Humming Hz Meter

Measures your humming pitch (fundamental frequency) and guides you to a target (default 130 Hz).

Target Hz: Tolerance ±Hz:

— Hz

Tap Start and hum.

Confidence: —

Closeness to target

Tip: steady hum + consistent breath gives the most stable reading.

Notes:

This measures pitch (Hz), not volume. If you want volume too, we can add a dB meter.
Background noise can confuse detection — hum close to the mic in a quiet room.
Some voices may find 130 Hz low/high; you can adjust target anytime.
