Ah, no!
So, what you're seeing is no processing delay caused by our
implementation of the xlating FIR filter, but simply *group delay*,
which every linear system has.
I don't know your background, so it's a bit hard to recommend some
literature, but group delay would be covered in a "signals and
Yes Marcus, I'm interested in the "excess" delay, thats why I need to cancel
the group delay.
Guess I've found the answer:
(len(filter_taps) - 1) / 2
Will try it..

Hi Angilberto,
am I right to assume that you already are considering the group delay
of the filter that you specified and there's "excess" delay beyond
that?
Best regards,
