sfmutter (4.0)
index
system/generic/Mmutter.c
Muting.

 
Synopsis
        sfmutter < in.rsf > out.rsf offset=offset.rsf half=y nan=n tp=0.150 t0=0. v0=1.45 slope0=1./v0 slopep=slope0 x0=0. abs=y inner=n hyper=n

Data is smoothly weighted inside the mute zone.
The weight is zero for t < (x-x0) * slope0
The weight is one for t > tp + (x-x0) * slopep

The signs are reversed for inner=y.

Parameters
       
 
bool abs=y [y/n]
if y, use absolute value |x-x0|
 
bool half=y [y/n]
if y, the second axis is half-offset instead of full offset
 
bool hyper=n [y/n]
if y, do hyperbolic mute
 
bool inner=n [y/n]
if y, do inner muter
 
bool nan=n [y/n]
if y, put nans instead of zeros
