Audio signals fundamental tracking using Phase-Lock Loops

Antonio José Homsi Goulart
In this seminar we will present Phase-Lock Loops systems, widely used for demodulation of frequency modulated signals. The basic idea behind the technique will be shown, along with recently proposed adaptations for fundamental tracking of audio signals. The efficiency of the system will be confirmed with audio examples, and audio effects based on the fundamental frequency of the input signal will also be discussed.
