Abstract:
A sound signal processing method according to an embodiment includes a step of acquiring an input sound signal, a step of acquiring a beat number per unit time period from the input sound signal, a step of normalizing the input sound signal with the beat number per unit time period, a step of calculating a beat spectrum of the normalized input sound signal, and a step of calculating a rhythm similarity between the beat spectrum of the normalized input sound signal and a normalized beat spectrum calculated from a reference sound signal.

Claim (Index 7):
The sound signal processing apparatus according to  claim 6 , wherein:\n the information processing apparatus having a first similarity calculation unit and an integration unit; the first similarity calculation unit being configured to calculate a second similarity between the input sound signal and the reference sound signal using nonnegative matrix factorization; and the integration unit being configured to integrate the rhythm similarity and the second similarity.
