Abstract

DISPOSITIVO, MÉTODO OU PROGRAMA DE COMPUTADOR PARA PROCESSAR UMA CENA DE ÁUDIO CODIFICADA USANDO UMA CONVERSÃO DE PARÂMETRO. A presente invenção refere-se a dispositivo (apparatus: aparato: conjunto de dispositivos de hardware e/ou software) para processar uma cena de áudio codificada (130) que representa um campo sonoro relacionado à posição de um ouvinte virtual, a cena de áudio codificada compreendendo informações sobre um sinal de transporte (122) e um primeiro conjunto de parâmetros (112) relacionados à posição de um ouvinte virtual compreende um conversor de parâmetros (110) para converter o primeiro conjunto de parâmetros (112) em um segundo conjunto de parâmetros (114) relacionado a uma representação de canal que compreende dois ou mais canais para uma reprodução em posições espaciais predefinidas para os dois ou mais canais e uma interface de saída (120) para gerar uma cena de áudio processada (124) usando o segundo conjunto de parâmetros e a informação sobre o sinal de transporte (122).
