7.1 Surround Sound Speaker

By Rachman ray

It is hard to speak without mentioning Dolby in some way shape or form when we mention computer speakers. Dolby 7.1 is one of some great sound reproduction methods that Dolby has developed.  With the naming scheme of the two numbers separated by a decimal point Dolby has come up.

The number of speakers is represented by the first digit, in this case seven speakers. The one channel for the subwoofer or the bass channel represented by the second digit. Dolby is used on entertainment systems, televisions, computers and Dolby is the brand name for the digital surround sound.

7.1 computer speakers use the seven speakers and place the sounds in the right place. To place the sound where it is supposed to be is the point of surround sound. Because it has appeared with the latest HD devices such as Play station 3 and HD Televisions, the 7.1 system is sometimes called HD sound but Dolby were always going to develop new sound systems regardless of HD technology.

The 7.1 computer speakers work by decoding all seven channels as with other Dolby systems from just the left and right audio channels. The 7.1 speakers soon will be phasing the standard 5.1 channels which is currently the most popular speakers because the 7.1 offer a much better sound depth . It’s quite difficult in order to take the two audio signals, left and right, and turn them into surround sound.

Dolby are clever bunch, they needed to integrate the new surround sound into the existing technology in order for their system to be accepted and so they developed it to fit with existing two channel systems. Requires some pretty hefty mathematical technology to understand how the system works.

No signal processing required, the standard left and right channels are extracted as they are.The center channel between the left and right is obviously the difference. The back speakers are require the signals to be phase shifted from the front channels by 90 degrees and it’s little more complicated. It definitely makes a difference and the sound dept is unbelievable if added of  an extra two speakers. The sound appears exactly where it is supposed to be.
