I have an app that takes audio input from the bottom mic to figure out how hard you are blowing, which we then use to play music. We are trying to find a way to be able to use the mic by the camera on the iPhone 5. I can't find any apple documentation for it. Any help would be great.
Eventually discovered that you have to use the rear facing camera, to use the mic on the back. I heard this might be changed in the new release.
