Hide mp3 location to prevent users from downloading

[tobolita]

Im working on an Iphone web, so basically I wont be using any flash players to do that. So I will be using the HTML 5.0 codes.

<audio src="mp3file.mp3" controls autobuffer></audio>

Is there any way to hide the source location? To prevent viewers from downloading it.

I guess Ill be using PHP... Is there any javascript code or others?
I would want PHP as my last and NOT ONLY option to do it, since I have limited access to the server's database, and PHP is not really my area of expertise.

help is appreciated XD

If the browser needs to download it by direct reference there will not be a way to "hide" it from users. This is partially where flash or other embed-ables (yes I made that up...lol) are used. Hulu as an example will not be able to switch over to html5 for serving video because of this and other concerns (such as multiple ad insertion).
