Reversing a sound effect is one of the oldest tricks in audio, and one of the easiest wins for a video or a track. Flip a whoosh, a cymbal or a riser and you get a sound that builds up to the exact moment it ends, perfect for transitions and reveals. Here is how to reverse a sound effect in a couple of taps on your phone, plus the desktop method if you prefer a computer.
Most effects have a sharp start and a long tail. Reverse one and you swap them: the tail becomes a slow swell that rushes toward the hit, then cuts off. A reversed cymbal turns into a riser. A reversed whoosh sucks inward. A reversed reverb tail blooms out of nowhere before a word lands. That build-then-stop shape is exactly why reversed effects feel so satisfying as a lead-in.
A dedicated app is the fastest route because importing, reversing and sharing all live in one place. With Reverse Audio (on iOS and Android):
Everything runs on your device, so there is no upload and nothing to wait for. You can even stack a voice effect on top, or reverse a whole MP3 the same way.
If you would rather use a computer, the free program Audacity does it too: open the file, select the part you want with Ctrl+A, then choose Effect and Reverse. Press play to check it and export when you are happy. It is a few more steps than an app, but handy if you are already editing on a desktop.
Want to flip a whole track instead of a single effect? See our guide to playing any song backwards.
Import or record a sound, hear it backwards, and drop it into your edit in seconds.
Open Reverse Audio, import the sound effect or record one, and the app reverses it automatically. Tap play to hear it backwards, then save or share the reversed file.
A sharp hit becomes a swell that builds up to the moment it ends, so a cymbal turns into a riser and a whoosh sucks inward. That build-then-stop shape is why reversed effects work as transitions.
Yes. Reverse Audio runs on iOS and Android and reverses MP3, WAV, M4A, AAC, FLAC and OGG files on the device, with no upload and no editing skills needed.
As risers before a beat drop, swells into a scene change, reveal and transition stings for TikTok or Reels, and eerie textures in horror or game audio.
