With the development of digital cinema, audiences have higher and higher requirements for the quality of cinema presentation. The high-end giant screen also attracted more audiences. The high-quality images with the high brightness, high dynamic range (HDR) and wide color gamut (WCG) technology and the extreme immersive audio experience make the audience truly feel the charm of technology behind the art of film.

Topic I: Immersive Audio is DCI / SMPTE Standard

In 2015, SMPTE began the research work on immersive audio standards for digital cinema, which covers all aspects of the digital cinema industry such as the content provider, equipment provider, and film distributor. Until now, the key immersive audio standards have been released. The birth of these standards means the arrival of large-scale industrialization, and immersive audio technology has become the general trend.

As a member of the SMPTE Immersive Audio Working Group, LEONIS has been involved in the discussion and the development of standards. HOLOSOUND immersive audio technology was born with the formation of international standards. At present, Dolby ATMOS, LEONIS HOLOSOUND and DTS:X have formed a situation of tripartite confrontation internationally.

Topic II: HOLOSOUND, Extreme Immersive Audio Experience

HOLOSOUND is a DCI / SMPTE-compliant immersive audio technology independently developed by LEONIS.

Based on the Channel-Base Sound (CBS) technology and the Object-Based Sound (OBS) technology, it also supports Scene-based Sound (SBS) technology (including Scene Recording and Scene Playback). It can support a maximum of 256-channel output, which is 4-16 times that of other immersive audio technologies.

On October 11, 2018, HOLOSOUND has passed the certification of the industry experts jointly organized by China Film Distribution and Exhibition Association (CFDEA) and China Film Science and Technology Research Institute (CRIFST). The result shows that HOLOSOUND is comparable to and compatible with another immersive audio technology widely used in the market. In addition, HOLOSOUND has unique advantages in sound scene technology and audio immersive index.

In order to meet the needs of different theater hall structures, LEONIS CINEMA, the world's leading immersive audio technology provider, has launched a number of HOLOSOUND immersive audio processors in recent years, including DCAP-OBIA, DCAP-OBIA-E, DCAP-IAE, DCAP-IA, etc.

There are 96 main speakers and surround speakers in this cinema, only HOLOSOUND can take on this major task.
