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 18):
A signal processing system for restoring a wrapped audio signal, wherein the wrapped audio signal comprises a plurality of digitised signal samples at respective sample times, the system comprising one or more processors configured to:\n estimate a sequence of corrections comprising a sequence of numerical values to be applied to corresponding values of the plurality of digitised signal samples of the wrapped audio signal, or estimate a sequence of corrected signal samples, the estimating comprising, for each digitised signal sample: applying, at the sample time, a numerical filter to each of a set of potential corrections or set of potential corrected signal samples to determine a filtered value associated with each set of potential corrections or set of potential corrected signal samples, wherein the corrections are integers or the potential corrected signal samples comprise signal samples modified by integer multiples of a correction constant, wherein the numerical 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, each objective value being determined by applying an objective function to the filtered value associated with each set of potential corrections or set of potential corrected signal samples; and determine a sequence of corrections or sequence of corrected signal samples, one for each signal sample, by selecting for each sample time a correction or corrected signal sample from the set of potential corrections or set of potential corrected signal samples for the sample time, wherein the correction or corrected signal sample for each sample time are selected to optimise the cumulative objective; and determine a restored version of the wrapped audio signal using the sequence of corrections or corrected signal samples.
