### Welcome to Airfoil!

Send any audio 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 take audio from any application and send it to your AirPort Express units, as well as Apple TVs, and even other Macs, PCs, iPhones, iPods Touch, and iPads running Airfoil Speakers!
Transmit audio from RealPlayer, Windows Media Player, QuickTime Player, and other media players. Send audio from web-based applications like Pandora, Last.fm, and others to the AirPort Express. You can even stream audio from audio devices like RadioSHARK, XM and Sirius radios, around your house.
With our free Airfoil Speakers application, you can transmit audio to other Macs, PCs, Linux boxes, and even iPhones, iPods Touch, and iPads on your network too! Now you don't even need an AirPort Express unit to enjoy wireless audio around your house. And if you want to watch video on your computer with audio playing remotely, the built-in Airfoil Video Player just may do the trick. Try them both out, only with Airfoil 3!

### Getting Started

We recommend having a quick read-through of the Airfoil Manual, accessible from Airfoil's Help menu, then diving right in. You can refer back to the full manual for assistance at anytime by accessing it from the Help menu.

### What's New In 3.5.7

- A potential crash when switching sources has been corrected.
- This is the last planned release of Airfoil 3. If you're on Mac OS X 10.6, we recommend upgrading to Airfoil 4.

### What's New In 3.5

- Airfoil and EyeTV from Elgato now work great together - when transmitting audio from EyeTV, Airfoil will adjust the local video to play in sync with remote audio!
- Pulling audio from VMWare Fusion or Parallels Desktop is now much simpler - simply set Fusion or Desktop as the source in Airfoil's Source pop-up, and Airfoil will handle the rest.
- Hijacking audio from Front Row now works more smoothly.
