Constructor Detail

SliceData

protected SliceData(int sliceNumber,
                    int sliceLength,
                    FFTDataUnit fftDataUnit)

Constructor to use when creating new slices during initial detection

Parameters:

sliceNumber - slice number

sliceLength - slice length

fftDataUnit - reference to FFT Data Unit.

SliceData

protected SliceData(SliceData oldSlice,
                    int peakToSteal)

Constructor to use when creating slices from a mother slice during whistle fragmentation.

Parameters:

oldSlice - reference to slice in mother shape

newNumber - new slice number (may be smaller)

peakToSteal - peak number to steal (there will only be one of these).

SliceData

protected SliceData(int sliceNumber,
                    long startSample,
                    int[][] peakInfo)

Constructor for creating slices offline when read back from binary files.

Parameters:

sliceNumber - slice nukber

peakData - peak data (n*4)

Method Detail

getPeakBin

public int getPeakBin()

condenseInfo

protected int[] condenseInfo(SliceData prevSlice)

Repacks the data and returns the lower and upper bounds.

0th = lower bound

1st = peak value

2nd = upper bound

3rd = peak number in previous slice (filled in later but allocated now)

Returns:

bounds

getRmsAmplitude

public double getRmsAmplitude()

setRmsAmplitude

public void setRmsAmplitude()

getTotalRMSAmplitude

protected double getTotalRMSAmplitude()

work out the total rms amplitude in all set peaks within the slice Must be called after condenseInfo

findOverlappingPeak

private int findOverlappingPeak(int[] peakInfo,
                                SliceData otherSlice)

countRegions

private int countRegions()

getStartSample

public long getStartSample()
