$\begingroup$ Following yours & @Hilmar 's advice, but drawing a blank on the A weighting filter. I've got a 2-order IIR to fit in my micro (3 coeffs for forward &back), but I can't find coeffs anywhere, and don't use matlab. Any pointers? $\endgroup$

$\begingroup$ The wiki transfer function is 6th order. Found an interesting post showing three 2nd order IIRs. If I run them in cascade (which I guess is the intent?), the output looks vaguely useful, but I'm literally viewing it in a console using ascii printout - a bit limited. Here's the link jenshee.dk/signalprocessing/aweighting.pdf $\endgroup$
