filtering audio with a fractal resonator

[claude]

Sound (in this case simply white noise) goes in one corner, comes out the opposite corner. 10min ambient drone loop.

FFT Filter coefficients are calculated on the GPU, written to a file, and used in Pure-data to process the sound, with a visualisation of the same fractal using Gem for Pd.

Source code here: https://code.mathr.co.uk/graphgrow/tree/HEAD:/c

Currently hard-coded one particular fractal shape controlled by a single parameter, eventually plan to support fully-connected graph-directed iterated function systems of similarities, with a graphical editor.

lol, sounds interesting, where is the (mp3) sound and the video

how to play ogg nowadayz? winamp?

The .ogv is the video with sound - plays right in the browser if you click the link (at least it does so in firefox on Linux).  Otherwise VLC or similar should handle it fine...

vlc did the job with video, thx, dont really understand what is going on but for white noise as input it is not sounding as white noise

woot, it gets on my ears in the middle, very high frequencies very disturbing .... had to quit after 5 minutes
