"G05.execution.order" issue (bug? just wrong?)
by Alexandre Torres Porres 12 Sep '15

12 Sep '15

Howdy, the "G05.execution.order" example in Pd shows us how delay lines will always delay at least a block of samples, unless you tweak it by using some subpatches and stuff. Well, even though the example works as described, I was doing some tests and didn't get the same results. So it is weird that behaves like that in the example, but when I change the patch or make a new patch it just doesn't behave the same way. Meaning that it will not delay to at least a block in size, but less than that without doing the subpatches thing. See my patch attached. So what now, huh? cheers

gem advanced video keying
by hi 09 Sep '15

09 Sep '15

Dear Pd folk, I am investigating options to improve chroma keying within pd and gem to use within a theater installation. I need more advanced keying features than seemingly possible with [pix_choma_key], like border corrections and smoother edge transparencies. The best thing i found so far is this: http://forum.pdpatchrepo.info/topic/2953/neat-chroma-keying/3 very nice, but i would need more a quality like in readymade video mixers Did any of you program anything like that? Also i'm trying to find out, whether a potential setup with a computer with 4 HD-SDI inputs would be capable of keying 2 HD-live-signals at the same time and overlay that over one HD-live-background. Are there any experiences (hardware and software) from your side, you could share? I would so much love to make this happen with pd and not with an expensive video mixer i would have to buy. Any help or ideas are appreciated. Love to pd, jonny

Re: [PD] Pure Data Buffir~ object
by Fred Jan Kraan 07 Sep '15

07 Sep '15

Hi Julian, Thank you for your report. I am not the expert, just one of the current maintainers if the cyclone set of objects. I think the object works, but maybe not as the Max object. If this is the case I will try to fix it. > Hello, > > I am sorry to bother you but I have an important question about the > buffir~ object. > I hope you can help me with this.

Note '$1' is not literary part of the name, just a placeholder of the first element on the message (=list) you send to the object. If something is wrong here, the console should contain an error message. Also see the help on $-variables. > > I would be verry happy if could help me with this question! If this is > not implemented > and can't be worked around do you have any ideas how to solve my problem? > Thank you very much in advance! The attached patch is an adaptation of the help-patch, including a second buffer to switch to. Yo need to open it and draw non-zero values to get a signal through. It looks like you also have to provide the offset and length arguments, as leaving them out results in zero - meaning no useful convolution takes place. When I have time, I'll check the behaviour of the Max5 object. It might work better or more user friendly. But first on the planning are some weeks vacation :-). > > Regards Julian Jochheim > Greetings, Fred Jan P.S. I added the pd-list in the reply, the main forum for issues like this one (http://lists.puredata.info/listinfo/pd-list).

Documentation of the various GUI objects and what their creation parameters represent.
by i go bananas 01 Sep '15

01 Sep '15

Hi List, to save me the time of doing what several people have already done before, is there a list of all the GUI objects and what each of their creation parameters represent? for example, when i make a simple toggle near the top left hand corner of my patch, it will be listed as: #X obj 7 7 tgl 15 0 empty empty empty 17 7 0 10 -262144 -1 -1 0 1; Of course it's pretty obvious what each part represents, but perhaps somebody has complied a list of all these objects, so i don't have to do it again? cheers, Matt

variable signal outlets and inlets?
by David Medine 31 Aug '15

31 Aug '15

Does any one know how to write a ~ object that has a variable number signal outlets and inlets? The only thing I've been able to come up with is to have a dsp routine that looks like: switch(x->n_sigs){ case 3: dsp_add(whatever_tilde_perform, 5, x, sp[0]->s_vec, sp[1]->s_vec, sp[2]->s_vec, sp[0]->s_n); break; case 4: dsp_add(whatever_tilde_perform, 6, x, sp[0]->s_vec, sp[1]->s_vec, sp[2]->s_vec, sp[3]->s_vec, sp[0]->s_n); break; // so on and so forth... } It feels like there should be a better way to do this. Thanks, David

2nd Annual Web Audio Conference - submissions due October 1, keynote speakers announced The 2nd Web Audio Conference (WAC) will be held April 4-6, 2016 at Georgia Tech in Atlanta. The keynote speakers <http://webaudio.gatech.edu/node/25> for WAC 2016 are Helen Thorington and Frank Melchior. Submissions for papers, talks, posters, demos, performances, and artworks are due October 1, 2015 at 11:59 PM Pacific Time. To submit your work, visit http://webaudio.gatech.edu/node/22 <http://webaudio.gatech.edu/node/22>. WAC is an international conference dedicated to web audio technologies and applications. The conference welcomes web developers, music technologists, computer musicians, application designers, researchers, and people involved in web standards. The conference addresses research, development, design, and standards concerned with emerging audio-related web technologies such as Web Audio API, Web RTC, WebSockets and Javascript. It is open to industry engineers, R&D scientists, academic researchers, artists, and students. The first Web Audio Conference <http://wac.ircam.fr/> was held in January 2015 at IRCAM <http://ircam.fr/> and Mozilla <http://www.mozilla.org/> in Paris, France. The Internet has become much more than a simple storage and delivery network for audio files, as modern web browsers on desktop and mobile devices bring new user experiences and interaction opportunities. New and emerging web technologies and standards now allow applications to create and manipulate sound in real-time at near-native speeds, enabling the creation of a new generation of web-based applications that mimic the capabilities of desktop software while leveraging unique opportunities afforded by the web in areas such as social collaboration, user experience, cloud computing, and portability. The Web Audio Conference focuses on innovative work by artists, researchers, and engineers in industry and academia, highlighting new standards, tools, APIs, and practices as well as innovative web audio applications for musical performance, education, research, collaboration, and production. Contributions to the second edition of the Web Audio Conference are encouraged in the following areas: Web Audio API, Web MIDI, Web RTC, and other existing or emerging web standards for audio and music Development tools, practices, and strategies of web audio applications Innovative audio and music based web applications Client-side audio processing (real-time or non real-time) Audio data and metadata formats and network delivery Server-side audio processing and client access Client-side audio engine and audio rendering Frameworks for audio synthesis, processing, and transformation Web-based audio visualization and/or sonification Multimedia integration Web-based live coding environments for music Web standards and use of standards within audio based web projects Hardware and tangible interfaces in web applications Codecs and standards for remote audio transmission Any other innovative work related to web audio that does not fall into the above categories We welcome submissions in the following tracks: paper, poster, demo, performance, and artwork.

Re: [PD] locality with new [field] object (Jonathan Wilkes)

hey List, Jonathan. > You start with a struct:[struct foo float x float y canvas a b] Then > create a scalar from this struct.

Anyone know who made www.windows93.net? There is a Puke Data icon on the "Desktop" and it runs randomly-chosen patches, but no editing, alas. Fun stuff. JN ᐧ

PD wont start by clicking the PD icon, I have to force quit PD, and still go into Activity Monitor and force quit again (in Activity Monitor PD uses 100% cpu). I have to start PD by clicking on an app I made with PD. Fairly easy workaround, but its not how its supposed to be. Any clue what might cause this? And a fix.
