Spectral Terrain — Turn sound into a landscape of light

The carrier of the Serein Signal — or your own voice — decomposed into frequencies sixty times a second and laid out as ridgelines scrolling toward you.

A Fourier transform splits a sound into its frequencies; stacked through time, they rise into a landscape.

Every colour in PHOSPHENE has a tone: its light frequency, forty octaves down. This is what those tones look like when they are allowed to rise.
