This talk is in two parts. The first part considers the traditional science of 3D hearing, with a contrast made with the visual system. The second part explores the
inherent limitations of a physics/DSP approach, and some of the other elements that are hard (impossible) to solve by 'just throwing a bunch of DSP at it.'
Audio is a sometimes overlooked and often misunderstood element of the
VR/AR/XR experience. This session will cover the theory, practice and
limitations of 3D hearing for augmented and virtual reality systems as
well as some brief history of commercially deployed 3D audio systems.
Better understanding the limits not only of current 3D audio
technologies but also human hearing perception itself can lead to
greatly improved VR/AR/XR experiences, and reduce frustrations all
About our Presenter
Brian Schmidt is a consultant and 32 year veteran of the game and interactive audio industry. The recipient of the 2008 Game Audio Network Guild Lifetime Achievement
Award, he has worked as both a composer/sound designer and audio technologist, working with clients worldwide including Microsoft, Sony, Sega, Electronic Arts,
Magic Leap and more. He has been working with 3D audio in particular for three decades beginning as a student at Northwestern University where he received bachelors
degrees in both Music and Computer Science and a Masters in Computer Music. In the 90's he designed the QSound "Q1"chip, the first real-time 3D audio arcade chip used by
Capcom of Japan; as the program manager for the Xbox audio team at Microsoft, he helped design 3D audio technology into the original Xbox game console. In 2012, he developed a mobile
3D audio-based game, Ear Monsters, using spatial sound as the primary gameplay mechanic. Today he continues to consult for companies such as Magic Leap on 3D audio technology as well
as actively compose for games such as Game of Thrones Pinball and Mutant Football League. Brian is also a speaker and educator and is and the Founder and Executive Director of GameSoundCon,
the largest professional conference on audio for Games and Virtual Reality. Brian currently sits on the Game Developers Conference Advisory Board and has served as President of the Game Audio
Network Guild since 2012. An avid pinball fan, he was inducted into the Pinball Expo Hall of Fame in 2017 for his work in music and sound design.
Brian received undergraduate degrees in music and computer science from Northwestern University, where he
created the dual degree program between the School of Music and the Technological Institute. He went on to complete his master's degree in computer applications in music in 1987,
and portions of his thesis work appeared in Computer Music Journal. Brian also presented his thesis work, by invitation, to the Audio Engineering Society (AES) special conference
on audio technology. Brian is a frequent and in-demand speaker, as well as the founder and executive director of GameSoundCon, the largest professional conference on game music and
sound design. Currently, he is a Senior Lecturer at DigiPen Institute in Redmond.
Zoom accounts have finite attendee counts, so we are using Eventbrite to manage reservations.
You do not need to create an Eventbrite account to reserve a ticket.

Please give your full name, email address, location, and AES member status.
Get this part right, your ability to join the meeting depends on it. We ask for your location because we're curious and your AES member status because we need to report
member count at our meetings to HQ.
Approximately a week before the event, we will send email to everyone who has responded giving the Zoom meeting link. There will be a reminder email on the day of the event.
If you don't get the notice, do let us know at
When you're live on Zoom, please set your screen name to be your real name in whatever form you wish (John Smith, johnsmith), as long as it includes your first
and last real names. If you don't follow this convention, we will not let you join the meeting.
One of the best features of all our meetings is self-introductions from the participants, because it is always fascinating to hear who you are and what you do. We will do
our best to have this after the Intermission. On your end, a camera-equipped computer (or tablet) would be nice, as well as a microphone. We don't think that a smartphone
will be a very satisfactory platform to view this meeting, nor will a landline telephone.
It could be that you'll need to send your comments/questions via zoom-chat or perhaps by email. We're still working those details through.
We will hold our annual officer and committee member election at our June meeting. Officers (Chair, Vice Chair, Secretary, and Treasurer)
are typically nominated from the existing Committee. Committee members can be anyone interested and willing to help your section produce
meetings. Officers serve for one year. Committee members serve for two years, with half electing on odd numbered years, and the other half electing on even numbered years.
The current list of officers and committee members can be found
If you are interested in participating, please contact anyone on the list. You must be a member or associate member at the time you assume the position. More information
about Officer or Committee duties can be found
at this link.
