Reversing audio is one of those tricks that sounds technical but takes one step. Maybe you want a reverse-cymbal swell rising into a beat, a spooky backwards voice for a video, or you just want to hear what a clip sounds like played in reverse. The reverse audio tool flips it instantly in your browser.
The short version: drop the file in, and it is already reversed. Preview, then download.
How do I reverse an audio file?
Add your file and the waveform flips back to front on its own. There are no settings to fiddle with.
- Add a file. Drop in an MP3, WAV, OGG or M4A.
- Hear it reversed. Press preview to listen to the backwards version.
- Export. Save the reversed clip as MP3 or WAV.
What people use it for
- Build-ups: reversing a cymbal crash or a synth chord creates the rising swell you hear lifting into the drop in dance and pop tracks.
- Backwards speech: a reversed voice is a long-standing effect in film, games and music for an eerie or otherworldly feel.
- Reveals and checks: reversing a clip lets you hear a hidden sound, or simply confirm what is there from a fresh angle.
- Transitions: DJs and editors drop a short reversed snippet before a cut to pull the listener into the next section.
Does it lose any quality?
No. Reversing is just playing the same audio samples in the opposite order, so nothing is added, removed or degraded. The clip is exactly as clean backwards as it was forwards. The only quality decision is the export format: WAV keeps it lossless, MP3 gives a smaller file at high quality.
A nice combination
A reversed clip with a short fade at the front makes the cleanest build-up, because the swell rises smoothly out of silence. Reverse the clip here, then add a fade with the fade tool for that polished, gliding lift.
Why it stays on your device
The flip runs on your own machine. Your file is read locally, reversed in the browser, and saved back to your computer, with nothing uploaded, no watermark and no account. A long track reverses as easily as a short one.
