Abstract

PARA TRANSMITIR O ALMACENAR SEÑALES DE AUDIO MULTICANAL, DIGITALIZADAS QUE SON REPRESENTADAS DE FORMA DIGITAL MEDIANTE UNA PLURALIDAD DE SEÑALES DE BANDA DE ESPECTRO PARCIAL, EN EL CODIFICADOR, LOS SEÑALES DE BANDA PARCIAL DE DIFERENTES CANALES DE AUDIO, PERO DISPONIENDO DE LA MISMA FRECUENCIA EN POSICION, SON COMBINADAS A TRAVES DE CANALES DE ACUERDO CON UNA SEÑAL DE CONTROL DINAMICA. ESTA SEÑAL DE CONTROL SE DERIVA A PARTIR DE VARIOS CANALES DE AUDIO MEDIANTE UN ANALISIS DE SEÑAL DE AUDIO BASADO EN UN MODELO PSICOACUSTICO EN EL LADO DEL DECODIFICADOR. LAS SEÑALES DE BANDA PARCIAL DE VARIOS CANALES DE AUDIO DISPONIENDO DE LA MISMA POSICION DE FRECUENCIA SON DISASOCIADAS A LO LARGO DE CANALES DE ACUERDO CON UN VALOR DE CONTROL DERIVADO A PARTIR DE LA SEÑAL DE CONTROL DINAMICA, TRANSMITIDA O ALMACENADA.
