Paper Abstract

Virtual audio environment is an essential part in making virtual environments more real. To solve the problems in the traditional methods of contributing virtual audio environment, for an instant, the heavy cost of time and the monotony in presenting audio sources, a fast audio ray tracing method is put forward in this thesis. Then research work is done in the three stages of the whole process, which are modeling and presentation of audio signals, imitation of audio transportation and feeling of sound. That will function as a basal theory in contributing audio environment. The major point of this part is about three courses below. They are band-pass arrangement of audio signals, different processes of sound in different bands, combination of sound serials and the synchronization of sounds as walking in 3D environment.
