Real-time 3D sound system with head-tracking

Established for more than one century, the communication system continues to evolve toward simulating immersive environments that emulate reality. In particular, the concepts of augmented reality (AR) and virtual reality (VR) have recently became increasingly popular with large corporations, such as...

description Established for more than one century, the communication system continues to evolve toward simulating immersive environments that emulate reality.
