Bayesian Pitch Tracking Using Harmonic model

A fast pitch tracking algorithm using the harmonic model.

The article for this work is available in PUBLISHED, PREPRINT

How to run

This project contains both the MATLAB and CPP code

For the MATLAB code:

Run run_white_example.m (white Gaussian noise) or run_colored_example.m (factory noise) in MATLAB in the BF0NLS_MATLAB folder

Run main.m in MATLAB in the BF0NLS_realtimeDemo_MATLAB folder

Examples

Figure 1: Pitch estimates for speech signals under 0 dB white Gaussian noise (Running time on my laptop is around 2.6 s).

Figure 2: Pitch estimates for speech signals under 0 dB factory noise (Running time on my laptop is around 9.3 s, and prewhitening is used).

Figure 3: Pitch estimates for music signals (vibrato flute sound) under 0 dB white Gaussian noise (Running time on my laptop is around 32.2 s).
