This paper provides an extensive numerical evaluation of popular declipping algorithms proposed in the literature, in terms of the Signal-to-Distortion Ratio, and also using perceptual metrics of sound quality.
It is shown that the SS PEW method based on social sparsity combined with the proposed method performs comparable to top methods from the consistent class, but at a computational cost of one order of magnitude lower.
This work develops the analysis (cosparse) variant of the popular audio declipping algorithm and extends both the old and the new variants by the possibility of weighting the time-frequency coefficients, finding the proposed analysis variant incorporating PEW slightly outperforms the synthesis counterpart in terms of an auditorily motivated metric.
Adding a benchmark result helps the community track progress.
