This interactive projector work produces particles when participants make noise. The particles and their sizes are determined by the frequencies heard in music, from people when they sing, speak, grunt, scream, clap or any other noise.
Built in Processing using the Minim sound library by Damien De Fede, this software uses a Fast Fourier Transform algorithm to determine frequencies heard through microphones. The result of this analysis returns frequency information split into three bandwidths then averaged. The averages then control the three different particle types: bubbles, cubes and voronoi cells.
The attached video shows the interaction between music and the particles generated.
