If you have drawn very detailed filter curves, it is imperative that you save the curve
parameters. When switching modes or parameters, the curves will appear to be closely
matched but will not maintain the same details.
Make sure that when previewing in real-time at a high rate that the value of the program
buffer in the "Options menu> Program Preferences -> Advanced Buffer Settings (view
page 701)") is at least just as high, or even better, a bit higher than the set rate. If this isn't
the case, real-time previews won't be possible. Rates higher than 8192 are hardly sensible
when previewing in real-time as the internal real-time buffer size of the algorithm
corresponds to the set rate. In this case, editing while previewing in real-time is awkward.
Save/Load: Here you can save or load all parameters and curves. The default file
extension is *.FFF.
Important: If you want to apply the filter to other samples, the "Draw" mode parameter
has to be set to "Filter". Only then will the red curve be saved. This also applies if the filter is
indirectly applied by editing the blue curve in "Direct draw" mode.
However, if you save when "Direct" is selected, the saved frequency range can be
applied to other samples. In this case the saved blue curve is transformed into the red
one when loading.
FFT Filter – Problems & solutions
Modulation effects when using extreme filter settings for low frequency ranges
Set the "Precision" setting in the "Expert" dialog from "Low" to "Normal" or "High".
Problems with the real-time preview when using higher rates:
Make sure that when previewing in real-time at a high rate that the value of the program
buffer in the "Options menu> Program Preferences -> Advanced Buffer Settings (view
page 701)") is at least just as big, or even better, a bit bigger than the set rate.
It is not possible to completely fade out individual parts of the spectrum.
Select "Filter" in draw mode and reduce the "Min. range" value in the "Expert" dialog to ca.
-100 / -120 dB.
You have corrected the frequency response of a sample and analyze the result
again. The result does not match the corrected frequency response (the blue
curve before starting the filtering process).
If you use the "Analyze all" function and set the filter parameter to "Precision: High" in the
"Expert" dialog when analyzing before and after filtering, an approximate match will be set.
Resonance-like sounds occur even with broadband band passes.
Reduce the slew rate of the band passes by avoiding creating vertical lines when drawing.
In the "Fade start" or "Fade end" filter mode, fading does not happen uniformly.
In this case you should select the highest setting for the filter parameter precision in the
"Expert" dialog. In "Direct" fade mode, the problem is reduced when the rate is reduced.
