About Audio Joiner
Audio Joiner joins, trims, and balances audio files. It runs entirely in your browser, for anyone who needs a quick edit without installing software or handing their recordings to a server.
Principles
- Processing happens on your device
- Your audio is decoded, edited, and exported inside the browser. Source files are not uploaded to a server.
- Nothing to install
- The editor runs in a modern browser, either here on the site or as a Chrome extension.
- Built for precision
- Waveforms show real peaks rather than a smoothed approximation, edits preview instantly, and the export is rendered from the same timeline you hear.
How it works
- 01Add your audio files. They are decoded locally by the browser’s audio engine.
- 02Reorder tracks, trim the ends, set levels, and fade the joints, with instant preview.
- 03Export a single file. The final render happens on your machine and saves straight to your downloads.
