1 A Simple Prior For Audio Signals

Abstract—We propose a simple prior for restoration problems involving oscillatory signals. The prior makes use of an un-derlying analytic frame decomposition with narrow subbands. Other than this, the prior does not have any other parameters, which makes it simple to use and apply. We demonstrate the utility of the proposed prior through some real audio restoration experiments. Index Terms—Inverse problem, audio prior, audio inpainting, saddle point. I
