Audio Channel Swapper

About Audio Channel Swapper

Our Audio Channel Swapper is a specialized utility designed to fix stereo orientation issues in audio recordings. It's surprisingly common for microphones to be plugged in backwards or for cables to be mislabeled, resulting in audio where the left side is on the right and vice versa. This tool provides a simple, lossless way to flip the stereo field by re-mapping the channels. It uses the FFmpeg 'pan' filter to ensure that the audio data is moved accurately without any quality degradation. As with all our tools, the process is 100% private and happens entirely within your browser. No data is ever sent to a server, making it a secure and efficient way to correct your stereo masters and field recordings.

How to use Audio Channel Swapper

1. Upload the stereo audio file that has reversed or incorrect channel orientation.
2. Verify that the file is indeed a stereo track (mono files cannot be swapped).
3. Click the 'Swap Channels' button to trigger the re-mapping process.
4. Wait a moment as the tool flips the Left and Right audio data.
5. Listen to the preview to confirm the orientation is now correct and download the file.
