Abstract

resumo do pedido de patente de invenção para: “método e equipamento para a obtenção de coeficientes do espectro para um quadro de substituição de um sinal de áudio, descodificador de áudio, receptor de áudio e sistema para transmissão de sinais de áudio”. abordagem é descrita para obter coeficientes de espectro para um quadro de substituição (m) de um sinal de áudio. um componente tonal de um espectro de um sinal de áudio é detectado com base em um pico que existe nos espectros de quadros anteriores a um quadro de substituição (m). para o componente tonal do espectro, um coeficiente de espectro para o pico (502) e o seu meio exterior no espectro do quadro de substituição (m) é predito, e para o componente não-tonal de espectro, um coeficiente do espectro não-predito para o quadro de substituição (m) ou um coeficiente do espectro correspondente de um quadro anterior ao quadro de substituição (m) é utilizado. fig. 1
