The result looks good, but how correct is the double answer? - lets calculate the filter with quad precision i MATLAB. (34 digitits of precsision in Base 10).
My laptop does not have HW support for that :mrgreen: , so this will take some machine time in MATLAB to calculate the 10 s of audio data.
Special floating points formats ???

Double float didn't have much problem with that one.

Another useable filter is the subsonic filter - maybe you want to use it @ 192 kHz. No 'HIFI' problems here.
