I don't see much scientific value in non-seismic or non-geologic signals. I=
 prefer to remove structure or man made noise, for example, from my recordi=
ngs. As I see it , the sensor response is also not necessarily what the ear=
th is doing at ones location. The scientific value that I see is how to rem=
ove the transients without editing the signal.=20

I would think if you are serious as scientist
you keep the raw file
as it originally was even with the flaws.
Any modification to the data renders it
useless of most scientific value by
creating a subjective work of art.

But the tool might be useful such as before doing an fft
by getting rid of cal marks or such.
