Virtual reality means artificial reality which can be realized through five senses. Observation can be possible as virtual reality leads to that human being are at tele-existence. In addition, human beings can have teleconferences and do cooperative work in the virtual reality environment. If we hear 3D sound in the space of virtual reality, we can almost realize such operations. 3D sound is essential to realize virtual reality. A variety of factors need to be considered such as intensity of sound delivered to ears, frequency spectrum, phase of sound and auditorial senses to implement 3D sound. In this paper, the information of the software can be transferred to the hardware, the hardware can be controlled, then 3D sound for teleconferences can be implemented in the virtual space, using Head Related Transfer Function (HRTF). Furthermore, it can also apply to 3D games.

오늘날 사운드 컨텐츠는 DVD의 등장으로 CD음질이상인 3D서라운드 오디오를 기본으로 하는 추세이다. 이에 맞춰 컨텐츠 개발환경이 보다 진보되어야하며, 이러한 시스템의 효과적인 응용이 필요하다. 게임 및 멀티미디어 사운드컨텐츠 제작에 필수적인 시스템 장치인 Sound/Audio Card의 효과적인 이용을 위한 개선방법과 3D사운드제작에 필요한 관련지식과 제작 Tool의 사용방법과 응용을 연구하였다.
