Perfect Synchronization
With Airfoil 3 and its support for the AirTunes 2 protocol, audio now plays to all remote AirPort Express units at exactly the same time. Airfoil 2 partially implemented this, but Airfoil 3 really nails it, providing perfect synchronization to multiple AirPort Express units just like iTunes.

Local Synchronization
And just like iTunes, with Airfoil 3, audio played locally plays in sync with remote audio too. No more delays - all your audio plays in perfect sync, everywhere.

Send To Apple TV
With Airfoil 3.1 and the latest Apple TV software, you can now send any audio to your Apple TV! Your Apple TV will show up in Airfoil's list of available outputs, just like a standard AirPort Express, and you'll be able to send to it!

Send To Other Computers, With Airfoil Speakers
Airfoil Speakers works just like a virtual AirPort Express, allowing you to send any audio to other local Macs and Windows machines, in sync. Just run Airfoil Speakers on other computers throughout your house, and they'll show up in Airfoil, just like a standard AirPort Express. Now you can send any audio to other Macs or PCs, in addition to AirPort Express units and Apple TVs!

Airfoil Video Player
With Airfoil Video Player, you can play video on your Mac and listen to audio remotely through your AirPort Express unit. Airfoil Video Player handles local video playback of many different video formats, along with preliminary support for DVD playback. Video is automatically synced with remote audio, for the perfect viewing experience.
