PURPOSE:To improve a sound field sensation by clearly setting the sound field normal position of a center sound from right-and-left sounds, in a sound field reproducer which reproduces two right-and-left original sound signals at three channels. CONSTITUTION:A left signal L and a right signal R are added by an adding circuit 3, and a signal attenuated by a 1/2 attenuating circuit 10 is outputted as a center signal C to a center speaker 8. Then, residual signals obtained by subtracting the center signal C from the left signal L and the right signal R are outputted to a left speaker 7 and a right speaker 9. |
