Simultaneous visual and aural immersion is the linchpin of a true virtual reality experience— yet, until today, the limitations of the 3D audio technology used in VR/ AR programming have prevented this true immersion from being created, rendering a VR experience with too many reminders that true reality exists elsewhere. Using patent-pending dynamic HRTFs and other new technologies featured in Dirac’s Dynamic 3D Audio platform, Dirac VR removes one of the industry’s major barriers to a truly immersive VR/AR experience. You’ll no longer notice you’re wearing a headset.
Groundbreaking Dynamic HRTFs
A major barrier to the truly immersive AR/AR experience is removed with the introduction of Dirac VR, featuring patent-pending dynamic HRTFs (head-related transfer functions) which take into consideration the isolated movements of the head in relation to the human torso.
High-resolution HRTF measurements
The torso-head dilemma isn’t the only immersion limitation resolved by Dirac VR. Existing databases of static HRTFs lack resolution and suffer from measurement noise and errors. These shortcomings of existing HRTFs result in inaccurate positioning of audio sources and sound quality degradations. To create a more immersive audio experience, the current state of the art relies on “individualized” HRTF measurements of each listener — a time-consuming and laborious process which ultimately lacks scalability. Dirac VR utilizes a highly sophisticated HRTF measurement process that, when compared to existing approaches, is exponentially more free from noise and error. And, excitingly, when this measurement process is combined with dynamic HRTFs, the benefits of individualization become virtually immaterial and ultimately obsolete. Most importantly, the combination ensures the reproduction of much more accurate, natural, positional sound without sound coloration—resulting in true immersion for the listener.
Natural and realistic three-dimensional space
In virtual reality, if someone calls out from behind you in a church, with the right audio cues you’ll not only hear the audio coming from that direction, you’ll also recognize that you are in a church (not a bathroom or a long corridor). The reason for this is that each space has its own specific acoustical behaviors that color the sound, helping you identify where you are.
Using a proprietary 3D reverberation engine, Dirac VR realistically renders the critical aspects of a room’s unique acoustics to create a sense of a specific space and distance that mirrors reality. Using the same platform, Dirac engineers have successfully recreated the acoustical behaviors of the Gothenburg Concert Hall from inside a Volvo XC90—the winner of “Best Audio System – over £25,000” at the inaugural Car Tech Awards.
