - Global dry/wet mix from 0% to 200% to easily scale the total effect of the plug-in - High-quality audio processing algorithms with 64-bit internal processing where needed - Up to four times linear-phase oversampling - Accurate and smooth real-time frequency analyzer with pre- and post-processing options and 'freeze' feature - Precise output metering - Undo/redo and A/B comparison "Making multiband compression/expansion easier and more flexible than ever, FabFilter Pro-MB is beautifully designed and sounds superb. Verdict: 9/10!" — Computer Music Magazine "FabFilter Pro-MB is well executed on every level from the intuitive and attractive interface, to the brilliant sound quality." — FutureMusic
