hello everyone,

I watched a great Unreal twitch about FX and there was mentioned tutorials about how make dynamic noises here Particles with Bill Kladis | Feature Highlight | Unreal Engine - YouTube
anybody knows where i can read about it? 2 months later and nobody asked for my comment on youtube, so decided to ask here.

thanks for the help!
