Abstract
"MéTODOS DE CONSERVAçãO DA INFORMAçãO DE NãO FALA PERCEPTIVELMENTE RELEVANTE EM UM SINAL DE áUDIO DURANTE A CODIFICAçãO DO SINAL DE áUDIO E DE CONSERVAçãO DA INFORMAçãO PERCEPTIVELMENTE RELEVANTE EM UM SINAL DE áUDIO, E, APARELHO PARA USO EM UM CODIFICADOR DE SINAL DE áUDIO" Informação de não fala perceptivelmente relevante pode ser conservada durante a codificação de um sinal de áudio pela determinação de se o sinal de áudio inclui tal informação (122, 124, 125). Se for assim, uma classificação de fala/ruído do sinal de áudio é eliminada (43) para impedir a classificação errada do sinal de áudio como ruído.
