Hi list, i'm trying to study fft in Pd and still don't understand the numbers produced by the analysis. I'm on Pd "vanilla" 0-40.2 in debian. I just patch this: [float] | \ | \ [osc~] \ | \ | [bang] | / [rfft~] / | \ \ | \ / \ | \ / [print~ imaginary] [print~ real] and then type "0" and "1" in float box and this analysis came to terminal: real: -39.604 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 imaginary: 0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 -0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 real: -39.378 -0.003371 -0.0035941 -0.0035693 -0.0035941 -0.0035851 -0.0035941 -0.0035895 -0.003594 -0.0035913 -0.0035941 -0.0035921 -0.0035932 -0.0035928 -0.003594 -0.0035931 -0.0035944 -0.0035932 -0.0035941 -0.0035934 -0.0035943 -0.0035935 -0.0035942 -0.0035938 -0.0035943 -0.0035935 -0.003594 -0.0035933 -0.0035941 -0.0035936 -0.0035942 -0.0035935 -0.0035934 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 imaginary: 0 0.07316 0.036492 0.02423 0.018069 0.014348 0.011848 0.010045 0.0086772 0.007599 0.0067242 0.0059963 0.0053794 0.0048461 0.0043795 0.0039655 0.0035944 0.0032576 0.0029496 0.0026656 0.0024016 0.0021543 0.0019211 0.0016999 0.0014889 0.0012859 0.00109 0.00090034 0.00071485 0.00053315 0.00035397 0.00017647 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 What this numbers represents ?

Moveable Type - powered by Pd
by Hans-Christoph Steiner 11 Dec '07

11 Dec '07

If any of you happens to be in New York City, drop by the lobby of the new New York Times building. It's open to the public, and there is a great installation there. The sound is all powered by Pd and the text handling and sequencing was done with Python. http://earstudio.com/projects/moveable_type.html Moveable Type Mark Hansen and Ben Rubin (in progress, to be completed in fall, 2007) "Moveable Type, by New York artist Ben Rubin and U.C.L.A. associate professor Mark Hansen, is an artwork commissioned for the ground- floor lobby of The New York Times Building in New York City. When complete, it will be a dynamic portrait of The Times. Statistical methods and natural-language processing algorithms will be used to parse the daily output of the paper (news, features, editorials) and the archives, as well as the activity of visitors to NYTimes.com (browsing, searching, commenting). The resulting refracted view of The Times will be displayed on 560 vacuum-fluorescent display screens installed in the lobby." I'll post more on this when I get it, like video would be nice... .hc ------------------------------------------------------------------------ ---- ¡El pueblo unido jamás será vencido!

gem codec basic review
by patrick 04 Dec '07

04 Dec '07

hi, i am on linux running the very last version of gem from cvs. i am trying to find a good codec for gem. here's my basic research: --------------------------------------- the best codec for quicktime is jpeg: transcode -i yourvideo -y mov,null -F jpeg,,jpeg_quality=70 -o gem.mov gem cpu usage is 38% mplayer cpu usage is 27% ffplay cpu usage is 16% lqtplay cpu usage is 1% ** --------------------------------------- for avi i tried ffmpeg / mjpeg: transcode -i yourvideo -y ffmpeg,null -F mjpeg -o gem.avi gem cpu usage is 33% mplayer cpu usage is 33% ffplay cpu usage is 22% --------------------------------------- the really best codec around is mpeg4: transcode -i yourvideo -y ffmpeg,null -F mpeg4 -o gem.avi gem cpu usage is: crashed** mplayer cpu usage is 16% ffplay cpu usage is 11% * lqtplay seems to make a excellent job for decoding is own codec. would it be possible to make a pix_qt based on the source of this player??? ** anybody can test this codec? that would be my second choice... after lqtplay ported to gem... pat

pdlua compiling on mac
by marius schebella 03 Dec '07

03 Dec '07

hi (hans), I am trying to compile a recent version of pdlua on my mac. I know that last time I did this by putting lua.c into pd-extended and compile it from there, but I don't know anymore, how that is done. the makefile that comes with the tarball does not work for os x, and I also don't know how and what to include. what needs to be done to include this in pd-extended. is this possible at all, since it relies on a lua installation. or could that also be included in the pdlua package, since these files are not very big. thanks, marius.

Re: [PD] Kaossilator clone

Chris, I tried out your FUDIKaosDS today. After displaying the message, "Connecting using WFC data...", the LED indicating WIFI activity kept on blinking but never proceeded. (From the code in wifi.c I am imagining a message is expected to show weather the attempt fails or not.) -- I've looked around and found some notes that older versions of libdswifi had compatibility issues with the following two situations. 1. Adapters which use a 512kb flash for their firmware 2. DS manufactured relatively recently (That's probably me!) This problem is said to have been fixed in later releases of the library. At least a binary I built using devkit1.4.4 I downloaded just today is working fine and I am now very very happy. You may also want to rebuild the binaries you are distributing on your site using more recent libraries. Anyway, thanks for the cool products. -- David Shimamoto > On Thu, Nov 29, 2007 at 11:26:39AM +0900, PSPunch wrote: >> The last time I looked into DS development around Jun.

colored arrays?
by Orm Finnendahl 02 Dec '07

02 Dec '07

Hi, is there a way to color arrays? The message ";array1 color 10 10" isn't recognized and I also couldn't figure out whether there is a way to specify that in the patch file itself (the sources seem to indicate that something concerning the color of an array is saved to file). Can someone help? (BTW: it's on pd-0.39) Yours, Orm
