AB  - This paper introduces a partial-tracking algorithm suitable for the sinusoidal modelling of polyphonic sounds. A new method, based on the backward exploration of possible extensions of the partials in future frames, is proposed to cope with the lack or corruption of spectral data. The allocation of spectral peaks to a partial is done by considering possible trajectories in future frames where frame hoping is allowed. A suitable transition probability that takes into account missing or rejected peaks is proposed. The trajectory that exhibits the highest probability is searched for and the corresponding peak for the current frame is chosen to extend the partial.
