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.
