You might see <audio> Element reference while reading someone else’s HTML, or need it while building a page of your own. Instead of memorizing a definition, look at a working example and see when the element makes sense.

The Idea in Plain English


Embeds audio. controls supplies the browser player; sources offer alternative formats and text gives fallback guidance.

For a reference page, pay attention to where the element is allowed, whether it needs a closing tag, and what other elements it can contain.

A Working Example


Read the sample once before copying it. Notice the element names and attribute values, then compare them with the explanation below.

<audio controls preload="metadata">
    <source src="lesson.ogg" type="audio/ogg">
    <source src="lesson.mp3" type="audio/mpeg">
    Your browser cannot play the audio.
</audio>

What Each Part Does


  • The audio element provides an audio player when a compatible source exists.
  • A source offers an alternative file for a media element or picture.
  • src points to the asset the browser should load.
  • type chooses the relevant kind of script, input, media or embedded object.

A native audio player appears if a supported source loads.

Try It Yourself


Try replacing the example content with your own while keeping the valid HTML structure.

Common Beginner Mistakes


  • Autoplaying unexpected sound or forgetting a transcript for spoken content.
  • Changing several parts of the example at once, making it difficult to see which part caused a different result.
  • Choosing a tag only because its default appearance looks right, without checking whether it describes the content correctly.

Key Takeaways


  • Embeds audio. controls supplies the browser player; sources offer alternative formats and text gives fallback guidance.
  • A native audio player appears if a supported source loads.
  • Test the markup in a browser, and check accessibility and real-world behavior where relevant.
