I'm not going to guess on what the doppler effect is, as speed unknown. Assuming a gear change at say 7,000rpm, next gear is 5,600rpm. That is quite a long gear spacing if from 3-4th on a 7 speed box.

Little movie I took in the M6, very similar. Forward to 27 seconds.

Yep, that sounds about right.
