In this article, we present an enhanced algorithm, of low complexity , for the tracking of partials in the context of sinusoidal modeling. By considering the past evolution of each partial in the time/frequency and time/amplitude planes to predict its future evo-lutions, this algorithm allows a better discrimination between sinu-soidal and noisy components and an easier cancellation of sudden changes in the evolutions of the partials.
