Reverse Audio
Play any song or sound backwards. Upload a file, preview the reversed version, then download a WAV — all in your browser, nothing uploaded.
Reversing flips the audio end-to-front, so the last sound plays first. It’s used for reverse-reverb swells, hidden-message effects, transitions and sound design. Processing and export happen entirely on your device.
How to reverse audio
- Upload your file — MP3, WAV, M4A, OGG or FLAC. It is processed on your device.
- Preview — press play to hear it backwards.
- Export — click Download to save the reversed WAV.
What reversing audio is used for
- Reverse reverb & swells — reverse a tail before a downbeat for a rising, sucked-in effect.
- Transitions — reversed cymbals and risers lead into a new section.
- Backmasking & hidden messages — hear what a track sounds like played in reverse.
- Sound design — reversed samples make great textures and impacts.
Free and private
All processing happens locally with the Web Audio API. Your file never leaves your browser, there’s no signup, and the WAV export has no watermark. Want to reverse just a section? Cut it first with the Audio Cutter, then reverse it here.
