工作原理

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.
