Now 129 hz and 131 hz.
Now 129 hz and 129.1 hz. (Wait it out, notice the changes)
Singers can use sine waves to train pitch accuracy, as they sing one note against a sine wave and aim to minimize the warbling.
This project was made with the help of ChatGPT. It's impressive to see what it's capable of!
I did learn some things along the way as I tried to fix things
