Abstract

3D Audio Technologies include whole signal processing steps from acquisition to reproduction through encoding and transmitting technologies. However, there is a certain difference on adapted technologies according to audio presentation environments, because the presentation environment is the last step to provide 3D audio th listeners. In this paper, we describe variable 3D audio technologies to adapt variable audio presentation environments for consuming music contents.

3차원 오디오 기술은 3차원 오디오를 녹음하는 기술에서 부호화, 전송, 재현에 이르기까지 오디오 신호처리 과정을 포함한다. 하지만 오디오 신호를 재생하는 단말의 환경이 궁극적으로 3차원 오디오를 청취자에게 제공하는 마지막 단계가 되므로 재생환경에 따라서 적용되는 기술에 차이가 있다. 본 논문에서는 음악 콘텐츠를 소비하는 다양한 재생 단말에서 현실감을 증대시키기 위해 적용되는 3차원 오디오 기술의 연구동향을 살펴본다.
