Paul Kafasis, writing on Rogue Amoeba’s weblog:
Perhaps the biggest change in Airfoil is that it now supports sending audio to Bluetooth devices. Airfoil has always been able to send audio to AirPlay outputs, like the Apple TV and AirPort Express. Now, it also works with the thousands of different Bluetooth speakers, headphones, and headsets available. With Airfoil 5, you can stream a single application’s audio to a Bluetooth device (or multiple Bluetooth devices!), and keep the rest of your audio on your Mac.
I was always a huge fan of Airfoil. But after purchasing a Jawbone Jambox, I didn’t have much use for it. This update might get me back on board.
