how to embed audio in html

<audio controls>
  <source src="name.mp3" type="audio/mp3" />
</audio>

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>
