So I've been looking for a certain effect to add to videos for my channel, and in doing so I can safely say that the internet is filled with useless and endless templates for simple audio visualizations or ungodly expensive suites that can't do what I actually want to do. (or at least similar)
There are three videos below, I believe them to have been rendered in After Effects.
this one is why I know it to be After Effects,
The uploader says to have been using javascript math expressions, alas I can not find anything where I could learn how to do anything close to that. Particles or no particles. I'm more looking at trying to find something I can learn from rather than "can someone do this." If there is any free resources out there I could possibly use?
The channel I linked has long been abandoned.
Edit: I can't even add the tags to this post of "Particles" or "Visualizer"
