摘要:

信号处理中的动态范围限制经常导致信号中的削波或饱和。音频削波的任务是估计原始音频信号,给定其削波测量,并且近年来引起了很大的兴趣。音频去唇算法通常对底层信号(例如稀疏性或低秩)以及测量系统做出假设。在本文中,我们提供了一个广泛的审查,在文献中提出的音频declipping算法。对于每种算法,我们提出了关于音频信号,建模域和优化算法的假设。此外,我们提供了一个广泛的数值评估流行的declipping算法,真实的音频数据。我们评估每个算法的信号失真比,并使用感知指标的声音质量。本文附带了一个包含评估方法的存储库。

英文摘要:

Dynamic range limitations in signal processing often lead to clipping, or saturation, in signals. The task of audio declipping is estimating the original audio signal, given its clipped measurements, and has attracted much interest in recent years. Audio declipping algorithms often make assumptions about the underlying signal, such as sparsity or low-rankness, and about the measurement system. In this paper, we provide an extensive review of audio declipping algorithms proposed in the literature. For each algorithm, we present assumptions that are made about the audio signal, the modeling domain, and the optimization algorithm. Furthermore, we provide an extensive numerical evaluation of popular declipping algorithms, on real audio data. We evaluate each algorithm in terms of the Signal-to-Distortion Ratio, and also using perceptual metrics of sound quality. The article is accompanied by a repository containing the evaluated methods.
