Mac: Airfoil streams audio from any app to AirPort Express

Rogue Amoeba Software has announced the immediate availability of Airfoil (originally announced as Slipstream), its new Mac software that enables users to send audio from any application (instead of just iTunes) directly to an AirPort Express base station. “Everyone who owns one of Apple’s popular AirPort Express devices will be thrilled to be able to send audio from applications like RealPlayer, Windows Media Player, QuickTime, and Safari right to their remote speakers,” says the developer. “In just seconds, Airfoil can send audio from almost any application on OS X directly to the AirPort Express.” Airfoil is available at an introductory price of $20.
