You can listen to your Voice Memos recordings on any Apple device where you’re signed in with the same Apple ID. See See your recordings on all your Apple devices.

Your recording is saved with the name “New Recording” or the name of your location (if Location-based Naming is selected in preferences and you allowed Voice Memos to detect the location of your Mac).
After a recording is saved, you can select it to play or make edits, such as renaming or trimming.
