Abstract:
There is provided an error concealment unit, method, and computer program for providing an error concealment audio information for concealing a loss of an audio frame in an encoded audio information. In one embodiment, the error concealment unit is configured to provide an error concealment audio information using a frequency domain concealment based on a properly decoded audio frame preceding a lost audio frame. The error concealment unit is configured to fade out a concealed audio frame out according to different damping factors for different frequency bands.
