  // Example 20-5: Live Input with Sonia
  
  // Import the Sonia library
  import pitaru.sonia_v2_9.*;
  
  void setup() {
    size(200,200);
    smooth();
    Sonia.start(this);

    // All functions for sound input are static, meaning they are called from the class name itself, LiveInput, rather than an object instance.
    LiveInput.start(); 
    
  }
