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 channel I linked has long been abandoned.
Edit: I can't even add the tags to this post of "Particles" or "Visualizer"
