To join multiple audio files into one, upload them in the order you want them to play and the tool combines them into a single continuous track. ClearVoice’s audio joiner does this for free, with no signup, and works with audio or video files mixed together.

Common reasons to merge audio files

How to join audio files, step by step

  1. Open the audio joiner.
  2. Select two or more files, in the order you want them joined -- most file pickers keep the order you select them in.
  3. Click "Process files."
  4. Your combined MP3 downloads automatically, with each file played back-to-back in that order.

Frequently asked questions

Can I reorder the files after selecting them?

The joiner uses the order your browser's file picker gives it, which is usually the order you clicked the files in. If you need a specific order and your file picker doesn't cooperate, select and upload the files one group at a time in the order you want.

Will it re-encode my files? Does that lose quality?

Yes, the combined output is written as a single MP3, regardless of what format you uploaded. For spoken-word content like podcasts and interviews, this is not noticeable.

Is there a limit on how many files I can join?

Up to 10 files per run, each within the usual 300MB / 30-minute cap.

One more thing worth knowing: none of these tools remove background noise -- they just cut, convert, join or measure audio as-is. If your recording still has fan hum, room echo, traffic or a noisy AC unit under the voice, run it through ClearVoice’s AI noise removal afterward -- upload the file, and it comes back clean.
