Codec for Immersive Voice and Audio Services (IVAS); Error concealment of lost packets
The present document defines a frame loss concealment procedure, also termed frame substitution and muting procedure, which is executed by the Immersive Voice and Audio Services (IVAS) decoder when one or more frames (speech or audio or SID frames) are unavailable for decoding due to e.g. packet loss, corruption of a packet or late arrival of a packet.
