Beschreibung
Zusammenfassung:	Audio receiver processor for processing an error protected frame, comprising: a receiver interface (300) for receiving the error protected frame to obtain a received error protected frame; an error protection processor (302) for processing the received error protected frame to obtain an encoded audio frame, wherein the error protection processor is configured to check whether a codeword of a first predefined subset of codewords of the encoded audio frame comprises an error, and an error concealer or an error concealment indicator (304) configured to perform a frame loss concealment operation or to generate a frame loss concealment indication in case of a detected error in the first predefined subset of the codewords.
