How to use the Reverse Audio

  1. Drop an audio file into the box, or click choose a file.
  2. Reverse is already ticked, so the result plays backwards.
  3. Listen, then click Download.

The reverse singing challenge

  1. Record yourself singing a short line with the voice recorder.
  2. Reverse it here and listen carefully to the backwards version.
  3. Record yourself copying the backwards sound as closely as you can.
  4. Reverse that recording. If you copied well, you'll hear the original line, slightly strange.

Other uses

Reversed cymbals and piano notes make swelling "riser" effects for music and videos. You can also check for hidden backmasked messages in songs.
