Reader Question: What is Virtual Surround Sound?

Virtual Surround Sound is an audio system that uses only two speakers to create the illusion of multiple speakers in a surround sound system. Virtual Surround Sound (VSS) uses psychoacoustics to literally trick the ear into believing there is sound coming from a place where there are no speakers. Some VSS systems use a technology known as head related transfer function, which uses sophisticated techniques to fool the ear. Others reflect sound off the walls in the room to create the illusion of surround sound speakers. A 2.1 channel system uses Virtual Surround Sound to create multichannel surround sound from only two speakers and a subwoofer.
