Dolby Virtual Speaker transforms stereo (two-channel) and 5.1-channel content into virtual surround sound that you can enjoy over just two speakers.
Using only two speakers, Dolby® Virtual Speaker gives you the complete sonic spectrum and dynamic audio of a 5.1-channel speaker system.
Because Dolby Virtual Speaker works with any pair of speakers, you can experience surround sound even in small spaces, and with a variety of devices—including TVs, A/V receivers, and sound bars.
Choose from the two surround listening settings, Wide mode and Reference mode, for the Dolby Virtual Speaker option that gives the best possible audio in your unique environment.
Ideal for small spaces, Wide mode broadens the sound image by creating the sense that the two speakers are farther apart than they are in reality.
Reference mode keeps the width of the front sound image the same as the actual distance between the two speakers, so it's better suited for more spacious environments.
Watching a movie in surround sound in a fully equipped 5.1-channel home theater can be incredible. At its best, it puts you in the center of the action and brings out subtleties in the soundtrack that you wouldn't have noticed otherwise. But not every room is large enough for a 5.1 setup, and not every entertainment device supports 5.1 channels of audio. Dolby Virtual Speaker allows you to enjoy realistic 5.1-channel surround sound in just about any room—using as few as two speakers.
A highly sophisticated audio technology, Dolby Virtual Speaker can be found in TVs, A/V receivers, and other entertainment devices. It uses advanced algorithms and room-modeling capabilities to duplicate complex sonic signatures—including reflections—that naturally occur in a 5.1-channel surround sound environment. The result: your living room, bedroom, or dorm room becomes a virtual home theater.
Previous surround sound virtualization approaches often gave listeners a sense of being overloaded by sound after extended listening. Because Dolby Virtual Speaker re-creates all of the acoustic characteristics of multiple speakers in a real environment, there's no sensory overload. Instead, you're wrapped in surround sound, so you can relax and enjoy your music, movies, and TV programs hours longer and in complete comfort.
Whether your content source is two-channel stereo or true 5.1-channel audio, Dolby Virtual Speaker makes it sound better over just two speakers and over a longer period of time.
