    The invention relates to a method (1) for restoring partials of a sound signal between a peak P[i] and a peak P[i+N] which have a known frequency O and a known phase. The method of the invention involves following steps: estimating (2) the frequency O of each of missing peaks P[i+1] to P[i+N-1] of the partial; a phase shifted from the phase of the peak P[i] to the phase of the peak P[i+N] being calculated (3) for each estimated frequency O; calculating (4) a phase error err between the shifted phase and a known phase at the peak P[i+N]; and correcting (5) each shifted phase according to the phase error err.
