Abstract

Dispositif de réverbération électronique, comportant un amplificateur d'entrée 1, suivi d'un dispositif de retard 2 puis d'un amplificateur de sortie 3 et un trajet de rétroaction 4 entre une sortie de l'amplificateur de sortie et une entrée de l'amplificateur d'entrée. Le dispositif de retard 2 est une ligne à retard variable, ajustable par un régulateur 5. Un dispositif de commande 6, 7, 8 relié à la sortie de l'amplificateur d'entrée 1 contrôle le régulateur 5 de sorte que la somme du signal issu du dispositif de retard et réappliqué à l'amplificateur d'entrée par le trajet de rétroaction, et du signal d'entrée initial de l'amplificateur d'entrée soit sensiblement indépendante de la fréquence. Application notamment à la création d'effets d'écho.
