[PD-announce] pd 0.53-1test1 released
by Miller Puckette via Pd-announce 13 Dec '22

13 Dec '22

To Pd-announce: Pd version 0.53-1test1 available from http://msp.ucsd.edu/software.htm or (source only) via github: https://github.com/pure-data/pure-data . I've already updated the translations since then, so no worries about that (I think). Otherwise, as always, if anything seems broken you can let the pd list know, or write me personally. I'll plan to finalize pd 0.53-1 later this week. cheers Miller _______________________________________________ Pd-announce mailing list Pd-announce(a)lists.iem.at https://lists.puredata.info/listinfo/pd-announce

is [sigmund~] a "phase vocoder"?
by Alexandre Torres Porres 12 Dec '22

12 Dec '22

Hi, just get things straight and confirmed, for quite a while now I have included [sigmund~] into a "phase vocoder" section of my tutorial. I never check and I'm just guessing it uses what is called "phase vocoder analysis" to find accurate pitches and that can be used in a bank of oscillators and I see that a so called "phase vocoder" is also used for reconstructing signals with an oscillator bank. Who could confirm or deny this? :) Please point me to references if you can. Thanks

[date] and [time] in vanilla, was [random] and seed value
by Dan Wilcox 12 Dec '22

12 Dec '22

Actually, what I meant is that I'd like a date/time object in vanilla in general, not because I need it for a random seed, but because I generate time stamp strings for recordings. > On Dec 12, 2022, at 7:07 AM, pd-list-request(a)lists.iem.at wrote: > > Vanilla could also have something like [date]/[time] one way or another, > but adding it just for the case of managing seeds in [random] seems like a > bad idea to me. -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

Re: [PD] [random] and seed value

Hello all, I don’t think anybody is advocating for this, but I just wanted to be sure that whatever changes are made to [random], the ‘seed’ message capability is maintained. My music very much depends on the ability to control the seed value and get a repeatable ‘random’ sequence. Where I need a truly random seed, I loadbang a [timer], and then have an ‘Init’ button that initializes all of my system. At that point, I use the value from the timer to seed [random].

sonogram abstraction idea with data structures.
by Alexandre Torres Porres 12 Dec '22

12 Dec '22

Hi! I wanted to implement a sonogram analysis like max's spectroscope~ does (see picture) with FFT analysis and data structures. Any ideas? I guess I can [fft~] connected to a [tabsend~] and then have a [bang~] reading the table values for generating the graph, that's my first guess. But I am also now inspired by partialtracer.pd from the data structures tutorial, which uses [sigmund~] and it'd be great if it had a new output mode for raw FFT amplitudes, I am assuming that the 'peaks' output doesn't really work for this, or would it? cheers

sonogram abstraction idea with data structures.
by João Pais 11 Dec '22

Generating and displaying many structs can be very slow, it might not be the most efficient way. Not sure internally if it's better to bang~ a whole table, or find a method to go not so fast. Anyway, when generating structs, it will help if the window where they will be drawn is closed. I think the eargram library had already a sonogram also based on data structures, probably using timbreId. I also did some own improvements to the partial tracer file (for both analysis and synthesis), there were some small bugs/incoherences there: (not sure if this picture will show in the list) > I wanted to implement a sonogram analysis like max's spectroscope~ > does (see picture) with FFT analysis and data structures.

Re: [PD] RaspberryPI GEM
by Dan Wilcox 11 Dec '22

11 Dec '22

As far as I know, nope. GEM requires full OpenGL while RPi supports OpenGL ES only. GEM needs modernization to support ES and maybe Vulkan or something similar at some point but it's a *massive* effort likely. I suggest writing a graphical frontend in a different environment such as OpenFrameworks and communicate between Pd and your app with OSC. > On Dec 11, 2022, at 9:59 PM, pd-list-request(a)lists.iem.at wrote: > > Message: 1 > Date: Thu, 8 Dec 2022 20:46:03 +0100 > From: Jean-Marie Adrien <jm.adrien.mnt(a)gmail.com <mailto:jm.adrien.mnt@gmail.com>> > To: Pd-List <pd-list(a)lists.iem.at <mailto:pd-list@lists.iem.at>> > Subject: [PD] RaspberryPI GEM > Message-ID: <3100A19F-F2F1-4049-AFC0-475AB18A0E9B(a)gmail.com <mailto:3100A19F-F2F1-4049-AFC0-475AB18A0E9B@gmail.com>> > Content-Type: text/plain; charset=us-ascii > > Hello > Anyone knows wether it is feasible nowadays to run GEM on a Raspberry PI and process some 2500 pix_data grey value in real time at 25 fps ? > Thanks ! > :) > JM -------- Dan Wilcox @danomatika <http://twitter.com/danomatika> danomatika.com <http://danomatika.com/> robotcowboy.com <http://robotcowboy.com/>

hidio: can't load library
by Samuel Burt 11 Dec '22

11 Dec '22

Hi, Pd list. I have a student who was trying to use hidio in Pd in Windows. We have 64-bit Pd installed and we installed hidio with Deken, but we can't get the declare object to load it. When we added it to startup items, Pd printed "hidio: can't load library". There was discussion about the stability of hidio back in 2019, though, with it in Deken, I'd assume that it should be in a usable state. Any updates? Sam
