Xhun Audio has released WaterStream, a procedural audio simulation of the fluid dynamics underlying the water stream action.
WaterStream is based on a particles collision physics engine - it does not use pre recorded samples at all - sound and fluid dynamics are actually real-time generated.
They say:
Naturally born for music, live events, film, TV and entertainment productions, WaterStream generates realistic light rain, waterfalls, downpours, river flow soundscapes and much more.
