Aureal Semiconductor Inc. was an Americanelectronics manufacturer, best known throughout the mid-late 1990s for their PC sound card technologies including A3D and the Vortex (a line of audio ASICs.) The company was the reincarnation of the, at the time, bankrupt Media Vision Technology, who developed and manufactured multimedia peripherals such as the Pro Audio Spectrum 16.
History[edit]
On March 5, 1998 Creative Labs sued Aureal for patent infringement. Aureal countersued because they believed Creative was guilty of patent infringement. After numerous lawsuits Aureal won a favorable ruling in December 1999,[1] which vindicated Aureal from these patent infringement claims, but the legal costs were too high and Aureal filed for bankruptcy. On September 21, 2000, Creative acquired Aureal's assets from its bankruptcy trustee for US$32 million through the bankruptcy court, with the specific provision that Creative Labs would be released from all claims of past infringement by Creative Labs upon Aureal's A3D technology. The purchase included patents, trademarks, other property, as well as a release to Creative from any infringement by Creative of Aureal's intellectual property including A3D. The purchase effectively eliminated Creative's only competition in the gaming audio market. It also eliminated any requirements for Creative to pay past or future royalties as well as damages for products which incorporated Aureal's technology.

Technologies and products[edit]
Contrary to OEM companies (such as Creative which builds, brands and sells their own devices), Aureal was a fabless semiconductor company. This changed with their final product: the Aureal SuperQuad. However, to not anger the middlemen, Aureal did no marketing of its self-branded product.[citation needed]
Vortex[edit]
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,[2] and was used in by a number of sound card manufacturers, like Yamaha and Turtle Beach. After Aureal's release of A3D 2.0, the Vortex AU8830 (known as the Vortex 2) was announced on August 6, 1998.[3] The Vortex 2 chipset won numerous industry awards, and was used among other places in the Diamond Monster Sound MX300, which achieved near-cult status with audiophiles and gamers for the high quality of its positional audio.
Near the end of Aureal's existence, they released a Vortex Advantage budget sound card aimed at systems integrators, which ran on the Vortex AU8810 chipset.[4]
All Vortex soundcards are still functional with latest Windows 2000/Windows XP drivers in Windows Vista and Windows 7 (32 bit editions only). While Windows XP will recognize and work with the 8830 Vortex 2 chipset, there is an official Final Beta (v5.12.2568.0) available for download from a variety of sites which can be found via most internet search engines. There is also a modified version of the XP driver that can provide basic audio functionality for the Windows Vista operating system and may also function with Windows 7 beta releases.[citation needed]
A3D[edit]
A3D (Aureal 3-Dimensional) is the technology used by Aureal Semiconductor in their Vortex line of PC sound chips to deliver three-dimensional sound through headphones, two or even four speakers. The technology used head-related transfer functions (HRTF), which the human ear interprets as spatial cues indicating the location of a particular sound source. Many modern sound cards and PC games incorporated A3D via license from Aureal. Due to Aureal's acquisition (see below) the A3D technology is now part of the intellectual property of Creative Labs.
The technology was originally developed by Crystal River Engineering for NASA's Virtual Environment Workstation Project (VIEW). Crystal River later commercialized the technology with a series of products including the Convolvotron and the Acoustetron. Aureal acquired Crystal River in May 1996[5] and rebranded the technology A3D.
A3D differs from various forms of discrete positional audio in that it only requires two speakers, while surround sound typically requires more than four. The particular advantage of A3D is for dynamic or interactive environments such as simulations, games, video conference, and remote learning. A3D is not as effective for static productions such as movies which typically employ surround sound.
A3D uses a subset of the actual in-game 3D world data to accurately model the location of both direct (A3Dspace) and reflected (A3Dverb) sound streams (A3D 2.0 can perform up to 60 first-order reflections). EAX 1.0, the competing technology at the time promoted by Creative Labs, simulated the environment with an adjustable reverb—it didn't calculate any actual reflections off the 3D surfaces.

A3D was supported by 3DMark along with many other software titles of the late 1990s, including Half-Life, Unreal, Quake II, Soldier of Fortune, Jedi Knight, SiN, Quake III Arena (up to version 1.25), Unreal Tournament and Star Trek Voyager: Elite Force.
Following Aureal Semiconductor's acquisition by Creative, support for the API was discontinued.

Aureal is no stranger in PC audio market. In the past few years, they've rocketed themselves from being unknown to rivaling the popularity of Creative Labs line of sound cards. Before Aureal came around, Creative Labs was the only viable solution for decent performing cards that had the best compatibility around. I would venture to say that the biggest boost that Aureal got was from Diamond's MX200 (Vortex) and MX300 (Vortex2) excellent cards. These cards had the best mix of features, performance and price which made them very popular (especially amongst gamers) and brought Aureal into the limelight. In the last year, Aureal decided to go solo (like 3dfx) and manufacturer their own products based on their own chips. In this review we'll be taking a look at Aureal current top-of-the line card, the Vortex2 SQ2500 Quad PCI sound card. It's packed full of features, has a great software bundle and has the best 3D sound implementation available. So it should be no surprise to you (especially if you've seen other reviews), that we loved this card. In this review we'll be taking a look at this card using the new 2048 drivers with EAX support and the newest A3D drivers (currently 3.12). Lets start off by taking a look at it's feature set:
The specs are pretty decent, most of the features are pretty much standard other than the Dolby Digital 5.1 support. This is perhaps the most intriguing feature of this board and The Vortex2 chip has been used on many other cards in the past, so we all know that it provides great sound quality and some of the best 3D audio. Unfortunately, using 3D sound inflicts quite a hit on the performance of your system because it requires more processing from the Vortex2 and your system's CPU. The SQ2500 is the first card to uses Aureal new revision of the Vortex2 which is supposed to reduce CPU usage when 3D sound is in use. The new chips are labeled with a 'B0' instead of the old 'A2' you may have seen. We'll be comparing the CPU usage against a Diamond MX300 to see how much performance difference there actually is. This new revision also has a slight better signal-to-noise ration of 98dB as opposed to 96dB with the old chip. Besides the new revision of the chip, the card also has a Coaxial S/PDIF digital out port which is great for musicians who want to digitally output their music or if you want to output the audio signal from your DVD-ROM drive to your home theatre receiver. That way you eliminate line noise and are still able to send over Dolby Digital encoded material to be processed by your Receiver (if it has an S/PDIF in and a Dolby Digital decoder). If you require an optical S/PDIF out, you could buy a converter, but those usually cost quite a bit of money. Other than that, all of the other features are pretty much standard with all other Vortex2 cards, but still exceptionally higher than most generic PCI sound cards. For example, other than the Sound Blaster Live! (which even falls short in some cases), there aren't many cards out there that can boast a 576-voice wavetable synthesizer or 76 streams of DirectSound3D acceleration. Beyond that, Aureal's Vortex2 is the only card that is able accelerate A3D 2.0 in hardware. From what I've seen, no other card has A3D 2.0 support.
