How to drive material parameter from sound wave amplitude?

Hey all, as the title says I am trying to figure out how to do an easy sound driving material parameter in blueprints. I’m imagining there must be a way to “get amplitude” of all playing sounds but I can’t seem to find functions that will give me that result. Furthermore, I’d like to set it up so that any arbitrary sound wave track in sequencer can cause this blueprint to respond accordingly.

Here’s a video showing my requirements:

I don’t know a way to do that exactly but, to get you started “On Audio Single Envelope Value” is an event for audio components, it should get you the volume of one sound ( a music track etc) that can be converted to a material parameter.
