How does noise-cancellation work in Mac laptops?.
I understand how it works in Headphones or even in iPhone. But if the mics in a MacBook Air 2018, for example, are located in the same spot, what is being cancelled there? How can a plane motor or fan buzz be cancelled this way during a FaceTime call or similar?
This is set up in System Preferences > Audio "Use Ambient Noise Reduction"
Any resource explaining this?
Any help much welcome.
