What is in the textarea box above will work any place on your webpage. Just place the codes wherever you want this audio control to appear.
If you wish to use the embed src code for sound files, this will not work if you put the sound file in between the two <audio></audio> tags. Just use the embed tag by itself, again any where on the page that you want it to show. If you want the sound file to start playing and do not want the control to show, then place the embed src tag in the head of the page.
