I recommend recording only raw data. I also recommend downloading the
latest software. Larry has not as yet posted the the links for WinQuake on
his Web site. If you enable the period-extending filter, please also check
the "Backward High-Pass Filter" box. I now use the new 32-bit version of
WinQuake for filtering instead of my WQFilter application.

Last year I incorporated Bob McClure's inverse filter into WinQuake and
WinSDR. See
http://sites.google.com/site/bobmcclure90/inversefilter for more
information on Bob's
filter. You can try the filter in WinQuake if you install this beta release:
*32-Bit: http://www.seismicnet.com/software/wq323b_32bit.exe*
*64-Bit: http://www.seismicnet.com/software/wq323b_64bit.exe*
And if you have a PSN ADC board you can use the filter in real-time by
using the
current WinSDR beta release available here:
http://www.seismicnet.com/winsdr/winsdr4x.html.
Please Note! In WinQuake the pendulum frequency is entered in seconds so a
4.5 Hz
geophone would be entered as 0.222. In WinSDR the frequency is entered in
Hertz, so a
20 second Lehman would be entered as .05. I should normalize this, I'm just
not sure
if I should change WinQuake or WinSDR...
