Best LED setup for audio visualization : led

I would like to set up LEDs to that are responsive to the external speakers of my record player, that I plan on attaching around my room. I’m quite out of touch when it comes to LEDs, the options on amazon often seem too good to be true and possibly dodgy. I’d like a simple quality setup, that the lights can easily be modified and are fluid. I don’t have a desktop nor laptop readily available and my speakers don’t have outputs. I’d appreciate some sort of direction or advice, I think this could be a great way to venture into LEDs.
