Class Name

Amplitude

Description

This is a volume analyzer. It calculates the root mean square of the amplitude of each audio block and returns that value.

Examples

  • import processing.sound.*;
    Amplitude amp;
    AudioIn in;
    
    void setup() {
      size(640, 360);
      background(255);
        
      // Create an Input stream which is routed into the Amplitude analyzer
      amp = new Amplitude(this);
      in = new AudioIn(this, 0);
      in.start();
      amp.input(in);
    }      
    
    void draw() {
      println(amp.analyze());
    }
