Thanks Drew. That's exactly want I've resorted to, using Audacity to record, then boosting the signal. There are no high peaks when recording, just low levels uniformly across the whole waveform. It's a PITA tho, to have to do that, then paste each track into iMovie. Using the usb mic at high gain is picking up breathing, and the internal mic does a better job, just too low.
