Dirac Research believes it has removed a major barrier to a truly immersive AR/VR experience with the introduction of its “Dynamic 3D Audio” AR/VR platform featuring patent-pending dynamic HRTFs (head-related transfer functions) that consider the isolated movements of the head in relation to the human torso. The current industry-standard HRTFs incorrectly assume that the body and head must always move in tandem.
“Simultaneous visual and aural immersion is the linchpin of a true virtual reality experience,” says Dirac Research founder/CEO Dr. Mathias Johansson. “It’s what separates reality, experienced virtually, from an obvious representation of such. Until today, the limitations of the 3D audio technology used in VR/ AR programming have prevented this true immersion from being created, rendering a gaming, entertainment, or educational VR experience that is fundamentally flawed, with too many reminders that true reality exists elsewhere. With Dynamic 3D Audio, these limitations no longer exist. True simultaneous visual and aural immersion is now a certain reality within the virtual experience.”
According to Johansson, Dirac’s Dynamic 3D Audio is comprised of multiple fundamental breakthroughs, the most central being the development of the patent-pending Dynamic HRTFs that consider the isolated movements of the head in relation to the torso. “The failure to accurately reproduce dynamic head movements in virtual reality is one of the reasons why existing 3D sound solutions don’t sound quite realistic,” says Johansson.
The torso-head dilemma isn’t the only immersion limitation resolved by Dirac’s Dynamic 3D Audio platform. HRTFs are a function of how one’s ear perceives a particular sound from a point in space. Height, cranial proportions and ear dimensions, among other factors, all play a role in one’s individualized HRTF. That said, to create a completely immersive 3D audio experience, the industry standard relies on the “individualized” HRTF measurement of each listener—a time-consuming and laborious process that ultimately lacks scalability.
