Free Online Audio Reverser — Play Sound Backwards

Our free audio reverser flips any track so it plays from the end to the start. Drop in a file, click once, and download a perfectly backwards version of your sound. It is a simple idea with surprisingly many uses, and because everything happens in your browser, it is instant and completely private.

For music producers, reversing is a classic studio trick. A reversed cymbal creates the swelling "whoosh" that builds tension before a drop. Reversed vocals, piano chords and guitar notes make haunting, dreamy textures that you cannot get any other way. Many famous records hide reversed sounds in their intros and transitions, and now you can make the same effect in seconds without expensive software.

Content creators use it for funny or eerie backwards-speech effects in videos, TikToks and Reels. Curious listeners use it to hear what a favourite song sounds like played backwards, or to investigate the famous myth of "backmasking" — hidden messages people claim are recorded in reverse in certain tracks. Teachers and students even use it to explore how sound works, and voice actors record a word, reverse it, learn to say the backwards version, then reverse the whole thing again for a strange, otherworldly effect. Whatever the reason, the result is a clean, fully reversed audio file.

It could not be easier to use. There are no settings to learn and no timeline to edit — you drop in a file, press the button, and the entire track is flipped for you in a moment. It works with MP3, WAV, FLAC and other common formats, handles both short clips and full-length songs, and places no limit on how many files you can reverse, so it is just as handy for a quick experiment as it is for a serious music project.

The whole process runs right inside your browser, so your audio is never uploaded to a server. It is fast, free, watermark-free and needs no sign-up. And if you change your mind, reversing the file a second time brings it right back to the original — so you can experiment as much as you like.

Frequently asked questions

Can I reverse it back to normal?▾
Yes. Reversing an already-reversed file returns it to the original order, so you can always undo the effect by running it through again.
What can I use reversed audio for?▾
Common uses include reverse-cymbal swells and transitions in music, spooky or funny backwards-speech effects in videos, and simply hearing what a song sounds like played in reverse.
Does reversing reduce the audio quality?▾
No. Reversing just plays the existing samples in the opposite order, so the sound quality of your file stays the same — it is only the direction that changes.
Is my file uploaded?▾
No. The audio is reversed entirely in your browser, so nothing ever leaves your device.
What format is the output?▾
The reversed file is saved as an MP3 at 192 kbps, ready to play or drop into a project.
