Sound Blaster PCI 128 is Creative's low cost
audio PCI solution for good quality 3D gaming. Built upon the PCI bus architecture, it uses PCI bus-mastering to
stream audio from the card to the host memory without any need for on-board
RAM-freeing up valuable CPU resources for other tasks. With Sound Blaster PCI
128, users will be able to experience the depth and realism offered by the
Environmental Audio Extensions (EAX), Microsoft DirectSound and DirectSound 3D
supported games.
