This paper proposes a 3-dimensional (3D) voice over IP (VoIP) system for two user groups with the smallest device requirements. It also presents design issues of the system and some experience in implementation of the system. The proposed system requires only a desktop computer with a multi-channel soundcard installed, USB microphones as many as the number of users, and 3D sound rendering system such as 5.1ch or 7.1ch loudspeaker system. It not only enables multiple users to communicate with a remote group using a single desktop computer, but also enriches the voice of each user with 3D spatial effect. Using the system, the participants can hear the voice of remote users through a 3D sound rendering system, as if each remote user speaks at his or her corresponding position. This system can be used for immersive teleconference system
