Hi, just want to mention two typos:
rzero~-help.pd mentions that this was a "recursive" filter. Maybe this is a copy+paste error from rpole~-help? The difference equation in biquad~-help.pd gives an x[n-3] instead of x[n-2] cheersz, P _______________________________________________ Pd-list@lists.iem.at mailing list UNSUBSCRIBE and account-management -> https://lists.puredata.info/listinfo/pd-list
