| titleOfInvention | Six-axis surround sound processor with improved matrix and cancellation control |
| abstract | A surround sound processor (1) for redistribution of stereophonic audio signals (2, 4) into multiple channels for presentation on a plurality of loudspeakers surrounding a listener has an improved direction detector filter circuit (8), a peak hold circuit in the direction detector for better dynamic separation, improved time constants in the servologic circuit (16), improved linearity correction in the control voltage generator (18-28) to match the characteristics of the new voltage controlled amplifiers (32-40) which are applied to the separation matrix (30), a separation matrix (30) having cancellation of unwanted signals without gain modification for desired signal components, and improved shelf filters in the rear channel outputs. |
