A procedural audio simulation of the fluid dynamics underlying the water stream action. Naturally born for music, live events, film, tv and entertainment productions, WaterStream is based on a complex and powerful physically accurate particles collision engine - it does not use samples at all, sound and fluid dynamics are actually real-time generated. With WaterStream, generating realistic light rain, waterfalls, downpours, river flow soundscapes and much more is as easy as pressing a single note key.
