[Visinfo] Week 4 IGERT seminar

[Corina S. Schweller]

The seminar this week was about 'Capturing and Rendering Spatial Audio' 
by Ramani Duraiswami. The goal was to create a virtual environment that 
has the sound placed in proper spatial locations. By measuring the 
intensity and velocity of sound on a two ear model a formula can be 
derived that would allow for spatial placement of the sound. You can 
compute the response to a general source by convolution, knowing the 
Impulse Response. The Head Related Transfer Function takes into account 
the scattered sound off of the human form. The Room Model explores the 
scattering of sound in an environment. The problem faced with these 
sound placement functions is the differences in human bodies. There are 
differences in the shapes of our ears and bodies that cause the sound 
scattering to vary and would affect our perception of sound in virtual 
environments.
