PURPOSE:To actually feel the sense of reality without changing the direction of localized sound image even if a listener changes the direction of a head. CONSTITUTION:When a controller 23 judges that direction change is present by the output of a direction detector 20 provided for a headphone 18, a coefficient data set for changing the sound image localization direction in the opposite direction to the change direction is outputted to DSP 10. DSP 10 executes a prescribed signal processing based on the inputted coefficient data set and moves the sound image localization direction for the headphone 18 in the opposite direction to the change direction of the headphone 18. |
