Agc - Automatic gain control
Agc window=200 detect=0 dwind=10 thresh=25. < in.H > out.H
[200] length of the window in number of samples

[25.] threshhold
standard seplib parameters
Gain program with first arrival detection
Agc gains seismic traces by normalizing each sample by the
power of a window of samples surrounding that point.
When the detect= is set to 1, agc is not applied on a trace
until a first arrival is detected. The first arrival is
detected when a moving dwind exceeds an initial dwind by a
threshhold factor.
