An apparatus and method for generating audio output signals having a specified cross-correlation relationships is disclosed. The apparatus operates by phase-shifting different frequency bands of an input signal by differing amounts which depend on the desired cross-correlation. The amplitude spectrum of the input signal is not altered.
