Summary:
During the past decade, there has been a rapid development of audio and video technologies in many areas. Furthermore, the commencement of commercialization of 5G service ultimately comes down to the inherent belief that smartphone VR is going to be the primary driver in the market. Here, 3D audio technology which is mainly used to make computer games more realistic will soon be applied to the next generation of mobile devices and expected to offer a more expansive experience than its visual counterpart. This paper introduces the 3D sound technologies covering algorithms and systems for modeling based on multichannel methods and physics-based geometric algorithms. Also, it introduces an audio rendering pipeline to a scene graph-based virtual reality system and a hardware architecture to model sound propagation.
