Reverse an audio file so it plays backwards. Great for music production and checking for "backmasking". Runs entirely in your browser.

Optimize for your platform

Sådan fungerer det

Reversing audio plays it back to front, sample by sample. This does it with FFmpeg in your browser — useful for production effects and for checking "backmasking" (hidden reversed messages).

  1. 1
    FFmpeg.wasm loads once
    The WebAssembly build downloads on first use and is cached afterwards.
  2. 2
    You drop in audio
    Your file is read into the browser's memory — never uploaded.
  3. 3
    FFmpeg reverses it
    The areverse filter flips the audio sample order; the result is re-encoded to MP3, all on your CPU.
  4. 4
    You download the reversed track
    Preview it in-page and download the MP3.

Reverse a track entirely on your device — nothing is uploaded.
