Airfoil 3 audio utility
Rogue Amoeba on Thursday released Airfoil 3, an update to its software utility for AirPort Express users. Airfoil allows users to send virtually audio to Apple's AirPort Express, from media players such as RealPlayer and QuickTime to audio websites (e.g., Pandora, Last.fm). Version 3 lets users transmit any audio to multiple AirPort Express units, providing "perfect" synchronization between units, the company claims. In addition, audio can now be played through local computer speakers -- in sync with remote playback. Version 3 also enables any Mac to be used as a "virtual AirPort Express" using the included (and free) Airfoil Speakers application. Airfoil Speakers allows any Mac to appear in Airfoil as a standard output, enabling audio to be synchronously transmitted to any Mac.
