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"

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

question regarding -rt flag and Gem lib
by Ivica Ico Bukvic 03 Aug '05

03 Aug '05

Hi all, Now that I've got most of the stuff up-and-running on my fresh Ubuntu install, I've noticed a peculiar behavior: 1) When I start pd *without* -rt flag and with -lib Gem, when using Gem everything is ok in terms of 3D visualization and performance 2) However, when I start pd *with* -rt flag and with -lib Gem, when using Gem every time I try to move a window (Gem-created or the Pd canvas), every 1-2 seconds, the whole X freezes (including mouse) and pd-watchdog kicks in after which the X-unfreezes and I can more window some more until it freezes again for a couple of seconds. Once I release the window, the Gem performs normally. Clicking on the pd or Gem window canvas does not cause any problems (although I did not check with examples that use mouse to move objects inside Gem window). Any ideas why this is happening? 3) Also, while I am asking away, I noticed that when starting pd -rt -jack -lib <anylib> I get connected to jack for a split second and then bumped off after which I need to kill-off pd. Now, if I start with pd with oss with -rt and -lib <anylib> and then select jack in the Media menu, it connects to jack and is all happy. Any ideas how I can make jack more tolerant without bouncing pd? System specs: Laptop m6805 (athlon64 3000+) Ubuntu hoary 5.04 (32-bit) Ati 9600 mobility with latest fglrx 8.14.3 drivers from ATI (tried the same thing with older drivers 8.12 and 8.8 and it behaved the same) Xorg 6.8.2 (no composite nor any other cpu-hogging stuff) I am using pd 38.4-2 from source, Gem 0.90 from source, externs from source, Alsa 1.0.9b from source, and Jack 0.99 from source. Kernel 2.6.10 (vanilla Ubuntu + realtime_lsm module + capabilities) Running without sound behaves the same so Alsa/jack should not be an issue for the first 2 points. I would greatly appreciate your help in these matters. Many thanks! Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

flext externals crash PD
by Jacob Last 01 Aug '05

01 Aug '05

Hi-- I was able to compile both the tutorial examples in flext and my own simple flext externals fine when I was using version 0.4.7...now I'm trying to use 0.5.0 with the new build system (which is great, btw), and everything seems to compile fine, flext is installed. Then I create a package.txt with the minimum info, i.e. just NAME= myexternal SRCS= main.cpp It compiles fine, installs fine, but when I try to create an instance of the object in a PD patch, PD crashes after a delay of about a half second. I don't know how to trace the crash or anything. I'm on OS X 10.3.9, using Hans's installer PD package (Pd-0.38-4-extended-RC1.app). This happens when I try to compile my own externals using the buildsys as well as Thomas's tutorial examples (I created similar package.txt files for those examples). Starting PD from the command line, upon crashing it spits out dyld: ./pd Undefined symbols: _ZN11TableAnyMapD1Ev.eh socket receive error: Connection reset by peer (54) Trace/BPT trap The only warning I get during any of the compile or install procedures is /usr/src/flext/buildsys/mac/gnumake-gcc-ext.inc:40: warning: overriding commands for target `pd-darwin/release-single' /usr/src/flext/buildsys/mac/gnumake-gcc-ext.inc:36: warning: ignoring old commands for target `pd-darwin/release-single' when i do `build.sh pd gcc install` which doesn't seem like an issue. Is there a problem with my use of the new build system or what? I'm stuck. Thanks for the help and all the great work, Jacob Last

flext-based objects and pd 0.39
by Thomas Grill 01 Aug '05

01 Aug '05

Hi all, i realized that the graphical side of attribute-handling is not compatible with pd version 0.39. This means that flext-based objects will display in a strange way or not be visible at all. I'm about to fix this... at the moment the only way to circumvent these problems is to compile flext with the flag -DFLEXT_NOATTREDIT and also rebuild the externals. Thomas
