ACOUSTIC SIGNAL CONVERTER

PROBLEM TO BE SOLVED: To provide a converter of an original acoustic signal which reproduces natural spatial orientation with a headphone or an earphone. SOLUTION: Then acoustic signal after conversion is prevented from being symmetrical even when the original acoustic signal having symmetry is converted by obtaining direct sound and reflected sound from a virtual sound source by simulation, and simultaneously adding a numerical sequence substantially regarded as the random number, of which the average value is 0 and the standard deviation is ≥0.1 msec at arrival time of the reflected sound to a virtual participant thereby giving deviation.
