Details on Loopback’s audio handling with Audio Routing Kit (ARK) and the ARK plugin

Beginning with MacOS 14.5, Loopback uses new technology to capture audio. This change means getting started with Loopback is now much simpler, with no need to adjust your Mac’s security settings.

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

Initial setup

When you launch Loopback, the Permissions window will guide you through the initial setup process. You’ll be up and running in under a minute.

Install Audio Routing Kit (ARK)

Loopback’s Permissions window

First, you’ll be prompted to install the Audio Routing Kit (ARK). ARK provides audio handling functionality and must be installed to use Loopback.

Enable permissions for ARK

Permissions prompts

After ARK is installed, you’ll also need to enable both System Audio Access permission and Microphone Access permission for ARK. These permissions must be enabled for ARK to allow Loopback to operate.

Loopback Background Item

In addition to the ARK plugin, Loopback also installs a background handler. MacOS will notify you about this:

This background handler enables Loopback’s virtual audio devices to function even when the Loopback application is not open.

MacOS’s system audio capture indicator

MacOS displays a small purple dot next the menu bar icon for Control Center to indicate when an application, such as Loopback, 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.

When using Loopback, audio capture is actually handled by the Audio Routing Kit (ARK) background application. This is the name which will be shown when system audio is being accessed:
