This paper details an effort towards incorporating audio source localization as an input to virtual reality systems, focusing primarily on games. The goal of this research is to find a novel method to use localized live audio as an input for level generation or creation of elements and objects in a virtual reality environment. The paper discusses the current state of audio-based games and virtual reality, and details the design requirements of a system consisting of a circular microphone array that can be used to localize the input audio. The paper also briefly discusses signal processing techniques used for audio information retrieval and introduces a prototype of an asymmetric virtual reality first-person shooter game as a proof-of-concept of the potential of audio source localization for augmenting the immersive nature of virtual reality.
