ABSTRACT:
System and method for enhancing the spatial effect of sound produced by a sound system. In an exemplary embodiment, the system includes a reverberator and a sound spatialization unit, which are a combination of filter(s), attenuator(s), differentiator(s), adder(s) and phase shifter(s). The present invention creates sound images at different spatial locations for different frequencies by employing a phase shifted high frequency reverberated signal. As a result, the loud speakers produce sound images located at several spatial positions, producing a perception that there is an array of loudspeakers surrounding a listener.
