[arm-allstar] simpleusb flash tone nominal level

BTW, forgot to mention that I'm blind, so I can't see any green bars. 
All I can do is read peak values through an external application that 
picks up from the same input as wires x.

This is why I'm looking for the actual amplitude value of that test tone.
