Spectral flux
text:
Spectral flux is a measure of how quickly the power spectrum of a signal is changing, calculated by comparing the power spectrum for one frame against the power spectrum from the previous frame. More precisely, it is usually calculated as the L2-norm between the two normalised spectra. Calculated this way, the spectral flux is not dependent upon overall power, nor on phase considerations. The spectral flux can be used to determine the timbre of an audio signal, or in onset detection, among other
