**DOES NOT WORK IN THE BROWSER** I made a sound graph that is accurate, unlike the project that came with scratch. This one is much more like a professional program. I programmed it in a way to make it run fast (by breaking up the script). Feel free to do whatever you want with it. Also, it should work better if downloaded. Switch to presentation mode to make it run faster. Also, you need a working microphone that sends its output to your speakers for this to work. If you play other sounds through your speakers, you will affect the graph as well.
