TLDR

Put a visual audio player on your page using the <audio> tag and controls attribute:

<audio controls src="audio.mp3"></audio>

Simply replace audio.mp3 with your audio file's URL.

Here's a JavaScript quick-fix:

new Audio('file.mp3').play();

Remember to trigger this on a user interaction such as a button click due to browser autoplay rules.

JavaScript control for audio playback

HTMLAudioElement: A way to communicate with your audio

To gain more control over your audio file with JavaScript use HTMLAudioElement:

var audio = new Audio('file.mp3'); audio.play();

This interface lets you manipulate your audio playback like pause, stop and adjusting the volume.

Leverage howler.js for advanced audio management

Looking for a library with advanced audio capabilities? Try howler.js:

<script src="https://cdn.jsdelivr.net/npm/howler"></script>

Create a Howl class sound object:

var sound = new Howl({ src: ['sound.mp3'], volume: 0.5, // Haven't had your coffee yet? Reduce volume to half. }); sound.play(); // Let the party begin!

Controlling your audio player with JavaScript

Create event listeners to control various aspects of audio playback:

document.getElementById('playButton').addEventListener('click', function() { var audio = document.getElementById('myAudio'); audio.play(); // Who needs Spotify when you have JS? });

###Explore the wonderland of Web Audio API

For audio synthesis and real-time effects, try the Web Audio API. HTML5Rocks offers a detailed guide:

Cross-browser audio with SoundManager 2

Ensure maximum coverage across browsers (yes, even legacy ones) with SoundManager 2. HTML5 is the default audio provider with a reliable Flash fallback option:

soundManager.setup({ url: '/path/to/swf-files/', onready: function() { var mySound = soundManager.createSound({ id: 'aSound', url: 'audio.mp3' }); mySound.play(); // Never underestimate the power of Flash! } });

Streamline your audio interactions with jQuery

Make your audio-related events more concise with jQuery:

$('#audioElement').trigger('play'); // Play audio, the jQuery way.

Handle tricky parts like dynamic audio playlists and smooth transitions using jQuery's animate() and helper functions.

Managing dynamic audio playlists

Enhance user experience by creating dynamic playlists and handling transitions using libraries we've discussed above. Remember: sudden autoplay is considered a bad practice by modern browsers, so always require user interaction.
