Initially I was looking for a Dolby Digital Live soundcard to output game audio to an external processor for virtual Dolby Headphone processing. Most Asus and Creative soundcards already support DDL. However, Asus cards also directly output Dolby Headphone and Creative cards output CMSS-3D. I was wondering what the difference is?
I've been told that maybe with CMSS-3D you can hear a little better where the noise is coming from, and with Dolby it's easier to identify what the noise is. But that was just what one person said. Is that a fair assessment of the difference?
I believe Dolby Headphone works by taking the native 5.1 audio and uses that to create virtual surround over 2 headphone speakers which would seem to be the most accurate way to achieve a sense of surround sound from 2 speakers. Does CMSS-3D do the same thing by using the native 5.1?
How does Dolby Headphone and CMSS-3D differ exactly?
Which do you recommend and why?
Also are there any alternatives to Dolby Headphone or CMSS-3D that would create a better virtual surround over headphones?
