1. An information processing apparatus, comprising:
a central processing unit (CPU) configured to:
receive an input sound that includes a target sound, wherein the target sound is a sound of a target of vibration;
extract, from a sound signal of the input sound, a partial signal which is a signal in a frequency band corresponding to the target sound;
apply a signal processing operation to the extracted partial signal, wherein the signal processing operation is applied to:
apply a sound pressure change detection processing operation to extract an attack sound signal,
apply a lingering detection processing operation to extract a lingering signal,
combine a first result of the sound pressure change detection processing operation and a second result of the lingering detection processing operation,
execute a pitch shift processing operation to shift a frequency of the extracted partial signal, and
multiply a third result of the pitch shift processing operation with a fourth result of the combination of the first result and the second result; and
generate, based on the application of the signal processing operation, a vibration signal representing the vibration having a frequency different from a frequency of the input sound, wherein
the vibration signal is generated at a time of output of the vibration, and
the vibration is outputted in response to the received input sound.
