What type, or at what caliber do outgoing shells audibly whistle?

I've watched various footage of large caliber guns firing. On watching large German coastal emplacements in France firing on Dover, I noticed a loud whistle as the shell left the breaches of 12in+ caliber cannons. I've also seen footage of American 16in and 5in guns firing, and have not noticed the whistle. At what caliber will an outgoing shell do this? Is this a result of specific German design in their shells? Is this also normal for smaller calibers, like 5in, 6in, or 8in guns?
