IMAX Goes Dig­i­tal

NOVO - - IMAX -

In the early 1990s, IMAX be­gan its con­ver­sion to a dig­i­tal en­vi­ron­ment by first con­vert­ing the au­dio to a six chan­nel DTS mix that was stored on CD-ROMs and played along in lock-step with the ana­log video. By the end of the decade, IMAX had adopted its own pro­pri­etary dig­i­tal au­dio stan­dard con­sist­ing of six em­bed­ded tracks that cre­ated a full sur­round sound con­fig­u­ra­tion, which also in­cluded a sep­a­rate speaker be­hind the screen at the top cen­tre to bet­ter lever­age the large screen height.
