Stitching tracks together — songs into a mix, podcast segments into one episode, voice notes into a single file — is one of those tasks that sounds like it needs an audio editor. It doesn’t. You can join multiple audio files into one, in the order you choose, instantly and for free.
Choose two or more audio files. They appear in a list in join order.
Remove or rearrange tracks to set the final sequence.
Click Join — the tracks are combined into one file securely.
Save the joined audio as MP3 or WAV.
Mixing different formats
You don’t have to convert everything first. Because the tracks are re-encoded as they’re joined, you can mix MP3, M4A and WAV files in one merge and they’ll line up cleanly into a single output. Choose MP3 for a small, shareable file or WAV if you’ll keep editing.
Where merging audio helps
- Combining podcast intro, interview and outro into one episode.
- Building a continuous mix from several songs.
- Joining recorded voice notes into a single file.
Tip: Trim each track first with the Audio Cutter and add short fades so the joins between clips sound seamless rather than abrupt.
