PURPOSE:To obtain a reproduced sound field stable even at multi-path fading by providing a sound field correction circuit restoring the location of a sound image to the home position again when the position of the sound image is about to change. CONSTITUTION:A part of left and right signal components is given to high pass filters 11, 12 whose cut-off frequency is nearly 3kHz, only the intermediate and high frequency components are inverted by inverting circuits 13, 14 and the result is fed respectively to the right and left signal components. Thus, the inverted phase of the right signal component is fed to the left signal output and the inverted phase of the left signal component is fed to the right signal output. Thus, the inverted component moves the left sound source to the left and the right sound source to the right, and even when the high-cut and blending are applied at multi-path fading so as to generate a stable reproduced sound field. |
