Dolby® Virtual Speaker delivers a full surround sound experience from two stereo speakers.

Creates a realistic illusion of a 5.1-channel surround sound system

Works with any pair of stereo speakers

Offers high sound quality and long-term listening comfort

Dolby Virtual Speaker is a highly sophisticated, reference-quality virtual technology that delivers a full, realistic, and natural surround sound experience from just two stereo speakers.

Dolby Virtual Speaker gives listeners the feeling of sound coming from all around them. It works with any material in any format, from 5.1-channel Blu-ray Disc™ and DVD movies, music CDs, MP3 files, video games, and broadcast programming.

Typical surround systems have five main speakers, plus an optional subwoofer. Generally, the Left, Center, and Right channels are reproduced by speakers across the front of the listening area, while the surround effects are reproduced by two additional speakers at the sides or rear.

Dolby Virtual Speaker creates the same effect through a pair of stereo speakers, as if the audio was reproduced by a perfectly set up 5.1-channel system.

Dolby Virtual Speaker delivers reference-quality, highly natural surround sound and does not create listener fatigue. In fact, it is designed for long-term listening enjoyment.

Why Dolby

Dolby Virtual Speaker adds meaningful value to a PC, enabling any PC with built-in stereo speakers or a stereo audio output to deliver a surround sound experience.

Laptop users can enjoy virtual surround sound just about anywhere. For stationary PC setups (laptop or desktop), Dolby Virtual Speaker also delivers the surround experience through external speakers, including those built in to some displays.

Dolby Virtual Speaker works with any PC multichannel audio source, and with any PC stereo source when integrated with Dolby Pro Logic® II or Dolby Pro Logic IIx decoding.

Dolby Virtual Speaker technology uses a powerful and proprietary room-modeling algorithm based on head-related transfer functions, the spectral cues of direction, distance, and elevation that influence how we hear the spatial properties of a sound.

All of this information is contained in sonic signatures. The Dolby Virtual Speaker algorithm duplicates the multiple, complex sonic signatures of a 5.1-channel system in their entirety, from initial impulse to final decay, including the reflections that naturally occur in a room environment.

Additionally, crosstalk cancellation helps ensure accurate reproduction of the surround cues from each virtual surround speaker—vital to maintaining the integrity and perceived directionality of the virtual surround image.
