Step 2: Open the FFT Analysis Filter again. A blue curve depicting the current frequency
response of your sample/object is now visible. The red curve is the frequency
response filter. By default it is set to 0 dB for all frequencies.
Under given circumstances, according to the length of the selected range, only a portion of
the range is analyzed. To examine the entire range or object, click on the "Analyze all"
button to the top right of the dialog window.
Step 3: Now use the left mouse button to draw in the graphic display. The frequency
response of the filter changes according to the drawn curve. The blue curve also changes
while drawing: it now shows the frequency course almost reached by the sample after
application of the filter. The blue curve is therefore now referred to as the corrected
frequency response.
Note: If you use a faster PC, you can check the result in real time after pressing the
play/stop button. The changes may be heard immediately. Otherwise, you should use the
non real-time preview ("Preview" button).
2. Filtering in Direct Draw mode
You can also draw the desired frequency response (the blue curve) with your mouse.
Select "Direct" in "Draw" mode.
The yellow curve now displays the original frequency response as a comparison.
Changing the frequency response in this mode is rarely needed and can lead to over
modulation. For this reason, confirm that you want to "Prevent clipping" by clicking the
button of the same name after every adjustment to the frequency response.
By editing the blue curve you will of course indirectly change the frequency response of the
filter. To observe this, first reset the filter by pressing the "Reset" button. Switch back to the
other "Draw" mode "Filter". Now you will see that the filter curve is set back to zero. If
change back to "Direct draw" mode, edit the blue curve again and then switch once more
back to "Filter" mode; you can see that the frequency response of the filter will have
changed.
3. Dynamic Filter mode (fading between two filter curves).
Select the filter
mode "Fade start". The displayed frequency response in this mode
corresponds to the left border of the selected sample/object. You can also edit this
frequency response in the Filter or Direct mode, as explained in the previous two points.
However, filtering will now also directly affect the marked range of the sample or the
selected object in the VIP.
Switch to "Fade end" and edit the frequency response the same way. The displayed
frequency response in this mode now corresponds to the right border of the
sample/object. In this case filtering affects the end of the marked range of the sample or
the object selected in the VIP.
The red filter curve or blue curve with the corrected frequency response changes between
both range limits and is faded from the first to second curve. Thereby the first curves fades
into the second curve.
