Evaluation of Binaural Renderers in Virtual Reality Environments: Platform and Examples

摘要

One of the challenges of virtual reality technology is to provide convincing sensory information to users, to give the illusion of presence within the virtual environment. Audio-visual input combined with self-motion is a step beyond traditional cinematic content, whereby the audio Tenderer must accommodate a limitless number of potential user interactions and movements within an acoustic field. In this e-Brief, a framework for an online (real-time) 6 degrees-of-freedom evaluation platform is detailed. The platform allows psychoacoustic research and subjective testing of binaural audio renderers for virtual reality applications and finds application in the development of the MPEG-I Audio Standard.
