METHOD FOR GENERATING AND CONSUMING THREE-DIMENSIONAL AUDIO SCENE HAVING SOUND SOURCE OF EXTENDED SPATIAL CHARACTERISTIC

摘要

PURPOSE: A method for generating and consuming a three-dimensional audio scene having a sound source of an extended spatial characteristic is provided to form effectively the three-dimensional sound by extending the spatial characteristic of a content sound source. CONSTITUTION: A generation process for generating a sound object is performed. The three-dimensional audio scene technique information including the sound source characteristic information for the sound object is generated. The sound source characteristic information includes the spatial extension information of the sound source as the intensity information and the shape information of the sound source expressed in the three-dimensional space. The spatial extension information of the sound source is expressed by an x-element, a y-element, and a z-element of three-dimensional coordinates.
