The iPhone 4 has two built-in microphones: one in a standard location and one sitting next to the headphone jack. I know that this new microphone is used for noise reduction in calls, but it is also used in factor, video, calls, etc.
I have a good reason why I want to choose which microphone to record, whether new or old And even at the same time.
Does anyone know how to redirect avaudiorecorder so that I can select any of the above options for what is being recorded?
Thanks in advance
