Samuel,
Sorry, but nothing is clear to me about your statements:
1) what shows you that iir() is correct while the analpf + horner way
is not?
There are several reasons:
a) The result of using iir() is consistent with the expected frequency

Dear All,
I have problems with this script:
Fs = 44100;
fo = 500;
B = 2^(1/6)-2^(-1/6);
// Low-pass Butterworth
hLPs = analpf(3,"butt",[],1);
// Band-pass Butterworth centered at fo
hBPs = horner(hLPs, (2*%pi*fo/%s
