Can Voice Memos on a Mac record system audio?

Tested on macOS 26.4.1 (Tahoe), Apple M3 Max, 3 Sept 2026. Updated 2026-09-03.

No. Voice Memos on a Mac records from a microphone only. Apple's guide says: "To create a recording, use the built-in microphone, a supported headset, or an external mic." It has no input for what the Mac is playing. It is a good voice recorder: a Lossless option under Voice Memos > Settings, iCloud sync to iPhone and iPad, and drag-to-Finder export as .m4a. For computer audio you need a different app.

Can Voice Memos record internal audio on a Mac?

No, and there is no hidden setting for it. Voice Memos has no input picker at all: it records from whatever macOS has selected as the input device under System Settings > Sound > Input. That list contains microphones, headsets and audio interfaces, because those are what Core Audio publishes as inputs. The Mac's own playback is not on it.

People try two workarounds. The first is to let the built-in mic pick up the speakers. It works in the sense that something is recorded, but the result has room echo, the noise-suppression tuned for speech chews the music. The second is to install BlackHole and select it as the system input, so Voice Memos records the virtual device. That does work, but it is the same Audio MIDI Setup detour as for Audacity, with the same silent-speakers trap, and at that point Audacity or QuickTime gives you more control for the same effort; see can Audacity record system audio on Mac.

The clean answer for computer audio is an app that reads it through Apple's ScreenCaptureKit with the Screen Recording permission. OBS Studio 30 does that for free with a video container; dedicated recorders write an audio file directly.

How do I record a voice memo on a Mac, and how long can it be?

1. Open Voice Memos. The first launch asks for the Microphone permission.
2. Click the red Record button. Apple's steps: "Click the Pause button to pause recording; click Resume to continue" and "To save the recording, click Done."
3. The memo appears in the sidebar named New Recording, or by location if Location-based Naming is on in Settings. Click the name to rename.

To record in stereo, Apple says to "connect a stereo input source to your Mac", meaning a stereo USB mic or an interface with two inputs selected in System Settings > Sound. The built-in MacBook mics record mono.

Length: Apple publishes no maximum. The practical limits are free disk space and, if iCloud sync is on, iCloud storage, since every memo uploads. A pause counts as one recording, so a multi-hour lecture with breaks stays one file. For anything that long, though, a recorder that shows elapsed size and survives a device hiccup is safer; Voice Memos shows only the elapsed time. Compare with how long you can record audio on a Mac.

Compressed or Lossless: which Audio Quality setting should I use?

Open Voice Memos > Settings. Apple describes the choice: "Choose either Compressed (for lower-quality, smaller files) or Lossless (for high-quality, larger files)." The setting applies to new recordings only.

• Compressed writes AAC in an .m4a container. It is right for voice notes and anything that ends as a transcript.
• Lossless writes Apple Lossless (ALAC) in the same .m4a container, a bit-exact copy of what the mic delivered. Choose it for an interview you will edit, a rehearsal, or a song idea. It costs disk and iCloud space but nothing in fidelity.

There is no bit-depth or sample-rate control; Voice Memos records at the input device's current format as set in Audio MIDI Setup. There is also no WAV option. If a collaborator needs WAV, drag the memo to the Desktop and convert it, or open it in QuickTime and use File > Export As. The conversion routes are in converting a Mac recording to m4a or AAC and its WAV counterpart.

Where are Voice Memos stored on a Mac and how do I get the file out?

Voice Memos does not show its files in Finder as regular documents. The supported way out is described by Apple: "You can drag a recording to a Finder window to save it to the folder of your choice", or click the Share button and choose Mail, Messages, AirDrop, or another app. The dragged copy is an .m4a file named after the memo.

The library itself lives inside your user Library, under Group Containers in a folder belonging to the Voice Memos app. You can copy files out of there, but renaming or deleting inside that folder confuses the app; use drag-out or Share instead.

Sync: with Voice Memos enabled in iCloud settings, recordings appear on every device signed in to the same Apple Account. Apple's guide: "You can listen to your Voice Memos recordings on any Apple device where you're signed in to the same Apple Account." Deleted memos go to Recently Deleted; the Clear Deleted setting decides how long they stay there.

When should I use something other than Voice Memos?

Voice Memos is the right tool when the source is a person in the room and the output is a memo, an interview draft, or a transcript. Reach for something else when:

• The audio is coming out of the Mac: a stream, a call's remote side, a webinar, a DJ set playing in a browser. Voice Memos cannot capture it.
• You need a WAV at a chosen bit depth for a DAW or a client. GarageBand exports WAVE at 24-bit; see recording your voice in GarageBand.
• You want one channel pair of an interface, for example inputs 3 and 4 of an 8-input unit. Voice Memos takes the system input as a whole.
• The take is hours long and you want to see file size growing and know a stalled device will be recovered.

Everything else Voice Memos handles well enough that a paid app is not worth it.

To create a recording, use the built-in microphone, a supported headset, or an external mic.

Where AirCheck fits

AirCheck covers the cases in the last section. It records everything the Mac plays through ScreenCaptureKit with the one-time Screen Recording permission, or any Core Audio input including a selected channel pair of an interface, one source per take, and writes WAV 16-bit, WAV 24-bit or MP3 320 kbps to ~/Music/AirCheck with a visible duration and size. A watchdog reconnects capture within seconds if a device stalls. $39 one-off, macOS 14 or newer. There is no iCloud sync and no transcription.

When you do not need it: For a memo, an in-person interview, or a quick song idea, Voice Memos with Lossless on is free, syncs to your iPhone, and is already installed. You do not need AirCheck for that.

Questions people ask

Can you record a voice memo on a MacBook?

Yes. Open the Voice Memos app in Applications, click the red Record button, and click Done to save. The MacBook's built-in microphones are used unless you select another input under System Settings > Sound > Input.

How long can you record a voice memo on a Mac?

Apple publishes no time limit. The recording continues until you stop it or the disk fills; with iCloud sync on, iCloud storage is the second ceiling because every memo uploads. Pausing keeps everything in one recording.

How do I download or export a recording from Voice Memos on a Mac?

Drag the recording from the Voice Memos sidebar to a Finder window or the Desktop; you get an .m4a file. Or click the Share button and send it to Mail, Messages, AirDrop or another app. Apple documents both routes.

Does Voice Memos record in stereo on a Mac?

Only with a stereo input connected. Apple's guide says to connect a stereo input source, such as a two-input interface or a stereo USB mic, and select it as the input in System Settings > Sound. The built-in mics record mono.
