Syntax

public static class AcousticEntropy

Methods

CalculateEntropyOfSpectralPeaks(Double[,], Int32, Int32)

CALCULATES THE ENTROPY OF DISTRIBUTION of maximum SPECTRAL PEAKS. Only spectral peaks between the lowerBinBound and the upperBinBound will be included in calculation.

Declaration

public static double CalculateEntropyOfSpectralPeaks(double[, ] amplitudeSpectrogram, int lowerBinBound, int upperBinBound)

Parameters

Type	Name	Description
Double[,]	amplitudeSpectrogram
Int32	lowerBinBound
Int32	upperBinBound

Returns

Type	Description
Double

CalculateSpectralEntropies(Double[,], Int32, Int32)

Calculates three SUMMARY INDICES - three different measures of spectral entropy. Each of them is derived from the frames of the passed amplitude spectrogram.

1. the entropy of the average spectrum.
2. the entropy of the variance spectrum.
3. the entropy of the Coeff of Variation spectrum.

Declaration

public static Tuple<double, double, double> CalculateSpectralEntropies(double[, ] amplitudeSpectrogram, int lowerBinBound, int reducedFreqBinCount)

Parameters

Type	Name	Description
Double[,]	amplitudeSpectrogram	matrix.
Int32	lowerBinBound	lower bin bound to be included in calculation of summary index.
Int32	reducedFreqBinCount	total bin count to be included in calculation of summary index.

Returns

Type	Description
Tuple<Double, Double, Double>	two doubles.

CalculateTemporalEntropySpectrum(Double[,])

Declaration

public static double[] CalculateTemporalEntropySpectrum(double[, ] spectrogram)

Parameters

Type	Name	Description
Double[,]	spectrogram

Returns

Type	Description
Double[]
