I've checked 2KHz sine, which gives a traffic of 619, 3KHz with 659, though the game seems to be losing it, showing different traffic every time and some random numbers for higher values. Seems that the audio analysis engine is banging against the wall on these ones. You can try them themsleves, I used Audacity to create the tones. But keep your speakers down and your headphones off if you don't wanna see blood coming out of your ears

BTW, 2KHz had a corkscrew at the beginning, reallt bugs me how they're created, if there's no fluctuation in sound
