the difference between the two is next to nothing, mostly a DC
offset. i'll use yours for the next FTs. is that 'Harris' as in
'S.W.Harris'? ;)
Well, I think its best to develop with maximum wuality,
then when its
working, work out how much we can reduce the CPU cost and still have it
sound good.
agree. though it's always good to keep in mind what is costly
and what is quick when choosing an implementation approach.
good god. know
an alternative source for calculating the
coefficients? Bill?
I have some text books that will have it in, I can compare that to NR.
after some NR 5-10 reading, it looks to me like harmonic_gen is
missing the work pcshft() from the book text is performing, yet
its output seems well-scaled.
it just occurred to me that it may be feasible to skip the
coefficient calculation in realtime by simply storing these
instead of harmonic amplitude tables. makes lerping difficult
though.
