Default Re: Buducnost Audio Tehnike...

zanimljiva tema.

kod softvera ce pre svega sve biti prebaceno na 64bita tako da ce potreba za upsemplovanjem/downsemplovanjem nestati, a samim tim ce cpu potrosnja biti manja. ocekujem u narednim mesecima pocetak prelaska programa na 64bitne verzije.

sto se tice viste evo jednog navoda

Over the years, we've realized that there three major problem areas with the existing audio infrastructure:

1. The amount of code that runs in the kernel (coupled with buggy device drivers) causes the audio stack to be one of the leading causes of Windows reliability problems.
2. It's also become clear that while the audio quality in Windows is just fine for normal users, pro-audio enthusiasts are less than happy with the native audio infrastructure. We've made a bunch of changes to the infrastructure to support pro-audio apps, but those were mostly focused around providing mechanisms for those apps to bypass the audio infrastructure.
3. We've also come to realize that the tools for troubleshootingaudio problems aren't the greatest - it's just too hard to figure out what's going on, and the UI (much of which comes from Windows 3.1) is flat-out too old to be useful.

Back in 2002, we decided to make a big bet on Audio for Vista and we committed to fixing all three of the problems listed above.

The first (and biggest) change we made was to move the entire audio stack out of the kernel and into user mode. Pre-Vista, the audio stack lived in a bunch of different kernel mode device drivers, including sysaudio.sys, kmixer.sys, wdmaud.sys, redbook.sys, etc. In Vista and beyond, the only kernel mode drivers for audio are the actual audio drivers (and portcls.sys, the high level audio port driver).

The second major change we made was a totally revamped UI for audio. Sndvol32 and mmsys.cpl were completely rewritten (from scratch) to include new, higher quality visuals, and to focus on the common tasks that users actually need to do. All the old functionality is still there, but for the most part, it's been buried deep below the UI.
trenutno se vodi rat izmedju sacd i dvd-audio formata, ali u svakom slucaju 44.1KHz/16bit je odavno zreo za penziju.
povecanjem snage danasnjih kompjutera, vece rezolucije ce svakako postati standard (24bit).

sto se tice hardvera, mislim da je buducnost u spoju digitalnog i analognog, tj. iskoriscenju najboljeg iz oba sveta.
