Abstract
A method and an apparatus for concealing an error of an apparatus for receiving an audio frame in a communication system are provided. The includes determining whether the error occurs in a current audio frame that is received from a transmitter, determining whether the audio frame includes a signal that corresponds to a preset specific frequency when the error occurs, setting a gain of the signal that corresponds to the specific frequency to be lower than a preset limit value if the audio frame includes the signal, and concealing the error of the current audio frame based on a previous audio frame of the audio frame in which the error occurs and the gain of the signal that corresponds to the set specific frequency.
