Does A3D use Head-related transfer function for encoding? If so, this might be worth adding to the article. Peter S. 13:02, 12 September 2005 (UTC)[reply]

A3D was the first positional sound system to support HRTF, in fact Creative used the Aureal HRTF technology (which they aquired when they bought Aureal) in EAX 5.

Aureal/Creative Labs lawsuit

[edit]

This article claims that, "Creative Labs sued Aureal in 2000, but lost," while in the Creative Labs article, it states; "The legal battle with Aureal over Creative's infringement of their high-quality 3D audio patents (5,596,644 and 5,802,180). Creative lost this battle, but the legal fees ended up putting Aureal in a poor financial position." I'm changing the text in this A3D article, based on the statement from the Creative Labs article.

That works. The dates for the suit are wrong too; fixed. And removed the reference to A3D being "harder to code" -- both subjective ("free" software that isn't truly free/open source isn't any easier to use than proprietary, as it all depends on the API, and on those grounds, DirectX didn't have the foresight to include a resource manager like A3D 1.0 had until DX7) and a non sequitur in its implication to the demise of A3D (as Aureal had already declared bankruptcy a year before, and been bought out by Creative half a year before, the "early 2001" listed date).

A3D technology in EAX

[edit]

"While Creative Labs has not chosen to support the A3D API, the underlying advanced features of A3D technology is making its way into Creative Labs' newer EAX incarnations."Anyone got a citation for this? It's been seven years since Creative acquired (stole) Aureal's IP and I can find no evidence that any of this technology has found its way into EAX, which remains a simple reverb engine. --DrFod 03:48, 8 March 2007 (UTC)[reply]

Depressing, isn't it? I used A3D back in 1999 with Half-life/Counter-Strike and it was phenominal. EAX still seems to lack real ray-tracing-like audio plotting, which is *the* crucial technology. Creative's effectively monopoly in the sound card field is ruining the market. Toby Douglass 11:57, 20 March 2007 (UTC)[reply]
