While quad was being developed, Dolby Labs was becoming very successful with tape noise reduction systems.

Quad failed to catch on and quickly died. So quad, as it was called, was born, which used four speakers: left and right speakers in front of the listener as in conventional stereo and left and right speakers behind the listener to create the sensation of being 'surrounded by sound'. In the late 1920s and early 1930s, researchers, noting that people listened to sound through one speaker but had two ears, began developing what came to be known as stereo.ДЄround the early 1970s, some people like Ben Baur of CBS, and Peter Scheiber, an independent consultant in Bloomington, Ind., mused that stereo was great, but everything seemed to be coming from in front of and between the two speakers. It turns Dolby Digital's 5.1-channel output into the two virtual surround channels.

The key lies in a so-called virtualizer, developed by companies such as SRS Labs, Spatializer, and Qsound. They can create a very realistic surround sound field from only two speakers placed in front, to the left and right, of the listener, as found in standard stereo systems. Virtual surround sound systems mimic actual surround sound by exploiting the way that the auditory system perceives the direction from which a sound is coming. Virtual surround, which needs only two speakers to create a surround sound image, was the answer to both Dolby's and the consumer's problems. But the company recognized that an alternative to complex multispeaker systems would be required if it wanted to expand the appeal and hence the market of the system, which uses a five-speaker plus subwoofer system to deliver surround sound. Virtual surround systems revert to two speakers but add signal processing to create phantom speakers.Дolby Laboratories Inc., San Francisco, developed what is now the most prevalent system for delivering 5.1 surround to the home, namely, Dolby Digital.

Today's 5.1 home-surround systems are like those used in movie theaters, delivering five audio channels through traditional speakers plus a bandwidth-limited channel through a subwoofer. Quad, in the 1970s, was the first attempt to surround a listener with sound. Learn more в†’Д®volution of Home Audio: Stereo in the late 1920s and early 1930s relied on two speakers.
