I've listened to the sound clips a few times and it is interesting that the pitch changes. Pitch is higher when revs climb, and then a little lower as revs fall, which I assume means the change is from being on throttle vs. off throttle (or on boost vs. off boost?). Volume is roughly the same, only pitch changes. Hhmmm.
