About Merge Audio

Join songs, voice notes or recordings into one audio file in the order you set, with optional silence between them. Different formats and sample rates can be mixed.

How Merge Audio works

Merge Audio joins up to 20 audio files end to end, in the order you arrange them. Before joining, every file is brought to the same sample rate (44.1 kHz) and to stereo, so you can mix MP3, WAV, M4A and other formats freely.

You can add one to three seconds of silence between the files, and save the result as MP3, M4A or WAV. Joining runs in your browser, so your recordings are never uploaded.

When to use Merge Audio

  • Join the parts of a recording that your phone saved as separate files.
  • Put several songs together into one mix or playlist file.
  • Combine voice notes into one message to share.
  • Assemble the segments of a podcast or audiobook.
