Abstract
trata-se de um método de codificação de áudio e de um aparelho relacionado. o método de codificação de áudio inclui: realizar processamento de transformação de frequência de tempo em um sinal de domínio de tempo de um atual quadro de áudio, a fim de obter coeficientes espectrais do atual quadro de áudio (101); adquirir um parâmetro de codificação de referência do atual quadro de áudio (102); e caso o parâmetro de codificação de referência adquirido do atual quadro de áudio satisfaça uma primeira condição de parâmetro, codificar (103) os coeficientes espectrais do atual quadro de áudio com base em um algoritmo de excitação de transformada codificada ou, caso o parâmetro de codificação de referência adquirido do atual quadro de áudio satisfaça uma segunda condição de parâmetro, codificar (104) os coeficientes espectrais do atual quadro de áudio com base em um algoritmo de codificação de transformada de alta qualidade. o método de codificação de áudio e o aparelho relacionado auxiliam no aprimoramento da qualidade de codificação ou da eficiência de codificação da codificação de quadro de áudio.
