5 point virtual surround sound with your sblive, audigy or audigy2
You own a cheap sblive, a normal stereosystem and cheap headphones?
Still you'd like to experience positional audio in your games or if you watch a DVD?
You don't need to buy a new 5.1 system, you neither need to buy a set of those expensive 5.1 Headphones,
you just need to download the kx-drivers for your operationsystem (available for win9x and winxp) and get this effectplugin here: plugin for kx-drivers
If you encounter problems installing the kx-drivers, check the forum linked at the kx-project site,
there is also no warranty or support for the surroundplugin as it's totally free.
The HRTF-data is derived from the kemar data, although it's far from being as accurate.
