Package fftManager.fftorganiser

Class FFTDataList

java.lang.Object
fftManager.fftorganiser.FFTDataList
public class FFTDataList extends Object
List of FFT Data provided by the FFTDataOrganiser. This should be interleaved by channel and makes a 'friendly' lump of FFT data to use with various localisation algorithms.

  • Constructor Details Link icon

    • FFTDataList Link icon

      public FFTDataList(double sampleRate)
      Construct an FFT data list object.

  • Method Details Link icon

    • addData Link icon

      public boolean addData(FFTDataUnit fftDataUnit)
      Add an FFTDataUnit to the list.
      Parameters:
      fftDataUnit -
      Returns:
      true if all the FFT's are all still the same length.

    • mergeIn Link icon

      public int mergeIn(FFTDataList otherList)
      Merge the other list into this one ....
      Parameters:
      otherList - Other list of FFT data (can be null in which case nothing will happen);
      Returns:
      number of FFT data units added

    • getChannelData Link icon

      public FFTDataUnit[] getChannelData(int iChannel)
      Get the FFT data units for a single channel.
      Parameters:
      iChannel - channel index
      Returns:
      list for a single channel.

    • getChannelSeparatedData Link icon

      public FFTDataUnit[][] getChannelSeparatedData()
      Get all the data separated by channel. The order will be sequential since all the data are being picked by channel map.
      Returns:
      arrays of all data by channel

    • interleaveOK Link icon

      public boolean interleaveOK()
      Check channel ordering is all OK still.
      Returns:
      true if channels correctly interleaved.

    • getFftDataUnits Link icon

      public ArrayList<FFTDataUnit> getFftDataUnits()
      Returns:
      the fftDataUnits

    • getChannelMap Link icon

      public int getChannelMap()
      Returns:
      the channelMap

    • getChannelCount Link icon

      public int[] getChannelCount()
      Returns:
      the channelCount

    • getMinChannelCount Link icon

      public int getMinChannelCount()
      Returns:
      the minChannelCount

    • getMaxChannelCount Link icon

      public int getMaxChannelCount()
      Returns:
      the maxChannelCount

    • getMinFFTLength Link icon

      public int getMinFFTLength()
      Returns:
      the minFFTLength

    • getMaxFFTLength Link icon

      public int getMaxFFTLength()
      Returns:
      the maxFFTLength

    • getSampleRate Link icon

      public double getSampleRate()
      FFTDataList carries it's own sample rate, this is so that it can be easily used with upsampled data during localisation, i.e. the sample rate in the data may no longer be the same as the sample rate in the source of the data !
      Returns:
      the sampleRate in Hz
