I have an HTC Thunderbolt (ADR6400L) which has two mics. One is located on top and one at the bottom. I plan to use tBolt to record band and RecForge asks me which mic I would like to use. Do these mics both have same specs? Band will obviously create clipping since I have no way to control input gain. I can't find much info at all except for the fact that tBolt features noise cancellation technology (1 mic or both?). Any suggestions about which mic to use?
