# Airfoil: Give Your Audio Wings

Send any audio from your Mac to AirPort Express units, Apple TVs, iPhones and iPods Touch, and even other Macs and PCs, all in sync! Airfoil for Mac gives you your audio — everywhere.

With Airfoil, you can transmit sounds from media players like Spotify, Rdio and more, as well as audio from web-based applications like Pandora, Last.fm, and many, many more. You can even stream audio from hardware devices like RadioSHARK, XM and SIRIUS radios, or even a microphone, all around your house.

Airfoil also includes two helpful add-ons. Open Airfoil Speakers on other Macs, PCs, Linux boxes, and even iPhones, iPods Touch, and iPads on your network, and you can use Airfoil to send audio to them! And if you want to watch video on your computer with audio playing remotely, the built-in Airfoil Video Player should do the trick.
