code: public void initialize(final int sampleRate, final int channels, final int frequency, final float parameter)
  	{
  		this.frequency = frequency;
  		this.sampleRate = sampleRate;
  		inArray = new float[channels][HISTORYSIZE];
  		outArray = new float[channels][HISTORYSIZE];
  		clearHistory();
  	}
docs: Call this to initialize. Will set the memory to 0
