The first member of the line, the Vortex AU, was announced on July 14, [1] , and was used in by a number of sound card manufacturers, like Yamaha and Turtle Beach. Descent 3 sounded great, but liked to crash every 30 minutes or so. Got the same card, but just the bare card. The magic happens when you start using software that supports positional audio, in particular A3D 2. You can’t have more than 16 A3D 2. Nifty virtual reality systems with head tracking can beat this problem, but don’t look for one of them on the shelves of Clint’s Crazy Bargains at any point in the near future.

When you’re playing single-player, turning on 32 bit rendering and maximum quality everything and 3D sound helps you lose yourself in the game, the star of your own little studio-quality movie. To get surround sound from your PC into your home theatre system, though, you have to send a suitable signal to a surround decoder, which in most home theatres lives in the surround receiver. This page was last edited on 11 Julyat If you’ve got two spare slots, but they’re not near each other, you’ll have to shuffle your cards.

The OEM Montegos are a good buy – this is not one of those situations where the new gear comes out a week after you buy the older model, leaving you kicking yourself. The various presets can be further tweaked by changing the level of the reverb compared with the original sound, and the preset in use can be changed at any time, but EAX 1 has no ability to ahreal simulate how things would sound in care particular shape of room.

Driver for an old sound card

Older sound cards commonly provided accidental feedback on the status of the computer, with crosstalk from umpteen different internal systems clearly audible through the speakers whenever something loud wasn’t happening. The smallness of the MIDI format makes it possible for whole new scores to be squirted down the phone line in seconds, and huge amounts of music can be used in a game without using monstrous amounts of aureql for digitised samples.


If you want a big old home studio setup with all of those inputs and outputs, a Live! Different driver versions work, or don’t work, in drastically different ways; games that allegedly support one or another positional audio standard actually don’t do it properly, or at all; “fixes” to positional audio problems simply involve turning it off, and so on.

Aureal have been promising Vortex 2 drivers which support EAX for rather a while now, and should have working drivers out uareal.

Value Digital, both of which seem to have the exact same hardware as the US Lives but different bundles – the Value Digital is the cheap one, and should cost around the same osund the Quadzilla, if not less.

Many users don’t give a toss about MIDI either way, as they only hear montgo when they visit some dodgy Web page that insists on playing “Copacabana” in the background. Today, though, you can get real 3D sound, also known as “positional audio”. The Vortex chips are also good at keeping sound quality up aound they’re mixing lots of samples, because of their 96 parallel high quality sample rate converters.

A3D 1 and DirectSound 3D have no real idea what shape a room is – they only know where the sound sources are within it. You can help Wikipedia by expanding it.

Their technology ain’t new, but neither is it outdated, and a sound card that supports positional audio is worth a bit extra. What the difference between this card and the “quadzilla” package? If a system includes occlusion sound being blocked by objects and proper reflections, it has to know where walls and objects are, so the CPU has to provide geometry information to the sound card driver, as well as to the video card driver.

And the Vortex 2 hardware is clearly technically superior.

Two speaker positional audio is, of necessity, a compromise, because the programmers don’t know the specs of the speakers or their location relative to the listener. Driver used was probably this one: A plain surround system, with speakers behind you, gives you 2D sound, but with the help of fiendishly cunning HRTF Head Related Transfer Function algorithms, it’s possible for even dual-transducer systems a single pair of speakers, for instance, or headphones by preference to give a genuine impression of properly enveloping sound.


The results from this downmixing are usually disappointing, though. The alternative is performance loss.

If you’re shopping for a no-holds-barred PC sound card at the moment, a few more options are opening up. The Quadzilla requires you to screw the daughter card into a slot somewhere close to the main card and hook them up with the provided cable, but this is easy enough – provided, of course, that you have enough spare slots for both boards. You only get one MPC2 audio cable, though, so if you want to connect more than your CD-ROM’s audio output to the sound card you’ll need to pick up extra cables.

AudioStation 32 – behold! Got the same card, but just the bare card.

Mixed up in the positional audio concept is simulation of particular audio environments – aureeal different reverberation and occlusion characteristics of different places. The Vortex 2 chipset won numerous industry awards, and was used among other places in the Diamond Monster Sound MX, which achieved near-cult status with audiophiles and gamers for the high quality of its positional audio.

They work fine with the Montego and Montego II. The Montego II board that comes in the Quadzilla package is exactly the same as the standard Montego II, but it comes with the “daughter card” expansion board that’s an extra-cost option for the cheaper Montego II.
