Packet Loss Concealment (PLC) algorithms, also known as frame erasure concealment algorithms, hide transmission losses in an audio system where the input signal is encoded and packetized at a transmitter, sent over a network, and received at a receiver that decodes the packet and plays out the output. Many of the standard CELP-based speech coders, such as Recommendations G.723.1 [l],G.728 [2] and G.729 [3], have PLC algorithms built into their standards. The algorithm described here provides a method for Recommendation G.7 1 l.
