Constructor Details
- Amplitude
  
  public Amplitude(PApplet parent)
  
  Parameters:
  
  parent - typically use "this"
Method Details
- halfLife
  
  public void halfLife(float value)
  
  Sets the half-life of this amplitude analyzer. The output approaches zero based on the value on halfLife. The default value is 0.1.
- analyze
  
  public float analyze()
  
  Queries a value from the analyzer and returns a float between 0. and 1.
  
  Returns:
  
  amp An amplitude value between 0-1.
- input
  
  public void input(SoundObject input)
  
  Define the audio input for the analyzer.
  
  Overrides:
  
  input in class Analyzer
  
  Parameters:
  
  input - the input sound source. Can be an oscillator, noise generator, SoundFile or AudioIn.
- getModulator
  
  public UnitOutputPort getModulator()
