How to use Audio Joiner
- Choose two or more audio files (add them one at a time).
- Check the order in the list — remove any you do not want.
- Click Join Audio to merge them into one track.
- Download the joined audio as WAV.
Honest limit: the joined track is downloaded as a WAV file, because browsers cannot encode native MP3. All files are decoded and joined in order, in your browser.
