How does pitch detection work?

Perhaps the most basic algorithm that can be considered for pitch detection is the zero crossing method. As the name implies, this technique works by analyzing an audio signal in the time domain and counting the number of times the amplitude of the wave changes from a positive to a negative value.

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.
