Sut Mae'n Gweithio

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