MiniMeters on macOS 14.2 and later uses a Core Audio Tap to capture the selected system output device. More info here.
Open MiniMeters and click Settings from the bottom right.
Under the Audio Device panel and choose "Default Output Capture" from the Audio Device section.
A window will pop up requesting System Audio permissions. MiniMeters needs this to monitor your desktop audio. You can revoke this permission at any time from System Settings.
From macOS 13.0 to 14.1 MiniMeters uses ScreenCaptureKit to capture desktop audio. MiniMeters throws out the captured video information as it is unneeded, leaving only the audio.
Open MiniMeters and click Settings from the bottom right.
Under the Audio Device panel and choose "Desktop Audio" from the Audio Device section.
A window will pop up requesting Screen Capture permissions. MiniMeters needs these to set up the session to record. You can revoke this permission at any time from System Settings.
Desktop Audio Capture is not supported on macOS 12 Monterey and prior.
