Detailed Description¶

Allocate with dp_tonemeas_create(). nfft = next_pow_two(n * MEASURE_PAD) is the zero-padded transform length; enbw is the window's equivalent-noise bandwidth (bins); lobe_bins is the main-lobe half-width L over which a component's power is integrated; spur_guard_bins (>= L) is the wider fundamental keep-out used by the worst-spur search so the fundamental's own sidelobes are never reported as a spur.
