Abstract
A music genre judging device able to judge a genre of music in a relatively simple structure. The music genre judging device is provided with a signal input partwhich takes in music reproduction signal outputted from a music reproduction devicea signal processing partwhich outputs 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 taken in by the signal input part; a data generating partwhich takes in the integration value and the differential values outputted from the signal processing partfor each prescribed sampling unit time Tn, judges whether the integration value and the differential value of the low frequency component and the differential value of the high frequency component exceed respective prescribed levels within the sampling unit time Tn, and generates analysis data Dobtained by totalizing numbers of times of judgment when a value exceeding the prescribed level is detected for each prescribed sampling cycle Tm and each of the integration value and the differential values; and a data analysis partwhich calculates respective average values Mto Mof the totalized values and respective coefficients of variation CV, CVof the totalized values, which are described with respect to the respective differential values of the low frequency component and the high frequency component in the analysis data D, and judges a genre of music outputted from the music reproduction device based on the calculation result.
