Audio joiner

Concatenate several audio files into one WAV — reorder the playlist, then join and download.

Audio stays in this browser. Files are decoded, concatenated, and written as one WAV — nothing is uploaded.

Up to 8 files, 100 MiB each, 10:00.0 total. Output is 16-bit 44.1 kHz WAV (stereo or mono, whichever is higher across the inputs). Sample rates are resampled to 44.1 kHz. Gapless playback between files is not guaranteed — a few ms of silence can appear at joins.

How to use

  1. Choose up to 8 audio files.
  2. Order them with the arrows.
  3. Join and download the WAV.
