本文提出了一种有效的模型为基础的重建音频信号中的缺失样本的长部分的重建。一个简单的修改现有的插值方法，提出了优化计算要求和定性性能之间的平衡。此外，后处理多速率插值方案被引入，以进一步提高恢复信号的质量。通过收听测试对重构信号的主观质量评估证实了所提出的算法的改进性能
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
