# Tips-1) What is HTML Audio

The HTML <audio> element is used to play an audio file on a web page.

The <audio> HTML element is used to embed sound content in documents. It may contain one or more audio sources, represented using the src attribute or the <source> element: the browser will choose the most suitable one. It can also be the destination for streamed media, using a MediaStream.

Example of HTML Audio

To play an audio file in HTML, use the <audio> element:

index.html

Example: HTML

<!DOCTYPE html>
<html>
<body>

<audio controls>
  <source src="https://www.w3schools.com/html/horse.ogg" type="audio/ogg">
  <source src="https://www.w3schools.com/html/horse.ogg" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

</body>
</html>
