Computer Science. Journal of The Audio Engineering Society. In this work we present a novel approach for audio packet loss concealment, designed for MPEG-Audio streaming, based only on the data available at the receiver. The proposed method is based on the GAPES (Gapped-data Amplitude and Phase Estimation) algorithm for replacing the missing …

Abstract: In this work we present a novel approach for audio packet loss concealment, designed for MPEG-Audio streaming, based only on the data available at the receiver. The proposed method is based on the GAPES (Gapped Amplitude and Phase Estimation) algorithm for replacing the missing data, using interpolation in the spectral domain.

PLC stands for Packet Loss Concealment. PLC describes any method of generating new audio data when packet loss is detected. In Asterisk, there are two main flavors of PLC, generic and native. Generic PLC is a method of generating audio data on signed linear audio streams. Signed linear audio, often abbreviated "slin," is required since it is a ...

A new technique for audio packet loss concealment. Abstract: We present a new error concealment technique for audio transmission over heterogeneous packet switched networks based on time-scale modification of correctly received packets. An appropriate time-scale modification algorithm, WSOLA ("Waveform Similarity Overlap-Add"), is used and its …
PACKET LOSS CONCEALMENT FOR MDCT-BASED AUDIO …

lost packets of MP3 audio using side information. First, we discuss packet loss conceal-ment based on packet copy for an MDCT-based audio codec, and point out problems that deteriorate the quality of the restored signal. Then we propose a packet loss concealment method using sign correction. The proposed method uses signs of lower MDCT coffi
