PURPOSE:To define the central normal position of sound image by constructing a sound signal component to be normally positioned at the center while preceding the component to be normally positioned at the other. CONSTITUTION:A left channel sound signal 5 and a right channel sound signal 6 are inputted to a first adder 7. The output is inputted to adders 10/ 11. The left channel signal 5 is delayed by an Lch delay circuit 8. The same amount of delay is supplied to the signal 6 by an Rch delay circuit 9. These sound signals are added from the output of the adder 7 and the adders 10/11 to turned to be sound signals 14/15. These signals 14/15 are selected by selectors 12/13, and inputted through amplifiers 1/2 to speakers 3/4. |
