What is the correct HTML element for playing audio files? code example

Example 1: how do you play audio files on html

<audio src="sound.mp3" autoplay></audio>

Example 2: audio html tag

MIME Types for Audio Formats
Format	MIME-type
MP3		audio/mpeg
OGG		audio/ogg
WAV		audio/wav

If simply audio '<audio>' tag is written then audio controls will not appear on the web page.
and for showing audio controller we need to write controls attribute in audion tag '<audio controls>'.

Example
<audio controls>
  <source src="horse.mp3" type="audio/mpeg">
</audio>
