Do any of you know if they're Butterworth or what?
I'm not sure how much difference it makes for low-order filters (biquad has 2 poles and 2 zeros). The differences really matter more for higher order filters, say 8 poles or more...
You could waste time calculating coefficients for a biquad cascade (the process is quite involved - see the mkfilter package online), but I'd just use the ones already made in iemlib...
