Change settings in Voice Memos on Mac
Use settings to set default options for using Voice Memos.
To change these settings in the Voice Memos app on your Mac, choose Voice Memos > Settings.
Choose how long to keep recordings in the Recently Deleted folder. For example, if you choose After 7 Days, your recordings are available in the folder for 7 days. After that, Voice Memos removes them.
See Delete a recording.
Choose either Compressed (for lower-quality, smaller files) or Lossless (for high-quality, larger files).
Have recordings automatically named based on your location. See Allow apps to detect the location of your Mac.
