Golden Panel Audio Evaluator
Golden rectangle (height H, width H/φ). Asymmetric fifths cuts (2/5 or 3/5). 1536 unique layouts: 4 (Step‑1) × 4! (Step‑2 permutation across quadrants) × 4 (choose Step‑1 quadrant for “5th”) × 4 (Step‑3 cut).
Physics: thin‑plate bending / membrane / mixed, boundary selector (including two‑string suspension), tonal masses (20–25% total), 5–20kHz sweep, listener SPL or point “mic” FRF.

Line colors: L1 blackL2 blueL3 red.
Step‑3 applies only to the largest Level‑2 rectangle inside the selected Step‑1 quadrant.
Step‑3 applies only to the largest Level‑2 rectangle inside the selected Step‑1 quadrant.
Tonal mass is split equally across 5 points: 4×(Level‑2 intersections) + 1×(Level‑3 intersection).
Damping + rigid modes (advanced)
For free-free / strings, expect near‑zero “rigid” mode(s). Keeping them avoids silently deleting low-frequency behavior.
Compare uses the same physics settings as the Physics tab. Curves are overlaid on the main plot.
Offline compute (export → run Python → import results)
Use this when high Ny crashes the browser. Export a settings JSON, run the Python batch solver, then load the results here for instant ranking/compare.
Use loaded offline results for ranking / compare / main plot
Ranking uses the currently selected output type (SPL or mic) and the same sweep settings.
