Play anything backwards.
Record your voice in Reverse Audio PRO, tap reverse, and hear it flipped on iPhone or Android — then bend it with speed, pitch, and ten studio effects. Everything runs on your device. Nothing is uploaded, ever. Free to start; a one-time $4.99 unlocks the whole deck.
Three taps, start to share
Tap the mic and speak. A live waveform tracks every word as you record.
One tap flips the recording end-to-front — instantly, on your device.
Listen, tweak speed and pitch, then export or share in three formats.
Beyond reverse
Free online tools stop at reversing. The app is a full deck.
0.25x to 3.0x — slow a phrase to a crawl or chipmunk it.
±12 semitones, independent of speed.
WAV, MP3, or M4A — share straight from the app.
See the recording as it happens, scrub as it plays.
What people reverse
Record a phrase, reverse it, learn to imitate it — then reverse your imitation. The loop behind the viral challenge.
How the challenge works →Sketch reversed-reverb vocals and cymbal swells on your phone before you ever open a DAW.
Make a reverse swell →Reversed speech strips meaning and leaves pure sound — a strange, useful way to study how we talk.
Why it sounds so weird →Free to start. Pro when you want the whole deck.
One-time purchase — no subscription. Bought in the app through the App Store or Google Play.
Questions, answered
Is my audio uploaded anywhere?
No. Recording, reversing, and every effect run entirely on your device — in the app and in the free browser tool alike. There are no accounts and no cloud storage; nothing you record ever leaves your phone or computer.
What do I get free, and what needs Pro?
Free includes unlimited recording, reversing, playback, and 5 effect uses. Pro is a one-time $4.99 purchase — pay once, unlock forever. It adds all 10 effects without limits, speed control from 0.25x to 3.0x, pitch shift, WAV/MP3/M4A export, and removes ads.
Is Pro a subscription?
No. Pro is a one-time $4.99 purchase — pay once and it stays unlocked forever, with nothing to cancel or renew. If you switch phones or reinstall, restore it for free in the app using the same App Store or Google Play account.
What formats can I export?
WAV, MP3, and M4A with Pro. The free browser tool on this site exports WAV at no cost.
Does the app work offline?
Yes. Since nothing is processed in the cloud, everything — recording, reversing, effects, export — works in airplane mode.
Can I reverse a file I already have?
Yes — import an existing recording or drop a file into the free browser tool (MP3, WAV, M4A, OGG, or WebM) and reverse it in seconds.
