OpenAL 2.0 и EAX 5.0
которые поддерживает эта карта - именно это и включают.
отражение, прохождение, смешивание звука соседней комнаты со звуком текущей. т.е. если у тебя грубо говоря рядом со зданием стреляет танк то внутри здания должно гулять эхо, причем слышать ты должен и эхо и чистый звук, если ты стоишь перед дверью и видишь танк визуально.

EAX® ADVANCED HD™ 5.0
Chosen By Games, Loved By Gamers
Since its introduction in 1998 EAX® has delivered incredible real-time environmental audio to millions of gamers. EAX® stands for Environmental Audio eXtensions and is a programming interface that allows developers to access the special features of Sound Blaster® cards. This allows them to add ultra-realistic and incredibly immersive audio to games! Today there are over 400 EAX® titles ranging from EAX 1.0 to EAX ADVANCED HD 4.0 and each level adds more features and more realism for gaming.
So now, to exploit the full potential of the Creative X-Fi Xtreme Fidelity Audio Processor we have developed a new version of EAX.
This latest addition to the EAX® family delivers a number of new features that will drive gaming audio to a new level. It delivers double the voice count, so you get more detail and speed in your games. Developers can also add interactive music to games. EAX® ADVANCED HD™ 5.0 also adds a dedicated bass feed for each of the 128 voices, so gaming audio becomes more cinematic. Next you get Environment FlexiFX™, which gives developers total freedom to use any of four simultaneous effects with any of the 128 voices. Finally EAX® MacroFX™ allows EAX® ADVANCED HD™ to simulate sounds passing very close to you!
Environment Occlusion™
OK, The Bad Guys Are Outside!
This feature makes gaming audio more realistic by recreating the effect of sound from adjacent environments passing through solid objects. It can even recreate how different materials affect sound, such as wood vs. brisk vs. stone and has been enhanced to be even more realistic than previous versions! This allows you to tell when a bad guy is outside the room you are in rather than inside.
Previous versions of EAX® supported a feature called occlusion. This feature recreated the effect of sound passing through a solid object (see the other EAX® sections for a detailed description). However the basic Occlusion effect only occluded the direct sound, but not the environmental reverb associated with that sound. This reduced the effectiveness and impact of the overall effect. Environment Occlusion? improves the realism by allowing the reverb effect itself as well as the direct sound to be muffled due to occluding objects. So you get the best simulation of real-world audio ever achieved!
Conclusion
These new features in EAX ADVANCED HD 5.0 will drive a whole new generation of games with the most realistic and engaging audio ever for a gaming experience that will send shivers down your spine!

QUAKE 4™ is also the first game to fully utilize the new EAX ADVANCED HD 5.0 feature set. QUAKE 4™ is a great game for hardware reverb effects, because it has a great variety of indoor and outdoor areas and the transitions it makes between areas are fantastic. With access to 4 simultaneous reverbs the game can practically assign an individual reverb to each sound and give it a custom effect. This is great for the situation where you have the listener in an outdoor environment and there is a Strogg guard walking around in an enclosed Strogg hangar. The sounds made by the guard walking in that hanger will have its own hangar reverb applied to it to help locate the enemy, and the sounds made by the player outside will have their own outdoor reverb effect applied to them. This adds a whole extra level of interactivity and diversity to the sound design which allowed the developers to really affect how the game sounds as the player moves through the levels.
QUAKE 4™ uses another feature of EAX 5.0 called occlusion. Occlusion simulates the effect that a closed door has on sounds. When a sound is created on the other side of the door (i.e. a grenade exploding) and the door is closed the explosion sound is muffled. This really helps out in QUAKE 4™ because it is easier to hear from what direction the sound is coming and on which side of the door it is.
The carefully crafted sound design of QUAKE 4™ combined with the cutting-edge technology and hardware acceleration of Sound Blaster X-Fi has created a truly breathtaking gaming experience. Fight the Strogg with the enhanced abilities of Sound Blaster X-Fi and turn the tide of war!

скажу честно - QUAKE 4 - единственная игра, в которой я реально почувствовал мощь X-Fi. Остальные игры под X-Fi не заточены.

НИЧЕГО ЭТОГО в ИГРАХ НЕТ!
P.S. Аудиокарточка сама не считает отражение от стен. Она ЭМУЛИРУЕТ окружение которое должно быть аккуратно прописано дизайнерами уровней, и включено в аппаратную обработку для EAXa.
P.P.S. Где-то лазя по креативу я находил видео демку игры шутера, где аккуратно сделан звук. Специально для EAXа. Вот там меня впечатлила обработка.
Вполне возможно что современные процы стали настолько мощны, что не нужен им никакой внешний процессор для быстрого просчета звука. Они и сами с нужным софтом справятся. Я согласен. Но тогда зачем нам Х-Fi?
