Abstract

Modalidades de la presente invención proporcionan un método de codificación y aparato, los cuales se relacionan con el campo de las comunicaciones y pueden ejecutar una asignación de bits de cuantificación apropiada para coeficientes espectrales de una señal de audio, mejorando así la calidad de una señal obtenida mediante un decodificador por medio de la decodificación; el método incluye: después de dividir los coeficientes espectrales de una trama de datos actual en subbandas, adquirir valores de envoltura de frecuencia cuantificada de las subbandas; modificar valores de envoltura de frecuencia cuantificada de las subbandas de una primera cantidad en las subbandas; asignar bits de cuantificación a las subbandas de acuerdo con los valores de envoltura de frecuencia cuantificada modificados de las subbandas de la primera cantidad; cuantificar un coeficiente espectral de una subbanda a la cual se asigna un bit de cuantificación en las subbandas; y escribir el coeficiente espectral cuantificado de la subbanda a la cual se asigna un bit de cuantificación en una corriente de bits.
