Hey people, While I'm not an expert with digital filters, I did manage to piece together a decent-sounding ladder emulation instead of vcf~ a while ago. It only does resonant lowpass though. It's called mvcf~ and is found in the ekext externals library. I've since been reading about analogue

I'm pretty confident [hip~] would not loose its efficiency when using iemlib's recipe. Both hi pass filters have a feed forward and feedback component, with coefficients for normalization and feedback. Calculation of these coefficients is a bit more involved with iemlib's recipe, using trig

2016-10-14 Thread Christof Ressi
There are a number of big problems with all build-in filters in Pd (expect for the raw filters). Problem number 1: [lop~] and [hip~] both use a weird (you could also say: wrong) formula for the cutoff frequency which makes them gradually converge to a fixed output state (reached by about 7000
