What is Dolby Atmos?

It is a sound format that delivers a supported soundtrack to the conventional surround speakers dotted around the cinema or room at home, including the subwoofer(s), and also to speakers in the ceiling to give extra height to the soundscape.

Dolby Atmos Benefits

What is Auro 3D?

Auro-3D is an immersive 3D audio format. It is designed along three layers of sound (surround, height and overhead ceiling), building on the single horizontal layer used in the 5.1 sound format. Auro-3D creates a spatial sound field by adding a height layer around the audience on top of the traditional 2D surround sound system. This additional layer reveals both localized sounds and height reflections complementing the sounds that exist in the lower surround layer. The height information that is captured during recording is mixed into a standard 5.1 surround PCM carrier, and during playback the Auro-3D decoder extracts the originally recorded height channels from this stream.
The Auro-3D technology consists of the Auro-3D Engine and a Creative Tool Suite. The engine comprises the Auro-Codec and the Auro-Matic upmixing algorithm to convert legacy content into the Auro-3D format. The Creative Tool Suite is a set of plugins that can be used to create native immersive 3D audio content. Auro-3D is fully compatible with all existing production processes and theatre systems, and the format also offers a host of compatibility features such as Single Inventory Distribution (multiple formats are combined in one PCM carrier) and full DCI compliancy.

Auro 11.1

Auro 11.1 is one of the cinematic speaker layouts of the Auro-3D format. The Auro 11.1 cinema sound format adds two additional layers of sound to the existing 5.1 surround sound layer. The Auro 11.1 format incorporates a unique height and overhead channel which allow for natural lifelike sound with sound waves coming from every direction, just like they do in real life. In this way, Auro 11.1 creates the most realistic and natural immersive audio experience.

What is DTS:X?

An object-based surround sound technology that is a successor to DTS HD and a rival to Dolby Atmos.

For each speaker, DTS:X allows the "location" (direction from the listener) of "objects" (audio tracks) to be specified as polar coordinates. The audio processor is then responsible for dynamically rendering sound output depending on the number and position of speakers available. Dolby Atmos uses a similar technique, although the speaker layout employed by cinema DTS:X is the sum of Dolby Atmos and Auro-3D. The layout showcased at AMC Burbank theatre number 8 has a standard eight channel base layer, a five channel height layer on top of the base layer (on the front and side walls) and three rows of speakers on the ceiling. The surround arrays are bass managed by woofers suspended from the ceiling. A first public demonstration was performed at CES 2015 on a Trinnov Altitude32 processor.
