I'm sitting outside on my deck. Birds are chirping, dogs are barking. There was a clear 20kHz band, but the resizing rectangle was just randomly jumping around, and when I turned on the hands free scrolling the webpage started jumping up and down randomly and rapidly. But hey, this is an excellent project! Love it.
