# Receiving From iOS, iTunes, and More With Airfoil Speakers

Airfoil Speakers is able to receive audio directly from iOS devices, as well as applications including iTunes and Radium. These sources send audio out via the AirPlay protocol, and can select Airfoil Speakers as their remote output. This page provides a simple overview on sending to Airfoil Speakers with these sources.

### Sending Audio From iOS

If you've used AirPlay on iOS to send audio out before, you'll immediately be able to understand using it with Airfoil Speakers. Just launch Airfoil Speakers on your Mac, then tap the AirPlay button in your iOS audio app.

### Sending Audio From iTunes

Sending audio to Airfoil Speakers with iTunes is just like using any other AirPlay output. Just launch Airfoil Speakers on your Mac, then use the AirPlay menu in iTunes to select the desired output.

### License Required

Airfoil Speakers is a complimentary add-on to Airfoil. However, it is not free on its own - it requires unlocking, with an Airfoil license. When receiving audio from a licensed copy of Airfoil, it will automatically be unlocked. Otherwise, you'll need to manually enter your Airfoil license once, in the License window.
