Add-Ons: Audio Signals & Star maps?

Hello!

Some years ago (before Seti@home worked with Boinc) I had 1 or 2 programs (for Win XP) that showed the source of the signal on a skymap and, I think so, also gave the opportunity, to transform the signal to an audiofile.
As I'm running now on Mac, I'm searching for anything comparable to this. Does anyone have an idea? I haven't found that in the Add-On List here.

Greets!
