Slipstream = AirTunes on steroids

Rogue Amoeba Software has an app in the works that will allow you to stream audio from any application to remote speakers connected to your Airport Express. Currently, Airport Express only supports streaming music from iTunes.

The Slipstream application will essentially make your remote stereo system "source agnostic," which will be a boon to anyone with a decent media library in RealPlayer or Windows Media formats. I could see bedroom producers loving this app, as well – load up a mixdown in Pro Tools or Ableton Live and beam it to your stereo speakers to quickly test your track outside the studio. Or, spend $20 on this app instead of shelling out for a set of desktop speakers, and pipe all your system sounds through your stereo.

Look for this handy little audio utility to be released early next year.
