Abstract

um aparelho e um método para converter um primeiro sinal de áudio espacial paramétrico em um segundo sinal de áudio espacial paramétrico. descreve-se um aparelho (300) para a conversão de um primeiro sinal de áudio espacial paramétrico representando uma primeira posição de escuta ou uma primeira orientação de escuta em uma cena de áudio espacial em um segundo sinal de áudio espacial paramétrico (112, 114) representando uma segunda posição de escuta ou uma segunda orientação de escuta, o aparelho compreendendo: uma unidade de modificação de sinal de áudio espacial (301, 302) adaptada para modificar o primeiro sinal de áudio espacial paramétrico (212, 214) dependente de uma mudança da primeira posição de escuta ou da primeira orientação de escuta de modo a obter o segundo sinal de áudio espacial paramétrico (212, 214), em que a segunda posição de escuta ou a segunda orientação de escuta corresponde à primeira posição de escuta ou à primeira orientação de escuta alterada pela mudança.
