Hi Alexandre,

Great that you're doing this! For extra inspiration you could have a look at PoZeTools (http://kmt.hku.nl/~pieter/SOFT/RESP/html/PoZeTools.html). It's great software by Pieter Suurmond. He's the one who taught me filter design and he probably has some info about Z-transform on his website as well.

Hi there. So, I've been studying a lot about filters, and I'm doing this clone of max's z-plane in Pd.

I hope anyone can help me guide where to find how to convert the values of the complex poles and zeros to biquad coefficients. I really needed that...

Sorry if I missed it in Miller's book or some other obvious reference, I'm just really a newbie in filter design.

Thanks
Alex
