In this paper, we introduce a new object-based 3D audio scene representation scheme. Typically, four kinds of 3D sound source objects are defined. Point sound source, line sound source, plane sound source and volume sound source are defined 3D sound source objects that are used for representation of object-based 3D audio scene. Each 3D sound source object includes sound source samples and related 3D audio scene information. User can interact with 3D sound source object and control the object by modifying the 3D audio scene information. We implement a prototype of object-based 3D audio player and several contents for demonstration of object-based 3D audio features. This object-based 3D audio representation scheme can be used very wide range of applications, like interactive game, home shopping and broadcasting realistic ambient sounds.
