energy property
Energy is a measure from 0.0 to 1.0 and represents a perceptual measure of
intensity and activity. Typically, energetic tracks feel fast, loud, and
noisy. For example, death metal has high energy, while a Bach prelude
scores low on the scale. Perceptual features contributing to this
attribute include dynamic range, perceived loudness, timbre, onset rate,
and general entropy.
