# Using Loopback Devices

Your virtual audio devices will be available throughout the system. For example, our ”Loopback Audio” device is seen in FaceTime, GarageBand, Skype, and Sound System Preferences.

Any app that receives audio from hardware input devices will also be able to receive audio from Loopback's virtual devices!

That should be enough to get you started. See the full Loopback Manual under the Help menu for more information.
