Abstract

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 time-frequency coefficients. The problem of restoring 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 restoration from partial and quantized observations of both the time-domain signal and its time-frequency coefficients is carried on.
