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

Audio installers sometimes have hardware devices called RTA's or Real Time Analyzers, which is a spectrum analyzer.
Detailed frequency analysis is done with an oscilloscope.
Pretty visuals via hardware is often done by DJ lighting and laser gear.
Everything else, you're talking a computer and software, as far as I know (as opposed to a dedicated box for the task, as you requested).

I tried to link a real hardware RTA, but I'm having trouble. Google tends to show only software versions. I thought I'd found one and then realized it was a spectrum analyzer for radio frequencies instead of sound waves. I'll keep poking at it.
The ones I've seen aren't small.

How small is small? Would a mini-ITX board + PSU in a box be small enough?

If you want a software solution, it wouldn't be too hard to setup a linux box with a sound card. Here are a couple I've found for a project I'm working on, I haven't gotten to the point of the visualization pieces yet, I've only slightly researched it. I'll be trying Synaesthesia first I think, as it's one of the only ones with half decent documentation. I have moodbar setup already, and I have a nice ruby script which will generate png images to the filesystem... if your interested let me know. SynaesthesiaFischeMoodbar

The one I've used (borrowed from my stereo shop) is the size of a small suitcase and weighs about 25 pounds.

Thank you all for your input.
I realize that this would be pretty easy to do with a computer and that may be the way to go. It would be cool, however, to have a small box that you could plug a TV or monitor into one side and and anolog audio signal in the other to get cool visuals.
Hmmm, If I were to design one, it would have to have decent graphics capabiliies, multiple output types, and possibly an interface with a computer to update/add visuals.
Kind of a cool concept. I will probably never get to it, though :P

Put a little mirror on its shades and then point Patrick's laser point of doom at it for the visuals
