As processing power increased dramatically in the 6th generation of home consoles, it became possible to apply special effects in realtime to streamed audio. In "SSX", a recent video game series, if a snowboarder takes to the air after jumping from a ramp, the music softens or muffles a bit, and the ambient noise of wind and air blowing becomes louder to emphasize being airborne. When the snowboarder lands, the music resumes regular playback until its next "cue". The LucasArts company pioneered this interactive music technique with their iMUSE system, used in their early adventure games and the "Star Wars" flight simulators ' and '. Action games such as these will change dynamically to match the amount of danger. Stealth-based games will sometimes rely on such music, either by handling streams differently, or dynamically changing the composition of a sequenced soundtrack.
