Abstract

"MéTODO PARA DECODIFICAR UM SINAL DE áUDIO E SISTEMA DE áUDIO PARA OTIMIZAR O FUNCIONAMENTO DE UM PROGRAMA DE áUDIO NA EXTREMIDADE DE USUáRIO". Método para decodificar um sinal de áudio que inclui a recepção de um sinal de áudio digital contendo uma pluralidade de canais (221-226 ou Central, todos os outros auto-falantes) definidos acima, em que um canal da pluralidade de canais é um canal central (C ou Central) e pelo menos um canal da outra pluralidade de canais é um canal de áudio permanente; a comparação do canal central (C ou Central) com pelo menos um canal da outra pluralidade de canais (221-224 ou Todos os outros auto-falantes) ; e o ajuste automático(232, 233) do canal central e de pelo menos um canal da pluralidade de outros canais quando um valor predeterminado para a taxa não for encontrado.
