Panel Analysis

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.
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.
