modulating PWM drone with echoed high pitched things and various fast kicks (with a bit of DC offset, sorry)

source code composed in https://mathr.co.uk/barry/v2/ , rendered to WAV using barry command line version.

I released #zoomasm version 1.0 "felicitats" yesterday. It's a tool for assembling #fractal #zoom #animation #video from exponential strip keyframes with RGB and/or raw iteration data in EXR format - the colouring is controlled by an #OpenGL #GLSL #fragment #shader snippet with a few presets included (or write your own).

(However, the only software I know of that can export keyframes for input to zoomasm, is #kf 2.15 branch which is not yet released... so getting that done is my new focus.)

I will be #LiveCoding in the #C programming language from 6pm BST (1.5 hours from now), with Q&A afterwards (assuming mic works).

Managed to get a lightly modified #Etherpad working with my #Barry interpreter for #collaborative #LiveCoding of #PostFix #ByteBeat #audio.

It's implemented as a bit of hack modifying the core template pad.html at present, but it should be possible to port it to a standalone Etherpad plugin - I was just fighting with npm and node and require() and things I don't understand at all so took an easier way out.

Firefox's "strict" content blocking mode breaks it. Not sure why.

Added EXR import to my #MultifractalSpectrum calculator. Hacked an option into #Fractorium command line renderer to output raw histogram data to EXR. Ran a batch process to render and analyze some of the examples that come with Fractorium (in its Data/Bench directory).

I'm listening to @netzzz on http://apo33.org:8000/filiason and it's very nice

Ported my #FractalFlame renderer to #OpenCL. Even on #GPU the #DensityEstimation is way too slow to be useful, it's quicker to get the same visual quality by plotting a zillion points.

The attached has around 8k samples per pixel, taking around 1min/frame (1 hour total). 256k subframes for motion blur, each being a single path of 16k iterations. Only plain simple #MoebiusTransformation stuff without xaos control..

Almost time for the start of the #EulerRoom #Equinox #TOPLAP #LiveCoding #Algorave #Streaming #Event
