Hi! I just want to ask if there is a patch for pd 0.36 to enable jack support. There is no such option in the configure script . Thanks, Anton

frequency-shifter

Hi all, did anybody implement a frequency shifter using single-sideband modulation with Hilbert-Transform in pd? If so, I'd be very much interested in it. -- Orm

external's struct question/ convolution question
by Jeffrey Hildebrand 20 Dec '02

20 Dec '02

In a convolution thingie I'm working on, I'm storing "overlap" in the external's struct. Will this data be saved until I write over it? I need some direction in understanding the flow of how an external works. I've found that the very beginning of my external code doesn't get read again once the external code starts working. Other than that I don't really know what's going on in Pd. To be more precise, when I change HRTFs then I always get a CLICK. For those of you who understand the overlap-and-add method, what I do is store the overlap of the previous HRTF and then add it to the next block of convolved coefficients. I'm having a hard time debugging this and finding the source of the click. For instance if I leave the location of the source sound the same, then there are NO clicks and the audio is perfectly smooth. I'm using the sliders to change location; one for azimuth and one for elevation. Any help/ideas is much appreciated! Scott

Broken Debian package PD 0.36.cvs-2
by 220hex 20 Dec '02

hi! I'm trying to install the PD 0.36.cvs-2 Debian package with dselect, but it's broken and can't be installed. It complains about a missing package called libjack0 that's not available. Any hints? I'm running Debian unstable/testing and the demudi rep. in apt/sources.list .gif

Re: [PD-announce] Paradiddle 0.1: a Cocoa interface for Pd
by damion romero 20 Dec '02

20 Dec '02

Adam, The Paradiddle thing is really great (now if I could only get Pd to do anything I really want it to do) I've had some luck using it to make an app to control a pd patch. It would be cool to see it be able to receive as well as send. I need to figure out more about how to use project builder before I can give much valuable feedback... It would be ideal if projectbuilder could somehow make an app that could run pd inside itself, without having to launch pd itself and could stand alone... Thanks, Damion "I'd appreciate feedback from interested parties on where to go next. I can imagine a variety of directions: - auto-connect and better integration as a Pd "launcher" - more complex "expert" modes for those already familiar with Project Builder (not my favourite direction, but a possibility) - receiving feedback from Pd"

a safe sound file loader with readsf~
by eskogen＠usfamily.net 19 Dec '02

19 Dec '02

hi list, as per miller's advice, i've tried to make an abstraction to load .wavs into a table using readsf~. i start by resizing the table to fit the wav size, but this seems to always turn the audio off (at least, i think it's the resize that's doing it). so i'm getting sporadic results. any pd guru care to take a look and tell me what i'm doing wrong? thanks, -- eric PS: thanks to all on the list who have helped me sort out my questions. i'm slowly getting the hang of pd.. ha SAFELOADER: #N canvas 407 115 313 546 12; #X obj 31 16 inlet; #X msg 149 395 \; \$1 resize \$2; #X obj 149 350 symbol \$1; #X obj 149 377 pack s 0; #X obj 31 204 readsf~ 2; #X msg 31 39 open \$1; #X obj 31 308 /~ 2; #X obj 31 474 tabwrite~ \$1; #X obj 63 173 b; #X obj 80 243 b; #X msg 53 115 1; #X obj 53 76 b; #X obj 149 326 b; #X msg 63 308 bang; #X msg 80 385 stop; #X msg 151 153 \; \$1 normalize 1; #X obj 80 451 outlet; #X obj 80 428 b; #X obj 149 430 b; #X msg 149 458 \; pd dsp 1; #X obj 149 247 wavinfo; #X floatatom 206 296 10 0 0; #X obj 193 431 print; #X text 136 31 needs wavinfo from ext13; #X text 122 15 e.skogen safeloader; #X obj 53 95 delay 50; #X msg 233 395 \; \$1 const 0; #X connect 0 0 5 0; #X connect 0 0 20 0; #X connect 1 0 22 0; #X connect 2 0 3 0; #X connect 3 0 1 0; #X connect 3 0 26 0; #X connect 4 0 6 0; #X connect 4 1 6 0; #X connect 4 2 9 0; #X connect 5 0 11 0; #X connect 5 0 4 0; #X connect 6 0 7 0; #X connect 8 0 13 0; #X connect 9 0 14 0; #X connect 10 0 8 0; #X connect 10 0 4 0; #X connect 11 0 25 0; #X connect 12 0 2 0; #X connect 13 0 7 0; #X connect 14 0 7 0; #X connect 14 0 17 0; #X connect 17 0 16 0; #X connect 18 0 19 0; #X connect 20 0 12 0; #X connect 20 0 3 1; #X connect 20 0 21 0; #X connect 25 0 10 0; #X connect 25 0 18 0; TESTPATCH: #N canvas 96 257 320 289 12; #X obj 112 76 openpanel; #X obj 112 51 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 45 215 dac~; #X obj 45 149 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X text 63 150 trigger; #X obj 45 172 tabplay~ sample1; #X obj 182 25 table sample1; #X obj 112 102 safeloader sample1; #X obj 45 123 delay 500; #X obj 45 104 b; #X text 16 2 // safe loader for PD; #X connect 0 0 7 0; #X connect 0 0 9 0; #X connect 1 0 0 0; #X connect 3 0 5 0; #X connect 5 0 2 0; #X connect 5 0 2 1; #X connect 8 0 3 0; #X connect 9 0 8 0; ------ http://USFamily.Net/info - Unlimited Internet - From $8.99/mo! ------

latency w/o asio
by Guilherme Carvalho 18 Dec '02

18 Dec '02

Hello list, I'm trying to prepare a concert to show Pd to multimedia students. I just checked what machines I'll have for that and it seems no one has an asio driver for the sound card (all SoundBlasters, I gather). So evidently the latency is up to 200ms or so. Any chance to reduce that without asio? What cards do have asio drivers, and are they easy (cheap) to come by? Or am I missing some evident manipulation of flags and stuff? Thanks in advance, Guilherme

soundfiler and summary information
by marius schebella 18 Dec '02

18 Dec '02

hi, some wave-files which contain a summary information (copyright, comments, blabla). is it possible to skip this data with the soundfiler? now they appear as chunk-data at the end of the loaded sample (10-20 samples). or any other ideas? marius.

PD and paths
by Soren Bovbjerg 18 Dec '02

18 Dec '02

Hi Something has changed regarding PD and paths in version 0.36, and it is not very pleasant. As far as I can see all paths in PD are now relative to the place from where you start PD - and then not. 1) I start PD with a relative command like ./foo/bar/pd/bin/pd -open <filename> With 0.35 filename was relative to the pd binary, now it is relative to where I start it from. This I can live with. 2) I am trying to read a file with msgfile.With version 0.35 the file is placed relative to the pd patch that reads the file. With 0.36 I CANNOT FIND THE FILE :-( ... meaning that relative path does not work. The only way i can find it is if I start PD directly from the /bin directory or to use the absolute path - which is not a good thing. I am not using a 'installed' version of PD but rather an installation placed in my user dir (Linux). What should I change to return this to 0.35 state? /Soeren

Hello list, especially Iohannes, I just noticed that the right inlet of [lister] complains when I send it a float, whereas the left inlet does not. Cheers, Guilherme
