Play audio on WebGL without clicking on WebGL canvas

To play an audio source on a WebGL canvas without clicking on the canvas, you can use the HTMLAudioElement object to create an audio element and control its playback.

Bellow an example of how you can do this:

// Create an audio element

var audio = new Audio();

// Set the audio source

audio.src = 'path/to/audio.mp3';

// Load the audio

audio.load();

// Play the audio

audio.play();

Alternatively, you can use the Web Audio API to control the audio playback. The Web Audio API provides a number of audio-specific functions and allows you to manipulate audio in more advanced ways, such as applying audio effects, creating audio visualizations, and more.

Here is an example of how you can use the Web Audio API to play an audio source on a WebGL canvas:

// Create an audio context

var audioCtx = new (window.AudioContext || window.webkitAudioContext)();

// Load the audio file

var request = new XMLHttpRequest();

request.open('GET', 'path/to/audio.mp3', true);

request.responseType = 'arraybuffer';

request.onload = function() {

  // Decode the audio data

  audioCtx.decodeAudioData(request.response, function(buffer) {

    // Create a buffer source

    var source = audioCtx.createBufferSource();

    source.buffer = buffer;

    // Connect the source to the audio context destination

    source.connect(audioCtx.destination);

    // Play the audio

    source.start();

  });

};

request.send();
