Ok I see the instrument *can* indeed be improved a lot, first of all detecting
only positive or negative zero crossings, eventually detect different notable
points (maxima, minima, +&- zero crossings) and weight the results, then get
the fractional part with some kind of movable mean. Also, discard too short
periods based on a first estimated pitch.
Any other idea? ... I´ll improve the tracker.
