For the most part, you're right about the source files(Sabat has some material in better quality), but remember; the audio you're hearing here is the raw audio(With lossy compression run over it).Jinzoningen MULE wrote:Though if I'm right in assuming this leak is (basically) exactly what Sabat has
If Funimation put some work into EQing, some light noise reduction, and some professional work on the fansub audio for the missing sections, the result could end up rather incredible(Particularly if they encode it lossless). Whether they'll put as much work in as I'm suggesting is another matter, but at the very least, they should be able to make it sound a little nicer than the leak. Plus, as I say, Sabat does have some material in better quality than what leaked.
As for the quality of the fansubs; some fansubs(Most fansubs of the original series, for example) come from rebroadcasts and such which use the lower-quality optical audio you hear on the Dragon Boxes as their original source, or the tape has gone through too many generations for the audio to come through.
Some fansubs, however, can -- with a lot of work -- be processed to sound really nice. Not as good as the proper broadcast audio, particularly if that broadcast audio has been properly processed, but certainly an improvement over the Dragon Boxes.
I do hope someone out there has a fansub of at least some of the original series that's sourced from an original broadcast; that way, Sabat would have improved audio for all three original series.
