Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO (10) DE UN SISTEMA DE PUESTA EN PRACTICA DE AMPLIFICACION ACUSTICA, RECIBIENDO DICHO SISTEMA UN GRUPO DE SEÑALES DE AUDIO MULTICANAL (18) Y CREA UN ENTORNO SIMULADO DE AMBIOFONIA POR LECTURA DE DOS SEÑALES DE SALIDA (26, 28) UNICAMENTE. LAS SEÑALES DE AUDIO MULTICANAL (18) INCLUYEN UN PAR DE SEÑALES FRONTALES DESTINADAS A LEERSE A PARTIR DE UNA ETAPA DE AUDIO FRONTAL Y UN PAR DE SEÑALES POSTERIORES DESTINADAS A LEERSE A PARTIR DE UNA ETAPA DE AUDIO POSTERIOR. LAS SEÑALES FRONTALES Y POSTERIORES SON MODIFICADAS POR PARES MEDIANTE UN PROCESADOR (24) DE INMERSION SONORA MULTICANAL. EL PROCESADOR DE INMERSION DE AUDIO MULTICANAL (24) SEPARA UNA COMPONENTE AMBIENTE DE CADA PAR DE SEÑALES CON RESPECTO A UNA COMPONENTE DIRECTA Y PROCESANDO AL MENOS ALGUNOS DE LOS COMPONENTES CON UNA FUNCION DE TRANSFERENCIA RELACIONADA CON LOS MOVIMIENTOS DE LA CABEZA. EL TRATAMIENTO DE LAS COMPONENTES INDIVIDUALES DE SEÑAL DE AUDIO VIENE DETERMINADO POR UNA POSICION DE LECTURA ELEGIDA DE LAS SEÑALES DE AUDIO ORIGINALES CORRESPONDIENTES. LAS COMPONENTES INDIVIDUALES DE SEÑAL DE AUDIO SON LUEGO SELECTIVAMENTE COMBINADAS CON LAS SEÑALES DE AUDIO ORIGINALES PARA FORMAR DOS SEÑALES DE SALIDA AMPLIFICADAS (L OUT Y R OUT ), LO QUE PERMITE GENERAR, EN LECTURA, UN SONIDO AMBIOFONICO.
