Seam carving audio
by Chris McCormick 08 Jul '08

08 Jul '08

Something struck me whilst out walking today; has anyone applied the seam carving technique: <http://en.wikipedia.org/wiki/Seam_carving> <www.youtube.com/watch?v=6NcIJXTlugc> to FFT data to do a timestretch/timecompress that is more sensitive to attack sounds and note lengths? Best, Chris. ------------------- http://mccormick.cx

Re: [PD] print all abstractions and externals
by Hans-Christoph Steiner 08 Jul '08

08 Jul '08

Hmm, sounds interesting. This would be useful for a better .app maker, where it only includes the files that are needed. (That would only apply on Mac OS X .app maker. The .deb maker I am working on will depend on the Pd-extended package) .hc On Jul 1, 2008, at 11:03 PM, Hans Roels wrote: > hello, > > I've made a patch that might be useful for others.

compiling external in Linux
by Jaime Oliver 08 Jul '08

08 Jul '08

Hello all, I am trying to compile a simple external (non-signal one) in Fedora in the following way: I put a folder with the .c file, m_pd.h and the makefile (attached) in the extra folder, then cd into that folder and then type make pd_linux and get the following error. I'd appreciate pointers to this. I just compiled this in OSX and it worked correctly (equivalent process and make pd_darwin) best, Jaime ERROR Message: [joliverl@maquina analista]$ make pd_linux cc -DPD -O2 -funroll-loops -fomit-frame-pointer -Wall -W -Wshadow -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -I../../src -o analista.o -c analista.c ld -export_dynamic -shared -o analista.pd_linux analista.o -lc -lm ld: analista.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC analista.o: could not read symbols: Bad value make: *** [analista.pd_linux] Error 1

Well, as always, the namespace thing is at the root of all this - if the namespace stuff was working (and it sounds like it's getting closer) then it would be perfectly fine to call it just [range] since it would require gridflow/range or import/declare gridflow to use. And, the second answer is other-language (e.g. Python) style reorganization of libraries to be author-agnostic - ordered by functionality. But, this requires a Organization Czar, it seems, and maybe no one is ready to be that person yet, so, until then, such helper-objects must stay in the homes of their authors for there's nowhere else to put them. (also, I think in this case, since grid-operators in GF have the #-prefix, those objects without the prefix are clearly distinguished as "generic helpers") Luke

XML-files
by j milo taylor 07 Jul '08

07 Jul '08

Hi, I also would like to find out how to do this. For me, i am developing a world in X3D. Sound is treated as a XML node, which has an associated transform in 3D space. So my question would be, how could i send something like this (audio stream?) to pd for processing? <AudioClip DEF="1500Audio" url="audio/Chesworth-2006-Proximities excerpt.wav" loop="true"/> Best Regards Milo

False flag of trojan in Pd
by Andy Farnell 06 Jul '08

06 Jul '08

I noticed this message on a public music related forum. "been thinking of trying pure data again as last time i downloaded it it infected my computer with a blade runner trojan so uninstalled it so yesterday started toying with the idea of trying it again as it seems pretty cool so i did and again it installed anouther trojan on my computer i downloaded from the pd wiki the windows version has anyone else had this problem or is it just me " AFAIK this problem has been known for some time. Does anybody know the particular virus checker that is falsely identifying Pd to be infected? Has anybody contacted the manufacturers of this software? a. -- Use the source

multislider again (was: data structure unclickable)
by Yvan Volochine 05 Jul '08

05 Jul '08

Hi. Here is (another) multislider made with data structures. It was tricky for me as I only learnt DS a few days ago... so there may be weird things in this patch. I was looking for a multislider that respond to clicks outside sliders and to horizontal dragging. I was obliged to use [ivnt] from iemgui in order to get mouse coordinates and move DS, but as DS always respond to mouse clicks, if one clicks near the "mouse area" of DS, horizontal dragging stops working and the expected list (id/value) does not come out... Hope it makes sense... Another thing, changing multislider size is done via scripting, and this outputs lots of errors in PD windows (due to scripting in structures (??)). It also crashes PD on my Mac (PD-vanilla 0.41.4) but kind of works on linux (PD-extended 0.40.3RC3). I also tried to name arrays with $0 in order to use multiple instances of this patch but I couldn't. This didn't work and I had many errors (especially with [element] object...). Here is the patch + help. If anyone is willing to have a look and give me advices, it would be much appreciated. Cheers. _Yvan

Hi list. Is there any way to make an array in a data structure *not* responding to clicks ? Cheers. _y
