Abstract:
1. A method for processing a sequence of frames of coded audio data comprising the steps of: identifying a sequence of lost frames of coded audio data as being lost or corrupted, wherein the sequence of lost frames comprises one or more lost frames; identifying a first frame of coded audio data, which immediately preceded the sequence of lost frames of coded audio data, as having been encoded using a time domain coding method; identifying a second frame of coded audio data, which immediately followed the sequence of lost frames of coded audio data, as having been encoded using a transform domain coding method; generating replacement audio samples for the sequence of lost frames based on the first frame of coded data; obtaining a pitch delay from at least one of the first and second frames of coded audio data; generating a second decoded audio portion of the second frame based on the second frame of coded audio data; generating a first decoded audio portion of the second frame based on the pitch delay and at least one of the second decoded audio portion and the replacement audio samples; and generating a decoded audio output of the second frame based on a sequential combination of the first and second decoded audio portions, wherein the first decoded audio portion is determined as wherein ŝ
