Dolby Surround 7.1 outed with improved rear 3D sound placement

Dolby have announced Dolby Surround 7.1, an 8-channel surround sound audio system that’s intended to better support both traditional 2D and newer 3D content. Integral to the new system is the introduction of two new audio zones – Back Surround Left and Back Surround Right – which, in tandem with the existing front two zones, should make for more impressive 360-degree surround effects.

Unlike existing 7.1 systems, which use two rear speakers but each fed with the same channel, Dolby’s new setup will have two different channels for each. For movie makers like Disney and Pixar, who Dolby have partnered with to demonstrate Dolby Surround 7.1, it means an increased ability to position sound in theatres. Of course, we’ll have to wait for those theatres to actually roll it out first; no word on how expensive the upgrade might be, or what sort of timescale we’re looking at.
