Swap Audio Channels
Exchange the two sides of a stereo recording. Correct reversed left/right placement while keeping the timing and content within each channel.
- Move the left channel to the right
- Move the right channel to the left
- Preserve track duration and sample order
Correct reversed stereo placement
Use the swap when a capture or export has the channels in the wrong order. Both sides move together in one operation.
Check a recognizable reference
Listen for an instrument, speaker or test signal whose expected position is known. Swapping cannot determine the correct artistic placement for you.
Keep timing untouched
Channel exchange does not introduce an intentional delay or reverse playback. It only changes which side receives each signal.
Recognize mono input
A one-channel recording has no left/right pair to exchange. Mono input remains mono.

Swap Audio Channels FAQs
No. Sample signs are unchanged; only the channel positions are exchanged.
Use Audio Channel Extractor to create a mono file from one side.
No. Swapping only exchanges speaker placement; time still runs forward. Use Audio Reverser for backwards playback, or polarity inversion for a signal-sign change. Check a known left-right cue to decide whether channel swapping is needed.
Swap Audio Channels schedules a background render after a setting changes. The completed preview or analysis replaces the previous result automatically. Processing time depends on recording length and device performance; the status message shows when the new result is ready.
