Below examples illustrate the p5.setVolume() function in JavaScript:
Example 1: In this example, we set the fixed volume in the code which is 0.5.

javascript

var sound; 
 
function preload() { 
 
    // Initialize sound 
    sound = loadSound("pfivesound.mp3"); 
} 
 
function setup() { 
 
    // Playing the preloaded sound 
    sound.play();
    //stopping the played sound after 5 seconds
    sound.setVolume(0.5);
}

javascript

var sound; 
var slider;
 
function preload() { 
  
    // Initialize sound 
    sound = loadSound("pfivesound.mp3"); 
} 
  
function setup() { 
  
    // Playing the preloaded sound 
    sound.play();
    //creating sound rocker
    slider = createSlider(0, 1, 0.2, 0.2);
  
} 
  
function draw() {
    sound.setVolume(slider.value());
}
