Abstract

Se proporciona un método y un aparato para mezclar porciones análogas y digitales de una señal de difusión de radio digital compuesta al procesar paquetes de audio comprimido para calcular los valores de indicador de calidad de audio digitales correspondientes, almacenar los paquetes de audio comprimidos en una memoria intermedia de mezcla de audio, procesar la información de audio de cada paquete de audio comprimido almacenado en la memoria intermedia de mezcla de audio con un descodificador de audio para generar muestras de señal de audio digital descomprimidas y utilizar los valores de indicador de calidad de audio digitales para guiar un proceso de mezclado para combinar muestras de señales de audio análogas con las muestras de señal de audio digitales para producir una salida de audio al evitar mezclado innecesario una y otra vez entre análogo y digital si los valores de indicador de calidad de audio digital indican que los paquetes de audio comprimidos se degradan o dañan.
