Examples |
    import processing.sound.*;
    Sound s;

    void setup() {
      size(200, 200);

      // Play two sine oscillators with slightly different frequencies for a nice "beat".
      SinOsc sin = new SinOsc(this);
      sin.play(200, 0.2);
      sin = new SinOsc(this);
      sin.play(205, 0.2);

      // Create a Sound object for globally controlling the output volume.
      s = new Sound(this);
    }

    void draw() {
      // Map vertical mouse position to volume.
      float amplitude = map(mouseY, 0, height, 0.4, 0.0);

      // Instead of setting the volume for every oscillator individually, we can just
      // control the overall output volume of the whole Sound library.
      s.volume(amplitude);
    }
Description | Set the overall output volume of the Processing sound library.
Syntax |
    .volume(volume)
Parameters |
volume | float: the desired output volume, normally between 0.0 and 1.0 (default is 1.0)
