Number of curves: Set the number of curves to be displayed here.
Filter transition
There are three
different modes available for dynamic filtering:
Direct: A simple fade is made directly between two curves.
Move/direct: In this case, both curves are faded, but the start curve is to the side, i.e. it is
moved onto the frequency axis. For example, if a band pass is set for the start curve, the
timing of the mid frequency changes (filter sweep). The corresponding high value of the
start and end curve specifies the extent of the curve move. If you are working in "Filter"
draw mode, edit the red curve first. If the entire filter curve is set to 0 dB, a higher value will
not be available.
Move: This method can be used to move the start filter curve. Once again, the
corresponding high value of the start and end curve specifies the extent of the curve move.
The second curve is used for specifying the "end point" of the move. Otherwise, it doesn't
have any influence on the result.
Resolution: This parameter affects the analysis and filtering processes equally. Set how
many individual analysis frequencies/filter bands should be available, in which case the
number of filter bands corresponds to exactly half of the value of the "resolution"
parameter. The higher the resolution, the longer the processing time needed – by approx.
5%/level.

Frequency analysis
A higher resolution is required for sufficient precision in the low-frequency ranges (from
8192). The precision of the analysis in Hz at a sample rate of 44.1 kHz can be found in the
table.

ere you only need high resolution (8192) for low frequencies or for specifically blocking
out overtones. For all uses the settings 1024 to 2048 will suffice. Values lower than 1024
are rarely needed.
