About Aurora Flow
How it works
Particles are arranged along vertical curtain strips using a noise-based displacement field. The noise field is seeded deterministically and its parameters are modulated by audio features: bass energy drives large-scale displacement amplitude, mid energy controls the noise frequency (ripple density), and high energy adds a secondary high-frequency noise layer for shimmer. Color is computed per-particle using a physically-inspired model where altitude maps to hue (green at low, purple at high), with intensity modulated by local audio energy. The curtains are rendered as alpha-blended point sprites with soft edges.

MusicMind Engine
Tension Analysis (L4) drives curtain sway intensity from harmonic tension, Key Color Mapping (L6) shifts aurora hues based on detected musical key, and Narrative Arc (L7) paces curtain motion through the song's dramatic structure.

Aurora Flow's color palette is derived from the Scriabin-inspired key-color mapping — the dominant color shifts based on the detected musical key.
