I put in some debugging code near the filter tap calculations to see the
resulting filters. Would be nice to display the real filter curve in the
spectrum, with some infos like the cutoff frequencies, transistion width
and number of taps (complexity),  maybe next week I can play on that.

Printing out the taps, pasting into an octave instance, fft and plotting
was straigth forward. I love it when a plan comes together!
