I don't think that he means that the compression is
removing time as part of the compression directly --
it's an artefact of the compression process, rather.
ATRAC and MP3 both work by dividing the source up
into a large number of small chunks and picking
the best encoding strategy per chunk (which is why
So unless the chunk size exactly divides the track
size, there's going to be a chunk that's too small
at the end.
If I were writing the encoding, I'd throw away that
last little chunk if it were "completely empty",
otherwise I'd pad it with emptiness. So the length
would change just a little bit...
This is just my guess, but that's how I'd go about it.
