DTS:X Compatible DTS:X is a next-generation object-based surround sound technology that includes height to deliver a fully-immersive listening experience. DTS:X provides listeners the ultimate in flexibility, immersion, and interactivity. Unlike channel-based audio, you will be able to personalize your audio experience. For example, you can turn up JUST the dialog within a mix. DTS:X allows you to customize to your room layout as well as control dialog and dynamic range. Supports Dolby Atmos Up to 5.1.2 Channels With Dolby Atmos, sound comes alive from all directions, including overhead. The format combines a channel-based audio bed with object-oriented sound to place and move specific effects around the room, creating a breathtakingly realistic and captivating sonic atmosphere. Sound designers and artists are free to mix in a 3D space, steering effects through surround channels and adding a seamless overhead dimension with discrete height channels. Additionally, a new Dolby surround up-mixer allows for your current channel-based content (that has not been mixed for Dolby Atmos) to be expanded to fill the flexible speaker layouts of a Dolby Atmos system.
