Hallo!
hopefully some people will give you some good advice, because i would also like to see a good EQ for pd...
...
[fir~] is EXACTLY what I wished :)
hm - I don't this that an [fir~] is that good if you want to design EQs ... The standard EQs are normally designed with shelving and peak/notch filters (wich are a combination of allpass, so IIR filters ...) There are a lot of filters in the iemlib (e.g. hml_shelf~, ...) and I think Miller also described some filter-design methods in his book ...
