Create an iframe script that plays audio in background (without showing the audio player)

Basically, I need an iframe script that plays audio in the background without showing an audio player or anything like that. so for example the iframe would be something along the lines of this (if you have a better method feel free to use it): but additionally, I want to upload an MP3 to my server and let the iframe play that MP3 autoplay once. (you also need to give me instruction where I should upload the Mp3 once the iframe is done). This should be a matter of minutes for someone who is trained (unlike me).
