Vortex 1 sound card with AU8820B2-chip Vortex 2 logo branding. The Vortex audio accelerator chipset line from Aureal Semiconductor was designed to improve performance of their then-popular A3D audio technology. The first member of the line, the Vortex AU8820, was announced on July 14, 1997, [4] and was used in by a number of sound card ...
The Diamond Monster Sound MX300 was based on the Vortex2 audio ASIC from Aureal Semiconductor. It was a substantial step forward in gaming audio, with impressive 3D audio positioning and other effects. It utilized the then state-of-the-art Aureal A3D 2.0 3D audio API.
The card was based on the Aureal AU8830 (Vortex 2) chipset but differed from the reference Aureal design. The Quadzilla was the 4-channel version and achieved this via a separate daughtercard, whereas the other AU8830 cards such as Aureal Vortex SQ2500 and Diamond Monster Sound MX300 used a single card.
Crystal River Engineering was acquired by Aureal Semiconductor in 1996. [1] Crystal River's innovations in the field of real-time 3D audio processing were published in a series of papers [2] by NASA's Elizabeth Wenzel and Crystal River's Scott Foster.
The firm had maintained a strong foothold in the ISA PC audio market until 14 July 1997 when Aureal Semiconductor entered the soundcard market with their very competitive PCI AU8820 Vortex 3D sound technology. The firm at the time was in development of their own in house PCI audio cards but were finding little success adopting the PCI standard.
Media Vision was the original equipment manufacturer (OEM) of the Logitech SoundMan (also marketed as Pro AudioSpectrum 16 Basic) card, which was compatible with the PAS and could thus use the same drivers. The relevance of the PAS faded quickly as Media Vision was rocked by financial scandal and faded from existence.
Also known as Sound Blaster Audigy ADVANCED MB, it is similar to Audigy 2 SE, but the software supports EAX 3.0, which supports 64-channel software wavetable (sample-based synthesis) with DirectSound acceleration, but without hardware accelerated 'wavetable' sample-based synthesis. DAC is rated 95 dB Signal-to-Noise Ratio.
