Abstract

DISPOSITIVO E MéTODO PARA A GERAçãO DE UM SINAL ESTéREO CODIFICADO DE UMA PEçA DE áUDIO OU FLUXO DE DADOS DE áUDIO. Dispositivo para a geração de um sinal estéreo codificado de uma representação de multicanais inclui um decodificador multicanais (11) gerando três ou mais multicanais a partir de pelo menos um canal básico e de informações paramétricas. Os três ou mais multicanais estão submetidos ao processamento de sinal do fone de ouvido (12) para a geração de um primeiro canal estéreo não codificado e um segundo canal estéreo não codificado que são então enviados a um codificador estéreo (13) para gerar um arquivo estéreo codificado no lado de saída. O arquivo estéreo codificado pode ser reproduzido em qualquer player adequado sob a forma de um CD player ou um hardware player, de maneira que o usuário do player não somente obtenha uma impressão estéreo normal, mas uma impressão multicanais.
