You might have heard about them, haven’t you? And you are probably wondering what they are and what they really mean. So, let us explain a little bit more.

Professional home cinema sound systems are available in multiple standards, the most well-known and supported by most high-end home audio systems being Dolby Atmos, DTS and Auro Technologies.

In coming posts we will give you more details about Dolby and Auro, but let’s start with DTS and specifically DTS:X and immersive sound.

DTS

DTS (Digital Theatre System), currently owned by Datasat, is a series of multichannel audio technologies. From the very beginning, the company was specialized in digital immersive sound standards. Founded by Terry Beard, this audio engineer got in touch with Spielberg for the audition and remastering of the film Close Encounters of the Third Kind… He selected DTS sound for his next film, Jurassic Park.

The most common configuration is a 5.1 channel system, 3 screen channels, 2 surround channels plus a special low-frequency channel for the subwoofer.

In 2009, DTS became Datasat Digital Entertainment and the company is a leader in providing digital cinema technology to motion picture exhibitors and distributors.

This system has changed a lot since the initial hard disc synchronized with the image through a time code which was used only in professional cinema to the current digital algorithm. This is due to the business changes that supported it. It is currently the base of the Barco Auro system.

Inmersive sound uses height or presence channels to create a dome of sound taking the multichannel surround experience to a whole new level. There are three different formats on the market: Auro 3D, Dolby Atmos and DTS:X.

DTS:X was first announced in 2015 at the CES (Consumer Electronics Show) and it’s been developing since then. Similar to Auro 3-D and Atmos can only operate on equipment endowed with special hardware. DTS:X appeared in August 15 in commercial theatres with movies such as Sicario and The Hunger Games . American Ultra, Crimson Peak, Ex Machina and the Last Witch Hunter are some of the Blu-Ray releases.

We will give you more info about Auro 3-D and Atmos in coming posts.
