Rogue Amoeba on Thursday announced the release of Airfoil 3, a new version of its software used to send audio -- any audio -- to a nearby AirPort Express. It costs $25 to register, and $10 to upgrade from version 2.
With Airfoil installed you can take audio from any application running on your Mac and send it to one, or many AirPort Express units, along with other Macs running Airfoil Speakers software, and listen to the audio in sync over each device. It works with QuickTime Player and other media players, supports Web-based applications like Last.fm, and operates with audio devices like the Griffin RadioShark and XM and Sirius satellite radios.
Airfoil 3 "provides perfect synchronization" to multiple AirPort Express units, just like iTunes, according to the developer. It also manages local synchronization as well, so there are no more delays running music from your own machine, even if music is playing elsewhere.
Airfoil Speakers is another new feature, a "virtual AirPort Express," according to Rogue Amoeba. It lets you send audio to other Macs in sync; they'll show up in Airfoil just like an AirPort Express. And Airfoil Video Player lets you manage local video playback of different video formats, including preliminary support of DVD playback. Lastly, Airfoil 3 offers full support for Mac OS X v10.5 "Leopard."
System requirements cal for Mac OS X v10.4 or later. A downloadable demo is available.
