the threshold value with the maximum of 500ms delay. Then,
the system makes the following displays
: Makes displays in blue if the value is greater than the
threshold value.
: Makes displays in grey if the value is smaller than the
threshold value.
eThe input level of the microphone is sampled every 200ms
and the results are displayed on 8 levels. The display up-
