FLUX StereoTool v3 v21.12.0.50123 VST AU AAX WiN macOS x86 x64 [FREE]

FLUX StereoTool v3 is a free stereo imaging and analysis plugin for producers who want to adjust channel balance, shape stereo width, and check phase relationships. It suits hobby musicians working with stereo recordings, layered instruments, or full mixes, combining practical controls with visual metering.

Separate input gain and pan controls let you adjust the left and right channels independently. Each channel also has a polarity switch, useful when troubleshooting a reversed-polarity signal. Global width and pan settings provide further control over the overall stereo placement.

A vectorscope displays the stereo image, while a continuously active phase correlation meter helps you spot potential phase issues. Input and output PPM meters make it easier to monitor levels as you make changes.

Two preset slots hold different parameter setups for quick A/B comparisons. You can also blend between those settings with the morphing slider and automate its movement through your host for changing stereo treatments over time. Open Sound Control support is included, and StereoTool requires neither a dongle nor license activation.
