Abstract

PARA REDUCIR LOS EFECTOS DE INTERFERENCIA DURANTE LA REDUCCION DE DATOS DE UNA SEÑAL DE AUDIO YA REDUCIDA, O DURANTE LA PRIMERA REDUCCION DE DATOS DE UNA SEÑAL DE AUDIO, PERMITIENDO LAS VIOLACIONES DE CODIGO, LA INVENCION PROPONE QUE EN EL CASO DE QUE UN CODIGO HAYA SIDO SOBREPASADO, SE SELECCIONA UN CODIGO QUE SUMINISTRA LA INTERFERENCIA OPTIMA DE DISTRIBUCION CON REFERENCIA A LA CALIDAD DE REPRODUCCION. EL COMPORTAMIENTO DE TIEMPO Y/O LA DISTRIBUCION ESPECTRAL DE LA SEÑAL DE AUDIO PUEDE SER MODIFICADA, EN PARTICULAR ANTES DE LA CODIFICACION, DE ACUERDO CON UN MODELO DE AJUSTE SELECCIONADO, SIN QUE SE PRODUZCA NINGUNA DETERIORACION SIGNIFICANTE DE LA SEÑAL, SIENDO PERCEPTIBLE DE FORMA SUBJETIVA POR LA PERSONA QUE ESCUCHA DESPUES DE LA DECODIFICACION.
