The FabFilter Mastering Bundle

• The FabFilter Mastering Bundle combines four industry-standard dynamics and frequency-shaping processors specifically engineered for the precision demands of professional mastering. Comprising the Pro-Q 4 equalizer, Pro-C 3 compressor, Pro-MB multiband dynamics processor, and Pro-L 2 limiter, this bundle provides a cohesive, high-resolution ecosystem for controlling loudness, balance, transients, and phase across entire mixes.

Core Plug-ins Included

FabFilter Pro-L 2 (Limiter)

A major update to FabFilter’s reference-grade brickwall limiter, tailored for competitive loudness injection while strictly preserving dynamic integrity.

• Advanced Algorithms: Features four purpose-built limiting styles: Modern (all-purpose), Aggressive (EDM/Rock), Bus (drums and sub-mixes), and Safe (distortion-free protection).

• True Peak Limiting: Includes an integrated true peak limiting mode to prevent inter-sample clipping when hitting target ceilings.

• Broadcast Compliance: Offers comprehensive loudness and true peak metering compliant with global broadcast delivery standards, including EBU R128, ITU-R BS.1770-4, and ATSC A/85.

FabFilter Pro-MB (Multiband Dynamics)

An intuitive, powerful multiband compressor and expander that streamlines complex cross-over frequency management.

• Dynamic Phase Processing: Introduces a unique processing mode that mirrors traditional multiband frequency responses without adding system latency or pre-ringing artifacts, minimizing phase shifts to only when active gain changes occur.

• Linear & Minimum Phase: Includes an excellent Linear Phase mode for mastering fidelity and a traditional Minimum Phase mode for classic hardware behaviors.

• Interactive Display: Uses a drag-and-drop multiband interface to quickly create, snap, and adjust independent bands anywhere across the spectrum.

FabFilter Pro-Q 4 (Equalizer)

The central tool for critical tone shaping, surgical correction, and mid/side master equalization.

• Master-Grade Fidelity: Provides zero latency, natural phase, and premium linear phase modes to preserve phase alignment during major structural adjustments.

• Workflow Ecosystem: Connects directly with other compatible FabFilter instances (like Pro-C 3) for real-time external spectrum viewing and side-chain control.

FabFilter Pro-C 3 (Compressor)

A highly versatile stereo and immersive compressor ideal for adding cohesion, character, or transparent leveling to the master bus.

• Versatile Profiles: Delivers 14 total compression algorithms across modern and classic profiles, including Vari-Mu, Tube, and Upward dynamics.

• Immersive Surround: Fully supports advanced multichannel audio formats up to 9.1.6 Dolby Atmos® with highly customizable channel-linking controls.

Features

• The Complete Mastering Chain: Integrates essential EQ, multi-band, traditional compression, and brickwall limiting stages in one package

• Phase-Accurate Fidelity: Advanced filter design modes optimized to eliminate audio degradation and pre-ringing artifacts during mastering

• Surround & Atmos Ready: Built to manage high-resolution multichannel mixing and immersive format requirements

• Advanced Metering Suite: Real-time visual analyzers with accurate momentary, short-term, and integrated loudness readouts

• Standard FabFilter Utilities: Features perfectly weighted control knobs, interactive MIDI Learn, deep undo/redo history, A/B comparison switching, and smooth parameter interpolation
