What is Yin algorithm?

The Yin algorithm was developed by Alain de Cheveigné of IRCAM-CNRS and Hideki Kawahara of Wakayama University. It allows for real-time fundamental frequency estimation. It features a very low error rate and few tuning parameters.

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.

How do you find the pitch of audio in Python?

pitch 0.0. 6

This is a package to find pitch of an audio signal ie. wav file. Use the function by giving the input argument as the name of the wav file (type==str). Function returns the value of the pitch of the audio.
