audio in wordpress

Hello everyone,
These days I’m building a new WordPress site and looking for a solution for sound- audio.
Even though the issue sound in web pages is controversial, this site is a definite need.

According to requirement, the sound should be played from the first page and continue the rest of the pages without having to stop.

one known solution is to create a iframe – but I do not want the whole site will be in the frame and the sound is the one that contains it.

Another option, less charming me she mix pop-up a new window to play sound, and the STOP button will override the pop-up window.

I started reading the html5 audio tag and I thought, maybe we can save the audio in memory of the browser?

Looking for ways, ethical!, happy in each direction you have…

Thanks in advance,
Josef Dalal.
