AB  - We present implementation procedure of the interactive 3D audio player using MPEG-4 standards. MPEG-4 standards allow to interact with important objects in a scene as well as to provide the high efficiency coding tools for audiovisual objects. We apply the AudioBIFS system (version 1), parts of the BIFS in the MPEG-4 Systems standards, to provide an object-based interactivity for audio objects. It also provides geometric information for spatializing an audio object into the 3D audio scene. Because the method of 3D spatialization is not normative in the MPEG-4 AudioBIFS, we adopt a novel 3D spatialization method based on HRTF processing. To prohibit excessive increase of the number of audio objects, we defined the background audio object to present the atmosphere of 3D audio scene. While the important audio objects are separated as audio objects individually, the other audio objects are merged into the background audio object. Though our interactive 3D audio player is developed for a terminal player in Digital Multimedia Broadcasting (DMB) system, it can be also applied to 3DTV, virtual reality games, interactive home shopping applications, etc.
