MUSIC GENRE IDENTIFICATION DEVICE AND GAME DEVICE USING THE SAME

摘要

It is possible to provide a music genre identification device capable of identifying a music genre by using a comparatively simple configuration. The music genre identification device includes: a signal input unit (4) for acquiring a music reproduction signal outputted from a music reproduction device (100); a signal processing unit (10) for outputting an integration value and a differential value of a low-frequency component and a differential value of a high-frequency component of the music reproduction signal inputted to the signal input unit (4); a data generation unit (30) for acquiring the integration value and the differential value outputted from the signal processing unit (10) for a predetermined sampling unit time (Tn) and judging whether the integration value and the differential value of the low-frequency component and the differential value of the high-frequency component exceed a predetermined level within the sampling unit time (Tn) so as to generate analysis data (D1) by accumulating the number of times when a value exceeding the predetermined level is detected for each predetermined sampling cycle (Tm) for the integration values and the differential values, respectively; and a data analysis unit (31) for calculating average values (M0 to M2) of the accumulated values described in the analysis data (D1) and fluctuation coefficients (CV1, CV2) of the differential values of the low-frequency component and the high-frequency component so as to identify the genre of music outputted from the music reproduction device according to the calculation result.
