Sound tracer

Going back to the most basic expression of painting with sound.
This is meant to be a solution for the randomness of movement of the painting cursor in my other sound painting programs.

I was remembering that we used to do “vibration paintings” in school, holding a pen over a paper while on the bus, trying to transmit the vibrations of the road on the paper. I tried to reproduce this kind of effect by using the music and tracing a point.

A point leaded with audio driven forces. The direction is based on the frequency analysis, the weight is based on the amplitude of the frequencies. The latter version uses one point for the left channel and other for the right channel, it can be viewed as an Anagliph.
The upper one is done using Harrowdown Hill by Thom Yorke The lower one is done using Only if you run by Julian Plenti.
