The scaling changes are in, as well as the warning and the corresponding
lines in
api_changes and CHANGELOG. I also added the converted matlab demo I
used to
figure this stuff out. Now would probably be the time to see if I did
something
wrong (especially the warning).

I suppose the issue is: what is correct? Or is it a matter of definition?
I don't have Stoica and Moses, but Bendat and Piersol eqn 11.102:
One_Sided_PSD = 2/(n_d * N * dt) * Sum(FFT^2)
where there are n_d is the number of averages and N

I found bug number 1859027 and have appended the below to the bug report.
When is the next release due and how likely is this to get fixed? I might have
time myself
to help in a week or so, but would appreciate some help if someone else has
time too (who
has looked at the source before...)

I cannot really compute the example without the pad_to support in svn.
Nevertheless, using something similar (nfft=128, noffset=64) gives similarly

Did you add 'pad_to'? If so, thanks!
Good to know. I recently (within the last month) did a bunch
