How to extract audio from a phone video recording
Phones capture video at whatever resolution they support and audio at 48 kHz AAC, roughly 128 kbps. VideoSplit turns that video file into a clean audio track in seconds — which is exactly what you need for a voice memo, an interview recording, or a quick sound bite.
VideoSplit runs in mobile Safari and Chrome Android, so you can extract without moving the file to a computer first. iOS Shortcuts can even be wired up to drop directly to VideoSplit, though you will still need to tap through the browser UI.
Step-by-step
- Open VideoSplit.io on your phone. Safari on iOS or Chrome on Android. Nothing to install, no Play/App Store detour.
- Tap Upload video and pick the phone video. Grant Photos/Files permission when prompted. The file stays on your device.
- Pick WAV or MP3. MP3 is smaller and easier to send via Messages or email. WAV is preferable if you plan to edit further.
- Download the audio. Saves to your phone's Downloads folder or Files app.
Tips for better results
- iPhone videos over a few hundred MB will tax Safari's memory — on older iPhones, trim the clip in Photos first.
- For interview recordings on a phone, a lapel mic plugged into the phone's headphone or USB-C jack will produce a dramatically cleaner source than the built-in mic.
- Spatial audio captures on iPhone 15/16 get downmixed to stereo on export; the spatial metadata does not carry through.
