Get spectral flux
Description
Internal soundgen function
Usage
getSpectralFlux(s)
Arguments
s |
raw spectrogram (not normalized): rows = frequency bins, columns = STFT frames |
Details
Calculates spectral flux: the average change across all spectral bins from one STFT frame to the next. Spectra are normalized in each frame, so amplitude changes have no effect on flux.
Value
vector of length ncol(s)
