I use fiddle~ for that job. 5th output is a list of partial components, can be split/routed and tabwritten to an array. /knudriis 2012/9/20 umberto torrez <umberto.torrez(a)gmail.com>: > _______________________________________________ > Pd-list(a)iem.at mailing list > UNSUBSCRIBE and account-management -> > http://lists.puredata.info/listinfo/pd-list >

Change pitch without changing length of a audio stream ?
by Charles Goyard 21 Sep '12

21 Sep '12

Hi list, In a installation I'm building, I use veejay (veejayhq.net) for video display, and route the audio of the video for further mixing in pd. This works very well. Under some circumstances, I change the video playback speed. Veejay has a feature called "trickplay" that adjusts the audio to the video length by changing the pitch much like a 33rpm vynil record played at 45rpm. What I want is keep the original pitch of the sound. So I figured out timestretching is what to do. I can send the speed factor of the video to pd. So I tried the timestretch~ external, the vocoder example (got this advice from list archive). They both sound terrible, even with the audio files from the examples (bell.aiff). So is it something doable in real-time or do I have to look for a workaround ? Any advice is welcome. ++ -- Charlot

VideoSecu DVR Security board with 3 cameras plus PD
by Billy Stiltner 21 Sep '12

21 Sep '12

Is it doable? The cameras are black and white, the mics are great except for the hum from poor insulation, the infrared had probably half blinded me, it allready has some linux on it but the network interface is through an activex browser dohicky, Should I just throw preloaded 12.04 Ubuntu Sstudio in there and see how it picks up on whats in it becasu I can't find any info on the board but it has an ARM SATA controler it looks like with a 2TB drive that my linux can not understand the partition tables on. It would make for a nice video piano and a triangulated sound wave input. Should I just use the drive to install a fresh copy of windows so I can scan(dagone Lexmark) in my patch guidemap drawings or what? Maybe I can grab pictures from the scanner with pure data if I can figure out how to get it to stop sayingCannot Retrieve Application List! Maybe that is why Pure Data does not understand strings. hahahahaha! j/k about the strings.

strange GEM behaviour
by Marian Weger 21 Sep '12

21 Sep '12

Hello list, I just stumbled across some strange behavior of Gem. I attached a small patch to demonstrate this problem. If multiple [pix_image] connect to the same gemhead (with separator), changes in "pix_..."-effects that are connected below get only effective for the first one. The resulting texture of the other branches gets only updated if the image is reloaded. Of course, everything works fine, if i use individual gemheads for each branch. Is it a bug or a feature? How can I solve it? Tried it in Pd-0.43-2 with Gem 0.93.3 on OSX and Pd-0.42.5-extended on Windows. thanks! marian

Hello all, I have been looking through all the online documentation I can find, but still unsuccessful at compiling simple external (hello world example). I have looked through all the OSX/Windows docs to try and figure out what configuration my make file should have, but no luck. Needless to say I'm a n00b to creating my own makefiles.. any help is greatly appreciated! Thanks JZ
