摘要:

本文提出了一个统一的,灵活的框架,音频修复,declipping和去量化的任务。该概念被进一步扩展以覆盖变换域中的类似退化模型,例如信号的时频系数的量化。从两个不同的域中的退化观测值重建音频信号的任务被制定为逆问题,并开发了几种算法解决方案。所提出的概念的可行性证明了一个例子,其中进行音频重建从部分和量化的观察的时域信号和它的时间-频率系数。

英文摘要:

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.
