Yeah, i thought so. Did you do a "save as" on the file?

Sometimes it does it at idling. This particular recording was taken
when it was idling, which I thought would be the best time as then
there's
no wind and I could also get out and stick a recorder underneath the
car
(of course this was done on a home driveway and not on a road with
other people driving on it) allowing for a crisp and sharp recording.
I
was trying gear shifting to see if that would provoke it, and it
seemed to
be happening then but I'm not sure how well it correlated with that
gear
shifting as on most shifts the sound didn't appear. I'm not sure
exactly
where it is coming from.

Other times it will happen on the road, with more clicks at a somewhat
more
rapid pace -- the third clip is a simulation made with the sound from
the other
clips to approximate it, as I'm not sure how I could get a good
recording
on the road with the wind and all that. I've thought of strapping a
recorder
or a mike to the underside of the car. Might give this a try and see
what
happens, if I can get a battery powered recorder to which a mike can
be
attached.

You know you could put your head down near the ground and use your ears
to determine where the noise is coming from. For all we know this could
be a squirrel in the trunk that makes a noise now and again.

I think it might be this...

I.e. it's really that much of a stumper. But thank you for trying to
help.
