What is Virtual Surround?
Normal surround systems employ at least four speakers to create a spatial effect. Modern sound cards can create a similar effect with two speakers using advanced algorithms that can process the multichannel audio source to identify the “spatialness” and create an approximation by altering the stereo output. This is called Virtual Surround. While the totality of the “surroundness” can be achieved, the fidelity that is achieved with surround speakers cannot be duplicated. The reverse of the process is also seen, wherein a normal stereo sound source is processed and surround sound channels suited for a 4.1 or higher speaker system is generated.
