How to Record Audio on iPhone Without Extra Apps

You need to record something — a voice note, a lecture, an idea for a song, a meeting you’re not typing fast enough to keep up with — and your instinct is to go looking for an app.

You don’t need one. Voice Memos has been sitting on your iPhone since iOS 4, it works with the screen locked, and it does more than most people ever open it up to check.

Voice Memos is the one you already have

Look for an orange icon with a white waveform — it’s usually tucked in the Utilities folder inside your App Library if it’s not already on a Home Screen page.

Open it, tap the big red circle, and it starts recording immediately. Tap it again to stop, and the recording is saved and named automatically (by location if you’ve allowed that, otherwise “New Recording” plus a number).

You can lock your phone or switch to another app mid-recording and it keeps going in the background — useful for a phone call you’re recording notes about on the side, or a long lecture where you want to check something else without losing the take.

Trimming out the dead air

Tap a recording in the list, then tap the three-dot menu and choose Edit Recording. Drag the yellow handles at either end of the waveform inward to select just the part you want, then tap the trim icon and choose Trim to cut it down, or Save a Copy to keep the original untouched alongside the trimmed version.

This is the fastest way to strip the ten seconds of fumbling with the app before you actually started talking.

Cleaning up background noise

While you’re in that same editing view, there’s a wand icon for Enhance Recording.

It runs the audio through on-device noise reduction to cut down room echo and background hum — it won’t rescue a recording made next to a running blender, but for normal room noise, a fan, or light traffic outside, it’s a genuine improvement with one tap, and you can toggle it off if you don’t like the result.

Getting a text transcript

Voice Memos can transcribe your recording to text, live as you record or afterward — swipe up from the top of the waveform during recording and tap the transcript icon to watch it live, or open a saved recording’s menu and choose View Transcript.

Per Apple’s own documentation, transcription requires iPhone 12 or later and works in English (all variants), Spanish, Portuguese, Italian, French, German, Japanese, Korean, Simplified Chinese, and Traditional Chinese — it isn’t available in every country or region.

It’s on-device speech-to-text, so no audio leaves your phone, and you can copy the text out once it’s done rather than relisten to the whole thing to find one sentence.

Getting the file out

Tap the share icon on any recording and you get the normal iOS share sheet: AirDrop it to a Mac, save it to Files, attach it to a Message or an email.

Voice Memos saves everything as an M4A file, which plays fine on Apple devices and most modern apps, but if you’re handing it to software or a person that specifically wants an MP3, save it to Files first and run it through a quick MP4-to-MP3 conversion — the audio conversion works the same way regardless of whether the source is a video or an M4A voice memo.

If the audio already exists inside a video

Sometimes the audio you want isn’t something you’re recording fresh — it’s already sitting inside a video you took or were sent. In that case skip Voice Memos entirely and pull the audio track straight out of the video instead of re-recording it off a speaker.

Frequently asked questions

Does Voice Memos work with the screen locked?

Yes. Once recording starts you can lock the phone or switch apps and it keeps recording until you stop it from the app, the lock screen control, or a paired device.

What file format does Voice Memos save in?

M4A, played by Apple’s own apps and most modern media players. If you need MP3 specifically, convert it after the fact.

Can I edit out a section from the middle of a recording, not just the ends?

Voice Memos’ built-in trim only cuts from the start and end. For removing a chunk out of the middle, you’d need a dedicated audio editor — Voice Memos alone won’t do a mid-recording cut.

Does the noise reduction feature need an internet connection?

No, Enhance Recording processes on-device.

Which iPhones and languages support Voice Memos transcription?

iPhone 12 or later, in English (all variants), Spanish, Portuguese, Italian, French, German, Japanese, Korean, Simplified Chinese, and Traditional Chinese. Availability varies by country or region.

Can I record a phone call directly in Voice Memos?

Not directly on a regular call — iOS doesn’t let Voice Memos capture a live cellular call’s audio. Voice Memos is for recording through the microphone, not tapping into a call.

Will Voice Memos recordings sync across my devices?

Yes, if iCloud sync for Voice Memos is turned on in Settings, recordings show up on your other signed-in Apple devices automatically.
