METHOD FOR GENERATING AND CONSUMING 3D AUDIO SCENE WITH EXTENDED SPATIALITY OF SOUND SOURCE

摘要

PROBLEM TO BE SOLVED: To produce more effective 3D sounds by extending spatiality of sound sources of contents.

SOLUTION: An illustrated sound source forms a plane sound source including an area of Δy×Δz by being extended vertically to a vector defined in a "direction" field based on "source Dimension" field values (0, Δy, Δz). Thus, when the dimension and location of the sound source are defined, a point sound source is located on a surface of the extended sound source. In the present invention, the locations of the point sound sources are calculated so as to be distributed uniformly on the surfaces of the extended sound source.
