    getFilterDelay()
    Gets the delay of the filter - rarely used, but can be important for some processing tasks.
    void
    prepareFilter()
    Calculates the poles and zeros for the filter and sets up any memory buffers required during real time operation.
    double
    runFilter(double aData)
    Runs the filter on a single data value
    void
    runFilter(double[] inputData)
    Runs the filter on an array of data

  • Method Details

    • getFilterDelay

      public int getFilterDelay()
      Description copied from interface: Filter
      Gets the delay of the filter - rarely used, but can be important for some processing tasks. For an IIRF filter, this would be half the number of poles, for a moving average or median filter it would be half the filter length.
      Specified by:
      getFilterDelay in interface Filter
      Returns:
      filter delay in samples.

    • prepareFilter

      public void prepareFilter()
      Description copied from interface: Filter
      Calculates the poles and zeros for the filter and sets up any memory buffers required during real time operation.
      Specified by:
      prepareFilter in interface Filter

    • runFilter

      public void runFilter(double[] inputData)
      Description copied from interface: Filter
      Runs the filter on an array of data

      New values overwrite the old values in the array.

      Specified by:
      runFilter in interface Filter

    • runFilter

      public void runFilter(double[] inputData, double[] outputData)
      Description copied from interface: Filter
      Runs the filter on an array of data

      New values write into the output data array.

      Specified by:
      runFilter in interface Filter

    • runFilter

      public double runFilter(double aData)
      Description copied from interface: Filter
      Runs the filter on a single data value
      Specified by:
      runFilter in interface Filter
      Returns:
      New data value
