成果简介	NOVELTY - The method involves receiving an audio signal containing a musical work from an external database by a computing device. The received audio signal is processed by the computing device using a fast Fourier transform (FFT) to obtain grouped frequencies of the processed audio signal. Frequencies are obtained corresponding to electrical oscillations of the rhythms of the brain by pairwise addition of the values of the frequency sums. Percentage ratio of psycho-emotional background of processed musical work is calculated for each frequency. Emotional characteristics of a musical work are calculated at a given moment in time by calculating arithmetic mean of the values of frequencies. Metadata of a musical work is obtained. The metadata is transferred to the database with subsequent storage. The metadata is transmitted to a user's computing device of a list of musical works sorted by different degrees of emotion. USE - Method for determining spectrum of sound signals.
