Binaural audio is an immersive 2-track mix that can be listened to using headphones or earbuds. It reproduces the way we hear the sound with our ears in the real world, that is why it creates the illusion of space and sounds coming from different directions. For Dolby Atmos, it creates a similar sound in your ears as if you would listen to a Dolby Atmos mix using a proper 3D speaker set-up. Binaural mixes are created directly from the Dolby Atmos mix.
