Phase Inverter
Flip the polarity of a channel, or swap left and right — useful for fixing an out-of-phase recording or cancelling a shared signal between two mic takes.

About this tool
Inverting polarity flips every sample's sign — it sounds identical played alone, but matters when mixed against another signal: two identical signals, one inverted, cancel each other out completely. This is the classic fix for a mic that was wired backwards, or for isolating the difference between two near-identical recordings.
