Re: [PD] Handling numbers read from a file
There's a simple solution to know the size of an array in Pd vanilla (it has been posted on this list before). If your array is called example, send a bang to [expr size(example)] Hansr At 16:03 2/03/2010, Matteo Sisti Sette wrote: As all my data are numbers, [tabread] should work fine. Although in this case, I do not know how to know the number of values in advance to resize the table prior to loading the data. If you store the numbers one per line in the text file, then you have two options: A) Load the file, then bang [textfile] in an [until] loop (until the end is reached) and resize the table at each bang by incrementing its size by one as you add one more number. Quite inefficient since I guess it may have to reallocate memory at each resize B) Load the file, then do one first scan of [textfile] (banging it in an [until] loop) just to count the numbers, then resize the table to the number of counted elements, then start all over again to store the numbers into the table If, on the other hand, you store all the number in one list in the text file, then you can load it, bang [textfile] only once, and use a [list length] to know the number of elements and resize the table accordingly, and then prepend a 0 to the list and send the whole list to the table to store the elements. I think the latter solution should be a little (or significantly?) more efficient. -- Matteo Sisti Sette matteosistise...@gmail.com http://www.matteosistisette.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

Re: [PD] A better pitch shifter?
I've used this pitch shifter quite a lot for a number of different things -- how you use it seems to depend completely on context. For instance, if you're shifting mostly sustained sounds (so that attacks aren't so present), you can use a larger window size, which reduces some of the modulation artifacts you get when you use a lower size. You need the lower size for fast things, or things with strong attacks. I once experimented with trying to get the window to match exactly period boundaries of the incoming sound (to reduce the modulation completely), but it really only works with electronic sounds where you can be absolutely sure of the frequency. I have had luck in some rare cases mixing the output of two pitchshifters set to the same transposition but different window sizes -- again, no difference in latency, but it can help smooth things out if you're really aggressively pitchshifting something (like, by a perfect 12th), where presence isn't really something you're going to be able to attain anyway. I now keep several of them around with different settings for different contexts. Matt Hi all, I tried making a mult-delay pitch shifter once.

Then I connected the outlet of the [pack] to a message box with the following contents: [wave1 sinesum $1 $2 $3 $4 $5 $6 $7 $8 $9 $10] I added a tabread4-mimic and could display the wave in an array visually. So nice so mysterious ( at least for me ;) ) Slider 1 to slider 8 are working as exspected, moving slider nine and ten results in nothing but the pure sound of silence (visually spoken...). For what I read about [pack] the inlets sequence follows the arguments or in my case inlet #2 up to #10 are exspecting float arguments, which are given by the vsliders. A [BANG] at inlet #2 send a bang into the pack. But the reason, why slider #9 and slider #10 are on holidays is not very obvious to me. The aim of all this should be a wave, which reacts on changes of each of the sliders instantly without sending an extra bang. And I want to have all slider (better: much more than ten) working. And if there is a way to normalize the result instantly I would one step nearer to eternity ; I know, that there are obviously far better and total different ways to accomplish what I want to acchieve, but for the first I only want to understand, why this beast is only running on eight instead of ten legs (my be a spider therefore... ;) Thanks a lot for any help in advance!

Re: [PD] To pack or not to be packed that is the question ! (?)
The [pack] object and the [trigger] object should be separate. First create this: [pack 0 0 0 0 0 0 0 0 0 0 0] then each number box should look like this: [0] | [t b f] where the f outlet is connected to the corresponding inlet in [pack], and the b outlet is connected to the first, hot inlet of [pack]. [pack] only gives output when the hot inlet has input, so the bang message sent after the float triggers it and gives output no matter which number box you change. Read more about hot and cold in the HTML manual or in the FLOSS Manual for details. Or see attached patch. Best!

Re: [PD] To pack or not to be packed that is the question ! (?)
The first slider does not need a [t b f] because it is connected to the HOT inlet already. When it sends a number the first inlet, the [pack] gives outlet. The others use a bang message so that [pack] sends output with all the numbers it has stored in the COLD inlets already when the bang goes to the HOT inlet. This is one of the most important concepts in Pd, so pay close attention to this! Best, Derek PS. please keep this conversation on the Pd list so others can learn too!

Re: [PD] To pack or not to be packed that is the question ! (?)
Hello Meino, please read the Generating Waveforms chapter again: http://en.flossmanuals.net/PureData/GeneratingWaveforms specifically the section titled Using Sinesum. You'll see that the third element of the sinesum message, where you have your $1 now, is the length of the table (which is set ahead of time). The fourth element, your $2, is normally a value of 1. That is because the first harmonic is usually 1 when generating a bandlimited waveform. Of course, you don't have to fix it at 1. But you do need to have the table length! So insert the number 2051 after the word sinesum in your patch, and you'll be set.

[PD] gem and gmerlin on Ubuntu
I've been struggling for the past few hours with ffmpeg trying to create an video file that Gem will accept that contains an alpha channel from a series of tiff images. While searching for answers I found some messages that mention that new versions of Gem are using gmerlin as an a/v decoder which should open it to many more formats. I'm currently on Ubuntu 9.10 with pd-extended version 0.42.5-extended-20091114. I probably installed it from a .deb package somewhere. Gem info: GEM: Graphics Environment for Multimedia GEM: ver: 0.93.CVS GEM: compiled: Nov 14 2009 Is gmerlin support included in that Gem version? Is it a simple matter of enabling it? Are the Gem .debs with it built in? Will I have to compile from source to get what I want? Also, I'm fully open to any suggestions on how to make alpha-channel enabled videos that Gem can read. My ffmpeg line for jpeg sequences is: ffmpeg -f image2 -vcodec copy -i sample%04d.jpg sample.avi If I try the same with alpha enabled .png files, Gem throws errors about MPNG: AVI reader : Stream 0 vids : MPNG (0x474e504d) 117 chunks (0.46KB) reader : Initialized video stream (chunk tblsz: 117, fmtsz: 40) codec keeper : Found 5 plugins (/usr/lib/avifile-0.7,A:22,V:32) codec keeper : CreateVideoDecoder(): Unknown codec 0x474e504d = MPNG Thanks, -martin ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] Variable CPU?
Hello I made a little discovery. It works with pd-extended and with pd-vanilla+GEM. Il have a MacBook Pro 2.66 GHz Intel Core 2 duo, with Mac-OS X 10.5.8. When I open one of my video-patch (it works with any one of my video or sound patchs), if I look at the CPU utilisation, I get something like 7 ou 8. Nothing is running, the GEM window is not even created. If I wait something like 1 or 2 hours without using pd ; or, if I pause my computer (I close it), wait 30 seconds, and open it, I get something like 0 or 1 as my CPU. Then, if I use my patch, when I get normally CPU = 70, and with this method I get CPU = 20. And of course, the performances are absolutely not the same. In fact, without this method, my MacBook Pro is not very much more powerful than my old 1.33GHz PowerPC G4. It works with audio-patchs too. There is an other method : if I turn dsp on, and then off, I get the same result. This method can't work with audio-patchs, because when I turn on dsp I always get high CPU. So I have to turn dsp on before pausing and turning on my computer. (I don't know if I'm clear...) Weeell, I realized that it works with my PPC too, but the differences are not so important. Has someone any explanation? excuse me for my english T ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] diff frame from previous frame with Gem
wow!
amazing patch/idea!
im creating a new performance with dancers, and this patche looks
super-conceptual! it only captures the moviment! wow!
maybe im a bit stuned ;). but im just expressing my feeling about your
idea hans!
cheers guys!
ps: take a look at this video: http://www.youtube.com/watch?v=FTvqaHVFBlo

Hi,
I think I got close, but did manage to create a bizarre effect:
I got just a white frame.
I think you should cycle the placement of the frames in the buffer (so you
always keep the last and new one) as well as first send bang then anything
to the pix_film ..

flicker comming from i dunno where :/
