Invert Audio Polarity
Reverse the sign of samples in one or both audio channels. Use polarity inversion for a known wiring correction or to inspect how signals combine.
- Invert left, right or both channels
- Keep sample timing unchanged
- Compare polarity relationships before export
Choose the channel to invert
Apply inversion only to the side that needs correction, or to both for a complete polarity reversal. Each affected sample changes sign.
Distinguish polarity from delay
Polarity inversion is not a time shift. It does not align microphones recorded at different distances or apply an arbitrary phase rotation.
Listen in the intended combination
Inverting a signal alone may sound unchanged. Its interaction with another correlated signal is where cancellation or reinforcement becomes apparent.
Avoid automatic correction assumptions
The tool does not detect wiring errors or decide which setting is correct. Compare the result against your known recording setup.
