Abstract

resumo da patente de invenção para: "descodificador, codificador e método de estimativa informada da percepção sonora empregando sinais de objetos de áudio de bypass em sistemas de codificação de áudio baseada em objetos". é apresentado um descodificador para gerar um sinal de saída de áudio que compreende um ou mais canais de saída de áudio. o descodificador compreende um interface receptor (110) para receber um sinal de entrada de áudio, que compreende uma pluralidade de sinais de objetos de áudio, para receber informação de percepção sonora nos sinais de objetos de áudio e para receber informação de representação que indica se um ou mais sinais de objetos de áudio deverão ser amplificados ou atenuados. além disso, o descodificador compreende um processador de sinal (120) para gerar um ou mais canais de saída de áudio do sinal de saída de áudio. o processador de sinal (120) está configurado para determinar um valor de compensação de percepção sonora dependendo da informação de percepção sonora e dependendo da informação de representação. além disso, o processador de sinal (120) está configurado para gerar um ou mais canais de saída de áudio do sinal de saída de áudio a partir do sinal de entrada de áudio, dependendo da informação de representação e dependendo do valor de compensação de percepção sonora. um ou mais sinais de objetos de áudio de bypass são empregues para gerar o sinal de saída de áudio. além disso é apresentado um descodificador.
