What is DTS:X for IAB?

GDC Technology, a world-leading digital cinema solutions provider, and DTS, Inc. are working together to offer DTS:X that supports IAB which is an international immersive audio standard. Both DTS:X and IAB are object-based immersive sound formats that accurately conveys the fluid movement of sound to create a richer entertainment soundscape by moving sound objects to and through specific locations within – in front of, behind, above, and beside the audience, precisely where the mixer placed them.


GDC’s integrated media block supports both the DTS:X and IAB immersive audio formats, and the latter represents a major milestone to deliver a single interoperable audio format. IAB allows motion picture studios to efficiently distribute immersive audio content to the DTS:X screens worldwide-exactly as the filmmakers intended.
