I normally use BirdNet app for birdsong, and it looks like that is from Cornell as well. Does Merlin use the same tech under the covers?

I don’t believe so. Merlin is newer and uses a different architecture. BirdNet uses a CNN and its atomic sound units are 3 seconds long: Merlin can do real-time ID on continuous audio and I think uses a hybrid system.
