I wonder if it gives an exponential with a modified decay time. You can use the acoustic entry to make this experiment but where take a square wave generator? Also using the sound card?
What about the rotation of a small electrical motor? Would that be linear?
Regardless, the first try with discharge over an purposely unbalanced motor shows a decreasing frequency that looks like it's exponential (which it should).
