Low Delay Error Concealment for Audio Signals
https://www.tnt.uni-hannover.de/papers/data/934/AES46th_paper_err_con.pdf
Preihs et al. Low Delay Error Concealment for Audio Signals utilizes an AR-process: x(n)= p ∑ k=1 a kx(n−k) (6) with {a 1,a 2...,a p} being the AR-coefficients. The AR-coefficients can be identified by system identification al-gorithms like the ones described in the next paragraph. The AR-model has several benefits e.g. it is simple to

This paper is concerned with error concealment in digital audio signals. Two model based methods for signal extrapolation are developed and compared. Among these is the usage of adaptive Kalman filtering which can be processed with zero algorithmic delay

Dept. of Signal Processing and Communications Helmut-Schmidt-Universität Hamburg, Germany [email protected] ABSTRACT A major problem in low-latency Audio over IP transmission is the unpredictable impact of the underlying network, leading to jitter and packet loss. Typically, error concealment strategies are em-ployed at the receiver to counteract …

propose a low-cost period extraction and alignment module to synthesize concealment signals from previous raw audio data, thus avoiding the use of autoregressive models in order to reduce the computation time. Period extraction is based on zero-crossings and matched pre-processing.

A low delay audio coding scheme for communications applications is proposed. Its compression ratio is comparable to current state-of-the-art audio coding schemes, but with a much lower delay.

For example, assume there are four VLCs (VLC m, VLC n, VLC k, and VLC l) and they are listed in the order in which they appear in the DHT segment.If the three unused VLCs (VLC n, VLC k, and VLC l) are mapped to the same used VLC m, then the mapping set is {VLC m ↔ {VLC n, VLC k, VLC l}}.To map codes, the (run, size) values of VLC n, VLC k, and VLC l are all modified to that …
