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 6):
A sound signal processing apparatus comprising:\n an information processing apparatus having an acquisition unit, a beat number acquisition unit, a normalization unit, a beat spectrum calculation unit and a rhythm similarity calculation unit; the acquisition unit being configured to acquire an input sound signal; the beat number acquisition unit being configured to acquire a beat number per unit time period from the input sound signal; the normalization unit being configured to normalize the input sound signal with the beat number per unit time period; the beat spectrum calculation unit being configured to calculate a beat spectrum of the normalized input sound signal; and the rhythm similarity calculation unit being configured to calculate a rhythm similarity between the beat spectrum of the normalized input sound signal and a normalized beat spectrum calculated from a reference sound signal.
