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 8):
A method as claimed in  claim 1 , the method further comprising:\n refining a previous estimation of the restored audio signal, the refining comprising: reusing the previous estimation of the restored audio signal as a further input audio signal; estimating one or more further sequence of corrections comprising a sequence of numerical values to be applied to corresponding values of the plurality of digitised signal samples of the further input audio signal, or estimating a further sequence of corrected signal samples; determining a refined restored version of the wrapped audio signal using the further sequence of corrections or further corrected signal samples.
