Three tips to maximize audio quality of iPhone’s built-in microphone:
1. Where is it?— On an iPhone 4, the microphone is on the bottom of the phone. If you lay your phone on the desk, the mic is the oblong hole, with a fine screen over it, to the left of the charging port. The oblong to the right of the port is a speaker.
2. How far? — The built-in microphone of the iPhone will pick up a lot of natural sound, in addition to the person you’re interviewing. I place the iPhone about a foot in front of the interviewee’s mouth to get a good blend of voice and natural sound.
3. Can you hear me now? — The mic built-into the iPhone is more finnicky and susceptible to wind noise than a typical broadcast microphone. Windscreens built specifically for an iPhone are hard to find and overpriced. Buy a foam windscreen for a standard microphone for a couple bucks — the iPhone will fit inside snugly.
