The offending object must then be cut and pasted (i.e. reset) to get rid of the nan signal, so try cut/paste rather than restart and see if it helps you next time. sometimes it helps to delete the object, that outputs a 'nan'-signal. but sometimes, as andy said, just cutting this object doesn't help to get rid of the 'nan'. i even had some cases, where i had to restart jackd. i don't know the internals behind pd/jackd, but i can say for sure, that it is _possible_ to turn jackd unusuable with a 'nan'-signal (i don't say, it happens each time). but i can't tell, whether pd or jackd is the cause of the problem (maybe both?). roman I've always considered this something that is inherent in DSP with no sanity checks, as PD often is, rather than a bug specific to PD. The CSound manual mentions this blowing up of filters quite frequently, so I know it happens in other applications. best, d. padawan12 wrote: I get this too.

[PD] Audio drops when using readsf~ with large sound files
Hi List, I have to play simultaneously 8 large soundfile (about 30min at 44,1kHz/16bit, e.g. about 70 Mb each in wav format) on 8 different outputs. I use readsf~ on Windows but audio drops out at every disk access (when the Disk Acess LED of my laptop blinks), and of course this occurs very frequently... I can hear about one minute without drops, then it occurs at a fixed frequency (which I didn't calculate exactly). I tried to load each files with a long delay, tried to defragment, nothing change. I tried to change the bloksize flag, and the arguments of readsf~, with no luck. Is there another external designed to play large sound files, or will I have to cut my sound files into smaller ones and tabplay~ them with a soundfiler ? Any suggestions are welcome !

Re: [PD] Cymatics/Chladni figures simulation
Amazing idea for a project Carl. The way I see it you have two routes. 1) Do a full finite element physical model of a circular lamina and measure the amplitude at many points on the surface. The sand falls into minima nodes iirc . 2) Cheat. Create the visuals by mapping the known standing waves of various modes but missing out the actually building a physical model part. The latter is more feasible for a real-time simulation, but possibly more difficult than using the model. You'll need a much better mathematician than me to help you work out the mapping. In the worst case you could sample the data, do a frequency sweep and fit an equation to each standing pattern which is indexed by the frequency input from your voice. Hope that helps. Imho it's quite a challenging project to pull off, so best of luck. On Tue, 27 Mar 2007 15:23:34 +0100 Carl Knott [EMAIL PROTECTED] wrote: I'd like to write a simulation of a Cymatic Tonoscope.

Hallo, Chuckk Hubbard hat gesagt: // Chuckk Hubbard wrote: I believe Csound is under LGPL, and if I understand correctly the main difference is that people who use parts of it in commercial applications are not required to keep their source open. Someone else will know better, but to my understanding that makes Csound more open than Pd. This depends on how you define open. Pd has a more permissive license than the LGPL. You can embed Pd into a proprietary software and apart from telling, that you did so, you have no further obligations (that's why Max can use parts of Pd inside). With Csound this is not allowed: If you distribute a (possibly changed) binary of Csound, you have to make available your changes freely as well and give us the source to them. So with Csound, you are required to open source changes, with Pd you're not.

You can actually treat the material as continuous, and sampled at discrete points so that the wavelengths are much, much larger than the distance between points, and the steps in time are small compared to the size of the wavelength/(wave speed). In the limit as the difference between spatial samples and temporal samples goes to 0, you get something that represents the real physics of the problem. The real question is just what's good enough? And it would be far more interesting to sample real cymatic figures in the physical world and reuse them for synthesis or whatever. I really liked the video link you posted for the figures. The rectangular plate has some cool symmetries, that would be better than a circular membrane. Plus, it's easier to do simulations of partial differential equations in rectangular coords rather than polar coords. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] HRTF
Was PD previously under GPL? I published my Pd patch together with copies of Pd, zexy, cyclone, and toxy, and the only license file I could find in my Pd folder was GPL. I meant this in exactly the sense you are saying, but I wasn't aware Pd was under the Berkley License. So after software has been released under a license, it is possible to retroactively change the license? Sounds strange to me. -Chuckk On 3/27/07, Mike McGonagle [EMAIL PROTECTED] wrote: I don't think that CSound is more Open that PD, as I believe that Miller has released PD under the Berkley License, which is far more open than the GNU license, it doesn't require any kind of adherance to any sort of policy, you can use it for whatever purposes you see fit, even commercial... http://www-crca.ucsd.edu/~msp/Software/LICENSE.txt Mike On 3/27/07, Chuckk Hubbard [EMAIL PROTECTED] wrote: I believe Csound is under LGPL, and if I understand correctly the main difference is that people who use parts of it in commercial applications are not required to keep their source open.

I can't help feeling like this is a symptom of being more interested in some intellectual problem than in using all of the available tools to make music. Not seeing the forest for the trees, in a way. this is somewhat true, but ignores the fact that Pd is well established _outside_ the computer music community too. you cannot expect dsp-engineers developping the latest-and-greatest binaural rendering system to get into csound. (but they do use Pd) Fair enough. Csound is indeed audiocentric, as am I. I just know Csound has already implemented HRTF, and exists as a PD object, which I thought the poster wanted. If his interest is in pulling an abstraction apart to see how it works, then Csound probably isn't the easiest way. As far as computer music, it's true that I come across few people who are active on both lists, and occasional disparaging remarks about one or the other. I guess the best thing for me to do in that case is to try to show some of the great things that can come from the combination, rather than complaining about negativity. -Chuckk -- http://www.badmuthahubbard.com ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- http://www.badmuthahubbard.com ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list -- Help the Environment, Plant a Bush back in Texas!

[PD] patches/abstractions? [was: Berlin workshop]
Hi Derek, I was wondering if you had gotten a chance to share any of those patches you used for this workshop? I hope I'm not pestering you by asking, and certainly no pressure - it just sounded like a really good time! I would love to hear the kind of stuff you guys were working with - I've never seen any patches that dealt with feedback manipulation yet besides my own little half hearted attempts :) thanks Kevin -- http://pocketkm.blogspot.com ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [PD-dev] including a font file with Pd-extended
Hi, i got a new job as osx admin (among others) for a while now, and we are using a particular font as corporate design. so to ease my job for new osx clients, i made a .pkg that installs the fonts to /Library/Fonts. the fonts work rightaway without needing to restart or recache (just like windowsxp) if you dont want to install fonts to system library (eg. you dont want to use admin rights) you can allso install the fonts to ~/Library/Fonts but the coolest would be to be able to use the fonts from inside the pd dir, without touching any system configs or dirs. but i dont know if thats possible. (like pdf uses embedded fonts, but i assume that pdf doesnt use the system font render system ?) cheers andre On Wed, 2007-03-28 at 00:38 -0400, Hans-Christoph Steiner wrote: Good point, Pd-extended is already using an installer on Windows, so it can just install the font in the proper location, %SYSTEMROOT%\Fonts That leaves Mac OS X, which is tricky since it needs to be inside the Mac OS X .app package. .hc On Mar 27, 2007, at 6:14 PM, David Powers wrote: On Windows installing the font with a batch file would be trivial.

No. So after software has been released under a license, it is possible to retroactively change the license? Sounds strange to me. If you are the copyright holder, you can do whatever you want. In some cases it's very difficult to change the license. For example if there are many copyright holders, like the Linux kernel, you must get them all to agree. Although recently Bruce Perens posted an interesting article saying that this wasn't entirely true - Linus could state that he wished to change the license, and then just change the minds of those who disagreed with the move. He would not have to get every developer, including the dead ones, to state their agreement - silence would be taken as assent. One interesting and not-very-often-mentioned repercussion of this is that you can dual license your own software. For example, I can license my library GPL so that any changes to it must also be GPL, but I can also sell the exact same library to a company under a different, proprietary license if that company doesn't want to adhere to the GPL. That is completely legal, and I think it was what Trolltech did with Qt. Note that if you retroactively changed your GPL licensed software to be non-GPL licensed, people could still fork the code at the last point that it was licensed GPL and continue developing as before.

With Csound this is not allowed I must disagree with this; I think that is allowed with Csound, actually. Under the terms of the LGPL you are allowed to link LGPL code into a proprietary product, and you don't have to show the source to your proprietary product. The difference is that if you modify the source of the LGPL code (e.g. Csound itself) then you must then make those changes available under the terms of the LGPL. With GPL you are not even allowed to link GPL code into a closed source product (the closed source product automatically becomes GPL). With BSD you can do whatever you want, as you say.
