Windows 8 to use hardware-assisted sound?

Sound Blaster recently announced some new sound cards. In the process of reading about them, I saw a few posts that Windows 8 will be returning to allowing the use of hardware-assisted audio (please forgive my lack of technical terms here).

What I remember (as a user) was that sound was previously improved by add-on cards years ago, then with Windows 7, no hardware calls were allowed for sound, so all processing was done by the CPU. It seemed to me that games eventually no longer attempted to use EAX or other special sound effects.

With this aforementioned change in Windows 8, will there be a return to improvements in audio effects for games? Will it affect Windows in any other noticeable way? And can anyone point me to any info or articles about that change? I haven't read anything detailing that change to Windows 8.

The answer to both questions is "probably not". The purpose of exposing hardware is because tablets are too slow to do audio entirely in software. This hardware isn't being exposed so that applications can use specific hardware features, but rather that all the processing/rendering can be pushed (back) into hardware. To that end I'm not even sure if we're going to see that functionality used with x86 hardware; it's almost by definition for ARM SoCs. Also, this functionality is only for Metro, so AAA games (which for the time being I would expect to remain as desktop applications) cannot use this functionality.

And can anyone point me to any info or articles about that change? I haven't read anything detailing that change to Windows 8.

Thanks a ton! That absolutely explains the whole thing and it makes perfect sense. I wondered why they would go back and expose the hardware.

I'll be interested to see if Windows 8 makes any compromises for PCs by trying to incorporate so many other hardware platforms. It's hard to be everything to everyone...
 
Strange . . . I always thought speakers were hardware as well as headphones and earbuds. 🙂
