If you are wondering where the audio files of your Apple Voice Memos are, in case you want to browse through them, see their file sizes, and copy or remove them, they are located in the
com.apple.voicememos folder inside of
That is, the
Library folder inside of your macOS username. For instance, if your username was
john, this would be the full path.
These audio recordings might have been recording on your Mac or your iOS devices (such as iPad or iPhone) and synchronized via iCloud. And even when your voice recordings appear in all your devices, Apple doesn't make it easy to find the audio files of your voice memos.
You can also drag and drop the recordings in the macOS interface to a Finder folder or to the desktop, or send them over AirDrop to your laptop from iOS. A tip I usually do is naming the files on iOS so when they're sent over AirDrop they are properly named.
Hope that helps!
