A piece of technology from sister brand NAD generates additional signals for the rear surround speakers – within a home theater group configured in the BluOS® App – from the stereo channels (Dolby recordings are always decoded as intended). This is intended to create a room-filling, natural surround sound impression when playing stereo sources.
The Stereo Surround Codec exclusively uses the natural spatial atmosphere that is present in almost all well-produced stereo recordings. It is supposed to add no artificial room ambience or other sonic elements, which is why the Bluesound Stereo Surround mode aims to stay much closer to the original recording than most other home entertainment surround options.
Matt Simmonds, Bluesound Product Manager, states: "More and more customers are looking for high-quality, wireless, surround sound options for everyday listening. Using Stereo Surround provides customers a subtle but highly natural and believable ambience from the surround channels, creating an immersive experience even when playing two-channel content".
