So I've edited a few tastes of the rough sketch for the particle sounds. There's a lot of background noise because it's a nice day outside, and I wanted to test the first run outside where I can let the particles scatter all over and make a nice mess for the squirrels to clean up!
Now that I've narrowed down possibilities, I can do some re-takes in a quieter environment.
Here's a few compressed samples:
Flax seed on cardboard with the U87 & 702T
Flax seed on tent with the H4 stereo mic/recorder
Sesame seed on tent with the H4 stereo mic/recorder
Sesame seed on cardboard with the U87 & 702T
Have a listen-- You'll have to imagine the results of an indoor session when the mic can be a little farther back from the surface.
I also still have to figure out a way to have a somewhat regular dispersal of the material onto the surface--dropping it from my hand is too irregular and risks clumping sounds. Any ideas? Unfortunately a fan makes too much noise. I'm thinking a funnel might work....
