Reason Re Itsy Audio Phase Inverter [win] Instant

: Features dedicated switches to invert the phase (polarity) of the left and right channels independently.

: The Spread knob can be automated using an external LFO via a front-mounted Mod knob for creative stereo effects. Practical Uses

: A "Flip" switch quickly swaps the left and right audio input channels.

: Includes a built-in phase meter to monitor the stereo signal; a reading of +1 indicates a mono/in-phase signal, while -1 indicates a completely out-of-phase signal.

: It provides a single-point tool for reducing stereo fields to mono and managing channel orientation without rack clutter. Itsy Audio Phase Inverter - Reason Studios

: Use the inversion switches to fix phase cancellation when using multiple microphones on the same source, which can otherwise make a track sound "hollow" or "thin".
