Abstract
A filter network for use with an acoustic signal reproduction system having at least two, spatially separable, speaker means each capable of reproducing acoustic waves from corresponding electrical signal. The network includes a frequency divider for separating an electrical signal representative of acoustic waves into first and second components, the first component including primarily those audio frequencies, which when acoustically reproduced tend to provide unambiguous binaural phase localization. The second component includes primarily those audio frequencies which when acoustically reproduced tend not to provide unambiguous binaural phase localization. The network also includes structure for delaying the first component for a predetermined period of time to produce a delayed signal so that when the combined first and second components are applied to one of the speaker means and the combined second component and the delayed signal are applied to the other of the speaker means the acoustic field produced tends to simulate spaciousness or ambience of a larger room than the actual listening area.
