Syntax

public static class PowerSpectralDensity

Methods

GetEnergyValues(Double[,])

Square the FFT coefficients >> this gives an energy spectrogram. MatrixTools.SquareValues is doing the same!.

Declaration

public static double[, ] GetEnergyValues(double[, ] fftCoefficients)

Parameters

Type	Name	Description
Double[,]	fftCoefficients

Returns

Type	Description
Double[,]

GetPowerSpectrum(Double[,])

Take average of the energy values in each frequency bin to obtain power spectrum or PSD. SpectrogramTools.CalculateAvgSpectrumFromEnergySpectrogram is doing the same!.

Declaration

public static double[] GetPowerSpectrum(double[, ] energySpectrogram)

Parameters

Type	Name	Description
Double[,]	energySpectrogram

Returns

Type	Description
Double[]
