Re: [PD] [PD-dev] Why not use portaudio per default?

You can build portaudio with just OSS resp. MMIO support and get the same result :-) (Not to mention that on Windows there are much better native options, like WASAPI.)

I guess the pd list address got accidentally left out? Putting it back...

The keyboard GUI was the first in my library but someone else had coded it, I developed on it. Most of my GUIs are pretty simple and I still have to learn how to properly code properties windows. I also design GUIs with data structures because I still find it very hard to code GUIs myself, for instance, [slider2d], [multislider] and many others (most of my GUIs are actually just abstractions). So, if anyone knows of a good tutorial on how to write GUIs in Pd, I'd love that too, hahahaha cheers

[PD-announce] Click Tracker - Version 2.2 is out!
by João Pais CT 21 Jan '22

21 Jan '22

Dear List, Version 2.2 of the Click Tracker is out. The new features are tempi with different base units, Audio Status window with output control in standalone version, and improvements in Max GUI feedback. This version was generously supported by Stefan Prins (http://www.stefanprins.be/) As in the previous version, you can use in any of the following ways: - as an android app (https://bit.ly/click-tracker-mob or https://bit.ly/clicktracker-playstore) - as a closed desktop app in windows (http://bit.ly/ClickTracker2-2win) or apple (http://bit.ly/ClickTracker2-2Apple) Due to Apple's recent security settings, you'll need to allow the Pd and other externals to run on your system. WARNING: M1 users will need to run the program with Rosetta. - as the traditional Pure Data patch (http://bit.ly/clicktrackerv2-2) - as a Max/MSP patch in windows (http://bit.ly/ClickTracker2-2MaxWin) or apple (http://bit.ly/ClickTracker2-2MaxApple) For more information, refer to the Click Tracker's website at http://j.mp/click-tracker. You can also visit the Click Tracker on facebook - http://j.mp/clicktrackerfb, or check out the click track library in http://jmmmp.github.io/clicktracker/index-library.

I have a vanilla spectroscope abstraction: g_spectroscope. It's pretty simple and good enough for showing a graph, not really for scientific precision. There are also update & dimension controls plus you can turn it off to save CPU. https://github.com/danomatika/rc-patches/tree/master/rc <https://github.com/danomatika/rc-patches/tree/master/rc> > On Jan 20, 2022, at 6:01 PM, pd-list-request(a)lists.iem.at wrote: > > Date: Thu, 20 Jan 2022 16:46:02 +0000 > From: Pierre Alexandre Tremblay <tremblap(a)gmail.com <mailto:tremblap@gmail.com>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] A strange question (yet again) > Message-ID: <12F096C2-A42D-42BA-8146-B784978F6464(a)gmail.com <mailto:12F096C2-A42D-42BA-8146-B784978F6464@gmail.com>> > Content-Type: text/plain; charset="utf-8" > > Sorry again for my obsessions with pd-vanilla which makes everything harder - this one might be impossible! > > I?m trying to draw a spectrogram in pd-vanilla to match our waveform visualisation options in FluCoMa for Max and SuperCollider.

[PD-announce] PhD Assistantship at Virginia Tech focusing on research and development of the pd-l2ork platform
by Ico Bukvic 17 Jan '22

17 Jan '22

Please pardon cross-posting, The following announcement may be of particular interest to graduate students seeking PhD oppportunities. Please share widely, as appropriate. Virginia Tech Human-Centered Design (HCD), a unique individualized interdisciplinary PhD program, in collaboration with the Linux Laptop Orchestra (L2Ork) has a new fully funded graduate research assistantship available. Supported as part of a grant from the Office of Naval Research, the assistantship is looking for a graduate PhD-level student who will be fully funded for up to 4 years (contingent on adequate progress) to work on a project that combines knowledge in sound and music with that of cybersecurity and K-12 education. Desired expertise includes: - Solid C and JS programming skills - Familiarity with emscripten and building Web apps - Solid knowledge of acoustics, psychoacoustics, and of digital signal processing using visual dataflow programming languages, such as Pd-L2Ork/Pd or Max While student will be required to work on the funded project, they will also have an opportunity to develop facets of the said project into their own dissertation, as well as explore their own unique research trajectories. Students who may not possess all the desired expertise but only a subset are also welcome to inquire and apply. Before applying, students are strongly encouraged to contact me to ensure they may have the right skillset. Virginia Tech offers top tier research facilities in areas of spatial sound, immersion, and telematics, including a $30M Moss Arts Center and the Institute for Creativity, Arts, and Technology's Cube with its 140+ loudspeaker array, multi-projection surfaces, and a high resolution motion capture system. The said space is supported by a constellation of other labs, including the Perform studio with its 24.4 Genelec and Mocap system, DISIS with its 24.2 system, Create Studio with access to cutting edge fabrication tools, and many more. Most of the audio facilities on campus are networked using the Dante protocol.

Trouble with updating number boxes, sliders, arrays on RPi - looking for a replacement to display an array
by Ingo 17 Jan '22

17 Jan '22

Hi, I had some trouble with number boxes, sliders, etc. again. This time on the Raspberry Pi. With the exact same programming they work fine on a i386 Intel computer (Debian) but do not update graphically on the Rasperry Pi 4 with Raspbian. Must be a TCL/TK issue thinking that all these objects are hidden . . . After weeks of trying to find a solution I gave up and replaced several hundred of parameter editors with numbers or sliders in the background (working) and a canvases on top for sidplaying the actual values. Others got replaced with dropdown menus using pmenu. This works quite well and looks a lot better. The only thing that I'm missing is some graphes of curves that I need to display. Unfortunately the arrays do not get updated graphically either on the RPi. Does anyone know of a way or an external that can be used for displaying curves besides arrays? Something ike this: Thank you! Ingo

JACK and blocksize
by Roman Haefeli 17 Jan '22

17 Jan '22

Hey all Using callbacks is certainly interesting for low-latency applications. I noticed that JACK allows blocksizes below 64, namely 32 and 16. However, those can only be used with callbacks disabled which means having to use an additional buffer again. I wonder if the blocksize of 64 is deeply baked into Pd or if it could theoretically be made configurable. There might be other reasons why smaller (or larger) blocksizes would be interesting, but low-latency seems to be one. I found the '-blocksize' flag, but it seems it only sets the blocksize for audio I/O and doesn't affect Pd's internal blocksize (and doesn't have any effect at all when running with -jack). Roman

How latency works in cloned abstraction? (dsp graph order)
by José de Abreu 15 Jan '22

15 Jan '22

Hello list, I have a curiosity, let's say that I want to clone an abstraction that reroutes signals between the cloned instances. We learn that if a send~ is sorted before the corresponding receive~ we get no latency, but if the receive~ is sorted before, it reads from the previous block, so we get by default 64 samples of latency But how does this order work in the case of cloned abstractions? the abstractions with a bigger or smaller "index" would be sorted accordingly (from 0 to n), or is it somewhat random? so if for example abstraction 0 sends to 1, that sends to 2, it would be 0 latency, but the opposite would be 128 samples?
