  • Constructor Details

    • RandomToneGenerator

      public RandomToneGenerator(double minFreq, double maxFreq, int nPolyPoints, Double maxSweepOctaves)
      Make a random tone generator
      Parameters:
      minFreq - minimum frequency
      maxFreq - maximum frequency
      nPolyPoints - number of random polynomial points.
      maximum - sweep for any single sound. If this is null, then other 'points' can use the full frequency range.

    • RandomToneGenerator

      public RandomToneGenerator(double minFreq, double maxFreq, int nPolyPoints)
      Make a random tone generator. Frequencies will be totally unconstrained within the set limits.
      Parameters:
      minFreq - minimum frequency
      maxFreq - maximum frequency
      nPolyPoints - number of random polynomial points.

    • RandomToneGenerator

      public RandomToneGenerator(QADistribution[] freqeuncyDistributions, String name)
      Make a random tone generator with distributions pulled from the list of distributions
      Parameters:
      freqeuncyDistributions - list of frequency point distributions

    • generateSound

      public QASound generateSound(long sourceSample, double sampleRate, double[] delays, double[] amplitudes)
      Description copied from class: QASoundGenerator
      Generate a sound
      Overrides:
      generateSound in class StandardSoundGenerator
      Parameters:
      sourceSample - the sample number at which the source was generated
      sampleRate - sample rate of data to receive the sound
      delays - delays in samples from generation of the sound to it's reception on each hydrophone
      amplitudes - amplitudes on a linear scale (notDB) which incorporates the system full scale and the spreading loss but doesn't yet contain frequency dependent attenuation.
      Returns:
      a generated sound.
