The ultimate goal in virtual reality (VR) is to achieve complete immersion in terms of audio and video, where background music is typically included to keep users absorbed in a game or 360-video content. This paper explores a multichannel loudspeaker configuration to anchor the background music to the user’s viewpoint in VR. To that end, an evenly-spaced octagonal loudspeaker configuration is implemented in order to anchor the background music using head tracking data. The real-time panning is achieved through Vector-Base Amplitude Panning (VBAP). This paper also describes a demo interface built using the Oculus Rift in Unity and Max/MSP, as proof of concept.
