Abstract
PARA QUE SE REQUIERA SOLAMENTE UN INCREMENTO RELATIVAMENTE PEQUEÑO EN LA CUOTA DE DATOS ENTRE EL NUMERO DE CANALES DE UN SISTEMA DIGITALIZADO DE CANALES MULTIPLES Y CON UNA SEÑAL AUDIO REDUCIDA DE CUOTA DE BIT, SE APROVECHA EL ENCUBRIMIENTO PSICOAUSTICO MEDIANTE AL MENOS PARTE DE LOS CANALES AUDIO QUE PERMANECEN O MEDIANTE LA REDUNDANCIA DE CANALES AUDIO INDIVIDUALES DE CADA CANAL AUDIO INDIVIDUAL CUANDO SE REDUCE LA CUOTA DE BIT DE LAS SEÑALES DE AUDIO DISPONIENDO DE MAS DE DOS CANALES DE AUDIO. SOLAMENTE AQUELLAS PARTES QUE CONCIERNEN AL CANAL AUDIO SON TRANSMITIDAS O ACUMULADAS PERO NO ESTAN OCULTAS POR MEDIO DE LAS SEÑALES DE AUDIO O DE OTROS CANALES AUDIO QUE SON CONTENIDAS EN LOS CANALES AUDIO PARA REPRODUCCION ESTEREOFONICA CON TODOS LOS TIPOS DE REPRODUCCION DISPONIBLE POR SELECCION. ADICIONALMENTE, LAS PARTES UTILIZADAS SON TRANSMITIDAS O ACUMULADAS CON UNA RESOLUCION SOLAMENTE GRANDE DE FORMA SUFICIENTE PARA LA TOTALIDAD DE LOS CANALES DE AUDIO QUE PERMANECEN OCULTOS EN LA CUANTIZACION DEL SONIDO GENERADO DURANTE LA CUANTIZACION EN TODOS LOS TIPOS DE REPRODUCCION DISPONIBLES POR SELECCION.
