An attempt to use #SuperCollider as a sequencer to synchronize the visuals with the sound.

Best listen with earphone. Or on a stereo player.

Blue triangles and orange circles appear randomly. And fade out again.

A reminiscence of the analog tube radios of my childhood. You could wind a red pointer over the scale to tune the receiver to a different frequency. And you could often hear several radio stations overlapping.

In this animation, vertical bars are constantly moving across the screen. These pointers determine which stations are superimposed.

Best listen with earphone. Or on a stereo player

#radiostation

Blue and yellow stripes are superimposed on a film of the Earth taken from the ISS. The movement of the stripes influences which transmitters can be heard. They also change the stereo panning.

Is it music or is it noise?

Cross-section of an Apollonian Sphere Packing, the notes played correspond to the curvatures of the visible spheres

@noneuclideandreamer This question has been occupying me for some time:

I want to avoid adding a ready-made composition to an animation. Which has no relation to the events in the graphic animation.

I want to avoid generating only noise from the graphic movements or the graphic glitch effects. Without a musical structure.

And i am fascinated by the way Iannis Xenakis composed music.

Apollonian Music!

Full Version: https://youtu.be/MAuyjZuonDQ

We pass through an Apollonian Sphere Packing, seeing its cross-section. Every sphere has a note corresponding to its curvature. It is played when the sphere appears and again when we see it in its full size. Lots of high notes with less deep notes mix to an eerily melodic sound.

A teletypewriter of an LGP-30 machine.

Edward Lorenz worked on differential equations for atmospheric convection. Programming the LGP-30 was done by Ellen Fetter.

That's why I decided that these shapes should move on an Lorenz attractor.

#Clojure #livecoding

Shapes move along a non-periodic path across the plane. In doing so, they reveal the underlying images. A mechanical teletype and the drawing of a flower.

Here's a demo video of my interactive physarum project.

@bleuje I had experimented with the Physarum Transport Network some years ago. The code for these two animations is written in OpenCL.

One example where the Physarum Transport Network "grows on a movie".

And an example where the sound influences the growth of the network.

Another example that was created with Jean. Jean is a live coding software for visuals and sound. This example was recorded without sound and without the #Clojure code. Images in the background by Joseph Constantine Stadler (1780–1812).

During the winter i developed another #livecoding tool. For visuals and for manipulating predefined sounds. The movements in the visuals are able to communicate with Synths in #SuperCollider.

Now i have published the source code and a few examples. The last days i started to write a description. The description is still very incomplete.

You can find out more here:

Moving red an blue shapes. The movement of the shapes has an influence on the sound.

Alright, May Theme is Sound!

Doesn't sound or look so great yet, but the month is young! Here I try out different ... Scales?

Mit diesem Buch habe ich das programmieren von Sounds gelernt. Ich hatte kein Wissen über Notensysteme und was sonst alles noch zur Kompositionstheorie gehört. Die Programmiersprache für #SuperCollider stammt wahrscheinlich von der objektorientiertem Sprache Smalltalk ab.

Ich schreibe die visuellen Animationen in Java oder C++. Sende dann pro Frame oder bei einer “Kollision” ein OSC Paket an SuperCollider. Bei meinem letzten System waren mehr als 90% im Java, 5% in SuperCollider (und 5% LiveCoding in Clojure) programmiert. Ich will dies noch beschreiben und dann als open source veröffentlichen.

@noneuclideandreamer Beispiel: das 3 Körperproblem.
Vorbedingung: die Positionen können in Echtzeit berechnet werden.
Pro Frame werden die Geschwindigkeiten an SuperCollider gesendet und verändern die Tonhöhe (Oberschwingung ..) eines Soundgenerators.
Pro beinahe Kollision wird ein kurzer zusätzlicher Sound gestartet.

Das Stichwort ist Sonification.

@noneuclideandreamer Hier habe ich angefangen zu beschreiben wie ich #Java und #SuperCollider kopple. Das "Jean live coding System" ist damit noch nicht erklärt. Aber die Links zeigen wie die Visualisierung Open Sound Control Telegramme sendet. Und wie die passenden Empfänger in SuperCollider aussehen. Weiter oben im Text ist auch meine Motivation notiert warum ich die audio-visuelle Kopplung gerade so gelöst habe.

@noneuclideandreamer Mit dem konfigurieren der Audio Signale habe ich viel Zeit verbraucht und nicht das Gewünschte erreicht. Es gibt im Debian / Linux unterschiedliche Transportmechanismen, alsa, jack, pipewire das jack emuliert.... MIDI nur exklusive von einem genutzt, Aber digitale Sounds Samples können kombiniert werden. Ich habe bei eigentlich einfachen Dingen aufgegeben.

The picture as a whole looks chaotic. And is in candy colors.

But if you look at the details in the image, parts of the original photo are still recognizable. A rose, a cushion cover, the number 2022.

#databending

The entire picture. Horizontal stripes in rainbow colors.
