packet loss concealment (codec) (PLC)

Packet Loss Concealment(PLC) can be translated as packet loss concealment. Packet loss concealment is about improving the reduced voice quality in case of packet loss.

In IP-based voice transmissions such as Internet telephony or voice streaming, voice quality depends on several factors, one of which is packet losses that interfere with voice transmission.

In several voice codecs such as G.711 or iLBC(Internet Low BitrateCodec), packet loss concealment is therefore used as a compensation method to suppress short-term voice interference in the event of packet loss. According to the procedure, the last tone transmitted before the interruption is retained for a longer period and interpolated with the first tone following the interruption.
