Abstract

trata-se de um método e um aparelho de codificação de áudio. o método inclui: determinar a dispersão de distribuição, em espectros, de energia de n quadros de áudio de entrada (101), em que os n quadros de áudio incluem um quadro de áudio atual e n é um número inteiro positivo; e determinar, de acordo com a dispersão de distribuição, nos espectros, da energia dos n quadros de áudio, se deve ser usado um primeiro método de codificação ou um segundo método de codificação para codificar o quadro de áudio atual (102), em que o primeiro método de codificação é um método de codificação que tem base em transformada de frequência de tempo e quantização de coeficiente de transformada e que não tem base em previsão linear e o segundo método de codificação é um método de codificação com base em previsão linear. de acordo com o método, quando um quadro de áudio for codificado, a dispersão de distribuição, em um espectro, de energia do quadro de áudio é considerada, o que pode reduzir a complexidade de codificação e garantir que a codificação seja de precisão relativamente alta.
