Abstract:
A computer-implemented method for restoring a wrapped audio signal comprising a plurality of digitised signal samples at respective sample times, the method comprising: estimating a sequence of corrections comprising a sequence of numerical values the estimating comprising, for each signal sample: applying, at the sample time, a numerical filter to each of a set of potential corrections to determine a filtered value associated with each set of potential integer corrections wherein the filter enhances the filtered value at sample times when a change in a degree of wrapping occurs relative to sample times when a change in degree of wrapping does not occur; determining a cumulative objective over a plurality of signal samples by accumulating objective values and determining a sequence by selecting for each sample time a correction from the set of potential corrections wherein the correction for each sample time are selected to optimise the cumulative objective.

Claim (Index 16):
A method as claimed in  claim 14 , further comprising:\n determining the cumulative objective, for each of a set of paths, each path comprising a time sequence of the potential wrapping states, one for each sample time, wherein the cumulative objective is determined for a path by accumulating the objective value from the filtered value for transitioning from each potential wrapping state in the path to the next potential wrapping state in the path, and wherein the filtered value for transitioning from each potential wrapping state in the path to the next potential wrapping state in the path is determined based only on the subset of signal samples.
