We knew that already, nothing new here.
A good example of this is DTS audio.. DTS audio is a much larger file format and is less compress than AC3. A good comparison example would be.. DTS = CD Wave and AC3 = MP3.. AC3 is a compressed format.
That's a horrible example, it's more like DTS=MPEG-2 DD=VC-1 (or H.264). DTS is a lossy codec, same as DD or MP3.
A good DTS audio track found on current dvd's could be for example approximately 1.1 gig, the equivalent AC3 track (dependant on bitrate) would be around 400 MB.
That doesn't mean anything.
While for music many claim MP3 to be the same,
Nobody claims that, at least nobody sane.
for the Low/high frequencies found outside of the music spectrum like what we need to drive our sub and astute sounds in a movie sound track DTS is a much better sound.
Basically the Xbox 360 will be compressing the audio mixes to AC3, and from what they are saying because they need to also integrate the sound of the dash/alert popups during the movie, all audio will be recompressed to AC3?
Yes, as well as all the HD DVD supplimentary sounds, like IME, menues etc, just like every DVD player in existance.
I hope this isn't correct, but that means it will take an original AC3 soundtrack and recompress it to another AC3 soundtrack with the addition of the dashboard sounds.
HD DVDs use DD+ or DTHD, DTHD is lossless, and DD+ is better than DD.
Thats like Recompressing an MP3, or a JPG. Lets hope this isn't the case.. But it is bad news for the audiophiles who love their DTS.
The 360 addon isn't for audiophiles, that's what set top players are for.
