Abstract
trata-se de um aparelho para gerar uma primeira multiplicidade de sinais de saída com base em pelo menos um sinal-fonte de áudio que compreende uma rede de atraso e um processador de retroalimentação. a rede de atraso compreende uma segunda multiplicidade de trajetos de atraso, em que cada trajeto de atraso tem uma linha de atraso e um filtro de atenuação. cada linha de atraso é configurada para atrasar sinais de saída de linha de atraso e para combinar o pelo menos um sinal-fonte de áudio e um sinal de áudio reverberado para obter um sinal combinado, em que o filtro de atenuação de um trajeto de atraso é configurado para filtrar o sinal combinado a partir da linha de atraso do trajeto de atraso para obter um sinal de saída. a primeira multiplicidade de sinais de saída compreende o sinal de saída. o processador de retroalimentação é configurado para reverberar a primeira multiplicidade de sinais de saída para obter uma terceira multiplicidade dos sinais de áudio reverberados que compreende o sinal de áudio reverberado.
