About the online audio reverser
This tool flips any audio file end-to-end: upload an MP3, WAV, M4A, OGG or FLAC and you'll get a track that plays from the last sample to the first. No sign-up, no upload to a server — everything happens right in your browser, the file never leaves your device.
Reversing audio is a classic effect for TikTok memes, Reels and Shorts ("play this song backwards"), for hunting urban-legend hidden messages in tracks, for sound design in podcasts and short films, and for music and language experiments.
Choose MP3 output (128 to 320 kbps) or lossless WAV. Length and sample rate match the original exactly, so the reversed track runs the same duration as the source.
When reversing audio comes in handy
TikTok, Reels and Shorts
"Play this song backwards" is a mainstay meme format. Upload your track, reverse it, drop it into your editor — 30 seconds end to end.
Hidden messages in songs
The backmasking urban legend: reverse a chorus and check whether anything intelligible sneaks through. Often the funniest matches show up in the most repeated lines.
Sound design for podcasts and video
Reversed cymbals, guitar swells or vocals create that signature "sucking-in" whoosh — perfect for scene transitions or a build-up before a drop.
Music experiments and language practice
Producers use reversed audio for samples and intros; language learners flip phonetics to train their ear from an unfamiliar angle.
Frequently asked questions
How do I play a song backwards online?
Upload an MP3 or WAV into the box above — the tool reverses the track automatically. Hit Preview to listen, or download the reversed file as MP3 or WAV.
Does my file get uploaded to a server?
No. Decoding, sample-by-sample reversal and MP3 encoding all run in your browser through the Web Audio API. The file never leaves your device — better for privacy and faster too.
Can I reverse audio on my phone?
Yes. The tool runs in mobile browsers — Chrome on Android and Safari on iPhone. No app to install: open the page, upload your file, download the reversed track.
Which output format should I pick?
MP3 (128, 192, 256 or 320 kbps) is best for sharing in messengers and social apps. WAV is lossless and a better choice if you plan to edit the reversed audio further in a video or DAW.
