Hello folks; if you would like to support my work, it would be great if you could do that through my Liberapay: https://liberapay.com/sciss/donate - thank you!

#Almat news - many materials have now been published on the continuous exposition: https://www.researchcatalogue.net/view/381565/381566

Notably, you will find talk videos for 'Simulation and Computer Experimentation in Music and Sound Art' at Orpheus Ghent, and 'Algorithmic Spaces' at ZKM Karlsruhe.

Happy browsing!

About this account

I'm a sound and digital artist, interested in installation and intermedia, improvisation and electronic/electroacoustic music. I develop a bunch of open source software.

I keep only one account, so the toots are a mix of sound/art focused things, random thoughts, and few rants (CW'd, and you don't need to share my opinion). I'm friendly/respectful 🍍 + aim to keep an open mind.

Account is locked (allow time to review), because I don't want bots and nazis to follow me. Thx 🌈

"#Myanmar troops' sexual violence against Rohingya shows 'genocidal intent' - U.N. report"

https://www.euronews.com/2019/08/22/myanmar-troops-sexual-violence-against-rohingya-shows-genocidal-intent-un-report

Stand with #Rohingya refugees.

"Since the events take place on both sides of the border between Austria and Slovenia, we would like to remind you to carry your passport."

Do you remember there was a thing called #Schengen agreement? 😠

Scala-Python interop, might come very handy: https://scalapy.dev/ #ScalaPy #Scala

I transcribed some notes on memory (allegedly) and added a soundfile-in-progress

Made it from #Debian Stretch to #Buster; here are a few things I had to fix afterwards: http://sciss.github.io/debian-stretch-to-buster/

#Mellite v2.38.1 is out - https://archive.org/details/Mellite - including the Negatum genetic programming object. I also published a new tutorial for that object: https://peertube.social/videos/watch/0ae57dac-5f7d-4f0b-87e8-7d49250bb1da

My colleague confirmed this impression; seems to require closed headphones. My theory is that we "hear" a spectrally complementary function, for example notches when there where strong partials, similar to how we see negative afterimages when we look at a static image for a while and then move the eyes to something else.

There is a reference from German psycho-acoustician Zwicker about an "acoustical aftertone", describes as sine components after prolonged hearing of a notched noise.

Another interesting genetically programmed sound: https://open.audio/library/tracks/42839/

code: https://framabin.org/p/?7a34cb12a5891fe4#a5pFiLaOtV4EJgoFqeI01k1k88WhWMtQf202LLdMv+M=

scalacollider-code for that sound:

RandSeed.ir
val freq0 = Seq(1.0, 1.02).map(_ * 8.824352)
val freq2 = Seq(1.0, 0.994).map(_ * 7860.8604)
val xi = LFSaw.ar(freq = freq0, iphase = 0.0)
val freq_0 = xi clip2 0.011223611
val lFDNoise3 = LFDNoise3.ar(freq_0)
val cuspN = CuspN.ar(freq = freq2, a = 1.0, b = 0.0, xi = xi)
val mix = Mix(lFDNoise3, cuspN))
val sig = Limiter.ar(LeakDC.ar(mix.clip2(1.0)) * 0.5)
Out.ar(0, Pan2.ar(sig))

There is a peculiar phenomenon with "strict" repetitive electronic sounds that I noticed a few times. When listening to these sounds for prolonged durations (a minute or two suffice) via headphones, then turning them off, all your "natural" acoustic environment has a strange modulation to it. E.g. with the following sound, the acoustic "after image" I have is some "bubbly" or "fft-ish" modulation of my environment. Guess it's a neural-physiological thing:

Did you know that butterflies can swarm? I certainly didn't before today, when I saw a swarm of nine or so Pieridae dancing around for several minutes as if tied together by elastic invisible straps. That was just incredibly beautiful. 🦋

After years (?) of silence, there is another #SuperCollider symposium next year at Wesleyan: http://supercollider.wesleyan.edu/

The info is that James McCartney will be talking about his new language project which "draws on ideas from APL", code is compiled and stored in database (why that sounds familiar LOL?), but no pre-compiled UGens but live DSP code. Exciting!

Back to working with the genetic synth-def programming in #Negatum ; I will try to integrate that soon into mainline Mellite. Now trying to automatically reduce the redundant graphs (replace constants, replace duplicate UGen signals). Here is a nice one:

(should I use mp3 directly now in mastodon or stick to funkwhale?)

I learned a word last week: Petrichor - it's the amazing type of smell you get when the streets are dusty and it just begins to rain

Having a great time at #xCoAx in Milano.

Yesterday also came the great news that our project 'Algorithmic Segments' will be supported by the cultural office of #Graz for 2020, which will run up to and including the joint Almat + xCoAx conferences next year, building an exhibition distributed across the city.

Calls will be prepared for autumn this year.

Something weird happened to the high pass filter; I guess it didn't stay in sync with the frequency shifter?
