WebBand energy ratio (BER)—This feature gives a comparison of energy between the higher and lower frequency bands [11]. It basically gives a measure of how dominant low frequencies are. Band energy ratio for a frame t is computed using Eq. (10.4). It has many applications in speech discrimination and audio classification problems. Webband (first dimension). hop_length : int > 0 number of audio samples between successive onset measurements win_length : int > 0 length of the onset autocorrelation window (in …
