I made a demo with some audio technique, 3D holophonic sound. I note you that this only works with headphones or at least earphones.
Using the experimental data which maps the transfer functions of human auditory system, I show you real-time 3D holophonic sound effect in game is possible. Though the sound quality is quite bad since I used very rough numerical integration method, I want to emphasize that the 'feeling of existence' can be further increased not only by the visual, but also the sound.
This is the very 'prototype' and proof-of-principle demo, so the experince may not be perfect. In especially, the feeling of localized sound may be different from person to person, because the transfer functions related to the individual heads are all different. Also I only mapped the horizontal plane. This means you can only distinguish the direction of sound in the horizontal plane (Update soon..)
There are three audio samples in the demo : footstep, crunching and something shaking sound.
I don't have my dev kit yet, so I need your feed back. Thanks!
