Dirac Dimensions

Sound field synthesis

Exclusively for automotive and accessible only to the most advanced sound system platforms, Dirac Dimensions™ uses a single customization step to expand the space inside the car, replacing the actual loudspeakers with virtual ones placed in a listening room of your own design. Practicalities, such as up-mixing, setting of relative gains and delays, and acoustical tuning are all integrated into one single customization step: All available physical loudspeakers contribute, in a way impossible to calculate without advanced multi-dimensional acoustical modeling and mathematical optimization, to create the perfect Stereo or 5.1 experiences for all occupants in the car.

With Dirac Dimensions™, Dirac Research again takes car sound optimization to a new paradigm of performance and fidelity. Like a perfect law of nature, it unites all aspects of physical reality into a single model that explains, predicts, and lets us control what we experience.
