To extract audio from a video on iPhone, share the video to the AudioMultiCut app: the audio track opens on a waveform, ready to export in full or cut into clips. No computer, no uploading the video to a website, no screen-recording workarounds.
This is one of those jobs iPhones make oddly hard on their own. The Photos app can trim video but will not give you an audio file, and most online extractors want your video uploaded to their servers. A concert video, a filmed lecture, a voice memo someone sent as video: the audio is the point, and it should not require a desktop to get.
Video transcript
[guitar audio from the video plays] Here's the audio from a video, saved as an MP3 on an iPhone. To get it, share the video from Photos to AudioMultiCut, then export the sound. Let's do it step by step, and see exactly where the file ends up. Step one. Open the video in Photos, tap Share, and choose AudioMultiCut. The app opens with the video's sound as a waveform. The video itself stays on your phone. Step two. Make one cut that covers the whole recording. Drag across the waveform, from the very start to the very end. AudioMultiCut exports cuts, so this one cut is your whole audio track. Step three. Tap Share. Under Output, set Format to MP3. Then tap Share again. Step four. In the share sheet, choose Save to Files, pick a folder, and tap Save. So, where is it? Open the Files app, go to that folder, and tap the file. There's your audio. [the saved MP3 plays: guitar] AudioMultiCut also keeps a copy in its Exports tab, where you can play it or share it again. One limit. Exports are free for videos up to ten minutes. Longer videos need a subscription, or a one time unlock. That's it. Video in, audio out. Find AudioMultiCut on the App Store.
The steps
Open the video in Photos or Files, tap Share, and choose AudioMultiCut. The app pulls the audio track and shows it as a waveform. From there, either export the whole track as one file, or mark segments the way you would with any recording: the filmed gig becomes one file per song, the lecture becomes chapters, the interview becomes answers.
Export MP3 for sharing or WAV for further editing, then send the files through Messages, WhatsApp, Telegram, AirDrop, or Files, including several clips in one share.
What it costs
The app is free for recordings up to 10 minutes, which covers most extraction jobs. AudioMultiCut Unlimited, a monthly subscription, removes the length limit for long lectures, sets, and meetings. Apple shows the exact local price before purchase.
On a computer instead
The same job works in the browser at audiomulticut.com: drop an MP4 or WebM into the editor and the audio opens on the waveform, processed locally without an upload. Useful when the video is already on your desktop, or when it arrived through a chat app's web client.
FAQ
Can I extract audio from a video without an app?
On iPhone, not cleanly: Photos trims video but does not export audio. In a desktop or mobile browser, audiomulticut.com extracts audio from MP4 and WebM locally without an upload.
Does the video get uploaded?
No. The app extracts audio on the device, and the browser editor processes the video locally. The video never leaves your phone or computer.
Can I split the audio while extracting it?
Yes, that is the point of doing it in AudioMultiCut: extraction and cutting are one step. Mark the segments you want and export only those.
