Abstract

Verfahren zum Verbessern einer wahrgenommenen Akustik eines Raumes mit den Verfahrensschritten: Aufnehmen mindestens eines Klangsignals über ein Aufnahmemittel in der Nähe mindestens einer Klangquelle in dem Raum; Durchführen von jeweils einer Faltung des aufgenommenen Klangsignals mit jeweils einer Impulsantwortfunktion zum Erzeugen von unterschiedlichen optimierten Klangsignalen, wobei die jeweilige Impulsantwortfunktion aus einer Auswahl von vorgegebenen Impulsantwortfunktionen für den Raum ausgewählt werden; Wiedergeben der optimierten Klangsignale über in dem Raum angeordnete Klangwiedergabemittel, wobei jedem Klangwiedergabemittel ein unterschiedliches optimiertes Klangsignal zugeführt wird, und wobei jeweils nach einem Umschaltzeitintervall die optimierten Klangsignale den Wiedergabemitteln derart zugeführt werden, dass keinem der Wiedergabemittel in direkt aufeinander folgenden Umschaltzeitintervallen dasselbe optimierte Klangsignal zugeführt wird.
