Re: [PD] 2 pole lpf with resonance? Eample
cool nice one. if you add this to your resonance slider, it will be even smoother: [resonance slider] | [$1 50( | [line] ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

Good idea! Thanks! I stuck it in on my own version. :) hard off wrote: cool nice one. if you add this to your resonance slider, it will be even smoother: [resonance slider] | [$1 50( | [line] ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] 2 pole lpf with resonance?
Hallo, Vreahli the Audio Bandit hat gesagt: // Vreahli the Audio Bandit wrote: Hiya. Okay - so here's the skinny. I set out about a half hour ago to figure out how to set up a 2 pole low pass filter with resonance in Puredata. Looks like that's apparently set up with a biquad~ filter. I read through the rather handy looking information over here at http://www.musicdsp.org/files/Audio-EQ-Cookbook.txt. I came out of that a bit more confused than when I went in. I also bumped in to http://www.creativesynth.com/MAXMSP/001-SynthBuildingMSP/sbm_03.html - which left me drooling quite a bit more than when I went in. Is there any way to set up a LPF with a live-tweakable audio rate resonance and frequency setting while avoiding doing the biquad math by hand? I can't even figure out how to get my computer to crunch those numbers for me. Thanks in advance for helping me out with this seemingly simple yet convoluted question. The biquad~ math isn't extremely hard, but of course it's still hard if you have no experience/knowledge about filter theory yet. Actually there was a long discussion about biquad two or three weeks ago, you may want to check the archive. The quickest route to getting useful biquad~ coefficients without going through the math would be the filter objects in the ggee-library (CVS at /externals/ggee/filters). They implement the equations from the Audio-cookbook. However [biquad~] doesn't have audio inputs to set the coeffs. Alternatively you could use the elementary filters [rpole~], [rzero~] etc. They accept signals for their parameters. Maybe I should sit down and build a 2plp now ...

Re: [PD] 2 pole lpf with resonance?
There are loads of filter externals for pd, how about moog~? Although it should be 4 pole but it does what the name suggests, its my favorite.
