Abstract : HRHATRAC combines the last improvements regarding the fast subspace tracking algorithms with a gradient update for adapting the signal poles estimates. It leads to a line spectral tracker which is able to robustly estimate the frequencies, even in a noisy context, when the lines are close to each other and when a modulation occurs. HRATRAC is also successfully applied in this paper to a piano note recording.
