Ashbringer Wrote:Don't know how Trueaudio is going to reduce cpu load, but long time ago we had this thing called hardware sound acceleration. You know, where you use the sound card's cpu to do sound, instead of the main CPU in your machine? This used to exist with Direct Sound before Microsoft removed it in Vista on up. Now it only exists in OpenAL, and the only sound card that uses this is Creative Sound Cards.

Sound cards don't have a cpu. They have a DSP. Asus DSPs can do SOME hardware acceleration in openAL too if I recall. Both directsound and openAL only ever had very limited hardware acceleration for advanced environmental effects and 3d positional calculations. And yes trueaudio is a hardware accelerated API. AMD is planning to begin including DSPs for it in future graphics cards.

True Audio is not a dedicated Sound Card with Audio I/O , it simply offloads Audio tasks from the CPU which are then sent to the Sound Card.. So you can utilize True Audio DSP and a Creative X-Fi Soundblaster at the same time.

codec != DSP

I never said that it had an audio codec onboard.
