reacTIVision client in PD on Ubuntu 64 bit
by Menno van der Woude 05 Nov '10

05 Nov '10

Hello, not sure if this should go to this list or to the "dev" list... Running Ubuntu studio 10.04 64 bit, I have a problem with the reacTIVision client in Pure Data (extended, 0.42.5-2). Trying to put the client on the canvas, gives the message: "/home/menno/pd/TuioClient.pd_linux: /home/menno/pd/TuioClient.pd_linux: wrong ELF class: ELFCLASS32" Seems like it was built solely for 32 bit systems? I really do not know how to resolve this, or how to build a working pd-client from the source. Attached is my attempt to build an alternative client, using mrpeach [udpreceive] and [unpackOSC]. This works, however the problem is with 'addObject' and 'removeObject' messages that the regular client gives. In what I built now, this only works if there is only 1 fudicial in sight. Updates keep on going so work fine with multiple fudicials in sight of the camera. In example 2, I have tried resolving this by creating an [inlet] to determine which fudicial number this client is for. However, using multiple clients is of no use, because the [updreceive] object can only be used once, multiple copied will not output data. Any ideas either on how to resolve the initial issue, or how to improve this alternative idea for a reacTIVision client? Ciao, Menno.

Boomerang for Pd
by Dan Wilcox 05 Nov '10

05 Nov '10

Howdy all, A friend and I made a small patch for class demonstration to replicate the delay line used for Richard Serra and Nancy Holt's 1974 "Boomerang". The speed of the delay is such that the returning voice confuses the brain of the speaker causing slower speech and comprehension. It is a very simple, but elegant idea and everyone enjoyed trying it. http://danomatika.com/blog/boomerang-for-pd/ -------- Dan Wilcox danomatika.com robotcowboy.com

Phase and impulse response measurement
by Christoph Kuhr 05 Nov '10

Hi everyone, i wondered if someone made a patch measuring the PHASE of a reference signal compared to measured signal and also if someone made a patch measuring the IMPULSE RESPONSE of a reference signal compared to measured signal greetz Ck

Shifter~ Object for Linux?
by Pierre Massat 04 Nov '10

04 Nov '10

Hi all, A few months ago I posted a message about a pitch shifter and someone pointed me to the shifter~ object ported to Pd by Julian Villeguas ( http://julovi.net/j/?page_id=7). Unfortunately the makefile wasn't written for Linux. Is there a way i can compile it to run in Fedora? Thanks! Pierre

Purpose of sig~
by Jamie Bullock 04 Nov '10

04 Nov '10

Hi all, This is more of philosophical question than anything else. I'm curious to know why [sig~] hasn't been designed out of Pd. Why not have implicit control -> signal conversion everywhere it is possible? For example why not allow this? |2( |3( | | [+~ ] Jamie -- http://www.jamiebullock.com

Fedora build of Pd-extended 0.42.5?
by Pierre Massat 04 Nov '10

04 Nov '10

Hi, I 've read on Hans' website that Planet CCRMA needs a build of the latest Pd-extended. I have Fedora 12 on my laptop and I'm beginning to realize that it'd be actually cool to have an updated version of Pd to play with. I'd be glad to help, if : 1- this isn't too complicated, because my knowledge is extremely limited (I've read the page on Pd.info about building pd, if it's only a matter of downloading all the devel tools and typing Make in a terminal it's cool) 2- this won't take too long (cause i have quite a lot of work to do right now).

Re: [PD] Listen: High-Spheres, Participatory Soundscape Concert Re-new 2010

Hi Knud! thanks for your feedback, that concert has been an inspiring experience indeed. Personally speaking, it was very interesting to see how participants related to each other's sounds. There was who wanted to be the loudest, who kept following the "orchestra", but almost everyone after a while started to think about how to produce interesting sounds and exploit the interactive system in the best way. And that was one of my greatest satisfaction. Kids were going crazy... :) In the last part of the session there were only 3/4 kids building a huge wall of sound with their screams. Some kids were even running away from their parents to come play with the system, specially when they saw nobody was using it.

manipulation of symbols?
by João Pais 03 Nov '10

03 Nov '10

Hi, is there any object that allows a more extended manipulation of symbols? For example, I have symbols with the format 1234-56-78_12-23.aaa, and I wanted to get only the floats inside, and use them on mathematics. For now, the only way I see to do that is to use several [splitfilename -], until all the individual elements are separated. Or is it possible to do that with sprintf?

(sorry for x-posting) Dear all, I just uploaded an excerpt from 6 channels open air participatory soundscape concert "High Spheres" hosted at Re-new Festival, Copenhagen in May 2010. The concert - performed by the audience and managed by an autonomous responsive system developed in Pd - took place for the opening of the festival and last around 40mins, with a late night reprise. As always, feedbacks, critics, suggestions are very welcome, thanks, cheers, Listen on Soundcloud: http://soundcloud.com/marcodonnarumma/marco-donnarumma-high-spheres-partici… Further info about the project: http://marcodonnarumma.com/works/high-spheres/ A report of the whole festival: http://www.thesaddj.com/re-new-digital-art-festival-report/ -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher Ongoing MSc by Research, University of Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net _______________________________________________ Pd-announce mailing list Pd-announce(a)iem.at http://lists.puredata.info/listinfo/pd-announce

Re: [PD] Non-Linear Quantization / Bitcrush
by Ludwig Maes 03 Nov '10

03 Nov '10

So you want amplitude 'a' dependant quantization size 'q' ? take your chosen q(a); in your example it seems you want a simple line: q=q(0)-k*a; define f(a) as integral of 1/q from a=0 to a; also calculate the inverse of f(a) i.e. a(f); now for each sample do: out=a(round(f(in))) where round is any floor or the like... have fun! ps: in your example: q=q0-k*a with for example q(0)=0.001 and q(0.8)=0.0001: q:=0.001-0.0009/0.8*a then f=2558.427881-1111.111111*ln(10.-9.*a) and inverse=easy On 2 November 2010 19:20, Ludwig Maes <ludwig.maes(a)gmail.com> wrote: > This is pretty easy actually, I use such things mostly to guide my > rhythmical quantization... > > On 2 November 2010 19:19, brandon zeeb <zeeb.brandon(a)gmail.com> wrote: >> This is even better.
