I need help to find out if i need a copy of Auditon.

You can use them in a production of yours without any licence. The only thing you can't do is distribute any of the sounds on their own - they have to be part of a production. If you wade through the EULA you will find the relevant section, and it says this:

3.6 Content Files. "Content Files" means Adobe assets provided as part of the Services and Software. Unless documentation or specific licenses state otherwise, we grant you a personal, non-exclusive, non-sublicensable, and non-transferable license to use the Content Files to create your end use (i.e., the derivative application or product authored by you) into which the Content Files, or derivations thereof, are embedded for your use ("End Use"). You may modify the Content Files prior to embedding them in the End Use. You may reproduce and distribute Content Files only in connection with your End Use, however, under no circumstances can you distribute the Content Files on a stand-alone basis, outside of the End Use.

And there is no documentation, nor any specific licence limitation relating to their use, save what's on the download page.
