Positional audio can be done partly or entirely in software – DirectSound 3D implementations commonly do this, when they run out of hardware 3D channels or are running on hardware that has no built-in 3D capability. 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. But you probably don’t. The Montego boards, like every other good sound card these days, deal very well with the hugely electrically noisy environment inside a PC case. EAX actually doesn’t have anything to do with positional audio – by itself, it’s just reverb, and a game must also support DirectSound 3D if sounds are to come from particular locations.

A great deal of the processing for positional audio is done by the custom processor on the sound card, but the CPU has to help, especially with more advanced systems like A3D 2. Of course, in this sort of bunfight you’re less likely to notice if most of the sounds have dropped back to plain stereo. This page was last edited on 11 Julyat The price of this, though, is a big CPU load.

Turn around and everything’s backwards. D irect M emory A ccess, the act of directly moving data from a device to memory without passing it through the processor.

They also have to include “crosstalk cancellation”, to try to minimise the amount of sound meant for one ear crad makes it to the other. Q3A supports A3D 2. PC sound cards have on-board Soknd music capabilities, and can also have a special cable connected to their joystick port to allow the connection of external MIDI devices.

It’s not a proper sequencer, it’s just an instrument rearranger, but it’s handy nonetheless. The only full app in the Quadzilla package is Hip Hop eJay, one of those mix-up programs that anybody with Beastie Boys fantasies will probably like.


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. 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.

A3D see belowthough, has had hardware voice management for a while now. Incidentally, if you install the full reference driver suite, you get the most up-to-date A3D demos, including the Rooms demo monrego is missing from the plain Turtle Beach CD.

If your sound card has positional audio support built in, it may still use a lot of CPU time, depending on how much of the thinking it can do for itself. In this context, MPC2 just describes the kind of connector used by various sound cards for internal analogue audio, for instance from CD-ROM drives and internal modems.

If you’ve only got a two channel Montego or Montego II, though, there’s a lot augeal be said for the reference drivers. The performance hit can be reduced with clever driver coding – with each driver release, Aureal and the other companies that have Vortex boards speed the cards up a little – but the basic problem remains.

Views Read Edit View history. Understanding positional audio “3D sound” is a tarnished term.

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 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. It’s not perfect, but it’s very good.


Users browsing this forum: 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.

Back in two channel mode, headphones are the way to go. This is par for the course in the 3D sound world at the moment, unfortunately. The Vortex audio accelerator chipset line from Aureal Semiconductor was designed to improve performance of their then-popular A3D audio technology.

With 64 hardware MIDI voices and up to another with software mixing onlyfrom earlier driver versions such as come with the Quadzillathe Vortex 2 can handle arbitrarily complex compositions. Mixed up in the positional audio concept is simulation of particular audio environments – the different reverberation and occlusion characteristics of different places.

You have to turn on A3D in the setup menu every time you run Q3A, and it still seems prone to crashing now and then, with the current v drivers. That’s three real dimensions – forward and back, left and right, AND up and down. With DirectX 7, DS3D has hardware voice management support, which allows this nasty mixing to be minimised by feeding the important sounds to the hardware 3D sound streams.

CPU usage is the main downside of positional audio.
