Ampley · MIC monitor

Detect and learn only. Uses your phone mic once (Safari OK). Flags metal-shaped sound wave peaks and rapid HF crossing / sonic-shake signature. Hearing nothing is fine. No RF emit. Not a weapon.

Hypersonic (Lawrence): high frequency crossing in rapid change enough to create sonic-kind shaking.

Metal-shaped sound wave peak

Metal flag: sudden rise in overall energy (sharp attack) plus strong mid/high-frequency share vs bass. Sonic-shake flag: high-frequency band energy that changes rapidly (delta over a short window) — rapid HF crossing.
