Abstract

SISTEMA PARA GERAR ELETRONICAMENTE UMA FORMA DE ONDA DE REVERBERAçãO ARTIFICIAL A PARTIR DE UMA FORMA DE ONDA DE ENTRADA E PRODUTO DE PROGRAMA DE COMPUTADOR. Um sistema de reverberação eletrónica emprega um processador para produzir uma pluralidade de amostras de atraso que são adicionadas a um sinal direto para produzir som reverberante. O sistema exposto gera ou emprega uma lista de pares de valor de ganho que são produzidos baseado em ajustes de controle ou são providos como coeficientes fixos. O processador gera amostras de reverberação aplicando estes coeficientes a amostras de atraso e somando suas amplitudes para produzir amostras de forma de onda de reverberação. As amostras de forma de onda de reverberação são adicionadas ao sinal direto.
