How to reverse audio on iPhone and Android in seconds

Cartoon person on a couch holding a phone with a red record button and a flipping waveform, art for reversing audio on your phone.

Reversing audio means playing a sound backwards so the end comes first. People do it to hunt for hidden backmasked messages in songs, to make eerie effects, or just to hear how strange their own voice sounds in reverse. On a phone it takes three taps.

What does reversing audio mean?

A recording is a wave that moves forward in time. Reversing it flips that wave so it plays from the last moment to the first. Speech turns into an alien, garbled version of itself, and music reveals the quirks that the backwards-message legends are built on.

How to reverse audio on your phone

With Reverse Audio on iOS and Android:

1. Record or import a clip. Capture your voice live, or bring in an MP3, WAV, M4A, AAC, FLAC or OGG file.
2. Tap reverse. The clip flips backwards the moment you load it. Play it and scrub the waveform to A/B against the original.
3. Save or share. Export the reversed audio or send it on. Nothing is uploaded, it all happens on your device.

Reverse your voice, a song, or any sound

The same three taps work on anything: a song, a voice memo, a sound effect, or a fresh recording. And because this is Reverse Audio, you can stack a voice effect on top, like demon or chipmunk, for something stranger still.

Reverse your first clip

Record or import, tap reverse, and share in seconds. On iOS and Android.
