ABSTRACT:
A four-dimensional acoustical audio system utilizes both spatial and temporal signal processing to maximize the depth, width, and perceived directionality of the acoustic field with respect to the binaural auditory system. Transducers are critically placed within the confines of a reverberant enclosure, and each transducer is assigned a specific bandwidth of sound either in mono or stereo, depending upon the spatial location of the transducer to take advantage of the binaural auditory system of the intended listener. The system minimizes the number of transducers and electronics required to achieve the effect of a live performance, regardless of the dynamics of the enclosure in which it is placed. The loudspeaker system can be used in small enclosed volumes such as an automobile or extended to volumes the size of a motion picture theater or concert hall and even outdoors.
