How does Mathematica use
AudioLocalMeasurements to compute the fundamental frequency?
Is there any formula? I can't seem to find what method Mathematica makes use of.
Here is an example.
You can use Cepstrum,Wiki says
It was originally invented for characterizing the seismic echoes resulting from earthquakes and bomb explosions. It has also been used to determine the fundamental frequency of human speech and to analyze radar signal returns.
