About Reverse Audio Online
Reverse Audio is a free browser tool for playing sound backwards. Drop in an audio file, pull the soundtrack out of a short MP4, MOV or WebM video, or record a clip with your microphone, then listen to the original and the reversed version side by side. When it sounds right, download the result as a WAV file for an editor or a video project. A reverse singing mode plays the reversed clip while you record your own attempt, then flips your take back so you can compare. Processing happens locally in your browser: audio files are not sent to a server, and no account is required.
