论文摘要
该论文为音频介绍，倾斜和去量化的任务提供了一个统一的灵活框架。该概念将进一步扩展，以涵盖转化的域中的类似降解模型，例如信号的时频系数的量化。从两个不同域中的降解观测值重建音频信号的任务是作为反问题的，并开发了几种算法解决方案。在一个示例中证明了提出概念的生存力，其中进行了对时间域信号的部分和量化观察结果的音频重建及其时间频系数。
The paper presents a unified, flexible framework for the tasks of audio inpainting, declipping, and dequantization. The concept is further extended to cover analogous degradation models in a transformed domain, e.g. quantization of the signal's time-frequency coefficients. The task of reconstructing an audio signal from degraded observations in two different domains is formulated as an inverse problem, and several algorithmic solutions are developed. The viability of the presented concept is demonstrated on an example where audio reconstruction from partial and quantized observations of both the time-domain signal and its time-frequency coefficients is carried out.
