Abstract
This paper presents an efficient model-based interpolator for reconstructing long portions of missing samples in audio signals. A simple modification to an existing interpolation method is proposed, optimizing the balance between computational requirements and qualitative performance. Moreover, a post-processing multirate interpolation scheme is introduced to further enhance the quality of the restored signals. Subjective quality assessments of the reconstructed signals via listening tests substantiate the improved performance of the proposed algorithm
