Designing sound-based computer games

Designing sound-based interactive entertainment for visually impaired users poses several challenges. This article points out some central issues faced when developing sound-based computer games. The three games described here were developed for the Swedish Library of Talking Books and Braille (TPB), to be published on the TPB Internet site [1]. These games, Towers of Hanoi, Memory and Tag, can...

Computer-based sound spectrograph system.

Sound spectrographs based on digital computers are of interest because of the versatility they offer in generating and displaying sound spectrograms. A particular computer-based sound spectrograph is described in which digitized time waveforms stored on disk memory are spectrally analyzed and the resulting data stored back on disk for later display. Analyses are also performed to obtain the voi...

Interactive Physically-based Sound Simulation

Nikunj Raghuvanshi: Interactive Physically-based Sound Simulation. (Under the direction of Ming C. Lin.) The realization of interactive, immersive virtual worlds requires the ability to present a realistic audio experience that convincingly compliments their visual rendering. Physical simulation is a natural way to achieve such realism, enabling deeply immersive virtual worlds. However, physica...

Computer Simulation Techniques for Acoustical Design of Rooms - How to Treat Reflections in Sound Field Simulation

The paper presents a number of problems related to sound reflections, and possible solutions or approximations that can be used in computer models. The problems include: specular and diffuse reflections, early and late reflections, scattering due to rough structure of surfaces, diffraction due to finite size of surfaces, curved surfaces, convex and concave surfaces, angle dependent absorption. ...
