Sound waves

Hello, so On the Boris FX Sapphire page, and in their promo video, it shows a beat box with sound waves coming out. I see other AE effects tutorials for stuff like this, but not exactly like how it is shown in the Sapphire video.

But there is no where explaining which effects to use and how, since it looks like there is multiple being used. I went through all of them and can’t even comprehend which would be used and how.

How do we create sound wave effects like that? Are they being linked to moving shapes? (the more dense rings that keep coming out of the speakers at set interval)

Do you mean these?:

Omg, this is exactly what I was looking for. Thank you! Why I couldn’t find these, I’m not sure. I need to re-search the learning page again I guess. Thanks for posting these.
