Shape your stereo Image

The stereoSPAN plugin interface: a single row of controls for stereo width, bass centering and tonal correction

stereoSPAN shapes the stereo image — from mono to wide, with centered bass, artificially generated stereo information from mono material, and tonal correction.

stereoSPAN is free – no license needed, no restrictions.

Edge warns about this file? That happens because our signing certificate is still new — not because anything is wrong. The installer is properly signed and safe: choose Keep, then run it.

Install

Runs in any DAW with VST3 or AU support — tested on Ableton Live 12, Logic Pro and Reaper.

macOS: Open the disk image (.dmg), double-click Install stereoSPAN and follow the on-screen instructions.
