How it works

  1. Drop your audio file. MP3, WAV, FLAC, AIFF, OGG or M4A up to 500 MB — it's decoded locally, nothing is uploaded.
  2. Click Reverse. The audio is flipped end-to-start in your browser and the reversed waveform is drawn so you can see the result.
  3. Listen and download. Play the reversed audio right on the page, then download it in the same format as your source file.

Features

  • One-click reverse. No timeline editing needed — drop, click, done.
  • Visual confirmation. The waveform redraws backwards, so you can check the flip at a glance before downloading.
  • Same-format export. Lossless sources stay lossless (WAV, AIFF, FLAC); lossy sources are re-encoded at high quality.
  • 100% in your browser. Your track never leaves your computer — processing runs locally with ffmpeg.wasm.

FAQ

Is this reverse tool free?

Yes. Anonymous users get 5 free uses per day across AudioKit's free tools — no account needed. A use is only counted when you actually click Reverse; loading and listening is free. AudioKit Premium removes the daily limit.

Is my audio file uploaded to a server?

No. The file is decoded, reversed and re-encoded entirely in your browser with ffmpeg.wasm and never leaves your machine. The only network call is a tiny anonymous counter that tracks your daily free quota.

Which audio formats are supported?

MP3, WAV, FLAC, AIFF, OGG and M4A files up to 500 MB. The reversed file is exported in the same format as the source: lossless stays lossless, lossy formats are re-encoded at high quality.

What is reversing audio used for?

Mostly sound design and arrangement: reversed cymbals and risers to lead into a drop, reversed reverb tails for ghostly vocal intros, swooshes for transitions — or simply checking what a passage hides when played backwards. Reverse the track, trim the part you need, then layer it under the original.

Can I get the original back after reversing?

Yes. Your source file on disk is never modified, so you can always reload it. And since reversing only changes the order of samples, reversing an already-reversed file gives you back the original — no data is lost in the round trip.
