Soundcheck reads a physical object's structural health from the sound it makes when tapped: it records the tap, extracts the fundamental frequency, ring time (Q factor), and inharmonicity, and reports whether the object rings like a sound one or thuds like a flawed one. A demo synthesizes a healthy and a cracked ring so you can try it without a microphone, and a reference mode compares a test tap to a known-good one.

Tap it, hear if it's structurally sound. A whole thing rings; a cracked thing thuds — it's how they test train wheels and bells. Read bone, wood, concrete or metal by its resonance. Structures, not diseases.
Tip: no mic? Try the two demos — the tool runs the exact same analysis on a synthesized ring. For a real call, tap a known-good item, hit set as healthy reference, then tap the suspect one.
