THREE-DIMENSIONAL SOUND REPRODUCTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional sound reproduction system that can realize high quality three-dimensional graphics and a three-dimensional sound. SOLUTION: A host processor section 101 transfers scene data, a drawing command and a sound command to a geometric arithmetic unit 102. The geometric arithmetic unit 102 generates two-dimensional object data for graphic and calculates a geometrical relation between a sound source and a listening point. A sound generator 105 reads sound data of a sound source designated by the sound command from a sound memory 105 and processes the sound data on the basis of the geometrical information between the sound source and the listening point from the geometric arithmetic unit 102 to reproduce a sound in a three-dimensional space.
