Simple sound to light is quite effective. Bear in mind a lot of the cheap of the shelf options are noisy.

The lighting environments you mention are practised in advanced, cue sheeted, programmed into a lighting board, and timed with a human typically in the loop to handle deviations that may arise.
Most disco / club lighting is "set a pattern for a BPM and let it go" regardless of the track. Except really high end clubs which do the lighting board + humans thing.
What you're likely to achieve is either:
- Audio input into a visualizer that controls lights — it will be subtly laggy, but you will notice and dislike it.
- Detect BPM and set a pattern that beat matches — this is the small club / disco scenario, and honestly it's about as good as you're going to get.
Bear in mind that lag isn't just detection of the music, but it's having lights that can go from off to on fast enough, and change colour fast enough.
Personally, if I wanted to do this I'd ignore the idea of lighting and instead go straight to a Smart TV and see if there's an app that will full screen a WinAmp style visualization, and then split the output from the amp to the TV somehow and let it do it's magic.

Anyone in this thread dabbled with triggered lighting in addition to their hi-fi set up? Either at home or I guess in studio/theatre/gigging environments
