- Do a series of short FFTs with a raised cosine window and L/2 overlap,
then use the evolution of the phase to find the exact frequency.
- One short FFT to find approximate frequency, then start a PLL
to track the signal.
Both can be very precise if implemented correctly.
Lascia la spina, cogli la rosa.
