WHAT IS 3D SOUND TECHNOLOGY

In films furnished with cutting-edge encompass sound frameworks, watchers will want to follow the development of the sound source, at this point not in two aspects, but three-layered space. All the more as of late, we have seen sound system film enter the universe of business and home theaters, and presently super top quality 4K video is in line.

The sound doesn’t linger behind the picture: 3D Audio has come to the home theater, the total sound climate of the watcher – in the flat plane, yet in addition in the third aspect. In English, the term vivid is utilized for this.

Voice of God and other sound channels

The Auro-3D arrangement was presented in May 2006 by the Belgian organization Galaxy Studios. The principal standard film recorded in this organization was the 2012 film Red Tails by George Lucas. The crucial contrast between Auro-3D and the Dolby Surround EX and DTS organizes that won around then was that, notwithstanding the customary 7.1 diverts situated in the similar plane, the designers proposed utilizing the third aspect – that is, putting speaker frameworks (ACs) around the audience, yet in addition on top, with a second “layer”, at a point of 30 degrees to the front speakers and encompass channels.

Further improvement of the arrangement prompted the presence of another “layer” – over the tops of the audience members, which was emblematically called the voice of (“God’s voice”). The greatest number of channels (not to be mistaken for the number of speakers) arrived at 13.1, that is to say, truth be told, it turned out to be two times as numerous as in the then utilized 7.1 and 6.1 organizations. The presentation of the upper channels made it conceivable to all the more precisely convey various occasions in the film’s soundtrack, like the entry of items over the crowd (the commotion of a helicopter or a stream contender), environmental impacts (yelling wind, thunder).

Assuming the roof is too low, the acoustics will be excessively near the watcher. For this situation, Dolby suggests utilizing exceptional speakers that work “truth be told” from the roof – as per the organization, the outcome will be better.

Object approach

The most established player in the film sound industry, Dolby Laboratories, utilizes two “layers” of speakers in its new Dolby Atoms design. The first is situated around the audience as per the traditional plan, and the second on the roof – two by two on the left and right. Be that as it may, in particular – an in a general sense new way to deal with blending soundtracks. Rather than the typical channel-by-channel blending, the studio utilizes the “object” recording technique.

The chief works with sound documents, showing the spot in three-layered space, where these sounds ought to be played from, when and at what volume. For instance, if it is important to imitate the clamor of a moving vehicle, the chief shows the hour of appearance, the volume level, the direction of development, the spot, and the time when the “object” stops.

Also, sound doesn’t get from the studio to the film as recorded tracks, yet as a bunch of sound documents. This data is handled by the processor, which ascertains the soundtrack of the film progressively each time, considering the number of speakers in the corridor, their sort, and area.

Because of exact adjustment, there is no reference to any “ordinary” number of channels, and you can involve an alternate number of speakers in various lobbies (every lobby is aligned and arranged independently) – the actual processor will ascertain how and where to send the sound to get the ideal sound scene. The most extreme number of all the while handled sound “objects” is 128, and the quantity of at the same time upheld autonomous speakers depends on 64.

Dolby isn’t attached to a particular number of sound channels.

The sound picture is shaped by the processor continuously from “objects” and as per the “program” ordered by the sound designer of the film and its best example can be seen in slotroma game. Simultaneously, the processor considers the specific area of the acoustic frameworks, their sort, and number – this is pre-enrolled in the settings while adjusting every specific room. Valid, how to execute such a methodology in a home venue isn’t yet totally clear.

Experts and novices

Following the first experience with business films, both 3D sound configurations started to make advances into the home market. Auro-3D began a little before, a few makers of home gadgets presented the main processors and recipients with design support in mid-2014. Dolby Laboratories was not long in coming, and in mid-September, last year, introduced an entirely reasonable arrangement in light of modest collectors.

Moreover, toward the start of 2015, another central part, the American organization DTS, declared its 3D sound configuration – DTS: X (which is known up to this point just that it, similar to Dolby is object-situated and will be upheld by numerous purchaser gadgets makers).
