Radial Sound Equalizer

A circular spectrum analyzer arranges glowing bars around a ring, each one standing in for a frequency band the way a real audio equalizer splits sound into low, mid, and high bands. In a real spectrum analyzer, each bar's height reflects the amplitude (loudness) measured in that band at that instant, so a wall of bass produces tall bars on one side while shimmering highs animate another. Here the audio is simulated with layered sine waves and a shared low-frequency "beat" envelope, so all bars breathe together on the beat while still flickering independently like real frequency bins. Watch how bar height pulses in time with the beat light at the center, and how color sweeps from cool blue at low amplitude through green and yellow up to hot red at peak amplitude, mimicking the way spectrum displays color-code loudness. The whole ring also slowly rotates and reflects off the mirrored floor, so the visualization reads as much like a stage light show as a technical measurement.
