The CCRMA Hearing Seminar finishes off the year with Steve Shepard
describing and demonstrating the state of the art in 3D sound production.
How is it that we can use two speakers or headphones to create a 3D virtual
acoustic environment. Can we do better than what we are used to with a
pair of stereo speakers? What techniques work? Which ones are smoke and
mirrors? What should you listen for if somebody tells you they have solved
the problem?
Come to CCRMA next Thursday to find out more. Steve Shepard has been
studying this problem at CCRMA and SGI.
Who: Steve Shepard
What: Spatial Audio Synthesis and Reproduction
When: Thursday December 8 at 11AM
Where: CCRMA Library ( Top Floor of the Knoll)
I'm just back from the NIPS conference. There were a bunch of interesting
audio perception talks. I'll send a summary and pointers later. I've got a
couple of ideas for talks too.
See you at CCRMA.

Spatial Audio Synthesis and Reproduction
Steve Shepard
Silicon Graphics
With advances in the signal processing power of consumer electronics
devices and increasing interest in technologies relating to "the M
word", spatial audio synthesis (the process of creating audio cues
that are perceived to come from sources located at arbitrary positions
in the 3D space around the listener) has begun to move out of the
research labs and into commercial applications. However, there are
still many open questions and challenges to successful implementation
of this technology.
In this talk, I will review current literature on sound localization,
discuss the issues involved in synthesizing spatial or "3-D" audio
cues, and present techniques for reproducing these cues over both
headphones and speakers.
Audio examples will be served.
