Re: [PD] webcam on OSX
by Sam Roig 14 Feb '04

14 Feb '04

Thanks. Knowing that it's possible I gave it another try with pix_video, but had no better luck. I am also using the webcam driver from http://webcam-osx.sourceforge.net/. Does anyone else on the list know which object gives access to the webcam? Do I need to provide in some way (a message to the object) the driver to be used? ::: sam ::: On Thu, Feb 12, 2004 at 12:13:20PM -0800, Hans-Christoph Steiner wrote: > > I don't remeber the exact object either and my mac is in the shop, so I > dont' have an example patch.

nSLAM release: pdjimmies v0.1 / multi-channel audio streaming
by zack 14 Feb '04

14 Feb '04

nSLAM release: pdjimmies v0.1 / multi-channel audio streaming A library of abstractions and externs, which provide shortcuts and functionality for DSP programming in Pure Data, and example applications for multi-channel audio streaming is available for downloading at: http://toto.sat.qc.ca/eng/nslam.html Pour les francophonos: http://toto.sat.qc.ca/fra/nslam.html The “pdjimmies” library, developed for Pure Data by Zack Settel (of the SAT, Montreal) to ease the pain of DSP programming, immitates the original “jimmies” library, which was developed by Zack for the ISPW (Ircam Signal Processing Workstation) system, and later ported to MAX/MSP by Richard Dudas. The "pdjimmies" library conatins a subset of “original jimmies" immitations (pbank, reverb, harms, etc.), as well as new objects for dealing with multi-channel audio. The missing "original jimmies" immitations will be added in a subsequent release of “pdjimmies”. “pdjimmies” is provided with the “nSLAM” audio development release, developed at the Societé des Arts Technologiques (la SAT, Montreal). nSLAM is an open-source audio bundle for multi-channel audio application development, developed by the SAT Audio Group. At its core is a library of low-level DSP objects called “pdjimmies “; included in the release is documentation, help files, and example applications for multi-channel audio streaming (using oggvorbis/pdogg~, developed by Olaf Matthes). note: binaries are included for mac osX and Linux -Z Settel

PD in linux with HDSP 9632
by Melissa Corso 13 Feb '04

13 Feb '04

I have finally gotten PD to start in Linux using the command jackstart -R -d alsa -d hw -r 44100. I then start PD and no longer get the Audio I/O stuck..closing. However, when I try to make any patch or even test audio no sound comes out. I am using an RME HDSP 9632 audio card. Again PD appears to work but I can't get any input in the HDSP mixer and no signal in the playback. So I'm not sure what is going wrong. Any help would be appreciated. Thank you- Melissa Corso ____________________________________________________________ Find what you are looking for with the Lycos Yellow Pages http://r.lycos.com/r/yp_emailfooter/http://yellowpages.lycos.com/default.as…

Text Functions
by Bradon Webb 13 Feb '04

13 Feb '04

Hello, This may be slightly OT. I was wondering about text cababilites PD has. I was wondering if PD could recognize words somehow, so that say I gave it three letters A, B, and T, it would result to me BAT, or TAB, but not BTA, ATB or ABT. As the latter are not words in the english language. Also maybe It could do something like a spell check where letters that are close to forming words, would be corrected and output. I am looking to have some kind of perfomance with the text. I like the structure and organizational design in PD so that is why I thought PD. Eventually I may want sound to react to specific words. I am not an experienced programer, and PD is all I really know at the moment. I think there is nothing in PD that will do this text function, but is there anyway for me to use it in conjuction with a spellcheck aplication or dictionary application. maybe I could write to a text file and have a spellcheck check the document and save document and read back into PD. The whole structure should be somewhat autonomous, meaning I don't want to have to manually pull up the files check them and save them. I am on either Win XP or Linux. thanks for any help, bradon __________________________________ Do you Yahoo!? Yahoo!

High pitched clicks when changing frequency
by Melissa Corso 13 Feb '04

13 Feb '04

Using PD and iemlib software, I have created a high pass filter. However, when testing it, I get these high pitched clicks when the frequency changes. The clicks occur when output goes to approximately 150 and is clipped. I want the cutoff frequencies to change at certain intervals without muting the audio. If you have any suggestions it would be greatly appreciated. Or if you have any further questions please let me know. I have attached the filter so that you can see exactly what I have done.

pack and messages with respect to route
by thewade 13 Feb '04

13 Feb '04

I just wanted to either ask about what Im doing wrong, or point out a discrepency in PD. the [$1 $2< object behaves differently then [pack 0 0] with respect to [route s s] If I connect the pack to the route (in my case, pack looks like [pack s 0 0 0]) then route does not route my signal, where as if I connect my pack to a message [$1 $2 $3 $4< then route works fine. Whats up with that? Also, could anyone describe the format of the real output of FFT, so I can start to write an external to latch onto specific bins (not just the loud ones, such as with fiddle~) Thanks! -thewade

Gem references
by shreeswifty 13 Feb '04

13 Feb '04

Hi I am preparing a short paper on the use of GEM in our global Access Grid performances, most recently with Korea,Japan and Austrailia. I am looking for any and all references to presented papers that we might use to give a brief history of GEM, its applications etc. Any siggraph references or conference papers would be great. Please let me know or link me to anything you are willing to share cheers~ Pat

Re: [PD] convolution external url
by Jeffrey Hildebrand 13 Feb '04

13 Feb '04

sorry about the mixup, here's a new speedy server... http://www.pulpgames.com/~klezmer41/ currently only the windows version is on there, but the demo can be run on a windows machine that doesn't have pd installed because pd is included. before i had a problem with this external and a missing msvcrtd.dll file, but hopefully that isn't a problem anymore. anyway i'm going to be working on this and eventually there will be more downloads, but for those hungry for some spatial audio here's a demo and the source code. let me know what you think about it!
