Hey everybody! I’m video game composer Winifred Phillips. At this year’s Game Developers Conference in San Francisco, I was pleased to give a presentation entitled Music in Virtual Reality (I’ve included the official description of my talk at the end of this article). While I’ve enjoyed discussing the role of music in virtual reality in previous articles that I’ve posted here, the talk I gave at GDC gave me the opportunity to pull a lot of those ideas together and present a more concentrated exploration of the practice of music composition for VR games. It occurred to me that such a focused discussion might be interesting to share in this forum as well. So, with that in mind, I’m excited to begin a four-part article series based on my GDC 2018 presentation!
In this blog, I thought we might take a quick look at the development of the three dimensional audio technologies that promise to be a vital part of music and sound for a virtual reality video game experience. Starting from its earliest incarnations, we’ll follow 3D audio through the fits and starts that it endured through its tumultuous history. We’ll trace its development to the current state of affairs, and we’ll even try to imagine what may be coming in the future! But first, let’s start at the beginning:
In the 1930s, English engineer and inventor Alan Blumlein invented a process of audio recording that involved a pair of microphones that were coincident (i.e. placed closely together to capture a sound source). Blumlein’s intent was to accurately reflect the directional position of the sounds being recorded, thus attaining a result that conveyed spatial relationships in a more faithful way. In reality, Blumlein had invented what we now call stereo, but the inventor himself referred to his technique as “binaural sound.” As we know, stereo has been an extremely successful format, but the fully realized concept of “binaural sound” would not come to fruition until much later.
