Abstract

PURPOSE:To control the extension and depth of an acoustic image without changing a space of a microphone head and a loudspeaker, by providing a specific correlative function control device in a sound collecting path or a reproducing path of multi-channel. CONSTITUTION:A correlative function control device which does not vary a transmission amplitude frequency characteristic between input/output signals, alternately inverts the relation of lead and lag of phase between each output signal in accordance with a variation of frequency, also is capable of varying not only a coefficient of correlation between each output signal, between -1 and +1, but also a frequency characteristic of the coefficient of correlation, and outputs 2 or more output signals is inserted into an acoustic sound collecting path or a reproducing path of multi-channel. For instance, a correlative function control device consisting of filters 1, 2, 1' and 2' having the same frequency characteristic, delaying circuits 3, 3' having the same delay time characteristic, phase shifting circuits 4, 4', subtracters 5, 8 and adders 6, 7 is inserted into a 2-channel acoustic sound collecting path or reproducing path.
