Abstract
The present invention includes producing a first processed signal which localizes sound image at a first localization position and a second processed signal which localizes sound image at a second localization position; multiplying one of the first and the second processed signals by a coefficient k which varies in the range of 0 to 1; multiplying the other signal by a coefficient 1−k; and adding the processed signal multiplied by the coefficient k and the processed signal multiplied by the coefficient 1−k. When the predetermined position is located away at an angle &thgr; in a circumferential direction from the front of the listener, the first localization position is in the vicinity of the predetermined position and located away at an angle &thgr; in a circumferential direction from the front of the listener wherein &thgr; <&thgr;, and the second localization position is in the vicinity of the predetermined position and located away at an angle &thgr; in a circumferential direction from the front of the listener wherein &thgr; >&thgr;.
