Audigy owners will get ALchemy, for a low cost, later this year
Microsoft Windows Vista features a new audio stack, which completely revamps how the operating system communicates with audio devices. The new audio stack, dubbed
Universal Audio Architecture
, or UAA, requires companies to develop new drivers. Hardware accelerated audio devices are treated as an independent device, separate from the audio output capabilities of a sound card under Windows Vista.
The way UAA handles hardware DSPs is a problem for Creative Labs when it comes to delivering hardware acceleration for DirectSound 3D and EAX algorithms. Earlier this year Creative Labs launched its
that enabled hardware-accelerated audio on Sound Blaster X-Fi owners. ALchemy translates DirectSound 3D and EAX calls into OpenAL, which can still take advantage of the DSP hardware.
Creative Labs left Sound Blaster Audigy owners in the dark, in regards to hardware-accelerated audio in Windows Vista. However, Creative Labs stated ALchemy support for Sound Blaster Audigy 2 and 4-class products are to be determined depending on demand. Due to demand, Creative Labs has
begun ALchemy development
for Sound Blaster Audigy-series sound cards.
Creative Labs expects to have ALchemy for Audigy sound cards later this year. It does not appear as if ALchemy will be free to current Audigy owners. Nevertheless, when the cards are ready, Creative Labs “hopes to offer this product as a low-cost upgrade to interested Audigy owners.”

A3D was superior to EAX back then, and it calculated the sound based on the actual 3D areas in the game data. And the sad thing about it is that they actually won the lawsuit that creative threw at them, they just couldn't recover from all the legal expenses of the process...
