FabFilter Pro-MB is a powerful and intuitive multiband compressor/expander designed to give mixing and mastering engineers total control over dynamics with ease. Unlike traditional multiband processors, Pro-MB’s innovative workflow allows you to create and adjust bands directly in the frequency spectrum — no fixed crossovers, no clutter, just precise, musical results. Whether you’re taming harsh vocals, tightening bass, or adding punch and polish to a mix, Pro-MB delivers transparent, flexible, and natural-sounding dynamics processing.

Key Features of FabFilter Pro-MB

• Flexible multiband architecture: Create up to six fully independent processing bands anywhere in the spectrum — no fixed crossovers required.
• Dynamic Phase processing: Achieve transparent multiband compression with zero latency, no pre-ringing, and minimal phase coloration.
• Three processing modes: Choose between Dynamic Phase, Linear Phase (for mastering-grade transparency), or Minimum Phase (for analog-style warmth).
• Full per-band control: Fine-tune threshold, ratio, attack, release, range, lookahead, stereo linking, and more — independently for each band.
• Intelligent adaptive timing: Program- and frequency-dependent attack/release curves ensure natural, musical response across all material.
• Dynamic flexibility: Handle compression, expansion, gating, limiting, or even upward compression — all from one intuitive interface.
• Interactive multiband display: See and shape your dynamics directly with drag-and-drop precision.
• Adjustable crossover slopes: Define band transitions anywhere between 6 dB/oct and 48 dB/oct for smooth or sharp separation.
• External sidechain input: Trigger compression or expansion from any signal source for advanced mix control.
• Global Dry/Wet control: Effortlessly blend processed and unprocessed signals from 0% to 200%.
• Built-in spectrum analyzer: Real-time pre- and post-processing visualization with freeze and zoom for detailed analysis.
• Solo, mute, and bypass per band: Focus on specific frequencies for detailed fine-tuning.
• Beautiful Retina interface: A clear, scalable design with smooth metering, responsive controls, and GPU-powered acceleration.
• Precision metering: Visualize gain reduction and output levels with accuracy and clarity.
• Optimized performance: 64-bit internal processing and extreme CPU efficiency for large sessions.
• FabFilter workflow essentials: Includes MIDI Learn, undo/redo, A/B comparison, Smart Parameter Interpolation, and interactive help hints.
• Compatibility: Supports VST, VST3, AU, AAX Native, and AudioSuite formats for both macOS and Windows.

Example Use Cases of FabFilter Pro-MB

• Mix Engineers: Tame harsh sibilance, control low-end energy, or tighten drum busses with precise multiband dynamics.
• Mastering Engineers: Apply subtle, transparent tonal balancing without introducing unwanted artifacts or phase issues.
• Vocal Producers: Smooth out dynamic inconsistencies in vocals, taming sharp resonances or breathy peaks across specific frequency ranges.
• Sound Designers: Create evolving, frequency-dependent textures or rhythmic pumping effects with multiband modulation.
• Post-Production Specialists: Correct tonal imbalances and control dynamic range in dialogue, Foley, or ambient soundtracks.
