The Game Developers Conference is almost here! I’m looking forward to giving my presentation soon on “Music in Virtual Reality” (Thursday, March 22nd at 3pm in room 3002 West Hall, Moscone Center, San Francisco).  Over the course of the last two years, I’ve composed a lot of music for virtual reality projects, some of which have already hit retail, and some of which will be getting released very soon!  As a result, I’ve spent a lot of time thinking about what role music should play in a virtual reality game. During my GDC talk in March, I’ll be taking my audience through my experiences composing music for four very different VR games –the Bebylon: Battle Royale game from Kite & Lightning, the Dragon Front strategy game from High Voltage Software, the Fail Factory comedy game from Armature Studio, and the Scraper: First Strike RPG-Shooter hybrid from Labrodex Inc.  In preparing my GDC presentation, I made sure my talk addressed some of the most important creative and technical hurdles facing video game composers working in VR.  However, time constraints ensured that some interesting info ended up ‘on the cutting room floor,’ so to speak.  So, I’ve written two articles that explore some of the best topics that didn’t make it into my GDC presentation.

My previous article focused on some abstract, creative concerns facing video game music composers and audio folks working in VR.  In this article, we’ll be turning our attention to more concrete technical issues.  Ready?  Let’s go.

New Binaural Developments

Understanding Audio in VR – A Game Music Composer’s Resource Guide

When I’m not at work in my studio making music for games, I like to keep up with new developments in the field of interactive entertainment, and I’ll often share what I learn here in these articles.  Virtual reality is an awesome subject for study for a video game composer, and several of my recent projects have been in the world of VR.  Since I’m sure that most of us are curious about what’s coming next in virtual reality, I’ve decided to devote this article to a collection of educational resources.  I’ve made a point of keeping our focus general here, with the intent of understanding the role of audio in VR and the best resources available to audio folks.  As a component of the VR soundscape, our music must fit into the entire matrix of aural elements, so we’ll spend this article learning about what goes into making expert sound for a virtual reality experience. Let’s start with a few articles that discuss methods and techniques for VR audio practitioners.

VR Audio: Past, Present & Future

VR Audio (article by award winning video game music composer Winifred Phillips)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:

3D Audio of the Past

Alan Blumlein (article by award winning video game music composer Winifred Phillips)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.
