Established in June 2021 as Sanrokumaru Studio, a studio specializing in immersive audio in Minami Aoyama, Tokyo.
We established a studio specializing in immersive audio, which is considered difficult to install, with the technical cooperation of Sony Corporation, Generec Japan, Syntax Japan, MI Seven Japan, and Media Integration, and achieved an appropriate monitor speaker environment. . We have also built equipment routing that supports distributed processing to smoothly produce immersive audio content.
