On iPhone, how do I choose which microphone to use?
On my iPhone, I need to record my voice with the built-in mic while listening to a backing music track on my headphones.
Now, when I plug in my Apple-provided earbuds (with cords) which also have a mic, audio input switches to the earbud-mic. This is not what I want. How can I choose the input device?
The app I’m using is "The Virtual Singer", which doesn’t provide dedicated audio input selection.
