Abstract

Se describe un método de codificación de audio y un aparato relacionado. El método de codificación de audio incluye: llevar a cabo procesamiento de transformación de tiempo-frecuencia en una señal en el dominio del tiempo de un cuadro de audio actual, para obtener coeficientes espectrales del cuadro de audio actual; adquirir un parámetro de codificación de referencia del cuadro de audio actual; y si el parámetro de codificación de referencia adquirido del cuadro de audio actual satisface una primera condición de parámetro, codificar los coeficientes espectrales del cuadro de audio actual con base en un algoritmo de excitación codificado por transformada, o si el parámetro de codificación de referencia adquirido del cuadro de audio actual satisface una segunda condición de parámetro, codificar los coeficientes espectrales del cuadro de audio actual con base en un algoritmo de codificación por transformada de alta calidad. El método de codificación de audio y el aparato relacionado ayudan a mejorar la calidad de codificación o eficiencia de codificación de codificación de cuadros de audio.
