Re: 64bit pd stuff

First I appologize for missing that last email. I was dealing with the sharp stick my ex-girlfriend stabbed into my heart... > I\'m not having much luck with 64bit PD.

Miller PD 0.38 or 0.37-* have this problem with tables > and soundfiles. I havent gotten PDP to work, but I havent tried. Im still trying to get Gem-0.91.0 built. The configure script wont find any 1394, my quicktime, or anything else. I did hack the configure script so it gets past GL detection though... Miller said that the pd from iem builds on 64 bit architectures, so I built pd-0.38-0test10. I havent tried to use tables yet. I have seen the soundfile thing, but I havent tried to debug that yet. Im still getting xruns with jackd that occur intermittently - may be an acpi thing, I dont know. I also get weird a/d/a sync errors in pd which nobody seems to know about. > Also, I\'m still lost on this HDSP thing, but I am pretty sure > it is cardbus-parameter related.

Like I said earlier, I just downloaded and built 2.6.10-rc2-mm1. Every kernel after 2.6.9-rc2 should have hdsp support for x86_64 I think. Thanks Takashi! I dont know what pcmcia-cs is. I just turned on alsa and hdsp in the kernel .config. Fedora Core isint happy I did this - It wants me to use RPMs, but that is to slow for me. 64 bit is a pain for us forrunners... Good luck, -thewade

tabreceive~ and block~ objects
by Phillip Stearns 04 Dec '04

04 Dec '04

Hello! I'm fairly new to PD and am exploring some of the simpler objects involving reading from arrays and I ran across the [tabreceive~] object. The help file said that I could use the [block~] object to resize the audio buffer to used in [tabreceive~] but I haven't been able to get it to work. Maybe I'm not sending [block~] the right messages. I can get sound out of [tabreceive~] but there just wasn't enough information in the help file to take me beyond that. So here are the questions: How do I use the [block~] object (kinds of messages to use)? What can the [tabreceive~] object do (functions, limitations) and how do I access those functions? Thanks Phil --------------------------------- Do you Yahoo!? Take Yahoo! Mail with you! Get it on your mobile phone.

Nintendo gun with Pd ?
by Alexandre Quessy 04 Dec '04

04 Dec '04

Hi all, Pd is quite amazing, and we can do just about anything. It's interesting to offer something else than keyboards to interact with electronic art. What about a Nintendo or SEGA gun ? Have you heard about an object of a software that could help us make an object out of it ? I guess it would mean to display subtle symbols or sweeps in a Gem window that would be recognized by the gun and transfered to the program so that we get to know the area that was shot. Such a remote control would be interesting for "virtual reality" using Pd. Thanks, Alexandre Quessy Montréal, Canada listes(a)sourcelibre.com

Re: [PD] horizontal video lines
by sara kolster 04 Dec '04

04 Dec '04

Hi Chris / list, At http://www.umatic.nl/pdp_picts.html you can see what a such a horizontal line looks like. Sometimes you can get similar results when you change the field dominance when you edit / compress video. See quote below from a mail i got from Miguel Carvalhais. <quote> usually it comes from swapping the field order in videos, so if your video standard/codec uses lower field before upper field and you compress the video the other way around (upper first) then that means that by reversing the fields you get a bit of a flickering in the image as within each frame you're seeing reversed fields.. in a simpler explanation: when you have a sequence of frames 1 - 2 - 3 - 4 - 5 - etc you have a sequence of fields within each frame: 1L - 1U - 2L - 2U - 3L - 3U - 4L - 4U - etc... each field containing half of a frame... if you number this correct order of fields then you get: F1 - F2 - F3 - F4 - F5 - F6 - F7 - F8 - etc when they get swapped, this happens: F2 - F1 - F4 - F3 - F6 - F5 - F8 - F7 - etc so whenever we advance in time, we also skip backwards within each frame... this effect is not too visible if there's not much motion but in takes with more movement it can become rather obvious... </quote> I don't know how pd handles the field dominance of the video-input, but maybe it could help if you could manually change the field dominance from: not set, to upper and lower. Just a thought, don't know if it's possible and if it would fix the problem.

understand soundfiler
by Lazzaro N. Ciccolella 03 Dec '04

03 Dec '04

Hi all, I try to write a message correctly in order to load a sound file in one table using the "soundfiler" object _on windows_ . I have the following problem: if I try with |read -resize c:/Documents and Settings/bla..bla/01.wav table23( | [soundfiler] I have the following message of error: and: no such table then I have retried with closing path in quotes ("): |read -resize "c:/Documents and Settings/bla..bla/01.wav" table23( | [soundfiler] but I obtain the same error. If instead I use the object openpanel in order to create the message in this way: |bang( | [openpanel] | |set read -resize $1 table23( and after bang the result: |read -resize c:/Documents and Settings/bla..bla/01.wav table23( it work nice, but to my eyes the two messages seem equal. where I mistake ? I cannot use the object openpanel because I am using pd without GUI and pd must take the name of the file through a tcp connection. thanks for whichever aid bye -- Lazzaro

Dear all, I know this is possibly a simple request, but i am looking for a way to shift phase of a signal by 180 degrees in realtime, in order to implement cancellation of said signal, any advice would be appreciated, Alex Impey.
