Having just been to an airshow (for the first time....Whoa!), and getting to hear the sweet pounding of Merlins, got me interested in high quality recordings of those sounds.
I've heard of the "Round Sounds" series for a variety of radial engines, and I tracked down a 2 disc set of internal and external sounds for the Corsair. But I can't find anything comparable for inline engines like the Merlin, the Allison, etc.
And then I realized everything I found considered only US products. I did come across an archival recording set in the library's collection following a Lancaster mission, but while its very cool, the sounds are definitely low res.
Are there modern products across the Atlantic that do for you folks what the "Round Sounds" do for us?
