Claim 5:
6. The virtual surround sound process for loudspeaker systems according to claim 1, wherein:
said extracting information to produce plural spatial representation outputs comprises producing a “Left (L)”, a “Right (R)”, “Center (C)”, a “Left Surround Rear (LSR)”, a “Right Surround Rear (RSR)”, a “Left Side Surround (LSS)”, a “Right Side Surround (RSS)”, a “Low Frequency Effects (LFE)”, a “Top Surround L (TSL)”, and a “Top Surround R (TSR)”, output path;
connecting the (L) output to a “Processing Bus A”;
connecting the (R) output path to a “Processing Bus B”;
connecting the (C) output path is connected to “Processing Bus A” and “Processing Bus B”;
connecting the (LFE) output path to “Processing Bus A” and “Processing Bus B”;
connecting the (LSR) output path to a convolution engine, processed by an HRTF filter with an externally controllable azimuth and elevation (impulse response), connected to a crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus A”;
connecting the (RSR) output to a convolution engine, processed by an HRTF filter with an externally controllable azimuth and elevation (impulse response), connected to crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus B”;
connecting the (LSS) output to a convolution engine, processed by an HRTF filter with an externally controllable azimuth and elevation (impulse response), connected to crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus A”;
connecting the (RSS) output to a convolution engine, processed by an HRTF filter with an externally controllable azimuth and elevation (impulse response), connected to crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus B”;
connecting the (TSL) output to a convolution engine, processed by an HRTF filter with a controllable azimuth and elevation (impulse response), connected to a crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus A”;
connecting the (TSR) output path to a convolution engine, processed by an HRTF filter with a controllable azimuth and elevation (impulse response), connected to crosstalk cancelation processing block with a controllable loudspeaker width, and then connecting the output thereof to “Processing Bus B”;
connecting the Processing Bus A to an equalization and dynamic control processing block, and then connecting the output thereof to a Left Loudspeaker;
connecting the Processing Bus B to an equalization and dynamic control processing block, and then connecting the output thereof to a Right Loudspeaker.
