What is the dolby® virtual speaker?

The

Dolby® virtual speaker creates a spatial sound experience above stereo speakers and creates a virtual speaker system 5.1 without additional speakers, costs, wires or problems. These proprietary technological processes encoded multi -channel sound accompaniment, rewriting and recoding for output over two speakers without losing the effect of the spatial sound. Seems impossible? Not for creative people in Dolby.

You want to understand how it works, consider a simple sound signature. The speaker is placed several feet (2-3 m) in front of the subject in a typical living room. A tone is emitted from the speaker. Some sound waves reach left and right ears directly at slightly different intervals, but other waves reflect from walls, ceiling and floors, reach ears not only at different intervals, but also at slightly different levels of volume and tone. The brain counts both direct and reflected sound to determine the signal source and get a feeling for the size of the room.

by the sounds of processing that toIt grinds to different intervals, fluctuates in tone, level and other fine properties, ears and brain can be "cheated" into the thinking of sound coming from further than is, or from a certain direction - even from behind.

To achieve the dolby virtual speaker uses sound interference technology or Crosstalk cancellation to maintain strict control over what each ear hears. Sound waves that would spoil the effect or distribute a real signal source are removed from the audio spectrum by each speaker that issues not only its part of the soundtrack, but also reflects the images of the opposite speaker output. This prevents the right ear from hearing things that should not be from the left speaker and vice versa. In this way, the Dolby virtual speaker can create the illusion of sound release, wherever it wants, replicate the spatial sound of 5.1 perception.

Dolby virtual speaker is based on a chip that can be built intoAn entertainment, PC, television, boom or any sound device that has the outputs of the speaker. The receiver can be capable of 5.1 outputs using several speakers or dolby output virtual speaker using only two. Everyone wants the advantage of spatial sound, whether playing, watching television or viewing a movie. Now, everyone, regardless of physical space, budget or other restrictions that could be a impractical system of spatial sound, may have it.

When checking the next PC, DVD player or Virtual Dolby Virtual speaker, also follow the Dolby headphones. It sends virtual spatial sound through your headphone connector and converts any pair of stereo headphones to spatial sound headphones. Dolby's website has sound demonstrations of both technologies.
