Deep-Tech Expert in Innovative Acoustic Technologies with various solution services.



President, CEO of Evixar Inc.

We Evixar are the engineer groups who work in research and development in the acoustic engineering field.

We provide an Automatic Content Recognition technology “Evixar ACR” that identifies and analyzes sound content.
It offers ACR technology and systems are provided in a software development kit form that provides access to a library of software that helps the users to develop content recognition applications and utilities. Our technology is applied second screen services, interactive TV systems, broadcast monitoring, subtitle casting, audience measurement, copyright filtering.

And we provide an Acoustic Communication solution “Another Track(R)” that is acoustic communication technology making use of “watermark” audio signals in a frequency range inaudible to the human ear. Emanating from speakers in stadiums, theaters and other such venues, these signals are recognized by smart devices, such as smartphones or wearables. They control the output of the multi-language text or AR display on the devices, timed to the progress of the play or other event taking place in the venue.
The text or AR display occurs within 0.1 seconds, enabling real-time distribution in theaters or other live venues. Since data can be delivered even in an environment lacking electric waves, or to devices in airplane mode, and without the need for special audio equipment, the technology is readily implemented in theaters. Adding, our technologies have been successfully applied to television, motion pictures, theaters, and disaster prevention/mitigation, among other fields.
Another Track(R)” is a proprietary acoustic communication solution developed by Evixar and is comprised of several patents, both granted and pending.

HELLO! MOVIE – The De Facto Standard in the Japanese Theatrical Market –


In 2015, the PoC (Proof of Concept) project to study the ideal viewing environment for low vision and hearing-impaired audiences at the movie theatres was launched. The PoC was funded and conducted by the various Japanese government ministries (the Ministry of Economy, Trade and Industry among others) along with the major theatrical distributors.
In the study, the following technical requirements were identified:
– The app must work properly in any movie theatre environment across the nation “as is” (meaning with no investment of any additional infrastructure, equipment, staffing, etc.)
– The system must work with consumer smartphones.
– The app must be user-friendly.
– The app must function properly when the smartphones are in airplane mode, with all signal transmissions disabled (not capable to receive calls or text messages)

The parties involved in the study found Evixar’s technology (acoustic synchronization system) met their published criteria and in 2020, the commercial use of Evixar’s app HELLO! MOVIE began. The app has become the only format in the country and is now a de facto standard of accessibility devices.
Today, all major film distributors in Japan (Shochiku, Toho, Toei and Kadokawa) as well as the nation’s trade associations, such as MPAJ (equivalent of MPAA) and NATO-JAPAN have adopted Evixar’s "HELLO! MOVIE" app (coupled with special caption projection glasses) as their official device for low vision and hearing-impaired audiences. As for Hollywood studios, Warner Brothers and Sony Pictures have adopted Evixar’s system for the titles acquired in Japan.
We are now applying "HELLO! MOVIE" to the global market, as the new standard for visual and hearing accessibility experience.

EAF - Evixar Audio Forensics

DALL·E 2024-03-08 16.02.14 - Modify the image by adding visual cues that suggest the presence of sound coming from the television, without including actual text on the screen. ShoEvixar has developed a content protection service called EAF (Evixar Audio Forensics) that uses a special sound embedded with encrypted data (watermark sound) and fingerprinting technology for sound sources stored in a database, and has begun recruiting participants for a trial program. It is scheduled to start offering in January 2024.

This will prevent the misuse of deepfake (human image synthesis) videos generated by AI (artificial intelligence). Promoting the development of technology that can identify deepfakes and creating international rules for checking the safety of new services before they are released are major topics on the agenda of the Group of Seven developed countries (G7). Evixar's acoustic communication technology has been patented in Japan, the United States, China, and South Korea, and we will cooperate with the Japanese government to strengthen content protection. In principle, the trial program is provided free of charge, and the price for the commercial stage has not yet been determined.


Why dig deeper into the “Acoustic Technology”?

Why do we delve into the field of “Acoustic”? It is because no matter how much time passes, Acoustic always is a part of our five senses, and that it is our social mission to develop technology in the field of acoustics and uncover the needs for better use of “Acoustic Tech”.
