3D Localisation of Sound Sources in Virtual Reality

Abstract

This paper presents a comparison of 3D localisation of sound sources using various 3D audio engines for Virtual Reality (VR) environments. An experiment was created with the Oculus Spatializer, Unity Default engine, Unity Reverb engine and the AM3D Spatializer. These four engines were tested against each other in a Virtual Reality setting, where the tester was tasked with the localisation of invisible audio sources present in the virtual room. The evaluation of the experiment showed that there were statistically significant differences between the four engines under specific circumstances.
