ReadonlyabovedB the peak reads above the search band's own median — the module doc's threshold, kept on the reading so a caller can rank candidates, not just filter them.
ReadonlyhzReadonlyqEstimated Q from the half-power (−3 dB re peak) bandwidth either side of the peak bin,
linearly interpolated between bins. Narrower than one bin's own half-power span reads as
the narrowest this accumulation can resolve, hz / (2 * binHz) — never a divide-by-zero.
One candidate peak in one position's own curve.
