Sony Corp subsidiary Sony Dynamic Digital Sound said it will offer a new 35mm digital sound technology that offers eight discrete channels, developed in a collaborative effort between the company’s engineers in Japan and at its Culver City, California research lab; Sony plans to install Sony Dynamic Digital Sound at 150 of its cinemas in time for what it calls the Christmas movie-going season and in all 1,000 of its cinemas eventually; the key feature of Sony’s system is the integration of the discrete channels into the film soundtrack where competing systems are recorded to a separate compact disk and must be synchronised to match the picture – just as in the very first talkies, which used shellac disks for sound; AMC Entertainment Inc will install the system in 1,700 of its auditoria at $13,800 a time.
