If you have a device with two microphones, you can select which one to use. Sometimes just using Default will do some counterproductive extra audio processing, even though you have chosen Unprocessed in Audio Source. Then choosing either First or Second from the Channel Select menu will help you to improve the audio signal. There really is no way to figure these settings out in a programmatic way, so you have to play with those settings until you find the one that works best.
