ABSTRACT:
In known audio equalization systems, full room equalization cannot be employed because it introduces undesirable transient effects during the growth stage of a sound field, especially in a large auditorium. The invention seeks to solve this problem by establishing an initial state of the equalizing system giving a reduced degree of equalization whenever a signal commences but which effects a transition to normal equalization within a time typically of the order of some tens of milliseconds.
