Pdplay?
by Nicola Bernardini 21 Oct '04

21 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, at the SOb project (http://www.soundobject.org) we're writing some really cool physical model objects which we are soon going to package and propose to the pure-data externals repository (they are GNU/GPL). However, we now have a problem that we want to solve soon: we need standalone versions of some demo applications (possibly running griPD etc.) we did. It would be nice to have a sort of MaxPlay type of thing (how about PdPlay?). I have some ideas on how to do it and it could be trivial, and therefore it is very probable that someone has already done it somewhere. If no one has done it, I'll hack up one solution and report back to the list as soon as it is done (it is going to be GNU/GPL anyway :). Thank you in advance for all the help you will want to give. nicb +--------------------------------------------------------------------+ |Nicola Bernardini | |E-mail: nicb(a)centrotemporeale.it | |GPG Fingerprint = 6AE6 AF21 E160 D9B3 396E EBAC 906C CFAE 4D65 D910| |Neither MS-Word nor MS-PowerPoint attachments please: | |http://www.fsf.org/philosophy/no-word-attachments.html | +--------------------------------------------------------------------+ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: Made with pgp4pine 1.75-6 iD8DBQE9mf2qkGzPrk1l2RARAqi/AJ92NXY9HoDWlMbRcu59RkUQNH8E7gCeLU07 +ocbGJWYRzzrrdQO/cG0BcM= =TT6i -----END PGP SIGNATURE-----

redundancy - just another sound file player
by Thomas Grill 22 Sep '04

22 Sep '04

Hi all, for all who need it, i throw it into the arena. Maybe some of you want to try it out and comment on it - i currently don't have time to work more on it. I have a video/audio installation (together with Martin Pi, see http://freebitflows.t0.or.at/f/exhibition/corrosion) running right now, which suffers from the fact that i could not get one of the PD sound file players to work reliably, so i wrote one from scratch. Attached is a flext-based sketch for a player with the following characteristics: - uses libsndfile (http://www.mega-nerd.com/libsndfile/) and flext 0.4.6 (http://grrrr.org/ext/flext ) - should read _MANY_ file formats - safe loading/starting (no garbage output) - optimized design for many parallel players - on the fly tuneable buffer settings - double buffering for glitch-free seek and file change - currently no varispeed capabilities - currently lacking diagnosis capabilities It is called sfplay~, a naming which should probably change because it clashes with cyclone.... For the future, either i'm going to modify one of the existing implementations (probably reasdsf~) or (with many more features) incorporate it into the xsample package. best greetings, Thomas

planning to attempt to upload 0.38 to CVS
by Miller Puckette 15 Aug '04

15 Aug '04

Hi all, I'm finally going to bite the bullet and try to check my Pd sources into the CVS site. I'm hoping to do this without causing too much damage to the existing CVS tree. Probably I'll just start a branch (named "msp-test" or something like that) and then, once I believe 0.38 is stable, copy it over to the "main" branch. My sources are way broken right now, so I won't be doing this until at least sometime next week. So there's plenty of time for comments as to whether there's a better way to manage the tree... cheers Miller

Re: [PD-dev] Making Wish launch Pd rather than pd launch wish
by 0001＠ooo000ooo.org 07 Aug '04

Hi. I made a simple test some time ago using impd037A2. I added a flag to pd startup so that it started the gui communication part but not the Wish application. This seemed quite easy and harmless. Then the work appeared to be in the tcl side. Starting pd from there is also straightforward. It didin't seem that difficult to make it work, but I think it depends a lot on impd, and that version is quite old. So the question is if the newer version is near to be finished or it is actually hibernating. And of course there are all those new things in deve .... .. gerard > > On Tue, 13 Jul 2004, Miller Puckette wrote: > > > 1. pd now writes "printout" to standard error; this would have to be > > sent to the TK layer and displayed there. > > This feature is part of IMPD 0.37.A, which is rather bug-free -- it's the > version i "released" (tagged) just before beginning to go berserk. > > > I don't know how to do this in the most efficient possible way; maybe > > it's OK just to display a "text" widget and keep stuffing text into > > it. > > IMPD 0.37.A requires the console to be enabled using the -console option, > to which a scrollback length (number of lines) must be given.

finding the centroid of a sound
by Mark Kenny 27 Jul '04

27 Jul '04

Hello all, I have been trying to find the centroid of a sound for the last few days. I am using the fiddle object to capture raw pitch and amplitude, from this Im using the equation sum[FiAi]/sum[Ai], where F=freq, A=amp and i=frame no., this then allows me to get the average centroid value by summing them and dividing by number of frames. The problem Im having is that it's just pulling out the fundamental freq of the sound, I think this has something to do with using the fiddle object, I was looking and there doesn't seem to be an fftin~ object for pd, max/msp also has a centroid object, no such luck with PD i guess!? Is there any object in PD that can supply real, imaginary and bin index on the fly like with the fftin~ object in MAX/MSP?? Thanks for your time Mark

Making Wish launch Pd rather than pd launch wish
by Hans-Christoph Steiner 27 Jul '04

27 Jul '04

I am working on making Pd behave like a proper MacOS X app and in order to do this, I have to make Wish Shell.app launch the pd process rather than the pd launching wish, as it currently does. I was wondering whether anyone has made any attempts at this and whether anyone has any advice about approaches or possible pitfalls. .hc http://at.or.at/hans/

Re: [PD] setable values

Hello, Im only very new to pd, and have now been trying yo solve this problem for a full 2-3 weeks to no avail :-( I know there have been some posts about this but none were too clear... My problem comes when i try to load a simple external, helloworld. I am using MVC++6 and have created a helloworld.dll file ok. But when i try to load it into pd, it reports the error: Load_object: Symbol "helloworld_setup" not found I would appreciate any kind of input very very much, as i trully dont know where to go from here! Thank you for taking the time to read this! Milan H
