The Best Guide For Surround Sound

The Best Guide For Surround Sound

The first time surrounded sound available in a home was in the summer of 1969. This was called Quadraphonic sound at that time which appeared in the reel to reel tape. From the basic surround sound 5.1 to the Dolby atmos setups with multiple maintenance speakers. It's a lot to swaddle your head around. There are a lot of types of surround sounds which you should know about but you will have clarity after reading this guide for the best surround sound.

The Speakers

The very basic surround sound involves a stereo front, speakers (left and right) and set surround speakers, which are normally placed just to the sides and behind a central listening place. For the next step, it is involving the addition of the central channel. The speaker which is responsible for the reproduction of dialogues in the movies is the speaker between the left and the right speaker. Thus there are five speakers and the further will added, the basic fiver speaker system is good enough and can be used for getting into the different formats as a springboard.


Matrix simply means encoding the separate sound signal within a stereo source. This approach was for the purpose of early surround sound formats like Dolby Pro Logic and Dolby surround. And it was motivated in the part of the restricted space for the discrete information. It is like VHS tape an early audio-video media.

Dolby's pro logic

It was developed to encode the signals in the left and the right channels by using the matrix process. Dolby was competent to permit home lossless audio machines to decrypt two extra lanes of sound from media like VHS tapes, which fed the center lanes and surround sound speakers with audio. Because of the restricted space, matrixed surround signals arrived with some restrictions. The surround channels in main Pro Logic were not in stereo and had limited bandwidth. That means that each speaker played similar stuff and the sound didn’t comprise many bass or treble data.

Dolphy digital 5.1

After the release of obvious and Current Danger on LaserDisc, the initial Dolby Digital surround sound came for home theaters. The format of Dolphy digital 5.1 improved in pro logic and allowed the stereo surround speakers which could provide the higher bandwidth sound. One of the benefits of LaserDisc (LD) is that it gave a lot more storage space than the VHS tape. Dolby took advantage of this and formulated AC-3, which is now known as Dolby digital. All of the data in the Dolby digital 5.1 is encoded for every channel. Which means there is no requirement for the matrix process.

DTS: the rival

Dolby more or less ruled the surround-sound terrain for years. Then, in 1993, DTS (Digital Theater Systems) arrived ahead, giving its own digital surround-sound blending assistance for movie creation, first appearing in cinemas with Jurassic Park. The technology finally trickled down to LD and DVD but was originally available on a very restricted choice of discs. DTS uses an increased bit rate and, therefore, transmits more audio information. Think of it as identical to the distinction between hearing to 256kbps and 320kbps MP3 file. The quality discrepancy is obvious, but according to some, inconsequential.

The Pro Logic 2

Pro Logic II is mostly like its early Pro Logic ancestor in that it can create 5.1 surround sound out of a stereo basis. The discrepancy is Pro Logic II gives stereo surround data. This processing mode is normally used when watching non-HD TV tracks with a stereo-only lossless audio blend.

Pro logic 2x

Pro Logic 2x is also a module we mentioned that can take a 5.1 surround mix and enlarge it to 6.1 or 7.1. Pro Logic 2x is subdivided into a film, song and game mode.

Pro logic 2z

Pro Logic 2z enables the expansion of two front height speakers that are positioned above and between the central stereo speakers. This form of matrix processing tries to expand more depth and space to a soundtrack by outputting tones from a whole new direction in the room. Since 2z processing can be committed with a 7.1 soundtrack, the resultant format could be named 9.1.

3d surround sound system

The latest and tremendous growth in surround sound offers not only discrete audio for height channels but also a new means for sound creators to blend sound for the most precise, hemispheric immersion in the period. The name object-based/3d is assigned because, with this discrete third dimension, the lossless audio blenders working on a movie can illustrate individual tone objects, such as a buzzing bee or a helicopter, in 3D space relatively being restricted by a common channel configuration.

Increasing the discrete lanes for ceiling-mounted or ceiling-facing speakers in A/V recipients at home, height channels are now depicted as their own different entities, directing to an additional number used to depict home surround lanes. A 5.1.2 policy, for illustration, would feature the formal five lanes and a subwoofer, but would also have two additional speakers expanding height data in stereo at the front. A 5.1.4 system would expand four extra height channels to 5.1, comprising two at the front, two at the bottom, and so on.

7.2, 9.2 or 11.2

5.1, 7.1, and all others refer to the L.F.E (low-frequency effects) tone in a surround soundtrack, which is handled by a subwoofer. Adding .2 clearly implies that a receiver has two subwoofer outcomes. Both harmonies put out the same data since, as far as Dolby and DTS concerned, there is only a subwoofer path. Since A/V receiver factories want to effortlessly market the extra subwoofer outcome, the belief of using .2 was accepted.

There are a lot of types of surround sound if you have read this guide carefully, you can easily select the best surround sound for yourself.
