Windows 7 će imati Dolby Digital Plus podršku

[PCAXE_news]

Konačno je došlo vreme kada će Vaš operativni sistem znati kako da sluša digitalne surround zvuke. Dolby laboratorija je izjavila da će Windows 7 imati u sebi nativnu podršku za Dolby Digital Plus standard u okviru novog operativnog sistema iz Microsofta i on će se nalaziti u edicijama Home Premium, Proffesional, Enterprize i Ultimate.

Ljudi, sredite malo kodiranje, ili bar ispravite tekst da liči na nešto, ovako sa znacima pitanja umesto slova je ružno.

Svesni smo problema i radimo na njemu. Za sada ručno prepravljam svaku vest koju bot pokupi sa sajta, međutim kada se ode na sajt tj kada klkneš na link, tih znakova pitanja nema.

Ovo je samo takozvani preview vesti, i zaista se trudim da što pre odreagujem kako se ne bi primećivalo.

Da li to znaci da mi koji vec imamo OjEM verziju da imamo i tu podrsku za dolbe?

Izgleda da dolazi vreme kada će prosečnim korisnicima biti potrebno nešto više od malenih kompjuterskih zvučnika.... mmmda

The shocker came when we compared the lower 448 kbps Dolby Digital DVD bitrate to the original. There was an audible difference, but it was only ever-so-slightly noticeable (and this is with a high end audio system in an acoustically controlled environment that is so far beyond what typical home theater systems are capable of resolving). There was just the slightest decrease in presence with the DD version, not exactly a softening of the sound, but just a tad less ambience and a similarly small tightening of the front soundstage’s depth. Quite a remarkable result, I thought, and I was highly impressed with how much fidelity can be packed into such a relatively small amount of bitspace. If I was doing actual scoring, I would have awarded a 4.8 grade to the results I heard – the audible difference was that subtle.

It was déjà vu all over again. We switched back and forth between the original PCM master and the core DTS version, and here we found only the slightest, barely noticeable difference. From a frequency response standpoint, both versions were identical, with clearly delineated high frequency details, but the compressed version differed slightly only in barely noticeable presence —that sense of being “there”, with the original PCM track having just slightly greater overall richness. Whatever acoustic elements were removed in the code/decode process were clearly superfluous, at least for the most part, as the audible differences were so minor as to be almost unnoticeable—again, another testament to the capabilities of this highly refined codec.

What impressed, or perhaps surprised, me most about these tests was how good the base codecs actually are. The difference between the original audio and the basic Dolby Digital and DTS is a lot subtler than you’d expect, given the extreme amount of compression (around 10:1, a similar ratio to that of 128 kbps MP3).

That said, I could definitely **** out the difference between the lesser (or perhaps it’s more accurate to say “better”) compressed versions and the higher compressed versions. The difference is mostly in the presence, or ambience. The lossless, Dolby Digital Plus, and DTS-HD High Resolution compressed tracks were just a little more open and airy. I hate to say it, but they just sounded more realistic and transparent. The 448 kbps Dolby Digital and standard DTS tracks were less so, a little more closed off. Between the 640 kbps Dolby Digital and the uncompressed, the difference was even less noticeable. Enough so that most people, even those trained to listen for it, probably won’t be able to hear the difference.

The core DTS call is a little harder, as there wasn’t the same blind system in place to A/B as precisely as at Dolby. Results were similar, though.So by all means go for the new codecs, as they definitely sound better than what was on DVD. Uncompressed PCM, on the other hand, is just a waste of space (though compatible with everything).

If you’ve been listening at home and are sure you can hear a difference on your favorite discs, be wary. There is absolutely no way to tell that compressed and uncompressed tracks on any disc have anything to do with each other. They could come from different masters, they could be mixed differently, or any number of other variables that makes an in-home test, unfortunately, impossible. That said, trust your ears, and go with the one that sounds best to you.

Hard core hi-fi manijaci ce uvek cuti razliku u zvuku ma koliko mala ona bila. Sjajna je stvar kako je dobro odradjen dolbijev kodek, jedva je njihovo "zlatno uvo" primetilo razliku dok pisac vesti nije cuo bilo kakvu razliku u odnosu na sirov nekompresovani zvuk. Recenica simbolicno opisuje napredak operativnih sistema i njohovu podrsku za razne tehnologije, pa i ovu, na malenim kompjuterskim zvucnicima ce retko ko primetiti razliku.

eh da, jako me interesuje tvoja konfiguracija, mislim da nisam imao prilike da procitam negde sta koristis, tipujem na laptop.

Ja? Yes, C2D + Turion 64 lapove i desktop kao media server, za sad . Upgrade je u toku.

Malo detaljnije o tome sta je "problem" u ranijim verzijama Windowsa. Fali jos "samo" da player SW podrzi sve.
