What STEREOVAULT does
Flexible Mode is a more creative workflow for individual tracks and stems, with moveable bands per tab. The six tabs are Spread, Creative, Panorama, Width, Rotate and Clean, and the Band Editor with its QuickSplit workflow creates up to six frequency bands quickly. The plugin is available as VST3, AU and AAX for Windows and macOS, and the developer lists native support for Apple Silicon. A trial is available.
Key features
- Smart Presets and reference import. After analysis, the plugin suggests a starting preset for the source, and a reference track can be imported to generate a width preset based on it.
- Level Match. Adjustments are loudness-compensated after analysis, so the change in stereo image can be heard without the louder version seeming better.
- Spread tab. Includes Pristine, a clean M/S-based widening, Diffuse, a smooth allpass-based width, and Vintage.
- Width and Rotate tabs. The Width tab redistributes Mid and Side energy with Blend Balance modes, and the Rotate tab repositions stereo energy across the full signal, Mid or Side.
- Clean tab. Provides transparent Side EQ and Mid EQ, so the user can boost or cut each part of the stereo field.
