## What this tool does
Swap the left and right channels or phase-invert one side — fix reversed stereo recordings.

## Typical user problems
- A camcorder wired backwards, a mislabeled interview pan, or a vocal you want sunk into the mix — all of these live in which channel carries what. The channels are swapped with a lossless pan remix (or one side is phase-inverted) while the picture is copied untouched.
