VIBRATION SIGNAL GENERATING DEVICE AND METHOD, COMPUTER PROGRAM, RECORDING MEDIUM AND SOMESTHETIC SOUND SYSTEM

摘要

This vibration signal generating device (10) generates a vibration signal from an sound signal, and is provided with an extraction means (14) which extracts multiple first frequency components from the sound signal, a determination means (16) which determines whether or not prescribed conditions are fulfilled by the frequency values of multiple second frequency components obtained by converting the multiple first frequency components to frequency components falling within a vibration frequency band, and a generation means (17) which generates, depending on the determination result of the determination means, either (i) a vibration signal that includes the multiple second frequency components, or (ii) a vibration signal that includes one of the multiple second frequency components.
