Abstract:
1. An audio system comprising: an audio source; a playing terminal adapted to be coupled to the audio source by a data link; and an audio transducer arrangement adapted to be coupled to the playing terminal, the audio source being arranged to derive an audio component comprising (a) audio data corresponding to aural content of an audible sound or track, and (b) positional data corresponding to the position in space relative to transducers of the audio transducer arrangement, at which the audible sound or track is to be perceived by a user, the audio source being arranged to be coupled with the playing terminal so the positional data (b) and the audio data (a) are coupled from the audio source to the playing terminal at first and second bit rates, respectively, where the second bit rate is lower than that of the first bit rate, the playing terminal being arranged to cause the transducers of the audio transducer arrangement to derive aural outputs in accordance with the audio data (a) and the positional data (b).
