here's a quickie tutorial I just did with regards to how I use the Waves doppler plugin to make bys out of steady onboard vehicle recordings. In this case I used the onboards that I recorded of my motorcycle a few weeks back.
Structurally, the concept draws heavily from Charles Deenan's 100 whooshes in 2 minutes tutorial on designingsound.org
The main change I made to his process was to really work the ins and outs of each by using the faders.
Some things I didn't really discuss, but you can see how they would work
are the fact that you can make stylized whooshes with this technique as
well. That 100 whooshes post goes into great detail on that, though my preference is to go a little more focused than what Charles does. For example, I'll substitute a bunch of bow waves and streams running, and get a bunch of underwater waves going on.
In the vid I'm using a controller instead of a mouse to move the faders (so that I can move several simultaneously)and I'm performing the moves in real time.
skip the first 15 seconds or so. Vimeo seems to have a pause glitch in there.
My two wishlist items for doppler would be an option to make it stop at the end of the path, and 96k support.
