MP3 and M4A
Good for songs, voice notes, and exported clips from phones or editors.
Reverse audio online
Reverse audio online in your browser. Choose an audio file, listen to the backwards version, and download the result as a WAV file.
Reverse Audio Tool is built for one task: turn an audio file around so it plays from the end to the beginning. You can use it for music samples, sound effects, voice clips, podcast edits, and quick backwards audio experiments.
The tool works in the browser. After you select a file, the page decodes the audio, reverses the sample order, lets you preview the result, and prepares a WAV download.
For the core audio reversal step, your file stays on your device. No account, install, or upload is needed.
Good for songs, voice notes, and exported clips from phones or editors.
Useful when you want uncompressed audio and simple editing compatibility.
These formats usually work when your browser can decode them on your device.
The reversed file is exported as WAV so it can be opened by most audio and video tools.
Start with a file you can already play on the same device. If your browser can decode it normally, it is more likely to work here. MP3 and WAV are the safest choices when you are unsure; support for M4A, OGG, and FLAC can differ between browsers.
Long recordings and high-resolution files require more memory because the entire track is prepared on your device. Leave the page open until both players are ready. If a very large file stalls, try a shorter clip or convert it to a smaller MP3 before processing it again.
Listen to the preview before downloading. Reversing changes the order of the sound, but it does not clean up background noise or adjust volume. Those changes are best made in an editor after you save the WAV.
First check whether the file plays normally in the same browser. Then try a current version of Chrome, Safari, Firefox, or Edge. A file extension can occasionally hide an unusual codec, so converting the source to a standard MP3 or WAV is often more effective than simply renaming it. For a phone recording, exporting a fresh copy from the recording app can also resolve decoding errors.
The reversal step takes place locally with browser audio features. Your selected file is decoded in the tab, used to build a new backwards version, and made available through the preview player. The original on your device is never overwritten.
Local processing also means performance depends on your device rather than an upload queue. A modern desktop browser will usually handle larger tracks more comfortably than an older phone, while short voice notes and effects should finish quickly on either.
Closing or refreshing the tab clears the working preview. Download the result before leaving if you want to keep it; you can always select the original again to create a new copy.
Yes. MP3 is widely supported and is a good starting format for songs, voice clips, and downloaded audio.
WAV is accepted by most media editors and avoids another lossy compression step before your next edit.
Yes. Spoken clips, phone recordings, podcast excerpts, and other browser-supported files follow the same steps.
No. The page creates a separate result for preview and download while leaving the source file untouched.
The fastest path is still the tool on the homepage: choose a file, preview it backwards, and download the reversed WAV.
