Visualizer was an exercise to reflect power spectral variations in ambient sound, speech or music to visual interpretation. Incoming audio is sliced into three, slightly overlapping, spectral windows. Composite power measured in each window is converted, in real-time, to point light source location on a grid defined by counter-opposing spiral and rectilinear coordinate systems.
High and medium frequency spectral power levels activate the visual frame clockwise or counter-clockwise, respectively. Low frequency bass notes pierce the visual field via orthogonal framing.
