The HTML <audio> tag is a key element used to embed audio content into web pages. It allows developers to easily include audio files such as music, podcasts, or sound effects, providing users with a multimedia-rich experience. The <audio> tag supports multiple audio formats and can be controlled through built-in attributes such as play, pause, volume control, and more. With its cross-browser compatibility and simplicity, the <audio> tag is an essential component in modern web development for delivering audio content.
Syntax of the HTML <audio> Tag
<audio controls>
<source src="audio-file.mp3" type="audio/mpeg">
Your browser does not support the audio tag.

The <audio> element typically contains one or more <source> tags, which specify the different formats of the audio file. The controls attribute adds built-in audio controls like play, pause, and volume adjustment for user interaction.

Examples of HTML <audio> Tag
Example 1: Basic Audio Element with Controls
This is a simple example of embedding an audio file with playback controls.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Basic Audio Example</title>
</head>
<body>
<h2>Listen to the audio clip:</h2>
<audio controls>
<source src="audio-file.mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
</body>
</html>
In this example, the user can play, pause, and adjust the volume of the audio file using the provided controls.
Example 2: Autoplay and Loop Audio
This example demonstrates an audio file that plays automatically when the page loads and loops continuously.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Autoplay and Loop Audio</title>
</head>
<body>
<h2>Automatically Playing Audio:</h2>
<audio src="audio-file.ogg" autoplay loop>
Your browser does not support the audio element.
</audio>
</body>
</html>
Here, the audio starts automatically and loops indefinitely without requiring user interaction.
