Description

Implements the algorithm described in IEEE Signal Processing Magazine (11/2009) by Tan and Jiang for tracking fundamental frequency of a harmonic complex based on IIR comb (notch) filtering and the LMS algorithm.

*This is the first version of the algorithm. Author would welcome any feedback & bug reports.

Acknowledgements

This file inspired Harmonic Reconstruction.

MATLAB release MATLAB 7.10 (R2010a)
Other requirements Might need the SP Toolbox if you want to get the coefficients of the comb filter or if you want to use the default initialization routine for the frequency capture range.
