PD on Android - how far is it and how far can it go...
by Luigi Rensinghoff 09 Jul '10

09 Jul '10

Hi List. i have some question about PD on Android. Honestly, i dont know much about Android, so please be patient.... I would like to know how far the development is, the last info i read said, that sound is not working.. Any idea how long it will take ? The other question is, if it is possible to use pd on android in the background, so that another app is sending some data (would be: Compass data and direction) to PD and let PD process the sound... Would it further be possible to have some HRTF functionality with that , or are there librarier involved that cannot be ported to android ? Any other suggestion how that could be realised in android ? Have a good time...and thank you for your help Luigi

pd on armv7 (beagleboard): crackles / pcm not available?
by Damian Stewart 09 Jul '10

09 Jul '10

hi all, i'm trying to get Pd to run on my BeagleBoard, and running into a couple of problems. any help greatly appreciated. this is for an installation of this work: http://ll.frey.co.nz which is due to go live in August at Kapelica Gallery in Ljubljana, Slovenia. basically, the problem is that instead of sound output i'm getting these crackles: http://soundcloud.com/damian/pure-data-on-beagleboard-sound-issue 1. i tried Hans' Reware image ("BeagleBoard Pd, Python, Lua image" from here http://dev.eyebeam.org/projects/reware/wiki/Releases ). i'm not sure what version of Pd this is, but it's using OSS as sound device. this makes nasty crackles, that are related to the volume of the sound output and also to the content of the sound i'm trying to output. the crackles don't go away if i increase the audio buffer to 500ms. they sound a bit like a pot full of popping popcorn : http://soundcloud.com/damian/pure-data-on-beagleboard-sound-issue 2a. (Ubuntu 10.04 installation) i tried apt-get install puredata (v. 0.42-5) on my Ubuntu install, which produces the same kind of audio crackles as the Reware image. 2b. (after sudo killall xdm) i tried running pd -nogui -alsa -noadc -open my_test_patch.pd, which gives me no sound output at all, just a message that "snd_pcm_open (output): Device or resource busy". i know Alsa is working on the Ubuntu install because i can use aplay and mpg123 and get perfect sound output. i don't seem to have OSS available on the Ubuntu image. i'm running a BeagleBoard C4, and i wonder if the Reware image was only tested on an earlier revision board. again -- any help greatly appreciated! thanks damian -- damian stewart . @damiannz . damian(a)frey.co.nz frey . contemporary art . http://www.frey.co.nz

Re: [PD] popen vs shell bug
by Hans-Christoph Steiner 08 Jul '10

I am thinking of the ideal version of this, an object that would give you an inlet for STDIN then two outlets for STDOUT and STDERR, plus a status outlet and an inlet to set what to run. It could be something like this: [process /usr/bin/python] Then you could send python bits to it via the first inlet, and receive the reply via the outlets. So something like a cleaner [shell]. .hc On Jul 1, 2010, at 2:25 PM, Kim Cascone wrote: > I like having the outlet on [shell] so I can pipe data to the console > > Hans-Christoph Steiner wrote: >> >>

flatspace "popup" doesn't work
by Raphaël ILIAS 08 Jul '10

08 Jul '10

hi list! Currently i'm using Pd-extended 0.41-4 on windows vista. [popup] from flatspace is no longer working : the object appears, but does not output anything when you select an option in the menu. Instead of that I get a message in the console : error: popup0x16d48f0: no such object I got no idea on what to do... I find [popup] is a very useful GUI to save room on a graph-on-parent abstraction. Any idea ? Thanks, phae

Re: [PD] GEM pix_film crashing on OSX 10.5
by Marco Donnarumma 08 Jul '10

[pix_film] is well known for this kind of crash-y issues. It might depends on the codec you use (i.e. different codecs are installed on MacMini) However, have you tried using [pix_movie] instead? In my experience it's more reliable.

A10Lab - Live Media and FLOSS Workshop - Book Now!
by Ryan Jordan 08 Jul '10

08 Jul '10

A10Lab presents: Live Media and FLOSS* Extended Production Seminary with Marco Donnarumma Monday 26th - Friday 30th July 17:30-22:30 daily @ C4CC, 16 Acton Street, London, WC1X 9NG £80 pp The workshop is limited to 20 participants. Please register by sending an email to info(a)a10lab.com or ryan-jordan(a)hotmail.co.uk with the subject heading “LiveMedia and FLOSS workshop”. Full information here http://www.crealab.info/digitalab/?p=393 *Free/Libre Open Source Software In-depth Theoretical and practical audiovisual live performance seminary using FLOSS. Pure Data audiovisual real-time processing, tricks and tips to create your own performance tool. Description The seminary consists of four parts. During the introduction the participants acquire a basic theoretical knowledge about Live Media. The introduction is extended through a review of selected audiovisual works in order to explore and analyse the potential of the audiovisual research. Therefore participants are introduced to the concept of FLOSS (Free/Libre Open Source Software), they familiarize with few FLOSS software as they understand its practical and theoretical keystones. In the second part participants learn the meaning of real-time audio-video data processing reviewing the most common production tools. Eventually they deal with the process of an audiovisual performance pre-production using FLOSS: from brainstorming and concept design, through planning of the audiovisual format, to the collection of support materials such as texts, tutorials, and the drawing of sketches representing the logic structure of data processing. The third part focus on Pure Data graphical programming environment. Participants learn to communicate with Pd and how to surf through the audio and visual processing libraries. They build basic processing structures and discover tricks and tips to create their own performance tool. For the last part the work group is split in smaller groups. Through practical individual exercises participants acquire the technical know-how about the creation/collection of moving images and sonic events within the Pure Data graphical programming environment, thus they develop an original software, following the standard realisation steps: beta-testing; analysis of errors and its correction; and final testing during a collective jam performance. Aim The seminary seeks to give the participants who don't have previous experience in programming and Live Media practice the needed theoretical and practical knowledge and skills to feel comfortable within the FLOSS creation environment. The classes' aim is to make the participants able to understand and assimilate the diverse passages of the creation process of software ad-hoc in order to be independent during the planning and development of a FLOSS project (musical, audiovisual, multi-media or theatre pieces) using the audiovisual language. Who's it for Musicians, producers, live visualists, film-makers, programmers, sound designers or passionates of digital arts or electronic music and experimentation who want to enhance and extend their skills and tools will find this seminary inspirational and fundamental for the further development of their works and creative ideas, free from the limitations of user-friendly and proprietary software. No previous programming experience is needed. What to bring Participants are invited to bring their laptops and encouraged to bring musical instruments, cameras, photo cameras, webcam, microphones, sensors, MIDI devices and fresh, unusual ideas!

Playing and recording simultaneously
by Henrique 08 Jul '10

08 Jul '10

Hello everyone, I have recently downloaded PD and I am using it to estimate the acoustic response of a room. To do this, I am following the procedure described at http://cnx.org/content/m15945/latest/. However, I have a question about how Pure Data works when I simultaneously play a waveform and record the output using a microfone (that is required for the estimate). Is the clock frequency of the D/A converter which produces the output syncrhonized with the clock frequency of the A/D converter wich produces the recorded signal? That is a very important question when trying to measure an acoustic response, and I couldn't find the answer at puredata.info website. Regards, -- Henrique Goulart University of São Paulo, Brasil
