I'm guessing there are about 200-300 of us.

audio to visual art
by robertgarvin＠bellsouth.net 14 Mar '05

14 Mar '05

I had an Idea... (again in the shower.. great place for inventing): What if (like GEM) you could use PD to control certain aspects of a printer. for example, a set of number boxes would control color, and another set would control the catridge rack (the thing that moves to control the lateral movement of the cartridges), and another set would control the paper mover.. uses? 1. Possibly, if you wanted to, have PD instead of printing to the main window, to the printer. 2. Draw pictures directly to the printer 3. use the printer as a visualizer for music performances/applications. (i.e. "convert" audio art to visual art.) Just a thought -Robert

using recorded positions as wave table
by pun chik 14 Mar '05

14 Mar '05

hi , im trying to learn pmpd, ive read in the tutorial that movements of particles can be used for create new sounds... "The movement of one of the masses in the figure 8 membrane is recorded in the pd environment. Sound can be produced using this movement by using the recorded positions as a wave table." do anybody has an example patch of this??? thanx punchik -- pun chik punchik(a)fastmail.fm

Interpolating to a higher sample frequency
by Niklas Saers 14 Mar '05

14 Mar '05

Hi, I am at the moment stuck with a 44Khz sample rate, which is fine with the sounds I'm working with (in the 800-7000Hz area) but which makes 1000 sample ffts too slow. So I wondered if anyone's done audio interpolation with Pd or how you'd go about doing this. Right now the only option I'm aware of is writing an external with the interpolation and try to spit out the audio at a higher rate than it comes in. Will Pd at all allow for this, or is it locked to the sample rate of my hardware? I've been googeling for externals that do this already but found none. For the interpolation I was thinking of using line~, but it doesn't seem fine-grained enough, asking for milliseconds. Speaking of fft, can anyone point me in a direction of how to narrow the analysed bandwidth down to the 800-7000Hz area that I'm interested in? Still reading up on it, I'm hoping that should let me get a higher precision with less data. Sorry if this is all very newbie. Cheers Nik

project
by Scott Hildebrand 14 Mar '05

14 Mar '05

i'm wondering if there's a project that anybody has in mind that a lot of people could contribute to? i have some spare time and i'd like to do some programming. anyway i get the digest so please email me directly. i can definitely help with 3D audio. scott __________________________________ Do you Yahoo!?

Ian, i want to thank you for writing what i don't have time to write.. )) and, obviously you've been compiling PiDiP since a long time ago, but i must update your instructions ( which are all right , BUT BUT ....) ffmpeg is now totally optional as we use ogg/theora for video streaming from now on, i was in the world social forum in Porto Alegre to stream with it, it worked great, people around the world could hear from Chavez and what the fuck is going on in these idealistic countries )) do you know of autolab : http://www.midiatatica.org/autolabs?? on a side note, as europe and the US are still drenched in efficiency, i'm still looking for people drenched in utopia... )) well, what were we talking about? yes, PiDiP installation is now much more easier and you can even try an 'apt-get install pd-pidip', should work with the right sources ( thank you al-caedes ) ya esta, sevy > Once you've installed PiDiP a dozen times or so it becomes straightforward.

More or less like > OpenDE's possibilities: > http://opende.sourceforge.net/ode-latest-userguide.html well, in fact pmpd use only ponctual mass : this mean that all masses does not have any volume. they are not spherical. there reprensentation can be whatever you wish. intruducing rotation would mean introducing shape etc. the equations then became to much complex to solve them in an easy way. so, using ODE or other 3D dynamic software is much more complex than using pmpd. you can also use breve3D ( http://www.spiderland.org/breve/index.php ) if you wish an openGL + physical modeling tools. bridges with pd can certainly be made. doing such simulation tools is a very huge work, i don't think i'll be able to do it someday. > 2.

This is somewhat anecdotal and I have no numbers to back it up, but way back when my live rig used to consist of a pentium running home brew looping software (before i found out about pd) I found that under linux I could only get it to perform as well as the same software on the dos box if i switched off every uneccesary process and ran in single user mode. I guess this is self evident, but something that might be useful for those wanting to run pd on old hardware. Running as root with the then 'low latency' patches was a help too. Not sure what the kernel scene is like now though. Best regards, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

PD 4 DOS

Hi Frank, > > I've never heard of a Pd for DOS, but why not install > Linux on that machine and run Pd in the terminal without I have tryed to install mandrake (I think 9, about a year ago) on it, but could not figure out how to get the laptop screen driver installed, so I went back to windows. > X. This should work just fine, so to say. For Linux you > normally need at least a 386 CPU. > I could try again with planet ccrma, which version should I use 8 or 9? It is only a 120mhz pentium1, do you think that would meet the minimum system requirements? -thanks Beau

Interpolation in xgroove~
by Frank Barknecht 12 Mar '05

12 Mar '05

Hi, I'm not quite sure how xgroove~ handles 4-point interpolation compared to tabread4~ in regard to table length. tabread4~ requires indices from 1 to size-2, so if I want to tabread4~ some table from m to n then the whole table must be at least "1 + |n-m| + 2" elements big, IIR. Is the same required for xgroove~i in 4-point mode? Or can I skip for example the first sample or the last two? And if the table is then just as big as the range set in xgroove~ (say by using the "all" message): How will xgroove~ interpolate at the ends? By just wrapping around to the other end? Some kind of wrapping interpolation actually is what I'm after, as I'm in need of an interpolation dynamic wavetable oscillator and xgroove~ handles dynamically changing wave-table contents much better than tabread4~. If someone has suggestions for alternative approaches to dynamic wavetable oscs, I would welcome them, too.
