GENERATION APPARATUS, GENERATION METHOD, AND GENERATION PROGRAM

WIPO Patent Application WO/2023/119451

A1

This generation apparatus (100) comprises: a coefficient acquisition unit (120) that acquires, upon detection of an interaction of an object mapped onto a cyberspace, coefficient information of the object on the basis of raw material information of the object; a sound source selection unit (130) that inputs position information, shape information, and coefficient information of the object into a machine learning model, to thereby calculate statistical information in which the type of a sound source corresponding to the interaction of the object is associated with an intensity of the sound source, and selects sound source information corresponding to the statistical information; and a sound synthesizing unit (140) that generates synthesized sound source information by synthesizing sound source information on the basis of the statistical information and the sound source information, and executes a three-dimensional sound rendering based on the position information with respect to the synthesized sound source information, to thereby generate three-dimensional sound source information in which the synthesized sound source information is three-dimensionally represented.
