Acoustic Trail 3D

Your audio mapped to its own natural coordinate space. Spectral centroid (brightness) → X. Treble ratio → Y. Bass energy → Z. The trail you leave is the acoustic fingerprint of your performance.

A single clean pitch traces a vertical column. A dense chord spreads wide. Bass notes pull toward the Z wall. Drag to rotate. Inspired by SoundPlot (arxiv 2601.12752).
