The equalizer process has two kinds of windows, called small and large. They differ in size and number of visible sliders.
Here you can see the small equalizer window having 16 visible sliders. The number of bands is 2048.
The equalizer window consists of a toolbar with control buttons, a graph area where the current signal spectrum ( yellow) and the filter are displayed, the scale/position controlling trackbar, the number of visible sliders ( 16/32) and the "elastic" controls at the bottom.
The toolbar.
The maximum resolution button. Changes the range of the X axis so, that part of the spectum is shown with maximum possible resolution. The maximum resolution is achieved in the situation when one visible slider corresponds to one equalizer band. The bands to sliders ratio is indicated to the left of the sliders area. In this picture it is equal to 128 ( 2048 / 16 = 128).
Multiplies the resolution twice. Changes the X axis range from [x1, x2] to [x1, (x1+x2)/2].
Decreases the resolution twice. Changes the X axis range from [x1, x2] to [x1, (2*x2 - x1) ].
Shows the whole X area , i.e. X axis range becomes [0, Freq/2], where Freq is sampling rate.
Initializes the filter, i.e. resets all sliders values to 0.
Y autoscaling. Sets the Y axis limits so, that the entire spectrum is shown ( regarding Y axis) .
Zoom in Rectangle. After pressing of this button ( its state changed to pressed) you position the mouse cursor within the graphs area at the left top point of the rectangle you want to "cut". Press the left mouse button and while holding it, move the mouse to the right/bottom point of the rectangle you want to "cut". While you hold the mouse button pressed, redrawing of the spectrum is paused and the dotted rectangle is indicated, corresponding to your mouse movement. Now release the mouse button and the picture will be redrawn with the axis ranges corresponding to the specified rectangle.
Y axis graduation toggle switch. Toggles between linear and dB switch. When pressed indicates dB scale.
Spectrum accumulation button. When pressed, spectrum accumulation takes place. While spectrum accumulation the average arithmetic spectrum is shown ( usually the current moment spectrum is shown). If you release the button, the accumulation is switched off.
Filter calculation. Calculates either inverse or harmonics stop filter(at your choice) from the shown spectrum ( current or accumulated, depending on the state of the previous button). If pressed, releases the spectrum accumulation button. ( i.e. resets spectrum accumulation). The filter is calculated in the range marked by the red triangles above the graphics display area. The rectangles can be moved by the mouse.
Filter sharpening. Makes the built inverse filter more contrast by making the negative filter peaks deeper and winder. Uses options set in the options window.
Automatic mode filtration. After this button is pressed the program performs average spectra accumulation for the specified period of time ( see Options window description) and then calculates the specified ( inverse or harmonics-stop) filter for the accumulated spectra.
Change size button. Toggles the window size between small and large window modes.
Indicator of equalizer output overflow. Indicates that output value is out of the range from -32767 to 32767. When overflow occures the button becomes active and the inner circle becomes red. Press it, and it will be disabled again till next overflow.
Scale and Position controls.
Additional scale and positions controls are the trackbar and two small buttons to the left of it.
These controls are used to indicate and to change the X axis limits. If we assume that the whole trackbar length corresponds to the whole frequency range ( i.e. [0, Freq/2], then the selected trackbar area ( i.e. blue) corresponds to the segment currently shown in the graph box. The trackbar in the picture below has the selected area equal to the trackbar length, so we can say that the whole spectrum is shown. You can change the limits of the selected area by clicking the left/right mouse button for the left/right edge .
The buttons to the left of the trackbar are used to move the X range left/right by the step equal to one visible slider band width.

The Sliders Area.
There are 16 visible sliders for small window mode and 32 for large. If we assume, that a 2048 band equalizer has a separate slider for each its band, then one visible slider corresponds to several "real" sliders. The number of such "real"sliders ( i.e. bands) per one visible slider is indicated to the left of the sliders area. It is 128 for the picture shown above. When you change the X axis limits , this value is also changed , reaching its minimum = 1 at the maximum resolution.
There is a **** field above each slider, indicating the average value of the "real" sliders, corresponding to it. The slider thumb position is also set to this value. That is the reason when you can see for example, the filter graph having a very low point ( -72dB) , while the slider corresponding to this filter position can show e.g. -16dB.( in this case -16dB is the average value).
If you move the slider the values of all bands coefficients corresponding to that slider will be set to the specified position.
“Elastic” mode controls.
There are two additional controls beneath the sliders area of the equalizer window. These are the controls for "elastic" mode.
They are the button and the white rectangle to the right of the button.
The button in the left bottom corner of the window toggles the "elastic" linearization On/Off. If there is a cross at the centre of it, ( as it is shown ) then linearization is "On".
The rectangle's selected area indicates the "elastic" limits. This area can be set by pressing the left/right mouse button at the point specifying the left/right edge. The selected area will become blue. To reset "elastic", put focus to the "elastic" rectangle control, and press "Esc" key on the keyboard.
When elastic mode is "Off " each slider is moved separately, i.e. when you drag any slider's thumb, only its position is changing.
The elastic mode is different. Suppose you have selected the elastic edges, corresponding to sliders "m" at the left and "n" at the right. That means, that if you drag the slider's "m" thumb now, all sliders thumbs between "m" and "n" will be moving ( except "n" itself) in such a way, that their positions will form a line from "n" to "m". The same will happen if you drag the slider's "n" thumb .
If you drag the slider's "k" thumb ( where m<k<n) , the positions of "m" and "n" will be fixed, and the positions of other sliders between m and n will form the line from "m" to "k" and further to "n".
When the linearization button is "Off", the filter values are calculated according to the positions of the "visible" sliders, i.e. by "steps", where each step length is equal to the number of bands per visible slider. When the linearization button is "On", each band coefficient is calculated separately, and the filter really looks like a line.
Equalizer Options.
To enter the equalizer options dialogue box , choose the options item from the system menu of the equalizer window. The options dialogue provides for changing of the equalizer bands number, filter contrasting options, spectra and filter drawing enabling and the value of accumulation time for automatic mode filtering.

The filter contrasting operation performs search for the narrow negative peaks of ideal filter characteristics and then it makes those peaks deeper and wider. This operation often gives some positive effect.
The filter contrasting options are:
· Discrimination level - the ratio of peak filter value and the “surface” value, used to consider this peak to be contrasted. The natural filter non-linearity stays unchanged if this value is about 0.5. If the value is 1 every local minimum will be contrasted. If the value is 0 , filter stays unchanged.
· Analysis window width ( Hz) - The width of peak that is considered to be narrow enough to be contrasted ( default 70Hz). If some useful information becomes lost , decrease the value.
· High Intensity ( YES/NO) - If specified ( yes), the peak is made not only deeper but wider too.
