Comment (by ronak2121):

 So in summary,

 1. Both issues (bad codec info and sample duration) is reproducible
 without a reencode.
 2. Doing a reencode seems to fix the bad codec information but not sample

 I consider both to be defects as fragmentation should not require a re-
 encode (it reduces audio quality & increases fragmentation time) and
 sample duration and codec information should always be correct.
