Overview

The first, and still the best, M/S EQ plugin
Brainworx's bx_digital was the first commercially available Mid/Side equalizer plugin. Thanks to its latest V3 update, it still reigns supreme as one of the most powerful and flexible EQs for mixing and mastering with a wide range of forward-looking features.

Remarkable control
This 11-band EQ features fully parametric filters available in dual mono, stereo and M/S modes. It provides a stereo widener, mid/side decoder, the pioneering “Mono Maker” summing tool, spectrum-balancing Bass and Presence Shifters, and advanced monitoring and metering capabilities for mastering work.

Now Even More Powerful
The latest V3 iteration of bx_digital, adds even more tools, including a new Dynamic EQ module, API-style Proportional Q filters, notch filters, an extended high frequency band, and even more versatile Bass and Presence Shifters to help unmask the hidden details in your mixes.

Special filters for clearer and cleaner-sounding mixes and masters
V3 is not a "character" EQ. It's eminently pristine, using ultra-transparent filters that minimize phase shift and frequency masking to deliver clearer and more focused mixes and masters. The Bass and Presence Shifters produce opposing boosts and cuts in adjacent bands to prevent excess spectral energy buildup that can make mixes sound boomy, blurry or edgy. Use them to boost your mix's low-bass punch while simultaneously clearing out muddy upper-bass and low-midrange frequencies, or increase presence to spotlight guitars and vocals, while softening searing cymbals.

Dynamic EQing and De-essing
Version 3 has upgraded the prior De-Esser to a much more versatile Dynamic EQ that can compress or upwardly expand any frequency from 20 Hz to 22 kHz. Use it to de-ess sibilant vocals and cymbals, or to automatically attenuate bass frequencies on an acoustic guitar track—but only when the guitar gets boomy. Boost kick drums inside of a finished mix, or tame the high frequencies of a vocal performance, but only when a singer hits the top of their range.

Solo your EQ bands to hear and see your changes better than ever
V3's innovative Solo functions help you make smarter EQ decisions and work even faster. The Auto-Solo and Auto-Listen switches add amazing touch-sensitive functionality to your Gain, Q and Frequency controls. Automatically solo the changes you apply to each band, and see separate frequency-response graphs for each channel to illustrate the results of your tweaks. You'll see and hear your EQ adjustments like never before.

Proportional EQ and transparent pass filters
V3's new Proportional Q filters progressively adapt the bandwidth of your EQ as you increase or decrease gain, focusing your boosts and cuts exactly where they're needed, without tradeoffs in neighboring bands. The high pass and low pass filters now provide more slope options to sculpt your tracks' high and low end to weed out rumble and hiss with greater precision. And the new, global Gain Scale control makes proportional gain changes to all the filters at once, preserving your careful balance as you dial in the perfect magnitude of EQ.

Simple enough for mixing, powerful enough for mastering
You can even scale the power of V3 up and down to meet your needs thanks to separate versions for mixing and mastering. For individual tracks, the "bx_digital V3 mix" plugin simplifies operation by excluding mid/side processing and additional meters. On your main subgroups and the master stereo bus, use the complete "bx_digital V3" plugin to roll out the big guns: a full complement of Mid/Side equalization controls and separate meters for pre- and post-EQ signal levels, L/R balance and correlation. This version also includes advanced imaging controls to let you independently pan your mid and side channels, widen the stereo image, swap left and right channels, and center the stereo image.

Features

  • Operates in stereo, multi-mono, M/S, and includes a unique M/S Recording decoder to process and output Mid/Side signals in real-time with L/R stereo output.
  • Includes a mixing and mastering version of the plugin to simplify and speed up workflow.
  • Includes eleven broadly overlapping bands per channel with fully parametric filters for LF, LMF, MF, HMF and HF.
  • Includes options for notch filtering, low and high pass filtering, and Proportional Q response.
  • Bass Shift and Presence Shift modules each offer three tilt-equalization settings for clean tonal shaping free of artifacts.
  • Dynamic EQ module boosts or cuts only when needed to correct undesirable, momentary peaks or enhance your signal with creative boosts.
  • Gain Scale control proportionately adjusts all gain controls for the main filters at once.
  • Mono Maker folds frequencies to mono below its selected corner frequency, lending focus to any part of your mix and helping to preserve the side channel's headroom when tightening the low-end.
  • Extremely flexible control linking: Each band and filter can be independently linked with its respective counterpart in the opposing channel.
