4. Graph window
The graph displays the changes in processed signal levels over time and moves at constant
speed from right to left.

Narrow scale
Displays the level of input signal.
A filled upscale signifies input

and he optimal level of input signal
can be set by using the

5. Acoustic signal spectrum window
It displays the spectrum of the filtered signal.
When working with EMD switching the window can have the following view :
Band pass of the filter on the figure - 0,21...0,95kHz. It is possible to switch over
to adjusting the image scale at vertical by means of ▲/▼ and volume in headphones
by◄/►. it is possible to switch over to adjusting the pass band and vise versa by means
dark segments
correspond to the
frequency components
of valid («continuous»)
signal
The frequencies at which light segments significantly predominate over dark probably are
the interference frequencies to be suppressed by the band pass filter.
