Abstract

LA ILUSION PROPORCIONADA AL OYENTE DE FUENTES DISTINTAS DE SONIDO DISTRIBUIDAS EN UN ESPACIO TRIDIMENSIONAL SE OBTIENE UTILIZANDO UN EQUIPO DE REPRODUCCION ESTEREOFONICO CONVENCIONAL, PROCESANDO SEÑALES SONICAS MONOAURALES ANTES DE LA REPRODUCCION EN DOS TRANSDUCTORES SEPARADOS. UNA PLURALIDAD DE DICHS SEÑALES PROCESADAS CORRESPONDIENTES A DIFERENTES POSICIONES DE FUENTE SONICA SE MEZCLAN UTILIZANDO TECNICAS CONVENCIONALES SIN PERTURBAR LAS POSICIONES DE LA SIMAGENES INDIVIDUALES. AUNQUE SE PRECISAN DOS ALTAVOCES, EL SONIDO PRODUCIDO NO ES UN SONIDO ESTEREOFONICO CONVENCIONAL, SIN EMBARGO, CADA CANAL DE UNA SEÑAL ESTEREOFONICA IZQUIERDA/DERECHA PUEDE SER PROCESADA SEPARADAMENTE DE ACUERDO CON EL INVENTO Y COMBINADAS PARA SU REPRODUCCION. EL PROCESAMIENTO DEL SONIDO INCLUYE LA DIVISION DE CADA SEÑAL DE CANAL MONAURAL O UNITARIO EN DOS SEÑALES Y ENTONCES SE AJUSTA LA FASE Y LA AMPLITUD DIFERENCIALES DE LAS DOS SEÑALES DE CANAL EN BASE A LA FRECUENCIA DE ACUERDO CON UNA FUNCION DE TRANSFERENCIA DERIVADA EMPIRICAMENTE QUE TIENE UNA FASE ESPECIFICA Y UN AJUSTE DE AMPLITUD PARA CADA INTERVALO DE FRECUENCIA PREDETERMINADA SOBRE EL ESPECTRO AUDIO. CADA FUNCION DE TRANSFERENCIA SE DERIVA EMPIRICAMENTE PARA RELACIONARSE CON UN PUNTO DE ALIMENTACION DE SONIDO DIFERENTE Y PROPORCIONANDO UN NUMERO DE FUNCIONES DE TRANSFERENCIA DIFERENTES Y SELECCIONANDOLAS DE FORMA ADECUADA DE MODO QUE PAREZCA QUE LA FUENTE SONICA SE MUEVE.
