Audio Joiner

Join several audio files into one track, in the order you choose, with an optional crossfade. Everything is decoded and encoded in your browser.

Add up to 12 clips. You can reorder them below before joining.

All clips are decoded to samples, resampled to 44.1 kHz and joined in this tab, so nothing is uploaded. Joining a dozen full-length songs uses a lot of memory; for very long albums, join in smaller batches.

What Is Audio Joiner?

The Audio Joiner combines up to twelve recordings into a single track in the order you arrange them, with an optional crossfade so the joins do not click. Each clip is decoded, resampled to 44.1 kHz and joined sample by sample in the tab, then written as MP3 or WAV. You can reorder or remove files before joining, and the result shows both the total duration and the final size.

Who Uses the Audio Joiner?

Students stitch lecture parts together, podcasters assemble an intro, interview and outro without a DAW, and anyone with several voice memos turns them into one file that is easy to send.

How to Use the Audio Joiner

  1. Add two to twelve audio files to the list.
  2. Move clips up or down and choose a crossfade between 0 and 5 seconds.
  3. Join, preview the track and download the MP3 or WAV.

Why Choose Our Audio Joiner?

  • Reorder or remove clips before joining instead of starting over
  • A short crossfade removes the click at a hard cut
  • MP3 and WAV output from one page, with no audio editor required
