Abstract:
1. A method for processing a three-dimensional audio scene with a sound source whose spatiality is extended, comprising: generating, by a computer, a sound object composing the audio scene; and generating, by the computer, three-dimensional audio scene description information including sound source characteristics information for the sound object, the three-dimensional audio scene description information including a plurality of point sound sources that model the sound object, wherein the sound object includes the plurality of point sound sources, wherein the sound source characteristics information includes spatiality extension information of the sound source, which is information on a size and shape of the sound source expressed in a three-dimensional space, and the plurality of point sound sources are distributed uniformly over a surface defined by the three-dimensional space, and wherein the spatiality extension information of the sound source includes sound source dimension information that is expressed as x
