Given expectations that Microsoft's Windows 8 operating system will wind up in embedded products and tablets, x86 and ARM alike, it's good news that the firm has announced it will be supporting playback of Dolby Digital Plus encoded content on both hardware architectures.
Dolby Digital Plus brings with it support for the standard Dolby Digital spec, though also enables bit rates of up to 6Mbps and 7.1 channel audio, as opposed to the 640kbps and 5.1 channels found in the original standard, along with a greater choice of output mediums.
On ARM tablets especially, it could be a while before we see third-party codec packs with strong performance and error-free playback offered as an alternative. "Widespread availability of Dolby Digital Plus on Windows 8 will enable more people to enjoy cinematic sound anytime, anywhere, and on any device," announced Dolby executive vice president of sales, Ramzi Haidamus.
Having the Dolby Digital Plus brand attached to any shipping Windows 8 device would no doubt be a valuable selling point against Apple and Google alternatives.
