01Overview

STEREOVAULT treats stereo width as a processing decision rather than a single widening knob. It analyzes the audio first, offers starting points by source and genre, and then gives you tabs for spreading, panning, rebalancing Mid and Side energy, and correcting the stereo image. Two workflows cover different jobs: Transparent Mode for full mixes and masters, and Flexible Mode for individual tracks and stems. Level Match keeps loudness out of your judgment, and the Stereo Visualiser shows what the stereo image is doing across the spectrum.

Smart presets, level matching and reference import

STEREOVAULT analyzes the audio and suggests stereo width settings for instrument types including mix, music, bass, drums and vocals, across Focused, Balanced, Wide and Super Wide options. After analysis, adjustments are loudness-compensated so you can hear the actual change in width rather than a change in volume.

You can also import a reference track. The plugin generates a width preset based on that reference's stereo profile, which gives you a concrete target when deciding how wide a mix should sound.

Transparent and Flexible workflows with six processing tabs

Transparent Mode is built for clean processing on full mixes and masters, using crossover filters and a shared band layout across tabs. Flexible Mode lets you move bands independently per tab, which suits mixing, sound design and detailed shaping of individual tracks and stems.

The six tabs are Spread, Creative, Panorama, Width, Rotate and Clean. Spread offers Pristine, Diffuse and Vintage widening methods. Creative adds Stretch, Flux, Chorus, Haas and Space. Width redistributes Mid and Side energy with Blend and Balance modes, and Clean provides Mid or Side EQ for per-band correction. The Band Editor and QuickSplit make it quick to set up up to six bands.
