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 ALchemy project 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.”

Audigy cards do work with Vista, but with no hardware acceleration (except OpenAL).
