This was the product of initial formal explorations of sound early in the development of this project. These explorations manifested as a grid of 16 ellipses that represend 16 bands of frequency ranging ~1250 Hz each. These frequency bands are arranged left-to-right in a grid from low frequency to high frequency. The average amplitude of each of these frequency bands is then visualized by the size of an ellipse with a white stroke. As time passes, more ellipses overlay to form the density of frequencies present in the location across the duration of the recording.
