Rogue Amoeba software, the folks who produce the excellent Audio Hijack Pro, have just announced ‘Airfoil,’ software for the Apple Airport Express that allows you to stream any sound source over Wi-Fi, not just iTunes. While it still isn’t a perfect solution for something like movie playback (where the audio will lag a couple of seconds behind the video, unless you tweak), it fixes an obvious oversight in the Airport Express. I didn’t see anything about the audio stream being encrypted, either, so try to skip that WMV file that recites your credit card number over and over.
Airfoil is $25, but on an introductory sale through March for $20. Windows versions might come out later, but right now it’s OSX only.
