loudness, brightness, harmonic (chroma), and rhythmic-attack data, and exports it as a
single file, a data mirror of the recording that can be read rather than played back.

Low frequencies (below middle C) become soft glowing colour washes; higher frequencies
become soft-edged pointillist light, scattered like stars. Hue follows a note-colour
association (purples toward B, reds toward C), saturation and density track loudness,
and stereo pan nudges elements left or right. Position and colour come entirely from
the song's own data, the same song always paints the same sky.
