A circular grid of neon bars pulses to a procedurally generated multi-band synthetic waveform. Each bar samples one of 64 synthetic frequency bands built from layered sine oscillators plus a slow envelope and a periodic beat pulse, mimicking how a real FFT-driven visualizer reacts to bass drops. Bar heights are smoothed with frame-rate independent exponential easing rather than snapping directly to the raw signal, and emissive intensity tracks the same signal so louder bands glow brighter. The whole ring grid also slowly rotates for a club-visualizer feel.
