Brainworx, the leading developer in Mid/Side mixing tools, has once again launched a game changer: bx_panEQ. This next-level spatial equalizer will forever change the way you sculpt and shape stereo tracks.

Imagine EQ'ing a crash cymbal buried in a pre-recorded stereo mix without affecting instruments panned to other positions in the soundstage. Or how about moving a dead-center lead synth to the left or right of the sound stage to make room for more bass? bx_panEQ offers a comprehensive view into the stereo spatialization of your content and provides intuitive visual controls to help mold the stereo field to your liking. It’s a brand new way to approach stereo-spatial processing.

At the heart of bx_panEQ is a Focus control for each filter; this adjusts how wide the filter’s effect will be in the stereo panorama, allowing for anything from broad strokes to precise adjustments in your mix. The filters' API-style Proportional Q design pinpoints your EQ tweaks by raising the Q factor as gain is increased or decreased from 0 dB, allowing for even more surgical precision. Solo buttons for each band give insight to the exact changes in frequency response by auditioning the pure difference in signal.

Best of all, a Panoramic Spectral Analyzer displays the amplitude of your EQ boosts and cuts across the stereo field and frequency spectrum in real time, intuitively guiding your hand while accurately indicating a blended combination of stereo width and frequency response. You can directly adjust stereo position and relative gain of each band from within this display—a lifesaver when it comes to recording automation or making on-the-fly adjustments. What’s more, bx_panEQ is the first Brainworx plugin to feature a re-sizable interface, allowing you to increase the size of the analyzer to comfortably work on larger displays.

The power unleashed by bx_panEQ in mixing and mastering applications is profound. Stretch the width of a stereo acoustic guitar track by boosting progressively higher frequencies at pan positions from left to right. Reach into the stereo mix of a live concert to tame a boomy hard-panned guitar without affecting other slices of the stereo field. For the mastering engineer, discretely equalize localized spectral imbalances to correct a lopsided mix. For the music producer, automate bands to fly across the spectral analyzer for unique and interesting stereo filter effects. The applications with bx_panEQ are limitless.

bx_panEQ. Point it. EQ it. Done.

Activate the full function 14-day demo with your Plugin Alliance account (no dongle required!) to find out how the magic of bx_panEQ can take your music to places it has never gone before.


  • Three parametric bell-curve filters—each featuring a Gain, Frequency, Q, Pan and Focus control—independently boost or cut EQ at discrete pan positions in the stereo field
  • Innovative Focus control precisely regulates the panoramic width of your EQ adjustments
  • Proportional Q filter design prevents progressive EQ boosts and cuts from spilling over into adjacent bands
  • Color-coded Panoramic Spectral Analyzer plots changes to pan position, frequency and amplitude for stereo content in real time as you make EQ adjustments
  • Visual aid of Spectral Analyzer makes mix decisions easy while providing direct control over stereo position and gain of each band
  • Each filter can be independently bypassed or soloed; when soloed, the signal difference is auditioned, providing critical monitoring on processing
  • Re-sizable interface allows work on larger displays
  • Cut and boost at the same frequency on different points of the panorama to re-place instruments within a full mix
  • Create dramatic panning filter effects with automation.
  • Use bx_panEQ on mono signals to open up frequencies into stereo channels, adding clarity and width
  • ‘Stretch’ sounds by progressively boosting low to high, left to right or vise-versa to create a wider–than-life sound on instruments like guitar and keyboard

    With the bx_panEQ I’m really impressed with the way you can focus on frequencies in the stereo field. I think that’s really important for my older sessions when I go back to them to… Read More

    I’m pretty sure nobody has made anything like this before, which is pretty crazy considering everything’s pretty much been done. It’s gonna kill the market. I was blown away. It’s one more… Read More

    I just finished mastering a track where the artist had used a loop as the main rhythm component. The loop was light in the hi-hat, but using the bx_panEQ I was able to focus on the hi-hat… Read More

    The bx_panEQ is something that’s crazy. I’ve never seen an EQ like this ever in my life, and the fact that I can automate where in the pan my EQ is changing is absolutely revolutionary.… Read More

    A surgical tool with great precision to EQ one side of the stereo image without affecting the other. Can't work without it.

    “Personally, getting my hands on this plugin came at a great time as I was working on a string quartet that wasn’t recorded in the greatest of rooms. I was able to take out resonant frequencies from the violin on one side, whilst boosting some of the body of the cello on the other.

    Likewise, we’ve all had to mix drum tracks and there’s that one cymbal that really bothers you… not any more! This plugin could be a lifesaver! - Gearbot”
