"The Acoustic Edge is powered by Philips' own SAA7785 ThunderBird Avenger
DSP chip. This audio accelerator can process 256 sounds simultaneously and
actually offloads digital mixing and Directsound processing from your CPU.
This becomes important when you consider that the card has some
sophisticated features that would otherwise put added stress on your system.
As it is, many of the card's special processing features are "free". The
chip can also process 96 streams of 3D accelerated audio including
positional reverb, so it is a fairly powerful and full featured DSP chip."
