How to reverse audio on iPhone: 4 ways that actually work
iPhone has no built-in one-tap reverse — Voice Memos can't do it. The two fastest paths: the Reverse Audio PRO app (record or import, tap Reverse, done in about 15 seconds) or the free browser tool on this site — no install, runs locally in Safari, nothing uploaded. GarageBand works too, with a fiddly workaround.
Method 1: Reverse Audio PRO (recommended — about 15 seconds)
Full disclosure: it's our app. It's also genuinely the shortest path — free to download, and reversing is free forever.
- Tap the record button and say your phrase, or import a file from Files or Voice Memos — a live waveform confirms it's picking you up. Tap stop when done.SCREENSHOT SLOT — RECORDING IN PROGRESS
- Tap Reverse. The clip flips instantly.SCREENSHOT SLOT — REVERSE BUTTON ACTIVE
- Press play to hear it backwards. Optional: bend it further with speed (0.25x–3.0x), pitch, or effects, then share or export as WAV, MP3, or M4A.
Method 2: in your browser — free, nothing to install
No install needed for a quick one-off. The free audio reverser runs in Safari on your iPhone: record or drop a file, tap Reverse, download a WAV. It processes everything locally — your audio never leaves the device, nothing is uploaded.
Method 3: what about the apps already on your iPhone?
Voice Memos: no
Voice Memos can trim, duplicate, and enhance recordings, but it has no reverse function and Apple has never added one. To reverse a voice memo, share it out of Voice Memos into a tool that can — see the steps in the next section.
GarageBand: yes, but it's fiddly
GarageBand is free and can genuinely reverse a region — the switch is just buried. Create an Audio Recorder track, import your clip with the Loop Browser (Files tab), switch to Tracks view, tap the region, tap it again and choose Settings, then flip the Reverse toggle. It works and the quality is fine, but there's no A/B compare and exporting means walking the Share menu. Fine for a one-off; tedious for the practice loop the backwards talking challenge needs.
iMovie: for video, and only halfway
iMovie on iPhone has no reverse control at all (the Mac version can reverse a clip, which flips its audio). For a backwards-audio-on-video effect on iPhone, reverse the sound first with Method 1 or 2, then lay the reversed file under your clip in iMovie.
Can I reverse a voice memo on iPhone?
Yes — you just can't do it inside Voice Memos. Share the memo into Reverse Audio PRO or export it to the browser tool; the round trip takes under a minute:
- In Voice Memos, tap ··· on the memo → Share → save to Files, or share straight into Reverse Audio PRO.
- Open the clip in the app (or drop the file into the browser tool above).
- Tap Reverse, then play, share, or export.

Which method should you use?
For one clip right now, the browser tool wins. For anything repeated — practice loops, effects, exports — the app is fastest. GarageBand and iMovie are workable fallbacks if you refuse to add anything.
| Method | Time per clip | Cost | Quality | Export formats |
|---|---|---|---|---|
| Reverse Audio PRO | ~15 seconds | Free; Pro $4.99 once | Lossless reverse | WAV, MP3, M4A |

| GarageBand | 2–3 minutes | Free | Lossless reverse | M4A/AAC via Share sheet |
| iMovie (video) | 3–5 minutes | Free | Tied to video track | Video only (MP4/MOV) |

Frequently asked
Can Voice Memos reverse audio?
No. Voice Memos can trim, duplicate, and enhance recordings, but it has no reverse function on any iOS version and Apple has never added one. Share the memo out to Reverse Audio PRO or the free browser tool on this site — the whole round trip takes under a minute.
Does reversing work offline?
The Reverse Audio PRO app processes everything on your iPhone, so it works in airplane mode — recordings never leave the device. The browser tool needs one page load, then reverses locally in Safari with nothing uploaded. Only the initial download of either requires a connection.
Is Reverse Audio PRO free?
Recording, reversing, and playback are free forever, with no clip limit. The free tier also includes 5 effect uses. Pro is a one-time $4.99 purchase via the App Store and unlocks the 10 effects — Loop, Echo, Reverb, Bass, Filter, Lo-Fi, Flanger, Wave Shaper, Robotize, Compressor — plus export.
What formats can I export?
The app exports WAV, MP3, and M4A (export is a Pro feature; playback and sharing a preview are free). The browser tool downloads a WAV for free. GarageBand shares M4A/AAC through the iOS Share sheet, and iMovie exports video files only.
Can I reverse a song from Apple Music?
Not directly — Apple Music tracks are DRM-protected, so no app or website can process them. You can reverse files you own, like MP3, WAV, or M4A purchases, plus anything you record yourself. For a full walkthrough, the how-to-reverse-a-song guide covers file sources step by step.
