PLC - Packet Loss Concealment
Packet loss occurs when one or more packets of digital voice data traveling across some digital system or network fail to reach their destination. Packet loss can be caused by a number of factors, such as network failure, packets corruption and so on. For sound signals packet loss may cause anoying artifacts such as pops and glitches.
Packet Loss Concealment is a technique used to mask the effects of lost or discarded packets. The objective of PLC is to reconstruct a synthetic signal to cover missing data in a received bit stream and thus hide transmission losses.
