Abstract
MéTODO PARA SINTETIZAR UM SINAL DE áUDIO MONO BASEADO EM UM SINAL DE áUDIO CODIFICADO DE MúLTIPLOS CANAIS DISPONìVEIS, DECODIFICADOR DE áUDIO, TERMINAL MóVEL, SISTEMA DE CODIFICAçãO, PROGRAMA DE COMPUTADOR, E, CóDIGO DE PROGRAMA A invenção relaciona a um método para sinteizar um sinal de áudio mono baseado no sinal de áudio codificado de múltiplos canais disponíveis. O sinal de áudio codificado de múltiplos canais é assumido para compreender ao menos uma parte de uma banda de freqüência de áudio separada dos valores de parâmetro para cada canal do sinal de áudio de múltiplos canais. Para reduzir a carga de processamento na sintetização do sinal de áudio mono, é proposto que os valores do parâmetro de múltiplos canais sejam combinados ao menos com a parte de uma banda de freqüência de áudio no domínio do parâmentro. Os valores do parâmetro combinados são então usados para sintetizar o sinal de áudio mono.A invenção relaciona igualmente a um decodificador de áudio correspondente, a um sistema de codificação correspondente e a um programa de computador correspondente.
