Many were asking about the sound equalizer demo shown in the video below 
You can now download a sample project for UE4.26. Technically, the equalizer itself isn’t working properly, but it shows some of the Definitive Painter capabilities nicely. Please note that the project cannot be packaged because it relies on Sound Visualizations Plugin by Epic that’s intended solely for in-editor use.
Get it here and enjoy!
