Tried using FaceTime Audio this past week because I have horrible cell reception in my bedroom but wifi works great. Called a friend who was in his bedroom, there was a movie playing in his living. I could barely hear anything he said, and the movie was coming through loud and clear. He said he's noticed the same problem with all facetime audio calls that he makes, the background noise is amped rather than cancelled. Apple has some pretty great noise cancelling mics in their phones, any idea why they're not utilized for facetime calls? We both use iPhone 5.
