# Add Audio Sources

Configuring a virtual device which aggregates multiple audio sources is easy too. Just add the audio sources you intend to use with it.

Here you can see a virtual audio device called “Mic & iTunes” which pulls audio from both iTunes and a USB microphone.

We'll set the “Mic & iTunes” device as our input in Skype. When we do, the other caller will hear both vocals (from our microphone) and music (from iTunes).
