How to Reverse a Voice Recording on Android

By The Reverse Song Team · October 12, 2026

To reverse a voice recording on Android with Reverse Song:

1. Open the app and go to Quick Reverse.
2. Tap record and say or sing something.
3. Stop recording. The reversed version plays straight away.

If the recording already exists on your phone, use the import option in Quick Reverse instead and pick the audio file. Either way, the take is saved to your Library so you can come back to it.

The rest of this guide covers the Player controls, saving and sharing, and what reversing actually does to a file.

Option 1: record and reverse

Quick Reverse is the fastest route. It is built for the moment when you want to hear something backwards right now: a name, a phrase, a laugh, a line of a song.

A few tips for a clean result:

• Hold the phone steady at a comfortable distance from your mouth, about a hand’s width or a little more.
• Keep your fingers off the microphone. On most phones it is a small hole at the bottom edge.
• Record in a quiet room. Background noise reverses too and can swamp quiet speech.
• Leave a moment of silence before and after you speak, so nothing gets clipped.

Option 2: import an existing audio file

If you already have a voice memo, a clip from another recorder app or an audio file someone sent you, you do not need to record again. Choose import in Quick Reverse and pick the file from your phone. Reverse Song reverses it and saves it to your Library alongside your own recordings.

This is handy for reversing a voice note from a friend, or a recording you made before you installed the app.

Playing it back: the Player

Open any clip from the Library to get the Player. You can:

Control	What it does
Forwards / Reversed	Switch between the original direction and the reversed one
Speed slider	Play faster or slower
Pitch slider	Raise or lower the pitch
Chipmunk preset	A high, squeaky voice (free)
Deep voice preset	A low, heavy voice (free)
Slow-mo preset	Slowed-down playback (Premium, or unlock one with a rewarded ad)
Robot preset	A mechanical-sounding voice (Premium, or unlock one with a rewarded ad)

There is also Turn into a challenge, which takes any clip and sets it up as a reverse singing challenge. Record a line of a song in Quick Reverse, and you can turn it into a challenge in a couple of taps. See how the reverse singing challenge works.

Saving and sharing

From a clip you can:

• Share as video: a vertical 9:16 video with an animated waveform, good for stories and short-video apps. If the clip comes from a scored challenge, the score is included.
• Share as audio: an M4A file, for messaging apps or anywhere a video is overkill.
• Save to phone: keep a copy outside the app.
• Challenge a friend: pick a recent clip and send it reversed, with a link to the app, so a friend can try to work out what it says.

Videos carry a small “made with Reverse Song” tag unless you have Premium.

Your recordings stay on your phone

Recordings are stored on your phone. They are not uploaded anywhere unless you choose to share them. The privacy page has the full detail.

What reversing actually does to a file

Digital audio is a long list of numbers called samples. Each one records the position of the sound wave at a tiny moment in time, many thousands of times per second. Reversing a recording means reading that list from the last sample to the first.

That is all it is. Nothing is added or taken away. The same sounds are there, at the same pitch and volume, in the opposite order. That has a few consequences worth knowing.

Pitch stays the same. A high note is still a high note backwards. That is why a melody survives reversal and why the reverse singing challenge works at all.

The order of everything flips, including inside each sound. Words come out in reverse order, and so do the parts of each word. A sharp “t” at the start of a word becomes a clipped snap at the end. An “s” that fades out becomes one that fades in.

Echo and room sound arrive first. Any reverberation in the recording now builds up before the sound that caused it, which gives reversed audio its sucked-in feel.

Reversing twice gives you the original. Flip it back and every sample returns to its place.

Things to try

Once you can reverse anything, a few experiments are worth a minute each:

1. Say your name. Then try to say the reversed version out loud and reverse that. You will hear how close you got.
2. Say a word ending in “s”. Listen to the hiss swell in at the start.
3. Clap once. Reversed, it becomes a strange rising swoosh.
4. Sing one line of Amazing Grace. Then turn it into a challenge and see if you can sing it backwards. Our guide on how to sing a song backwards explains the method.

If something is not working

• Nothing recorded? Check that Reverse Song has microphone permission in your phone’s settings.
• Very quiet result? Move closer to the phone and check you are not covering the microphone.
• Imported file will not open? Try a common audio format, or re-save it from the app that made it.

For anything else, the support page is the place to go. If you are moving from reversing clips to the full challenge, how it works shows the whole flow.
