Hi all,

I'm doing a project in a DSP class to determine the speed of a vehicle
(like a car) based on just the sound which a stationary observer would
hear as it passes. I have a vague recollection that something similar was
mentioned here, but I can't find it in the archives.

Most importantly, I'm looking for recordings of various vehicles which
are going at a constant speed while passing, and (preferably) at a known
speed. So far, I have only found a few sounds of racecars passing, etc.,
but very few are going at a constant speed (I can hear them accelerating
and changing gears).

Thanks,

Sean
