I am looking around for a small device that takes an anolog audio signal and converts it to a video representatiojn of that signal in the form of say, a spectrum analyzer, fancy visuals like we have on the empeg, or Goom. I haven't seen anything like that anywhere, but it seems like it should exist.

Has anybody seen one of these? I don't even know what it would be called!

Thanks for any replies,

Brent
