Method for generating and consuming 3-d audio scene with extended spatiality of sound source

Abstract

A method of generating and consuming 3D audio scene with extended spatiality of sound source describes the shape and size attributes of the sound source. The method includes the steps of: generating audio object; and generating 3D audio scene description information including attributes of the sound source of the audio object.

What is claimed is: 
     
         1 . A method for processing a three-dimensional audio scene, comprising:
 generating, by a computer, a sound object related to at least one of sound source;   generating, audio scene information including sound source characteristics information for the sound object;   transmitting the sound object and the audio scene information,   wherein the sound source characteristics information is related to extension pattern of sound source in the three-dimensional space.   
     
     
         2 . The method as recited in  claim 1 , wherein the sound source characteristics information comprise at least one of a shape, a size or a dimension of the sound source expressed in a three-dimensional space. 
     
     
         3 . The method as recited in  claim 2 , wherein the size is expressed as x 0 −Δx, y 0 −Δy, z 0 −Δz; x 0 , y 0 , z 0 ; and x 0 +Δx, y 0 +Δy, z 0 +Δz. 
     
     
         4 . The method as recited in  claim 3 , wherein Δx, Δy, and Δz are calculated based on a vector between a listener and the location of the sound source, or angle between a direction vector of the sound source. 
     
     
         5 . The method as recited in  claim 1 , wherein the three-dimensional space is related to output space of the sound source. 
     
     
         6 . A apparatus for processing a three-dimensional audio scene, comprising:
 generating unit generates a sound object related to at least one of sound source, and audio scene information including sound source characteristics information for the sound object; and   transmitting unit transmits the sound object and the audio scene information,   wherein the sound source characteristics information is related to extension pattern of sound source in the three-dimensional space.   
     
     
         7 . The apparatus as recited in  claim 6 , wherein the sound source characteristics information comprise at least one of a shape, a size or a dimension of the sound source expressed in a three-dimensional space. 
     
     
         8 . The apparatus as recited in  claim 7 , wherein the size is expressed as x 0 −Δx, y 0 −Δy, z 0 −Δz; x 0 , y 0 , z 0 ; and x 0 +Δx, y 0 +Δy, z 0 +Δz. 
     
     
         9 . The apparatus as recited in  claim 8 , wherein Δx, Δy, and Δz are calculated based on a vector between a listener and the location of the sound source, or angle between a direction vector of the sound source. 
     
     
         10 . The apparatus as recited in  claim 6 , wherein the three-dimensional space is related to output space of the sound source. 
     
     
         11 . A computer program embodied on a non-transitory computer readable medium, the computer program being configured to control a processor, wherein the computer program comprising:
 a sound object related to at least one of sound source; and   audio scene information including sound source characteristics information for the sound object   wherein the sound source characteristics information is related to extension pattern of sound source in the three-dimensional space.   
     
     
         12 . The computer program as recited in  claim 11 , wherein the sound source characteristics information comprise at least one of a shape, a size or a dimension of the sound source expressed in a three-dimensional space. 
     
     
         13 . The computer program as recited in  claim 12 , wherein the size is expressed as x 0 −Δx, y 0 −Δy, z 0 −Δz; x 0 , y 0 , z 0 ; and x 0 +Δx, y 0 +Δy, z 0 +Δz. 
     
     
         14 . The computer program as recited in  claim 13 , wherein Δx, Δy, and Δz are calculated based on a vector between a listener and the location of the sound source, or angle between a direction vector of the sound source. 
     
     
         15 . The computer program as recited in  claim 11 , wherein the three-dimensional space is related to output space of the sound source.
