ABSTRACT:
In a sound image creating apparatus, a distance computation section computes intermediate positions of a moving point along a trajectory line from a movement start position to a movement end position, and further computes a variable distance between each of the intermediate positions of the moving point and a fixed point. A velocity computation section computes a variable velocity of the moving point relative to the fixed point along the time axis on the basis of the variable distance. A signal processing section attenuates or delays an input sound signal in accordance with the variable distance, and varies a pitch of the input sound signal on the basis of the variable velocity, thereby creating the sound image of the input sound signal along the time axis based on principle of Doppler effect.
