stereo -> 8 channel
by potax flan 29 Mar '08

29 Mar '08

are there any abstractions or objects to spatialize stereo (or mono, for that matter) sounds to 8 channel? if not, where should i start looking to make something like that? ta

lowest common multiple of lots of periods
by punchik punchik 29 Mar '08

29 Mar '08

hi, i need to calculate the lowest common mulitple of 50 periods ... i have a patch with 50 syncronic grain generators with a time lag between each other... and i need to calculate when the whole cycle begins again when i change parameters dinamically. how can i calculate lowest common multiple of a lot of numbers in pd? do anybody tried this before... i have no idea, maybe theres other software that can do it easily, any hint? bye ____________________________________________________________________________________ No Cost - Get a month of Blockbuster Total Access now.

FUDIKaosDS
by Chris McCormick 29 Mar '08

29 Mar '08

Hello, Sorry to blow my own trumpet twice in a row like this, but I just found this video somebody made of FUDIKaosDS in action - that's one of the two bits of software I posted about earlier. This video nicely shows off it's capabilities: <http://www.youtube.com/watch?v=fDCYaEc2VL8> It looks like this person is using Pure Data and Gem for the sound and visuals. Best, Chris. ------------------- http://mccormick.cx

Man, that's just a shrunken PowerGlove/P5 Data Glove<http://www.vrealities.com/P5.html>using ultrasonic sensors instead of ir.

cyclone
by marius schebella 28 Mar '08

28 Mar '08

hi (hans), is there a problem with externals/miXed/shadow/cyclone? did you think about integrating this into pd-extended? I think it is a useful object. can you help me, what do I need to do to get it compiled within the pd-extended build system? marius.

place for loaders
by marius schebella 28 Mar '08

28 Mar '08

hi, surfing the cvs I just wondered if "loaders" should be a subdir of externals at all? I can't find a discussion about this in the archives and I also think it is not that important. but shouldn't it go side by side with the externals folder? nevermind... marius.

call for old PC100/PC133 RAM donations
by Hans-Christoph Steiner 28 Mar '08

28 Mar '08

I just did a little hardware work on the build farm. They have very little RAM. In the interest of saving their very old hard disks, I think it would be helpful to have more RAM in them for disk buffering. So, if anyone has any old PC100 or PC133 DIMMs (64MB, 128MB, or 256MB) that are just sitting around taking up space, please send them my way to support the Pd auto-build farm. Then you'll get a lovely mention on the PdLab page and the undying gratitude of the community. http://puredata.info/about/PdLab .hc ------------------------------------------------------------------------ ---- I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. - General Smedley Butler

double question: [pd:compute mean frequency ][gem:howto capture gemwin]
by Patrice Colet 28 Mar '08

28 Mar '08

Hi, I'm giving an hand for a project that intend to transform fingerprints to an image processed by animating the points found by libfprint with the audio analysis of the print's owner voice. Each point animation is rotating by a speed defined with amplitude of the frequency where near the center is the lowest freq and the perimeter is the highest. That part was relatively easy to make, it's just a matter of computing the sum of all magnitudes for each frequency range, with using fft, filling a table with all magnitudes and summing all the values, and after, making an interpolation with the current magnitude, at each block, giving the new z angular reference to a Gem object that is rendering on a simple buffered gemwin and capture an image. Sampling rate have to be set to 48khz to get an integer number of blocks, for an image rate of 24i/s... (48000/24=2000 samples) Now I'd like to get the frequency range of the voice signal, before making the magnitude analysis, to not get 'dead frequencies' in the animation. Also the point's radius will have to change following the current deviation from the mean frequency for the analyzed range. I've attached an archive with patches I've made for processing the animation. So my question is in the title, how could I get the mean frequency of the whole signal, and from each frequency range? That question won't come alone, I'm using Gem for processing the image because I know it well enough, but the rendering isn't really amazing. Each image are written in the hard drive with [pix_write] with [file img/myimage 100(, and I'm never sure about how pix_write will find the img/ folder that is into the same folder than the main patch, and the best quality of a rendered jpg image is really dirty. I'd like to use tiff images instead but I haven't found a CLI yet for building the video with, mencoder can only handle the jpeg from pix_write. Also the [pix_snap]--[pix_record] solution is not stable and compatible enough for this installation. Sorry to be out of topic but anyone knows a program I could handle in a script that builds videos from tiff images? And finally, does anyone know another solution for procesing the image, with other pd externals, or external programs we can handle from pd? Thanks.

Sending data from Processing to PD
by enrique franco 28 Mar '08

28 Mar '08

Hi, I am trying to receive data (integers, floats, strings) from Processing through TCP or UDP. I am receiving something in PD with netreceive but I don´t know what is the format of the data that PD is receiving. How do I have to send it from Processing and what do I need to do in PD?
