Recording volume too low on iPad.
I have been trying to record as I play on my electronic keyboard. The mic level on my iPad 4 seems to be too low. There is no way to adjust it either. Even after putting the keyboard volume to max and setting the iPad on the speaker with the mic facing down into the speaker, the recorded sound is extremely quiet. It isn't a hardware problem since I can use FaceTime, dictation, or record audio with other apps without issues.
I noticed many reviews in the app store complaining of the same issue. It seems to be mostly iPads. There are people that specifically mentioned having problems with iPad 4, iPad 2, iPad mini 2 and iPad Air. Some said they did not have the same issue when using their iPhone 6, or iPod Touch. Any thoughts or suggestions?
