What, exactly, is Audio Error Concealment?
Audio Error Concealment is a Quality of Service implementation for audio in video calls over IP or H.320 networks. In the presence of packet loss due to traffic or instability on the network, Audio Error Concealment will activate and work to reduce the loss of sound bits during the call. This will work in any of the supported audio standards, including G.711, G.728, G.729A, G.722, G.722.1 and Siren 14. This unique method of audio error concealment is a function of the VSX decode process (receiving side of the audio), meaning that it will correct corrupted audio from the endpoint. The results are reproduced audio segments (that would have otherwise been dropped), allowing for a smoother, less distracting conversation during the video call.
