Any mechanic, any phone. I record five seconds of the machine's sound — raw 48-kilohertz audio. On-device signal processing finds the shaft frequency and reads the RPM automatically."Now the math: I band-pass the resonance band, take the Hilbert envelope, and FFT it. Bearing physics says each defect — outer race, inner race, ball, cage — impacts at a frequency you can compute from the geometry. I match spectral peaks against those, with harmonic and significance gates so ambient noise never fakes a fault."And through the Live API, he just talks to it — and shows it the machine. Which bolt? It sees it.
