With the left swipe menu, you can manage video and audio source.
If you connect your device with the smartphone microphone jack, it will be AUDIO 1.
If you connect your mic with your external device(DSLR, camcorder and so on), it will be AUDIO 2.

We are trialing your excellent CameraFi app for live streaming events. How can we use an external microphone with it? We have a headset adapter and can physically connect the microphone to the Android device, but don't know how to turn the internal mic off. Thanks.
