Have you ever been to a sporting event and seen a “noise meter” appear on the big screen? Even though it is rarely ever an actual functioning noise meter, it always gets the crowd riled up. So let’s take it to the next level and really give them an animation to cheer for!

---

In this first part of this tutorial, we will create the noise meter, the housing, and create a realistic LED visualizer animation from scratch.

There are some tutorials out there that show you how to animate EQ bands. But most of them are far too complex and do not achieve a very desirable look. I will show you a simple way to create this animation without using any audio files to drive the animation, and without using overly-complicated expressions.
Let the destruction begin!”
