With the rise of consumer-level virtual and augmented reality, there has been renewed interest in spatial sound. While this interest has been exciting for sound researchers, for newcomers to spatial sound the field can be fraught with technical terminology and a wide range of tools. This paper presents an introduction to spatial sound rendering in virtual environments (VEs: including games, augmented and virtual reality). We introduce a short overview of spatial sound, explore the aspects necessary to recreate spatial (virtual or 3D) sound, and present an overview of the common tools used in today’s major game development engines to create spatial sound in VEs.
