Patent ID: 8918196

Claim:
A method for generating an output sequence of samples in response to a first and a second subsequence of samples corresponding to a digitized audio signal received over a network, the method comprising: applying a weighted overlap-add procedure to the first and second subsequences to generate the output sequence of samples; and optimizing a weighting function involved in the weighted overlap-add procedure in response to a measure of matching between the output sequence of samples and one or more target sequences of samples, the weighted overlap-add procedure comprising multiplying the first subsequence sample-by-sample with a first window and multiplying the second subsequence sample-by-sample with a second window, and a shape of at least one of the first and second windows is optimized in response to the measure of matching, and the optimizing includes adjusting at least one of the weighting function involved in the weighted overlap-add procedure or an additional weighting function involved in the weighted overlap-add procedure, the weighting function involved in the weighted overlap-add procedure represented by a set of parameters that are based on a decomposition of a temporal shape of the weighting function into a linear combination of basic window shapes.
