Abstract

Un codificador de conformidad con la presente descripción incluye una primera unidad de codificación que genera una primera señal codificada en la cual una señal de banda baja que tiene una frecuencia más baja que o igual a una frecuencia predeterminada de una señal de entrada de voz o audio se codifica y una señal decodificada de banda baja; una segunda unidad de codificación que codifica, con base en la señal decodificada de banda baja, una señal de banda alta que tiene una banda más alta que aquella de la señal de banda baja para generar una señal codificada de banda alta; y una primera unidad de multiplexión que multiplexa la primera señal codificada y la señal codificada de banda alta para generar y enviar una señal codificada. La segunda unidad de codificación calcula una relación de energía entre un componente de ruido de banda alta, el cual es un componente de ruido de la señal de banda alta, y un componente no tonal de banda alta de una señal decodificada de banda alta generada a partir de la señal decodificada de banda baja y envía la relación calculada como la señal codificada de banda alta.
