HoloSound, the Alternative and Beyond of Dolby ATMOS

HoloSound, the Alternative and Beyond of Dolby ATMOS Date 2018-12-05 Author Original Site . What is HoloSound?

LEONIS Cinema is introducing new Immersive Audio Technology: HoloSound. It offers the perfect combination of sound channels, sound objects and sound scene to create a sound field that enables the continuous movement of sound in three-dimensional space.

. The advantages of HoloSound

Compliant to SMPTE standard (25CSS Standard Suite), HoloSound can support up to 256 speakers, which is 4-16 times larger than other immersive audio technologies. Besides overhead surround speakers and side surround speakers, HoloSound provides speakers underneath the audience a unique and innovative addition. Moreover, it supports point sources to allow driving of individual speakers, not just arrays of speakers.

. HoloSound, Immersive audio authoring and rendering technology

The HoloSound content authoring system MPU (Mastering and Processing Unit) is for post-production, while the HoloSound content rendering system (including Immersive Audio Processor DCAP-OBIA, Immersive Audio Digital to Analog Converter DAC-OBIA, Immersive Audio Digital Surround Power Amplifier LIDSA32, etc.) is for the venue such as a theater, theme park or museum.

In addition to its application in digital cinema, HoloSound also includes HoloSound-VR and HoloSound-Consumer technology that separately applies in the field of virtual reality and personal consumer electronics to comprehensively realize the consumer immersive high-end experience.

. HoloSound vs. ATMOS evaluation by CFDEA

The subjective listening expert evaluation of HoloSound audio system was successfully completed by CRIFST (China Research Institute of Film Science & Technology) in the morning of Oct. 11, 2018. The members of the evaluation expert group are from senior scholars and expert in the cinema audio field. The evaluation was hosted by the China Film Distribution and Exhibition Association (CFDEA), compared the compatibility and the sound effects between the LEONIS HoloSound system and the Dolby ATMOS system.

The result shows that:

[1]LEONIS HoloSound system and Dolby ATMOS system compatible perfectly, it means that the Dolby ATMOS system can renderer the contents of the LEONIS HoloSound system, and the LEONIS HoloSound system can renderer the contents of the Dolby ATMOS system too.

[2]In the point of sound quality, sound orientation, sound continuity, sound level, loudness uniformity and sound effect, LEONIS HoloSound is as excellent as Dolby ATMOS.

.HoloSound, the Alternative and Beyond of DOLBY ATMOS

[1] Same as Dolby

Fully compatible with DCI/SMPTE specification /standard.

[2] Beyond over Dolby ATMOS

(a) Number of speakers supported

HoloSound can support up to 256 speakers, Dolby only support up to 64 speakers;

(b)Unique sound field technology support

Dolby ATMOS only supports channel and object technology, HoloSound also supports sound scene technology (SBS) beside channel and object technology(CBS and OBS).

(c)Audio Immersive Index (AII)

LEONIS innovatively proposed the concept of Audio Immersive Index, which is used to set standards to measure Immersive capability of audio system.

The Audio Immersive Index (AII) of HoloSound is the best of several object-based immersive audio technologies.

. HoloSound ,Immersive Audio Solutions for LED

For Direct View Displays, speakers cannot be placed in back of the screen as in conventional projection-based cinemas. To address this emerging market, LEONIS has launched an immersive audio HoloSound solution named HS-DVD which processes the sound field to give an ideal immersive sound effect for LED theaters and create a perfect audio system for viewers.

. HoloSound AI Design & HoloSound AI Position

Recently, LEONIS HoloSound launched artificial intelligence service HS-AI-Design and HS-AI-Position. HS-AI-Design can accomplish the layout of HoloSound speakers in the theater using artificial intelligence after inputting the structure parameters of the theater. HS-AI-Position can quickly locate the point sound source with accuracy within +/-1 degree (azimuth and pitch angle).

. LEONIS HoloSound Will Shine at CineAsia

CineAsia 2018, as the leading conference and trade exhibition for the film distribution and screening in Asia and the Pacific, will be held in Hong Kong on December 10th -13th, 2018.

According to the official confirmation of the FilmExpoGroup, Dr. Ma Shichao, the founder of LEONIS, will share "HoloSound, the Immersive Audio Authoring and Rendering Technology Conforms to DCI/SMPTE Standard." in the International Day of CineAsia.

Address: Hong Kong Convention & Exhibition Center (HKCEC), Theater 2

Time: Monday, December 10th, 2018, 3:00 pm
