pdp codecs
by martin pi 16 Jan '03

16 Jan '03

hi, i have to confess that the codec problem seems to be (partly?) caused by my half debian half tar.gz installation of libquicktime. if i save any pdp created .mov files i am able to play them back using lqtplay - the files i wanted to use are not played back for some reason (although mplayer plays them and they were encoded on osx with media cleaner, so they're native qt) so maybe it is a problem with the compressed header or something like that since the lqt output says: INFO: playing 01b.mov info: Made with Quicktime for Linux WARNING: no video stream WARNING: no audio stream ERROR: no playable stream found while mplayer says: (btw: the file should not have any sound) Playing 01b.mov Detected QuickTime/MOV file format! Compressed header uses zlib algo! Compressed header size: 1715 / 3730 -------------- MOV track #0: 45 chunks, 339 samples MOV: Found unsupported Field-Handling movie atom (10)!

syncgrain~ for windows
by eskogen＠usfamily.net 16 Jan '03

16 Jan '03

hi fellas, i updated the syncgrain~ port at audionerd.com. i've had some crashiness when switching tables, but i'm looking into it. right now, it's just a debug build of the code direct. perhaps if i have some more time i'll see if i can optimize it. i am a little confused on the operation though. i didn't actually look through the source code much yet (ha!) and i can't figure out how the pointer rate is proportional to the change in speed. for instance, i want a sample played at %50 speed, i would assume a value of 0.5. this does not hold true however. any notes? for those of you in the minneapolis/st paul (MSP) area, i'm playing a set with PD thursday night. i'm predicting about 30 minutes of weird noises and technical problems. e-mail me for details. --eric http://www.audionerd.com/projects/pd/index.html ------ http://USFamily.Net/info - Unlimited Internet - From $8.99/mo! ------

pdp, pidip, quicktime
by martin pi 15 Jan '03

15 Jan '03

hi, tried to test pdp and pidip today - v4l works perfect, yet i did not find any qt codec supported by either pdp_yqt or pdp_qt (though other software using the same lib is able to play most qt codecs). response was always: pdp_yqt: opening /home/pi/mov/01.mov pdp_yqt: no video stream or pdp_qt: opening /home/pi/mov/01.mov pdp_qt: ERROR: no usable video stream found. using the newest versions of all software mentioned. martin martin pi http://attacksyour.net/pi www.machfeld.net

Re: [PD] visualization
by Norbert Math 15 Jan '03

hello theres, there are some objects for sound visualization around, see Sonogram~ and cooled~ by Yves Degoyon http://ydegoyon.free.fr/ the framestein library http://www.framestein.org/ by Juha Vehviläinen - has a sonogam too. you may also use fiddle~ to detect the pitch(es) of incoming sound, and build up or alter data structures depending on its output. n > --__--__-- On Wed, 15 Jan 2003 pd-list-request(a)iem.kug.ac.at wrote: > > Message: 8 > From: "theres" <sonnenhaase(a)web.de> > To: pd-list(a)iem.kug.ac.at > Date: Tue, 14 Jan 2003 19:49:07 -0000 > Subject: [PD] visualization > > I want a analysis of an incoming sound and a visualization of it like it is shown in the > documantation (in the data structure example), how is the best way to do it?! > many thanks in advance!:-) > > > > --__--__-- > > _______________________________________________ > PD-list mailing list > PD-list(a)iem.kug.ac.at > http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-list > > > End of PD-list Digest >

Drawing in tables?
by Dupras, Martin 15 Jan '03

15 Jan '03

I'm just spent several weeks teaching PD and ran into many questions that I could not answer at all. 1) in what cases is a table drawable? I thought previously that it depended on the resolution of the array, but apparently not. I can sometimes draw in a table that contains 65000, but sometimes not. Can someone explain? 2) in the arrays examples, there are some messages that can be sent, such as sinesum and cosinesum, to fill a table. Are there any others? I could not find any. If there aren't any others why is that, is that from lack of need or because of a particular difficulty in implementing such things? I'm thinking in particular that something like the gen routines in Csound would be invaluable. 3) I have never used the text editor in PD, and a student asked me what it was for. Looking at it, I realised that I don't have a clue either. It certainly does not do what I thought it would. Anyone care to explain what can be done with it? Thanks! - martin

I want a analysis of an incoming sound and a visualization of it like it is shown in the documantation (in the data structure example), how is the best way to do it?! many thanks in advance!:-)

getting started
by Alex from idoia 14 Jan '03

14 Jan '03

Hello there, I am getting step by step into PD and have a couple of newbie questions before getting started: I have read the Miller' s doc but could not find any 'reference' doc in which all available objects are explained. Maybe there is none ? also, as I come from Max I wonder to know if all object in Max work in PD. At last, I would like to realise a very simple patch that record audio from my sound card into a aiff format (I am on Mac) but using a midi click set by the user to start and stop the recording( like any basic sequencer program), the way I can do some overdubbing on top later on. Is there already some patches that could give me an idea of how to start ? Thanks a lot for your time. Alex

Patch design methodology tips
by David McCallum 14 Jan '03

14 Jan '03

Hello all in list-land, Part of my undergrad thesis is a little paper on Max-type language (Max, Pd, jMax) patch design methodology. Things like how to go about designing effective patches, design rules that make debugging easier, patch organisational models, etc. The aim of the paper is to come up with a set of rules for designing "effective" patches, as a guide for beginners and also as a set of tips for seasoned users. I've been recently codifying my own methods for the paper. And any thoughts, tips, or insight that any of you can offer about your own methods and practises would be greatly appreciated. David . .

PD-announce list
by Hans-Christoph Steiner 13 Jan '03

13 Jan '03

I had a thought about the PD-announce list. I am a big fan of announce lists since you can keep track of a project without having to get a lot of email. But the pd-announce list seems to accept posts from anyone, so it makes it a higher volume list when people post replies, and also allows spam to be posted to it. I think we should restrict posting access to the pd-announce list and maybe at a Reply-To: pd-list to pd-announce emails. What do y'all think? .hc
