Vibration signal generating apparatus and method, computer program, recording medium as well as the experience sound system

摘要

vibration signal generating device (10) includes calculating a generation means for generating an oscillating signal from the acoustic signal (11), the vibration change point time variation of a point on a predetermined variation perfect time axis acoustic signal and calculating means for (12), correction means for performing correction processing of the amplitude of the vibration signal of the immediately preceding corrects the oscillating signal to be smaller than the amplitude of the vibration signal immediately after the vibration changing point of the vibration change point (13) , (i) based on the characteristics of the harmonic components included in the acoustic signal of the vibration change point, and determines whether or not to perform correction processing in the vibration change point, if it is determined to perform (ii) correction process and a control means for controlling the correction means to perform correction processing (14).
