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 3):
A method as claimed in  claim 1  wherein a potential wrapping state comprises a plurality of potential corrections from the set of potential corrections or a plurality of potential corrected signal samples from the set of potential corrected signal samples, and wherein there are multiple potential wrapping states for each sample time; the method 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, \n 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 \n 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 for the plurality of potential corrections or plurality of potential corrected signal samples defined by both the potential wrapping state and next potential wrapping state; and \n identifying an optimum path which identifies the sequence of corrections or corrected signal samples used to determine the restored version of the wrapped audio signal.
