3D Audio

Part number: 
Activity status: 

3D Audio is a standard for
1. "3-D Audio" in which there may be many loudspeakers used in the audio presentation. Issues are how to automatically adapt audio program material to the target number of loudspeakers in a given consumer's listening venue.
2. "Audio for new video presentation" in which the video will very high resolution (as in HEVC) that permits a closer viewing distance such that the user is within the audio near field. Issues are how the audio presentation (i.e. number and position of loudspeakers) can enhance sound source localization and the sense of immersiveness. Both large "home theatre" and smaller portable audio-visual presenations are being considered.
