Combining Dolby Surround Sound Capturing with Nokia Rich Recording, all of your videos will document exactly what you hear. Play it back and you’ll experience true surround sound in 5.1 Dolby Digital Plus format.
The Nokia Lumia 1520, Lumia Icon and the new Lumia 930 will also be able to project content wirelessly to Miracast-enabled screens, TVs, and projectors.
All of this will come to your Lumia smartphone running on Windows Phone 8 in an update package called Lumia Cyan-starting this summer.
Unfortunately, one needs to wait till Summer for Lumia Cyan to hit devices.
