public class SpectralFluxProcessor<T extends AudioBuffer>
extends AbstractFluxProcessor<T>

Computes the spectral flux between two LinearFrequencySpectrum. Flux is defined as some kind of distance between the powers/magnitudes of the spectra. To calculate the distance, a DistanceFunction is used. To create the actual AbstractFluxProcessor.FluxCalculator you can use the provided convenience methods createMagnitudeFluxCalculator(com.tagtraum.jipes.math.DistanceFunction, boolean) and createPowerFluxCalculator(com.tagtraum.jipes.math.DistanceFunction, boolean).
