Abstract

resumo codificador de objeto de áudio, decodificador de objeto de áudio, método para a codificação de objeto de áudio, método para a decodificação de objeto de áudio, e produto de programa de computador a presente invenção descreve um codificador de objeto de áudio compreende um receptor (701) que recebe n objetos de áudio. um downmixer (703) faz o downmix dos n objetos de áudio para os m canais de áudio, e um circuito de canal (707) obtém k canais de áudio dos m canais de áudio, k= 1, 2 e k<m. um circuito de parâmetros (709) gera parâmetros upmix de objetos de áudio para pelo menos parte de cada um dos n objetos de áudio relativos aos k canais de áudio e um circuito de saída (705, 711) gera um fluxo de dados de saída compreendendo os parâmetros upmix de objetos de áudio e os m canais de áudio. um decodificador de objeto de áudio recebe o fluxo de dados e inclui um circuito de canal (805) para a obtenção de k canais de áudio do downmix do canal m; e um decodificador de objetos (807) para gerar pelo menos parte de cada um dos n objetos de áudio pelo upmix dos k canais de áudio com base nos parâmetros upmix de objetos de áudio. a invenção pode permitir melhor codificação de objetos mantendo a compatibilidade para trás.
