A method and an apparatus for packet loss concealment, and a decoding method and an apparatus employing same are disclosed. A method for time domain packet loss concealment includes checking whether a current frame is either an erased frame or a good frame after the erased frame, when the current frame is either the erased frame or the good frame after the erased frame, obtaining signal characteristics, selecting one of a phase matching tool and a smoothing tool based on a plurality of parameters including the signal characteristics, and performing a packet loss concealment processing on the current frame based on the selected tool.
A method for time domain packet loss concealment comprising:
The method of claim 7, wherein an energy change level between an overlap duration and a non-overlap duration as a result of the smoothing processing is compared with a predetermined threshold, and the OLA processing is performed instead of a smoothing processing as a result of the comparison.
Dependencies are inferred from the claim text.
