The THX Deep Note is changing and it can be heard here first. The iconic audio track has long proceeded movies certified by THX and features the now familiar crescendo that showcases the movie’s audio capability. This time around THX built the intro to feature 4k video as much as audio as it will be available to theaters that are THX Certified Cinema partners. To make the trailer immersive online, THX utilized its THX Spatial Audio post-production mixing tools that enables online users to experience the multidimensional sound using headphones.
