Audio Analysis

Each song is broken into three frequency bands every frame using a Fast Fourier Transform (FFT). Bass (0–250 Hz), mids (250–4000 Hz), and highs (4000 Hz+) are tracked separately so each layer of sound can drive something different visually.

What Drives What

• Bass Shape size — kicks and low end make the wireframe expand outward via spring physics
• Mids Rotation speed — vocals and guitars spin the shape faster in choruses
• Highs Strand gap — hi-hats and cymbals spread the edge strands apart, then pull them tight in silence
• Beats Pulse — every detected beat kicks the rotation and briefly brightens the shape
• Energy Trail length — loud moments produce short crisp lines; quiet moments leave longer dreamy trails

The Shapes

20 geometric wireframes cycle throughout each song — from sparse open forms like a Tetrahedron or Axis Star, up through dense complex ones like a Torus or Great Icosahedron, then back to open again. Each edge is drawn as two flowing parallel strands with a shared sine wave, so they breathe and ripple together rather than sitting still.

Color Palettes

• Whiskey Warm amber and gold with deep sapphire blue — built for Tennessee Whiskey
• Sure Periwinkle and lavender shifting into soft rose — wistful and uncertain
• Prophecy Deep violet burning to fiery crimson and gold — mystical and intense
• Folding Ocean teal folding into warm coral — two colors weaving like fabric
• Rainbow Full spectrum shifting with the music — fast and energetic
