All about Surround Sound System
Surround sound is basically a sound reproduction technique to enhance its quality and make the hearing experience better. Today, you would find the markets filled with surround sound technology audio and audio-visual devices. It is a technique that was first introduced in the 1969 as the quadraphonic technology but with time it has developed a lot. The basic pattern followed in this is that sound is produced from a 360 degree radius in a 2 dimensional plane in opposition to the screen. It also has a feature of sweet spot, i.e., the spot where the audio sounds the best. The entire set up of surround sound is achieved by several separate audio channels transmitted to an arrangement of loudspeakers.
Surround sound in its very fundamental form involves arrangement of speakers, 2 out of which are placed on the front, 2 on either sides and one at front of a central listening point. This basic five set of speakers can be used to create surround sound effect very easily. But as the number of speakers increase the technique of producing surround sound also becomes a little more complex. The addition of a subwoofer to the basic five speaker arrangement of the surround sound is the 5.1 format. Most of the home theatre technologies use the same technique for surround sound and even Blue-ray discs have the same. Till date, it is considered by many as the standard of surround sound. There is also a 6.1 version of surround sound where the audio information is encoded in matrix format for the left and right surround speakers. It is a technically higher version of surround sound. The 7.1 version has discrete stereo information for all the seven speakers and it was made possible by the massive storage space of Blue-ray. Generally there are two versions of 7.1; one is the compressed version and the other is the true HD version, with no compression.
The various surround sound techniques can be employed to get the desired audio effects.
