Pitch detection

This project was part of bachelor thesis created in 2018/2019 at CTU FEE with RNDr. Ondřej Žára as the advisor. The main goal of this bachelor thesis is to design and implement a mobile web application that will analyze the audio signal in real time. This analysis is then used as a guitar tuner. The application is based on solving the problem of pitch detection by two methods -- autocorrelation and fast Fourier transform. The final version of this application uses both of these methods to recognize the fundamental frequency.
