The inability to adjust synthesis parameters, unlike with the hardware portion of the AWE64, also limited the WaveGuide function's usefulness.
Another improvement comes from better on-board circuitry that increases the signal-to-noise ratio and overall signal quality compared to the frequently quite noisy AWE32 and Sound Blaster 16 boards.
Increased integration means the board can be simpler and trace routing to components is reduced, decreasing the amount of noise-inducing signal travel.
The Sound Blaster AWE32 boards allowed sample RAM expansion through the installation of 30-pin fast-page DRAM SIMMs.
Creative created a motherboard port called the SB-Link that assisted the PCI bus in working with software that looked for the legacy I/O resources of ISA sound cards.
This card added 4 speaker surround sound for games, and a hardware Dolby Digital decoder.
In response to Creative's move towards a proprietary memory module, Jeff Briden created an adapter board that plugged into the AWE64 and allowed the user to install normal 30-pin SIMMs.
In 1998, Beijing Luck Star Power Machines Co, Ltd. had designed an adapter board named SIMMConn that could be plugged into AWE64 and allowed to install a single 72-pin SIMM module.
Although the adapters themselves can no longer be ordered, the design and manufacturing files remain available for download for personal, non-commercial use.
