Audio restoration by constrained audio texture synthesis

Abstract

Audio texture, a new audio medium, is used to synthesize long audio streams according to a given short example audio clip. In this paper, we extend this idea to audio texture restoration, or constrained audio texture synthesis for restoring those missing parts in an audio clip. It is useful in many applications such as audio restoration and audio reconstruction. It can also be used in error concealment for audio/music delivery with packet loss on the Internet. A novel method is proposed for constrained audio texture synthesis. Preliminary results are provided for evaluation.
