EAX2.0 onboard, or not?
Subject: General Tech | November 3, 2006 - 01:33 PM | Jeremy Hellstrom
The Tech Report does some serious investigation into 2 onboard EAX2 solutions, Analog Devices' AD1988B codec and Realtek's ALC882D. This testing was initiated because of a White Paper published by Analog Devices, based on testing done by Creative. Find out just how well onboard EAX2 really does work.
"ANALOG DEVICES RECENTLY published a document challenging reviewers not only to benchmark the CPU utilization of integrated audio solutions,
but also to explore how well those implementations handle EAX positional 3D audio. According to the document, most motherboards don't handle
EAX properly, despite the fact that they claim to support the standard. Analog Devices diplomatically avoids naming names, but with the vast
majority of integrated audio solutions powered by Realtek codecs, the writing's on the wall.
The question, of course, is whether it's true. Analog Devices' whitepaper cites tests conducted in Creative's, er, labs, but we're not happy
until we can explore an issue with our own systems in an environment we can control. So, we've rounded up a couple of nearly identical
motherboards with Analog Devices and Realtek codecs to see how they handle EAX positional 3D audio, with conclusive results."
