I'd actually argue it has some wicked problem characteristics. The input space is enormous (all possible audio), perception is subjective and nonlinear, and there's no objective function to optimize against, only "does this feel right?". Every solution you try reframes what "good" means. It's not as hard as social planning but is way harder than it sounds, no pun intended.

Ever seen https://www.youtube.com/watch?v=oNyXYPhnUIs ? There are a lot of things people might think feels right.

isn't it the exact same problem than "making a good movie" or "making a good book" ? this is just thoroughly subjective.

When the author says:

> Every commercial audio reactive LED strip I've seen does this badly. They use simple volume detection or naive FFTs and call it a day. They don't model human perception on either side, which is why they all look the same.

well no, if they sell, then they are doing just fine until someone comes up with the $next $thing

fta: The biggest unsolved problem is making it work well on all kinds of music.

The wickedness comes from wanting something that works just as well for John Summit as the Grateful Dead as Mozart and Bad Bunny.

But it seems like you could cheat for installations where the type of music is known and go from there. The other cheat is to have a "tap" button, and to pull that data and go from there.

mental note: the thought "it can't be that hard" when obviously it is sent me down a rabbit hole for a couple of hours
