Audio
Apple now promises “five studio-quality microphones” in the new iPad Pro (emphasis ours), and while it’s unclear what this means, it does suggest that they’ve improved the microphone hardware a bit, which should not only help FaceTime calls, but could also see its way into AR applications that require accurate recognition and spacial placement of ambient sounds.
Beyond that, however, it looks like it will support the same four-speaker audio output as the previous iPad Pro model.
