The input waveform itself is used to generate point normals, which guide the movement of the particles. Low frequencies are tied to the red channel, mid to the green, and high to the blue. The geometry scales along with beat detection. The output is a visualization that is unique to each composition.
In the case that a specific color balance or aesthetic was undesirable, as in during a live performance, custom parameters allow the operator to adjust the sensitivity to each frequency, resulting in a different balance of each color.
