Why does adding more cameras increase noise cancellation?
Did you mean "adding more microphones increase noise cancellation" in your title? Yes, multiple mics can reduce noise. And your suspicion that they can "focus" on your voice *is* in the ballpark.
The Short Answer
Did you mean "adding more microphones increase noise cancellation" in your title? Yes, multiple mics can reduce noise. And your suspicion that they can "focus" on your voice *is* in the ballpark. What they do is have one microphone aimed in the same direction as the camera, and one on the top or off to the side. The computer on the device then compares the audio from the two, and deletes what matches. Since *both* mics would hear wind and noises but *only one* will hear voice, only the voice track is left.
