Abstract: 3D audio technology is well known from cinema, computer games, and virtual reality and it is gaining more and more importance. Usually, consumers do not have a suitable multichannel loudspeaker system at home, whether for scene-based, channel-based, or object-based productions. Thus, a viable solution for the living room is to decode the 3D audio material for binaural playback via headphones. However, the 3D audio scene can only be fully experienced if head movements are also taken into account which requires a tracking sensor to modify the sound field accordingly. Although there are technically simple and inexpensive hardware solutions available, they are not part of the standard home equipment. An alternative for head tracking is to use the webcam of the user's device. The Cat3DA (camera-tracked 3D audio) player relies on conventional equipment that most users already have at home: pc or laptop equipped with a webcam and a pair of standard headphones for binaural playback of a virtual loudspeaker setup. The player also incorporates binaural impulse responses of different listening rooms to support externalization of the sound scene.
