guess I've found a good starting point for bubbling:
pink noise --> plugin called "Hysterisis" --> preset ASD_Juicer
pink noise --> plugin called "Molekular" --> preset Sheperd_Sortie
had to tweak stuff but those, for whoever is interested, is a good starting point for synthesized water bubbling
When you say "artificial soundscape" does this mean you can use anything BUT the sound of water? So, you couldn't record different kinds of running water sounds? Instead you would have to create that sound with an alternative source?
I suppose the question I would ask myself is "what does running water sound like?" I think that's a very loaded question. ...
