In continuity with my interest in Audio Painings, i kept thinking on ways to create different tools to draw based on audio information. After the colored waveform, my next idea was to keep using frecuency information as source for color hue, but i was looking for a more organic result.
As a first try, I used filled circles around a point, assigning different frequencies to each and varying their size by the frequency magnitude at a given time. The position of this ‘brush’ changes by using a random walker driven by the sound’s level and the difference between the stereo channels.
After, I changed the circles for blended paint spots, inpired by Pollock and his randomness, and added support for capturing the sequence of painting with sync with the music.
As of now, this app has control over the step size of the brush, it’s size, and the spacing of the shapes around the center of the brush.
