ABSTRACT:
An arrangement which utilizes the system memory to store the wave tables used in the generation of high quality sound, and a direct memory access controller to rapidly transfer the portions of the wave tables stored in memory using the system bus so that a sound card may manipulate high quality sounds from wave tables stored directly in system memory without overloading the system bus and without the need for substantial additional memory on the sound card.
