Abstract

um dispositivo inclui um codificador. o codificador é configurado para receber dois canais de áudio. o codificador também é configurado para determinar um valor de incompatibilidade indicativo de uma quantidade de uma incompatibilidade temporal entre os dois canais de áudio. o codificador é configurado adicionalmente para determinar, com base no valor de incompatibilidade, pelo menos um dentre um canal-alvo ou um canal de referência. o canal-alvo corresponde a um canal de áudio latente dentre os dois canais de áudio e o canal de referência corresponde a um canal de áudio de avanço dentre os dois canais de áudio. o codificador também é configurado para gerar um canal-alvo modificado ajustando-se o canal-alvo com base no valor de desvio. o codificador é configurado adicionalmente para gerar pelo menos um canal codificado com base no canal de referência e no canal-alvo modificado.
