It seems to me as if some ranges of samples are sometimes skipped when the audio file is being played. When playing the file in Winamp, I see the position indicator often going back in time when this happens, and there are bitrate spikes (that don't match the quality of the audio). Based on this observation, I hope some timestamps in the audio stream might simply be set incorrectly, leading to samples being skipped. Is it possible the samples are skipped in some way, and can they be restored if so? The audio was encoded as an AAC stream, originally stored in MKV. An answer using ffmpeg is preferable, but not necessary.
