Extended Hardware Effects 

The Sound Blaster® Audigy®, Audigy 2 and Audigy 2 ZS have extended effects, previously only used in music creation (Flanger, Echo, Distortion and Ring Modulation). EAX® 4.0 ADVANCED HD™ can now tap into these effects for real-time manipulation of audio streams that allow developers to create new and unique audio effects in games, such as alien voices or robotic sounds in real-time.
