I had also noticed that the CSD had, for no particular reason, ksmps=1,
so if you did not change that, I expect it would have been slow. The
results I mentioned before were for ksmps=64.

yes, the DC blocking has its issues, but that is the same with any other
method that tries to turn a pulse into a saw or square. A few tweaks and
it could be OK. I also had another method of removing the mean without
actually using a DC blocker: find out the mean for a range of frequencies,
store that on a table and just subtract that from the signal. That probably
might turn out to be better.
