Abstract

codificador e decodificador de áudio para codificar e decodificar amostras de áudio codificador de áudio ( 100) para codificar amostras de áudio, incluindo um codificador de introdução de efeito de dobragem de domínio de tempo (110) para codificar amostras de áudio em um primeiro domínio de codificação, sendo que o primeiro codificador de introdução de efeito de dobragem de domínio de tempo ( 11 o) apresenta uma primeira regra de framing, uma janela de início e uma janela de parada. o codificador de áudio ( 100) inclui ainda um segundo codificador ( 120) para codificar amostras em um segundo domínio de codificação, sendo que o segundo codificador (120) apresenta uma regra de frame diferente. o codificador de áudio (100) inclui ainda um controlador (130) que muda do primeiro codificador (110) para o segundo codificador (120) em resposta à característica das amostras de áudio, e para modificar a segunda regra de framing em resposta à mudança do primeiro codificador (110) para o segundo codificador (120), ou para modificar a janela de início ou a janela de parada do primeiro codificador (110), onde a segunda regra de framing permanece inalterada.
