Bluesound is actively developing a line of devices running BluOS. One of the new features is the stereo surround mode, which will become available to owners of Pulse Soundbar and Powernode devices with the update to the latest version of BluOS 3.12 (the exact figure has not yet been specified). Also, these devices will be able to integrate with URC and Crestron control systems.
Stereo Surround mode is based on technologies used in the NAD technique: from a 2-channel source signal using special mixing algorithms, it generates a signal for the rear channels. As stated in the description, such a function creates a realistic immersive effect, does not add anything of itself, but only cleverly manages the original signal, due to which it remains closer to the original audio recording than other surround sound emulation algorithms.
The Pulse Soundbar and Powernode can be used to build wireless theaters, and this feature is in demand: According to Matt Simmonds, Bluesound product manager, more and more people are looking for wireless surround sound systems for everyday listening, a feature that creates realistic playback volume. 2-channel content is very important to them.
