What are the techniques for pitch identification?

Among the various pitch detection algorithms, the following methods can be selected: modified autocorrelation method (AUTOC),² cepstrum method, multiband summary correlogram (MBSC),⁶ BaNa,⁷ YIN,⁴ yet another algorithm for pitch tracking (YAAPT),⁵ average magnitude difference function (AMDF),² SWIPE,²⁹ and pitch ...

What is pitch analysis?

What is it? Multi-pitch analysis is the task of analyzing the pitch content (fundamental frequencies, F0s) of polyphonic audio (e.g. polyphonic music, multi-talker speech, multi-bird songs). It includes estimating the frequency and number of pitches at each time frame, and organizing the pitches according sources.
