D.2b Getting QEM™ to work on an “EAX™-ENABLED” DirectSound™
Game
(See Figure 2)
“ EAX™-enabled ” is a term used for games/applications that have been
programmed to take specific advantage of EAX™ technology. These games use
the EAX™ API to make calls regularly throughout the program to change the
current environmental effect, as is appropriate to the current in-game scenario.
Here’s a typical example of what an EAX™-enabled game would do: If the current
scenario in the game is a cave-like setting, the game will automatically select the
“ cave ” environment preset from the Default Environment list (this all happens
internally, so you won’t see anything changing in the control panel) . If the player’s
character then moves into a larger room , the game might then call for an
“ Auditorium ” environment preset, giving the overall impression that the player
has indeed entered a large room.
In other words, an EAX™-enabled game will automatically select the appropriate
environment from the list (excluding the special “game-specific” presets for non-EAX™
games) , and will keep doing this throughout the game.
(If you manually selected a preset from the list, any EAX™-enabled game you play subsequently
will make its own calls that will override the setting you have selected.)
Some examples of EAX™-enabled titles on the market are, Unreal (updated with
the most recent patch) , Half-life , and Jurassic Park: Trespasser .
