Assignee: SONY GROUP CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 15:
16. An information processing method, comprising:
in an information processing apparatus:
receiving an input sound that includes a target sound, wherein the target sound is a sound of a target of vibration;
extracting, from a sound signal of the input sound, a partial signal which is a signal in a frequency band corresponding to the target sound;
applying a signal processing operation to the extracted partial signal, wherein the signal processing operation is applied for:
applying a sound pressure change detection processing operation to extract an attack sound signal,
applying a lingering detection processing operation to extract a lingering signal,
combining a first result of the sound pressure change detection processing operation and a second result of the lingering detection processing operation,
executing a pitch shift processing operation to shift a frequency of the extracted partial signal, and
multiplying 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

generating, 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.
