Isn't that more of a case of a Doppler effect being marketed as being a 
vibrato effect ?... An actual vibrato effect wouldn't change the timing of 
the note, for example, but it's the kind of thing you have to apply in the 
device that makes the note, so, if your input is an already-synthesised 
note, the easiest you can do is pass off the Doppler effect as a vibrato 
effect and get away with it because it sounds close enough.

(i'm only talking about the mono case here, no panning.)
