Parish Audio releases Stereo Control, a free stereo utility plugin

Parish Audio Stereo Control stereo imaging free plugin
Words by Mixdown

Width, Mono Bass, side monitoring and independent polarity invert arrive together in a free plugin built for quick imaging checks and phase troubleshooting.

Parish Audio has bundled a handful of the stereo tools into a single plugin. Stereo Control covers imaging, monitoring and channel troubleshooting in one window, so shaping the stereo picture, checking mono compatibility, inspecting the side signal and tracking down phase problems no longer means loading a different utility for each job.

Parish Audio Stereo Control at a glance

  • Stereo Width from fully mono to 200%, with the original image intact at 100%
  • Mono Bass to centre low-frequency content below a chosen cutoff
  • Balance control for quick left-to-right adjustment
  • Mono sum for compatibility checking and Side Solo for isolating the side signal
  • Instant L/R channel swap and independent polarity invert on either channel
  • Real-time left and right output meters plus a correlation meter for spotting anti-phase content
  • Windows VST3 and macOS VST3/AU, free to keep during the launch promotion

Stereo Width runs from fully mono to 200%. At 100% the original image is untouched, lower settings pull it in towards the centre and higher ones widen it by adding more Side information. Mono Bass works on the low end alone, narrowing the stereo image below a set cutoff so the bass stays centred while the width higher up is left alone. A Balance control covers quick left-to-right moves. When it comes to checking and fixing, Mono sums the signal for compatibility, Side Solo isolates the side content, and the two channels can be swapped in an instant. Either channel’s polarity can be inverted on its own to fix a side that’s out of phase. The left and right output meters show levels in real time, and the correlation meter reads how the channels relate, which makes anti-phase content easy to catch before a mix folds to mono.

Stereo Control comes in Windows VST3 and macOS VST3 and AU formats. It’s free for a limited time, and it’s yours to keep if you add it to a Parish Audio account during the promotion.
