HTML Audio

Here's a tutorial on HTML audio:

HTML (Hypertext Markup Language) audio is used to embed audio content, such as music or spoken word recordings, into web pages. Audio files can be played back directly in the web page, allowing visitors to listen to the content without having to download it.

To embed an audio file in HTML, you can use the <audio> element. The src attribute is used to specify the URL of the audio file, and the controls attribute is used to add a set of controls, such as play, pause, and volume, to the audio player.

Here's an example of how to embed an audio file in HTML:

<audio src="music.mp3" controls>
  Your browser does not support the audio element.
</audio>

In this example, the <audio> element is used to embed an audio file called "music.mp3", and the text "Your browser does not support the audio element." is displayed if the browser does not support HTML audio. The controls attribute adds a set of controls to the audio player, allowing the user to play, pause, and adjust the volume of the audio.

You can also use the <source> element to specify multiple audio files in different formats, allowing the browser to choose the best format based on its capabilities. For example:

<audio controls>
  <source src="music.mp3" type="audio/mpeg">
  <source src="music.ogg" type="audio/ogg">
  Your browser does not support the audio element.
</audio>

In this example, two audio files are specified using the <source> element. The browser will choose the best format based on its capabilities, and the text "Your browser does not support the audio element." is displayed if the browser does not support HTML audio.

By using HTML audio, you can embed audio content directly in your web pages and enhance the multimedia experience for your website visitors.
