SIMPLE WALKTHROUGH
How to reverse audio online
Reverse an audio file or a fresh voice recording in your browser, listen to both versions, and download the backwards result as WAV.
1. Choose a sound
Open the tool and select Choose an audio file to use a recording already on your device. A short voice phrase, hand clap, or single musical note is a good first test. Your browser must be able to play and decode the format. You can also drop a file onto the tool page.
If you want to make a new clip, press Record audio, allow microphone access when your browser asks, and record a few seconds. Press the button again to stop. Play the original track first to check that your microphone captured a clear sound. If it is too quiet, noisy, or distorted, use Record again and try another take.
2. Listen to the original and reversed versions
The page shows two audio players: Original and Reversed. Play them one after the other. The reversed version contains the source samples in the opposite time order, so it starts at the original ending. It does not translate speech or filter out background noise. A clap's short attack and longer fade make the difference especially easy to hear.
Longer clips take more processing time and memory, especially on a phone. If a large file feels slow, test with a shorter clip. When recording sound played by another device, turn down its speaker and keep the microphone a comfortable distance away to reduce clipping and room echo.
3. Download the result
Select Download reversed WAV to keep a copy. WAV works with many audio and video editors, although the file may be larger than an MP3. The page currently exports WAV rather than MP3. Download any result you need before refreshing the page or loading another source.
Try reverse singing
After you add a source, choose Open reverse singing on the tool page. Play the reversed source, try to sing or speak along, and listen to your attempt reversed back. Use headphones: a speaker can leak the guide clip into the microphone and make your recorded attempt harder to judge. Start with a short phrase and repeat until you can compare a clear take.
What happens to my audio?
The processing runs in your browser; the tool does not upload the recording to a server. Your browser still needs access to the selected file or your microphone while you use the page. Keep your original file and your downloaded WAV yourself. If you use another person's music or recording, check permission before publishing or sharing the edited version.
