looks fine to me... assuming when you play the file back in a
player that it sounds right. if it weren't then the first thing
I would guess is that the byte order is wrong, which will ruin
with LPC encoding on CD audio you usually want a larger block
size (flac -5 defaults to 4608, FLAC__StreamEncoder defaults
to 1152). but that shouldn't make so much of a difference.
it could be something subtle with the conversion from bytes
to ints. rip the data to a wave, then rip the data to flac
and decode to wave, then compare to see if their the same.
