I'm a noob with this technical sort of stuff, but I was wondering if the audio processing stuff included in Vista is better or worse than what we had with XP.
Ok, since I am a noob, this is what I have gathered about XP's audio processing--- the k mixer is bad, and it has a degrading effect on the sound unless you decided to take steps to entirely bypass the k mixer. Correct me if I'm wrong about this. So I'm wondering, are there any improvements over XP's k mixer with what comes standard with Vista? |

QUOTE so obviously kmixer changes digital stream in some way But the change that quashes DTS doesn't have t9o be great enough to be perceived with regular stereo material.

DTS encoded wave files can be played through WaveOut/DSound and through the kernel mixer without any loss. And I should know, I've developed a driver for the C-Media 8738/8768 which just can do that stunt. The mixing engine of Vista works with 32bit float samples, so there's actually some information lost in the conversion. But there is a so called "exclusive mode" which is available through the WASAPI. It should give you bitperfect output, albeit I haven't seen software which actually support it (yet). -------------------- http://code.google.com/p/cmediadrivers

Unfortunately that is not case with my card, even with volume slider(s) maxed out in mixer when using DSound in foobar receiver doesn't pick up DTS signal. It briefly switches to DTS but apparently signal is 'week' and receiver reverts back to hissing instantly so IMHO 'contrary to popular belief' kmixer does change signal. It's true that it doesn't effects PCM 44.1 signal but it surely 'destroys' DTS 44.1 stream (at least im my case). ONLY way I can get unchanged DTS signal to my receiver is when bypassing kmixer via ASIO or KS plugin. |
