Comment (by slhck):
Replying to [comment:2 heleppkes]:
> This is normal and expected behavior of any AAC encoder. It produces
"preroll" data that the decoder is supposed to skip.
How does the decoder know it's pre-roll data? Like I mentioned, if you re-
encode the file multiple times it's not skipped, but added up.
