How to join audio files

Add your files. Tap the box and pick two or more audio files. You can add more later.
Put them in order. Use the up and down buttons to reorder, or remove a file you don't need.
Choose a gap and format. A short gap makes separate clips sound less rushed.
Tap Join files and download. Play the result before you save it.

Join a voiceover and background music into one file by adding them in order, or use it to stitch together voice clips.
Add a one second gap between voice clips so each line can breathe.
Make files similar in volume first with our volume booster so the join doesn't jump.

How many files can I join?

Up to 20 at a time. For more, join in batches and then join the results.

Can I mix different formats?

Yes. You can join MP3, WAV and M4A files together. The result is saved as the format you choose.

Does this layer files on top of each other?

No. Files play one after another, not at the same time.

Do you keep my files?

No. We don't store your files.

Is it free?

Yes, with no signup and no watermark. The page shows ads from a third-party ad network, which runs its own code and may use cookies.
