In a recent Mac 911 column I outlined the procedure for broadcasting applications other than iTunes through Apple’s AirPort Express with the help of Rogue Amoeba’s Nicecast. Reader Carl Westcott writes in with this follow-up to that column:
I read your advice concerning streaming through the Airport Express and am interested in more info. I listen to nfl.com via RealOne Player and a radio station via Microsoft’s Windows Media Player. Now that I have an Airport Express I no longer have a way to patch a cable from my computer into my sound system. Can these other audio programs also be made to stream to an Airport Express?
Although the method I described in the column will work with any application that makes noise, I’m happy to announce that in the near future you won’t need Nicecast to perform this job. Rogue Amoeba is developing a new, easy-does-it utility called Slipstream that does exactly what you want — it sends audio from any application directly to remote speakers attached to an AirPort Express.
Before you “movies on the Mac” readers get all excited, I should mention that Slipstream isn’t currently capable of defying the laws of physics. There’s a delay when playing audio through an AirPort Express — the device needs time to encode and decode audio. That delay makes watching a DVD on the Mac and playing its soundtrack via the AirPort Express an unsatisfactory experience — the picture and sound will be out of sync by at least a second.
Slipstream is still in non-public beta and is due to ship early this year. It will be sold for an introductory price of $20 ($5 off its regular price of $25). When the time comes, check it out.
