Technology overview

The technology utilizes a object-based audio approach, which allows sound engineers to pinpoint the exact location of a sound in a three-dimensional space, creating a more immersive experience for the listener. This is achieved through the use of metadata that describes the location and movement of sound objects, such as dialogue, music, and sound effects, in relation to the listener. The technology is compatible with a wide range of devices, including home theaters, cinemas, and virtual reality headsets, such as those developed by Oculus VR and HTC Vive. Companies like Sony, LG, and Samsung have also integrated the technology into their 4K and 8K TVs, while Amazon and Google have incorporated it into their smart speakers and streaming devices.

Development and history

The development of the technology began in the early 2010s, with the first public demonstration taking place at the 2012 Consumer Electronics Show in Las Vegas. The technology was initially developed in collaboration with Disney, Pixar, and DreamWorks Animation, with the first film to be mixed and released in the format being Brave, a Pixar animated film. The technology has since been adopted by many major film studios, including Warner Bros., Universal Pictures, and Paramount Pictures, as well as by streaming services like Hulu and Amazon Prime Video. Notable directors, such as Christopher Nolan and Quentin Tarantino, have also utilized the technology in their films, including Dunkirk and Once Upon a Time in Hollywood.
