Spectral rolloff is defined as the frequency κt below which a certain fraction of the total energy is contained. 95 ). 85 ∗ n=1 A nt . 3) n=1 Spectral rolloff estimates the amount of high frequency in the signal. It is another measure of the spectral shape.
It can be observed that songs of high arousal are associated with strong and fast beats. (Data from E. Pampalk Proc. Int. Cont. Music Information Retrieval, 2004) which is computed based on the algorithm described by Klapuri . Here the term onset refers to the starting time of each musical event (note). See  for a tutorial on onset detection in music signals. Rhythm regularity and rhythm clarity are computed by performing autocorrelation on the onset detection curve. If a music segment has an obvious and regular rhythm, the peaks of the corresponding autocorrelation curve will be obvious and strong as well.
3). A more popular emotion taxonomy is to categorize emotions to the four emotion classes: happy, angry, sad, and relaxing, partly because they are related to the basic emotions studied in psychology and partly because they cover the four quadrants of the two-dimensional valence-arousal plane .
