Your sound will take shape here.
One sound. Two ways to play.
Go a little further: learn the backwards sounds, record a new take, and hear the surprise.
Familiar sounds. Unfamiliar shapes.
A voice becomes a texture. A beat becomes a swell. A tiny melody feels new again. Explore the art of listening in reverse.
These are original abstract illustrations, not recordings or real analysis results. Use the audio reverser above to hear your own sound backwards; use the reverse singing challenge for guided two-take practice.
Sound studies
A simple audio reverser. Room to explore.
A file, a voice note, a few sung notes — start with what you already have. Compare the original with its reverse and listen for what changed.
Bring a file
Choose a local MP3, WAV, M4A, or another format your browser can decode. Up to 25 MB and 5 minutes.
Make a sound
Record up to 60 seconds of voice or singing. Permission is requested only when you press Record.
Hear both directions
Switch between original and reversed playback. Pick a small section to hear a detail more clearly.
Keep the reverse
Download the selected sound as a 16-bit WAV at its original speed. Your source file stays untouched.
Less getting ready. More listening.
Small details that make it easier to finish what you came for — or stay for another listen.
How to reverse audio online
From the first click to a sound worth keeping. You can try a sample before choosing a file.
Choose or record
Pick a local file, record a short voice clip, or tap a built-in sample to get started.
Listen backwards
Press Play reversed. Compare it with Play original to hear the change.
Pick your moment
Optional: enter start and end times. Both playback and download use that selection.
Download your WAV
Save the reverse at original speed. MP3 is an input option; this tool exports WAV.

Local file input

Original / reverse
Listen to either direction without replacing your source.
Optional section

Reverse audio: questions, answered
What goes in, what comes out, and what happens to your sound.
Still have questions?
Choose a file or record a voice clip, then press Play reversed. You can compare the original, choose a section, and download the reverse as WAV. No account is required.
Yes, where your browser supports the input format. MP3 and WAV usually work; M4A, AAC, FLAC, OGG, and WebM depend on the browser and codec. Export is 16-bit WAV.
The audio tool processes files and recordings locally in browser memory. It does not upload your audio. The website still makes ordinary network requests for pages, optional analytics, and advertising; see the Privacy Policy.
The tool decodes your input and exports uncompressed 16-bit WAV. A WAV can be much larger than a compressed MP3. It does not recover detail already lost to compression, and export uses the browser-decoded sample rate.
Import mono or stereo files up to 25 MB and 5 minutes. Microphone recording stops at 60 seconds. The singing challenge limits each take to 60 seconds. Very large or unsupported inputs show an error.
Yes. Open Reverse Singing Challenge to keep your original, practice its reverse at a slower speed, record a separate imitation, and reverse that take for the reveal. Use the homepage for quick file or voice reversal.
You know the sound. Meet its other side.
Start with a few seconds. You might want to listen twice.
