Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Mischen von Tonsignalen. Um dabei mit möglichst geringem technischem Aufwand eine möglichst natürliche Wiedergabe von Tonsignalen über eine Mehrzahl Lautsprecher zu erreiochen, wenn eine dazu abweichende Zahl Schallquellen vorliegt, soll jedes Tonsignal aufgeteilt und wahlweise verzögert, jedes aufgeteilte und wahlweise verzögerte Tonsignal wahlweise gewichtet und mit entsprechenden weiteren Tonsignalen zu einem Zwischensignal (1 bis K) addiert werden. Dann wird jedes Zwischensignal aufgeteilt, gefiltert und anschliessend mit den anderen Zwischensignalen summiert und die summierten Zwischensignale ergeben zusammen ein Ausgangssignal für einen Lautsprecher.
