PURPOSE:To extract a reflected sound by projecting a reflected sound obtained by measurement or calculation on a plane formed of reproducing speakers and a listener and dividing the projected reflected sound into reflected sounds so that they are put together as virtual sound images. CONSTITUTION:Reflected sounds obtained outside by the measurement or simulation by a sound line method, etc., are inputted from a 1st input terminal 6 and stored in a storage means 1. A projecting means 2 projects the reflected sounds stored in the storage means 1 on the plane formed of speakers 9, 10, 11, and 12 and the listener 13. Then an arithmetic means 3 divides the reflected sounds which are projected as mentioned above so that they are put together as the virtual sound images. The four reflected sounds which are divided and found are set in a sound field controller 5 by a setting means 4. The sound field controller 5 convolutes series of the four reflected sounds with the musical sound signal inputted to a 2nd input means 7 and outputs the results from corresponding speakers. |
