You can read about the HTML <audio> tag.
The <audio> tag is fine if you just want to put a playable sound in a web page, but if you want sophisticated control of the sound, other methods are better (see the links below).

Other ways to play audio in a Web page:
Use an HTMLAudioElement as a source AudioNode in WebAudio
Buffer and play a sound in Web Audio
