This project was created for Day 15 of Getting Unstuck. While I was playing with an idea for a different sound-based project, I kept wondering what the "loudness" block was really capturing. I created a variable to display the loudness, so I could see its value. But the value was changing very quickly, and it was hard to get a sense of the individual numbers. So I created this project to visualize what was happening. I liked it enough that I set aside the other project idea and focused on this helpful tool instead.
