Audio.setVolume()

The setVolume() method is used to set the volume of an Audio object in the Three.js library. The Audio object represents an audio file that can be played in a Three.js scene.

Syntax

audio.setVolume( volume )

• audio - The Audio object whose volume is to be set.
• volume - A number between 0 and 1 that represents the new volume for the Audio object. A value of 0 will completely mute the audio, while a value of 1 will set the volume to maximum.

Example

var listener = new THREE.AudioListener();
var sound = new THREE.Audio( listener );
var audioLoader = new THREE.AudioLoader();
audioLoader.load( 'sounds/song.mp3', function( buffer ) {
    sound.setBuffer( buffer );
    sound.setLoop( true );
    sound.setVolume( 0.5 );
    sound.play();
});

In this example, an Audio object is created and loaded with a song file using the AudioLoader object. The setVolume() method is then used to set the volume of the sound object to 50% (0.5).

Notes

• The volume of an Audio object can be changed at any time using the setVolume() method.
• The setVolume() method does not affect the volume of the computer or device playing the audio. It only affects the volume of the Audio object within the Three.js scene.
• The setVolume() method can be used to fade in or out an Audio object by gradually increasing or decreasing the volume over time.
