Title: filtering audio with a fractal resonator Post by: claude on November 24, 2016, 12:07:46 AM Sound (in this case simply white noise) goes in one corner, comes out the opposite corner. 10min ambient drone loop.
https://mathr.co.uk/misc/2016-11-22_graphgrow_audio_filter_3.ogv 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.

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...
