This is a visual description of an electrical representation of the acoustical signature of my Model A.
I used the exhaust area to record. Notice only the amplitude changes not the frequency.
Just thought it would be of interest

Don't know much about a Model A engine's exhaust acoustical signature.

But for something to talk about:

Maybe some future whiz kid may be able to computer analyze Model A engine problems with such a device to record Model A engine flatulence.
 
After all the comments from people who say that they love the sound of the Model A, I thought maybe someone else may have scoped their car and could compare their sound pattern to mine. Has this not ever been done?
 
It looks a lot nicer than mine. But the recording instrument you're using is probably a lot better than an old Android phone.

Plus, my truck only warmed up for 30 seconds. It could be a little rough, as evidenced by the irregular peaks and troughs.

Old stocker, Sears rebuild, no extra goodies. Can you hear the Puckita-puckita-puck?

Interesting.
What rpm (roughly) was the recording made at?
