Although I know I probably could buy a microphone that does some of what I'm wanting to do much better, I am wanting to experiment with building some audio capture hardware from spare parts gained from tearing down broken devices. I may mostly be using dynamic mics from small (1.5 inch or so) speakers as my primary pickup. My goals are simply to get the best sound I can, whatever that may be. What are some ways of improving the response of most mics? I'm guessing that using speaker tuning methods, such as a resonator chamber, packing, ports, etc will make a significant difference. I have also been looking at shotgun mics lately as well as cartioid and omnis.
