Why should we use controls in the audio element?

Answer 1

It displays audio controls such as play, pause and volume.

Answer 2

its makes easy for user to stop, pause and play audio with a single touch(pause, play buttons) ... and its better to have controls at one place or it becomes clumsy when we put audio with other stuffs like images, text, headers, nav, etc.

Answer 3

you can hidden it with <element hidden> what you want to hide </element>
