Reverse audio online: record, flip, listen
Record your voice or choose a short audio file. Play it backwards, adjust the speed and try a challenge in your browser. Your audio stays on your device.
Ready when you are
Try WAV, MP3 or M4A. Other audio formats depend on your browser. Files must be 30 seconds or shorter.
Your audio stays on this device. Nothing is uploaded.
Browser recordings are for listening here and are cleared when you leave or reload. To save and share, make your recording in the app.
A few useful answers
Are my recordings uploaded?
No. This web tool processes audio in your browser’s memory. Recordings disappear when you reload or leave. Website hosting and analytics still receive ordinary browsing information, but never your audio.
Does it work on iPhone and Android?
Use an updated browser and allow microphone access to record. If the page does not work inside TikTok or another app, open it directly in Safari or Chrome. You can also try an audio file.
Which files can I reverse?
Try WAV, MP3 or M4A up to 30 seconds and 10 MB. Each format’s support depends on your browser. If a file fails, convert it to WAV or MP3 before trying again.
Can I save or share the audio?
To save or share, make your recording in the SingBack app. The web tool is for listening and practice; it does not export audio or transfer browser takes to the app. To make a video, share the audio from the app and combine it with footage in an editor.
How is this different from the app?
The web tool is free and accepts short audio files. The SingBack app is designed for recording, practice, saving and sharing backwards audio from your phone. The app does not import existing files.
