# Piping Audio Between Apps

Loopback creates your first virtual audio device at launch. You can use the default “Loopback Audio” device to pipe audio between programs without any additional configuration. This is known as a pass-thru device.

Set “Loopback Audio” as the output in apps from which you wish to pull audio, and the input in apps which should receive that audio. That's it — audio will flow out of one application and into another.
