This is a rainy electroacoustic soundscape using no watery samples at all, just random sounds from my apartment. I created this for my electroacoustic portfolio that I had to submit to a university I was applying for, and I got in!
The criteria was to basically showcase your sound-manipulation skillz, and making water out of spoons, chairs, and paper requires some of those skillz. Here's what I used:
Low rumble at the beginning - a paper bag with the lows enhanced
Car passing by - guitar string
Hard drops - metal spoon hitting a plate
Thunder - the same paper bag
Other drops - spoon hitting a glass, my doorchain rattling
All the sounds were recorded with my mp3 player around my apartment, then heavily processed in Fl Studio. :D
