FabFilter 's Pro-MB software plug-in is a professional multiband compressor/expander with six processing bands that can be freely placed anywhere in the audio spectrum. It can be used for audio mixing and mastering applications such as studio recording, post-production, and more.

Instead of conventionally splitting the entire spectrum with crossovers, Pro-MB allows you to create a new band in the frequency range you want to work in. The interactive multi-band display clearly shows which remaining spectrum remains untouched and, if desired, you can join the bands together to recreate a traditional crossover system. Each band is fully customizable with threshold, range, attack, release, output gain, ratio, variable knee, look-ahead, variable stereo link, mid-only or side-only processing, and more.

The Pro-MB features a dynamic phase processing mode that has virtually the same frequency response as traditional multiband processors, but does not introduce latency or pre-touch. Furthermore, it only introduces small phase changes when the gain actually changes. Also included are a Linear Phase mode and a Minimum Phase mode. Combining professional processing with multiband interactive display can help you optimize your workflow.

Pro-MB software features comprehensive MIDI specifications, including MIDI learning, intelligent parameter interpolation for smoother parameter transitions, and supports common Pro Tools hardware control surfaces. The software also offers an extensive interactive help feature and AltiVec and SSE optimization. The plug-in is available in VST, VST 3, Audio Units, AAX Native and AudioSuite formats (64 and 32 bits) and RTAS (in 32 bits).

Exclusive zero-latency dynamic phase processing mode with no static phase changes and no pre-touch artifacts

Handles any form of dynamic processing, from highly transparent compression, limiting and expansion to upward compression and vigorous gating

Each band is customizable with features such as threshold, range, attack, release, output gain, ratio, variable knee, lookahead (up to 20 ms), variable stereo link, mid or side only processing, external side chain input, trigger on a separate frequency range

• The slope of each crossover slope can be freely adjusted between 6 dB/octave and 48 dB/octave

• Global dry/wet mix from 0 to 200% to easily scale the plugin's full effect

• Accurate and smooth real-time frequency analyzer with pre- and post-processing options and 'freeze' feature

• Up to four times greater linear phase oversampling

• GPU-powered graphics acceleration

• Undo/redo and A/B comparison
