Details on Piezo’s audio handling on the latest versions of MacOS

Beginning with MacOS 14.4, Piezo uses a new audio capture backend. Getting started with Piezo is now much simpler, with no need to adjust your Mac’s security settings, install anything, nor even enter your administrator password. You’ll be up and running in seconds.

Below, you’ll find additional notes about audio capture with Piezo.

The required System Audio Access permission

When you first run Piezo, you’ll be prompted to provide System Audio Access. This permission must be enabled to use Piezo. The Permissions window will guide you through the process.

Once this permission is enabled, you’ll be able to use Piezo to record audio from other apps running on your Mac.

The image above shows the optional Microphone Access permission as well. Enabling this is also recommended, so that you can use Piezo to record from any audio input device you connect to your Mac.

MacOS’s system audio capture indicator

MacOS displays a small purple dot next to the menu bar icon for Control Center to indicate when an application, such as Piezo, is capturing audio via software.

Clicking on the Control Center icon will reveal the full Mac Control Center. At the top of that window, you’ll see the application(s) currently accessing system audio.

Apple provides additional details in the “Use Control Center on Mac” page of their MacOS User Guide.
