Abstract
Although virtual reality technology may not be deemed as having a satisfactory quality for all users, it tends to incite interest because of the expectation that the technology can allow one to experience something that they may never experience in real life. The most important aspect of this indirect experience is the provision of immersive 3D audio and video, which interacts naturally with every action of the user. The immersive audio faithfully reproduces an acoustic scene in a space corresponding to the position and movement of the listener, and this technology is also called spatial audio. In this paper, we briefly introduce the trend of spatial audio technology in view of acquisition, analysis, reproduction, and the concept of MPEG-I audio standard technology, which is being promoted for spatial audio services.
