Abstract
"MéTODO E CODIFICADOR PARA CODIFICAR UM SINAL DE áUDIO DE MULTICANAL, APARELHO PARA FORNECER UM SINAL DE áUDIO, SINAL DE áUDIO CODIFICADO, MEIO DE ARMAZENAMENTO, E, MéTODO E DECODIFICADOR PARA DECODIFICAR UM SINAL DE áUDIO". Sinais de áudio de multicanal são codificados em um sinal de áudio monoaural e informação permitindo recuperar o sinal de áudio de multicanal do sinal de áudio monoaural e a informação. A informação e gerada pela determinação de uma primeira porção da informação para uma primeira região de freq³ências do sinal de áudio de multicanal e pela determinação de uma segunda porção da informação para uma segunda região de freq³ências do sinal de áudio de multicanal. A segunda região de freq³ências é uma porção da primeira região de freq³ências e, desse modo, é uma subfaixa da primeira região de freq³ências. A informação é em multicamadas, permitindo a definição de uma escala da qualidade de decodificação versus taxa de bits.
