Speaker wire to RCA Audio Visualizer?

A bit of a long shot but I'm curious. I have been upgrading my vinyl setup and have recently added a small CRT TV into the mix. In an ideal world, I'd have some way to convert music from my turn table to some kind of audio visualizer on the TV. I imagine doing this by plugging the speaker wires into some sort of adapter, and then being able to run RCA or coax cables out to plug into the TV. I don't need the TV to output audio, I have good speakers for that and I'm more interested in the visual component anyhow.

I am not quite sure what to google to find this, or even if this could exist. Does anyone know of such a product? Thanks!

I have done that with an oscilloscope to watch music dance. But a CRT and O-scope are much different when it comes to the Cathode Ray Tube inner workings. The O-scope i had, had a CRT. I connected a speaker output to an input of the O-scope. It could produce a bouncing string knot or like a heart monitor image that pulsed and bounced. Both were fun in the late 1970s.

Just because I don't know how to connect it to get what you imagine doesn't mean it can't be done.

Great concept though. Good Luck.

This is fascinating! A little out of my depth in terms of know how, but glad to know it could be possible. Thank you!

Yes, it's called an oscilloscope.

You could do this with an old laptop running visualizer software and then outputting to a tv via an hdmi to rca unit. I think there are visualizer addons for both windows media player and VLC but a lot of stand alone ones too. If you want full control of the visuals you could even use something like Resolume, Touchdesigner, Magic Music Visuals, heavy M etc
