| Title: | HRHATRAC Algorithm for Spectral Line Tracking of Musical Signals | ||
| Authors: | Bertrand David, Roland Badeau, Gaël Richard, GET / Télécom Paris, France | ||
| 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. | ||
