Detecting pitch automatically - The intuition behind the YIN pitch detection algorithm
Показать описание
Sound is messy and difficult to deal with, yet with some simple techniques, we are able to write a short program which deals well with pitch detection in many real cases of monophonic audio. This video covers the main steps used in the YIN pitch detection algorithm [1] and visualizes the underlying concepts with various animations.

Corrections:
- The 2 samples played at 0:40 are not actually the same pitch, but 1 octave apart, specifically 110 Hz and 220 Hz respectively.
