The step is system independent.
On Windows you can use Virtual Audio Cable or VB Cable. Both software will install virtual input and output audio devices on your system. After that map the output player device to the input mic device so any audio our app played to the device is transferred to the virtual mic device.
On Linux you can use pulseaudio to create a virtual mic device.
3. Choose a connection method: This is how your phone will be connected to your PC and stream audio from the mic.
For TCP & UDP, connect your phone and PC to the same internet.
For USB serial, connect your phone to PC with a cable.
