When I design SoundSets for Syrinscape, my longest loops are generally VERY plain wind loops or general background hubbub sounds that last for about 5 minutes. These have NO obvious foreground features and thus can go round and round and round with no prob…
THEN on top of that we add, dog woofs, or thunder, or comments by passing people or birds or cash registers or coffee machines or whatever… and these are what catch the ear. And since they are one variable timings all on separate element layers… that’s where we get our variability.
Sense makes?
