METHOD FOR THE SOUND PROCESSING OF A STEREOPHONIC SIGNAL INSIDE A MOTOR VEHICLE AND MOTOR VEHICLE IMPLEMENTING SAID METHOD

摘要

THE INVENTION RELATES TO A METHOD FOR THE SOUND PROCESSING OF A STEREOPHONIC SIGNAL INSIDE A MOTOR VEHICLE. IN A FIRST EMBODIMENT (“DRIVER” MODE), THE STEREOPHONIC SOUND SOURCE IS CENTERED IN THE MIDDLE OF THE DASHBOARD FOR THE “DRIVER” LISTENING POSITION. FOR THIS REASON, DELAYS (t1-t4) ARE INTRODUCED IN FREQUENCY BANDS OF THE CHANNELS DELIVERED BY THE SPEAKERS SO THAT THE DRIVER (62) SEEMS TO BE IN THE CENTER OF A CIRCLE (C) AT WHICH THE LISTENING POSITION OF THE CAR IS SET. IN A SECOND EMBODIMENT (“ALL PASSENGERS” MODE), THE PHASES OF THE TWO FRONT CHANNEL SIGNALS ARE EQUALIZED SO THAT THE SOUND SOURCE (67, 68) SEEMS TO BE CENTERED ON THE DRIVER (62) AND THE FRONT PASSENGER (70) OF THE VEHICLE.
