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

void draw() {
  background(255,120,0);
  
  // Get the overall volume (between 0 and 1.0)
  float level = LiveInput.getLevel();
  fill(200);
  stroke(50);
  
  // Draw an ellipse with size based on volume
  ellipse(width/2,height/2,level*200,level*200); 
}

// Close the sound engine
public void stop() {
  Sonia.stop();
  super.stop();
}
