Audio reverser

Play audio backwards: reverse an audio file sample-for-sample and download it as a WAV.

Decoded, reversed, and re-encoded in this browser. Nothing is sent anywhere.

Decodes with the browser's Web Audio decoders and exports uncompressed 16-bit WAV — no lossy re-encode, and no other output format. Files up to 200 MB that decode within a 256 MB PCM budget (about 12 min stereo at 44.1 kHz).

How to use

  1. Choose an audio file.
  2. Reverse it.
  3. Preview and download the WAV.

What it supports

Decodes whatever the browser's Web Audio supports and exports 16-bit WAV only — a true sample-level reversal, so length is unchanged. Files up to 200 MB that decode within a 256 MB PCM budget (about 12 min of stereo at 44.1 kHz).
