An enhanced smart copying (ESC) method for the reconstruction of missing audio packets

The paper describes an improved statistical approach for the reconstruction of missing audio packets. We demonstrate that the proposed enhanced smart copying method can successfully reconstruct lost packets with a much reduced computational time (approximately 21 times faster), while giving better quality as compared to the existing scheme. This efficiency is achieved by avoiding the direct inversion of a large matrix and requires no explicit solution for the coefficients of the underlying autoregressive model.
