The AWE64 came in two versions initially: A standard version, later re-branded as Value (with 512 KB of RAM), and a Gold version (with 4 MB of RAM, high quality 20-bit DAC and a separate SPDIF output). The boards were based around the AWE32's E-mu 8000 sample-based synthesis chipset, E-mu effects processor, and a Creative audio DSP and codec for digital sound playback. Functionality of the hardware was nearly identical. Quality of components and output was improved and cost of manufacturing was lessened. Their limited production also has made it quite difficult to expand an AWE64's RAM capacity since the AWE64 left production.ĪWE64, in the end, was basically a revision of the AWE32. These memory boards were priced rather high. So, with the AWE64, Creative moved to proprietary RAM expansion modules which only they manufactured and sold. As such, Creative had no control over their sale. These SIMMs were commodity items during the time of AWE32 and AWE64, because they were used for many other applications, including plain system RAM. The Sound Blaster AWE32 boards allowed sample RAM expansion through the installation of 30-pin fast-page DRAM SIMMs. This also made it possible to reduce the size of AWE64's board noticeably, compared to AWE32. Increased integration means the board can be simpler and trace routing to components is reduced, decreasing the amount of noise-inducing signal travel. The improvement also comes from increased integration of components on AWE64 compared to its predecessors. This improvement is most notable with the AWE64 Gold, because of its superior gold plated RCA connector outputs. The inability to adjust synthesis parameters, unlike with the hardware portion of the AWE64, also limited the WaveGuide function's usefulness.Īnother 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.
This not only demands more processing power from the host system, but also is not of equal quality to available SoundFonts. The technology, called WaveGuide, synthesizes the instrument sounds rather than using stored instrument patches like the hardware voices. Unfortunately, these additional voices are achieved via software-based processing on the system CPU. It offers a similar feature set, but also has a few notable improvements.ĪWE64 has support for greater polyphony than the AWE32. The Sound Blaster AWE64 is significantly smaller than its predecessor, the Sound Blaster AWE32.
