About Audio Reverser

A focused place to reverse audio and practice the reverse singing challenge.

A familiar sound, in a different direction

Audio Reverser is for the moment when you want to hear a voice, a song fragment, or a sound effect backwards. The homepage gets you from a local file or a short recording to playback and a downloadable WAV. The reverse singing page helps you keep an original, learn its backwards sounds, and reveal a separate imitation.

Two focused experiences

Reverse Audio: choose a local file or record up to 60 seconds. Compare original and reversed playback, optionally select start and end times, and download a reversed WAV.
Reverse Singing Challenge: keep two independent takes, use slow or looped practice, reverse the imitation, and compare by ear. Both takes can be recorded or imported.

The homepage accepts mono or stereo files up to 25 MB and 5 minutes. The challenge accepts up to 60 seconds per take, also up to 25 MB. Formats depend on the browser decoder. Downloads are 16-bit WAV at the browser-decoded sample rate and original speed.

Built around the sound

The audio tools run locally in browser memory. They do not send your audio to an AI provider or our server. They require no account. Pages and site services still make normal network requests; read the Privacy Policy for that distinction.

The built-in melody and rhythm examples are original synthetic sounds. The spoken example uses a computer voice. Abstract artwork is illustrative, while the interactive waveform is drawn from the audio you load.

We do not identify songs, generate voices, remove vocals, or give a singing score. Learn the controls in the tool guide, and report a problem through Contact.
