Re: [PD] iemlib low pass filters exhibiting jitter?
cyrille henry c...@chnry.net: the biquad object from nusmuk audio (bq~) does also have audio inlet for filter coef. since it's a biquad, you can shape your filter... thanks everyone for suggestions and comments. in the meanwhile i disovered biquad object, which was perfect for my needs. i will also try high (150ms) interpolation time and [block~ 1]. and, ah, yes, moog filter... best, luka -- sujet est machinique!

[PD] iemlib low pass filters exhibiting jitter?
hi, just a quick question, is it normal or somewhat on purpose that all versions of low pass filters in iemlib (from lp2 - lp10 and cheb, butt, bess and crit) exhibit slight high pitched jitter when cutoff frequency is being dynamicly changed? is it a nature of such filter or just a type of implementation that somewhat doesn't take care of interpolation (if interpolation is a problem at all)? any thoughts welcome... is there a way i could avoid that jitter with these filters? is there some other high-pole low pass filter in some other library i could use? sure, i can always use series of [lop~] .. best, luka -- sujet est machinique!

Re: [PD] import-disabled list-abs
Hans-Christoph Steiner h...@at.or.at: [import] is definitely not deprecated. I've never seen 'import- disabled' before, that's very strange. in sfruit/cpugraph patch there's an object [import-disabled maxlib] which is not created (dashed borders). maybe that gives a clue? in fact, doing a grep on patches reveals sfruit lib seems to be the culprit: random@wonko:/usr/lib/pd-extended/extra$ grep -R import-disabled * controctopus/note-learner.pd:#X obj 736 16 import-disabled nsend list-abs; sfruit/menubar.pd:#X obj 51 204 import-disabled zexy ggee; sfruit/list-dripx.pd:#X obj 238 123 import-disabled list-abs; sfruit/mate.pd:#X obj 62 50 import-disabled moonlib ggee; sfruit/symbol-s2l.pd:#X obj 119 128 import-disabled zexy; sfruit/trimdirs.pd:#X obj 303 253 import-disabled zexy list-abs; sfruit/list-value-help.pd:#X obj 439 23 import-disabled list-abs; sfruit/troute.pd:#X obj 378 17 import-disabled iemlib list-abs; sfruit/list-value-extend.pd:#X obj 281 42 import-disabled list-abs; sfruit/color.random-dark-light18.pd:#X obj 261 25 import-disabled list-abs; sfruit/eqpowmix~.pd:#X obj 66 113 import-disabled hcs; sfruit/list-idx-list.pd:#X obj 135 68 import-disabled list-abs iemlib; sfruit/color.random-dark-light24.pd:#X obj 192 21 import-disabled list-abs; sfruit/list-decorate.pd:#X obj 167 92 import-disabled list-abs; sfruit/list-slice.pd:#X obj 308 24 import-disabled list-abs; sfruit/list-range.pd:#X obj 152 246 import-disabled list-abs; sfruit/hotpack.pd:#X obj -95 18 import-disabled iemlib; sfruit/saveclear.pd:#X obj 111 22 import-disabled toxy; sfruit/dialog.under-cursor.pd:#X obj 351 21 import-disabled hcs; sfruit/list-value-extend-help.pd:#X obj 451 20 import-disabled list-abs; sfruit/color.hsl2rgb.pd:#X obj 372 52 import-disabled list-abs; sfruit/cpugraph.pd:#X obj 436 72 import-disabled maxlib; sfruit/list-split-at-help.pd:#X obj 256 36 import-disabled list-abs; sfruit/list-sample.pd:#X obj 241 65 import-disabled list-abs zexy; sfruit/storebang.pd:#X obj 329 170 import-disabled zexy; sfruit/symbol-shorten.pd:#X obj 187 37 import-disabled list-abs; sfruit/dotrouteOSC.pd:#X obj 193 35 import-disabled zexy; sfruit/gop-edit.pd:#X obj 325 55 import-disabled iemguts; sfruit/vmetro.pd:#X obj 375 29 import-disabled list-abs; sfruit/list-split-at.pd:#X obj 85 14 import-disabled list-abs; sfruit/list-idx-many.pd:#X obj 285 34 import-disabled iemlib list-abs; sfruit/pcount.pd:#X obj 174 191 import-disabled iemlib; sfruit/savebang.pd:#X obj 124 17 import-disabled toxy; sfruit/screendimens.pd:#X obj 139 35 import-disabled toxy; sfruit/dialog.yes-no.pd:#X obj 481 22 import-disabled list-abs; sfruit/deeprouteOSC.pd:#X obj 553 20 import-disabled zexy list-abs mrpeach; sfruit/countseq.pd:#X obj 180 9 import-disabled list-abs iemlib; sfruit/list-decorate-help.pd:#X obj 416 30 import-disabled list-abs; sfruit/beat2frac.pd:#X obj 178 46 import-disabled zexy list-abs; sfruit/list-swap.pd:#X obj 243 67 import-disabled list-abs; sfruit/pausetimer.pd:#X obj 199 57 import-disabled iemlib; l. .hc On Dec 3, 2010, at 9:18 AM, Luka Princic // Nova deViator wrote: hi, i'm working on an abstraction that contains an object from a library for which i need to create [import nusmuk] in order to use ([granulator]). when i create a new instance of that abstraction, pd console reports import-disabled list-abs ... couldn't create could someone explain what this error means? is it deprecated to use [import] and i should rather use syntax like [nusmuk/granulator] ? l. -- sujet est machinique!

[PD] [GEM] pix_film mjpeg crash
