NAME

vfftpass - elastic-symmetric low and high pass filter for VFFT  

SYNOPSIS


vfftpass       [-hi] [-base #] [-c] [-floor #] [-F #] [-G] [-L]
               [min #] [-neg] [-r #] [-v] [<] VFFT [> | -o] filtered-VFFT
 

DESCRIPTION

 

OPTIONS

-base #
base value in filter plane. [Default=0.0], max 2.0.
-c
convex curve. Default is concave curve.
-hi
highpass filter (also -neg). Default is lowpass filter.
-f #
elastic scale factor. See curve, use -g option.
-F #
number of Frames in sample. Default is 16.
-G
only generate a plot data file for filter curves.
-L
Linear filter.
-min #
lower threshold value. The default is 0.01.
-neg
negate filter. It generates 3 - 1D high pass filters, then conbines them to a 2D or 3D high-pass like filter. The -hi reverse entire low-pass filter to generate a high-pass filter.
-r #
radius factor. default is 1 (100%). Range 0.1 - 1.0
-v
verbose.
