I am trying to make a swishing sound by pulsing a pin and feeding it thru
an RC into an amplifier. I want it to be kind of like a hiss with a gentle
rise and fall. Not unlike a car approaching and then leaving but as a hiss
not a roar. Anyone have any solution to keep me from reinventing the wheel?
I think it would be a great effect for a swinging pendulum in a haunted house.

so far I've had a couple of replies.  Unfortunately the best response was a
method of playing back three recorded sounds but what I am looking to do is
to simply generate a sound effect by perhaps varying the parameters on one
of the PWMs.

Thanks again.
