Swap Audio Channels
Swap the left and right channels of stereo audio, inspect the change on a dual-channel waveform, and export a WAV file locally.
Step 1
Add your audio
Drop one audio file here, or browse your device. Your file stays in this browser.
Fix recordings with reversed stereo
Use this tool when left and right sound directions are reversed in headphones or a stereo recording was wired in the wrong order.
Channel mapping
Swapping channels does not change duration, sample rate, or audio quality; WAV is ready for further editing.
Your file stays on this device
Web Audio API decodes, remaps, and exports the WAV inside your browser. No account or server-side copy is required.
