    • 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
      peakToSteal - peak number to steal (there will only be one of these).
      newNumber - new slice number (may be smaller)

    • 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 Details

    • 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

    • getStartSample

      public long getStartSample()

    • getSliceNumber

      public int getSliceNumber()

    • getSliceLength

      public int getSliceLength()

    • getnPeaks

      public int getnPeaks()

    • getPeakInfo

      public int[][] getPeakInfo()
      Peak info is an n x 3 array of bin numbers for an FFT slice. Normally in a whistle, n=1, but there may be multiple peaks in a branched whistle in which case n will be higher. the 3 numbers for each peak are the low, peak and high bins of the contour.
      Returns:
      peak information.

    • getFftDataUnit

      public FFTDataUnit getFftDataUnit()
      Returns:
      the fftDataUnit associated with this slice

    • getUsefulBinRange

      public int[] getUsefulBinRange()
      Get a two element array of useful bin ranges following the convention used in the FFTDataUnit.getUsefulBinRange() whereby the upper limit is one greater than the actual used bin.
      Returns:
      bin range for future calculations
