What will AMD's TrueAudio technology mean for soundcards?
Will the tech inside AMD's new GPU's render dedicated internal soundcards obsolete?
No, if you read the article, the technology to is to work in tandem with whatever output device you use. Onboard audio, dedicated card, HDMI. It simply processes the audio for better effects and then sends it back to the sound device, whether it's headset connect to the front jack on a case or HDMI going to a 7.1 surround system.
The true power of dedicated DSP on cards died a long time ago. Now any dedicated card is really just for better headphone amps, lower signal to noise ratio, etc.
This could be exciting if they can get everyone on board. IR based reverbs and sound modeling sound amazing, but do require lots of CPU power. IR is basically sending a base signal through a room and capturing it and making it into a model so that any sound can be processed to recreate how it would sound in that room. Right now, most games when you enter say a bathroom, they just turn up reverb higher to simulate it. With IR, you could actually model a bathroom the exact size of the one in the game and then every footstep, gun shot, water running would echo and be processed exactly as it would in a room that size.
They key with this, and their Mantle API is getting people on board and not letting it go the way of PhysX which is pretty much dead for the most part because it's closed to NVidia hardware only. If AMD can open it up, could be a whole new era of gaming.
