acid
by Chris McCormick 14 Aug '14

14 Aug '14

Hi, Another question in a very general vein. I asked this on the Csound list a while back (when i was using csound) with good results. I'm trying to produce an acidy type sound (eg 303) and having trouble as my current saw-tooth-through-a-vcf just sounds pretty wimpy. Any ideas on how to fatten it up a bit? I'm not looking for a perfect reproduction of the 303 sound, just a nice acid sound. Hints? Tips? Is there some place where people post interesting Pd patches they've created for others to download at try out? Should there be?

display waveform in GEM
by derek holzer 27 Feb '06

27 Feb '06

Following an idea from Gerhard Daurer, I'd like to look into displaying the waveform of an audiofile in a Gemwin. Gerhard sent me a prototype of a very cool patch combining my Particle Chamber with PMPD and GEM, which uses physical modelling to visually control the granulation of a soundfile. (And I hope he posts this same prototype here soon!) In his version, he has only a set number of audiofiles to choose from, so he simply loads a JPG of the waveform into the Gemwin. However, I'd like to be able to load any wav file into this and get some visual feedback (i.e. be able to see the peaks). This would be a one-time operation, and not something that would be changing in realtime (except maybe a zoom in and out), however I would like that displaying the peaks doesn't interrupt audio processing (as drawing a table would). I'd like to use GEM for this so that the various grains could be graphically represented on top of the waveform. I'm open for PDP implementations, but I don't really consider PDP cross-platform so I'd rather stick with GEM. Any Gemheads out there have an idea of how to go about this? best, d. -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 82: "Honor thy error as a hidden intention"

Playing with the new data structure features
by Frank Barknecht 17 Dec '05

17 Dec '05

Hallo, hm, I really like the additional features of data structures. The scaling, although a bit awkward to use or to get into, gives some nice new possibilities. Some are illustrated in attached patch. I think, one major advantage now is, that ranges can be restricted, something that came up here as a feature wish a couple of times. It could be nice to also include this for [drawnumber], which currently doesn't work. Also thanks to the scaling it now is possible to have "inverted" ranges, which as in attached slider example often is more natural to use. Switchable visibility can be used for nice effects, too, and might be useful in conjunction with the new selection feature as well. Visibility switching however doesn't work correctly with [drawnumber] yet, which can be demonstrated by adding a "-v vis" to the [drawnumber ...] instruction in the slider template: Numbers don't get deleted correctly, when their visibility is switched off. I didn't yet play a lot with the selection feature yet, apart from looking through the help and example patches. It also looks immensly useful, because it provides a kind of callback on editing operations through the pointer sent by the [struct]. However the current mechanism doesn't allow one thing, that could be useful as well: If I change the value of some graph, while I'm not in edit mode, there still is no direct feedback. OTOH when I'm in edit mode, I can select an object and get this feedback, but I cannot change its data fields unless I leave edit mode again. With all this, I see that I can make a lot of cool enhancements to my msd-editor, which unfortunatly have to wait another week. ;) Ciao -- Frank Barknecht _ ______footils.org__ _ __latest track: "plak" @ http://footils.org/cms/show/44

feature extraction
by Jacob Last 28 Nov '05

28 Nov '05

Hi all-- I'm currently working on a project for controlling my granular synth patch using a control stream derived from various feature extractions from an input signal (soundfile or live). Currently what I'm working with is the spectral centroid, which I've implemented as a PD patch. I'm wonding if people have other ideas for perceptual features that can be reliably extracted from an audio stream using the FFT or otherwise. The input is not necessarily pitched (might eventually want to analyze its own granular output as well, in addition to noisy and unpitched sounds) so I'm not that interested in pitch tracking, etc. rather more high level sonic features. For example, how might I detect a period of sharp attacks on a wind instrument? Maybe by using some sort of peak threshold with the spectral centroid? "Smoothness" of a sound? Continuum of pitched to unpitched? Etc. Also if there are any PD implementations (abstractions or externals) of this sort of stuff please inform me; I haven't found anything as of yet. I'd very much appreciate any input! Best, Jacob

[Gem] how to optimize alphablending?
by Roman Haefeli 10 Sep '05

10 Sep '05

hi i attached a patch, that is used to 'alphablend' from one to another picture. it is working though, but the cpu-load raises to 100% and it looks quite 'ruckelig' (not constantly flowing). i tried it on different machines with the same result. then i tried it with a better gfx-card, that supports opengl (Quadro FX 330), on a P4 2.66GHz (winxp). it looks better, but my patch still uses 100% cpu. i'm quite a gem-newbie and don't know much about opengl, but i assume that my patch is not optimized and there is still much calculated by cpu instead of gpu. last week i saw a screensaver-slideshow on an old ibook, that looked very nice. this let me hope there is still a chance, that i can realize the same with Gem on hardware that is up-to-date. thanks for any help roman

gem - pix_kaleidoscope
by demidelirium＠gmail.com 02 Sep '05

02 Sep '05

can anyone shed light on why i'm unable to create a pix_kaleidoscope object? environment is winxp (sp2) pd 0.37, gem 0.90.1 i just get a "couldn't create" message at the command prompt, and of course a box with no ins and outs i know the kaleidoscope was ported, is it likely that 0.90.1 doesn't include it?

Re: [PD] elucidation on syncing r~'s
by Matthias Blau 02 Sep '05

02 Sep '05

Thanks Mathieu, however, it is not that easy: no loops in my patches (I wouldn't have been able to substitute them by patch cords would I), but nonetheless delays between r~s. >That information is all before your eyes. Just follow your patch >backwards >to see where the signal you are send~ing is coming from. If the object >you're sending to is _also_ a place where the signal came from (i mean >any >signal contributing to what you're send~ing), then you get a >chicken-and-egg dependency. Pd then solves that problem by delaying the >sent signal so that it only has an impact at the next "instant" in the >future, that is, one block away. --Matthias

Dear PD-community! PDradio is a self-regulating internet radio station for the PD-community (and is of course build with PD ;). Upload your PD-related music, vote for songs, listen to the automatic radio moderator ... The link: http://pdradio.iem.at Please feel free to upload your music and participate! We hope you have fun with it, LG Winfried+Georg ------------------------------------------------ PDradio: PD Webradio is a self-regulating internet radio station for the PD-community. Registered users can upload PD-related music and share them with the community. Because we didn't want to compile the radio program all the time we build an automatic radio DJ. All user can vote for a song they would like to hear and the DJ will generate a playlist according to all votes. Additionally there is an automatic radio moderator, who speaks a little bit about the songs (metadata which can be uploaded together with the music) and maybe is joking somtimes ... PD-webradio is running on a Linux Server with Zope/Plone. The audio streaming, speech synthesis, radio-moderator, DJ, ... is implemented in PD and Python for the communication to plone. If you want to listen to the PDradio, vote for songs or you have music related to PD and want to share it - follow the link: http://pdradio.iem.at ------------------------------------------------
